Power requirements

The guide values are for drilling alloyed

steel 800 -1000 N/mm2

and can varyfor other workpiece materials and tool

conditions (wear).

Coolant values

Sufficient coolant must be supplied to

the tool for troublefree chip removal.

Cutting data

Guide values for cutting speed and feed rate are shown in the table. As there are many factors that can affect the results

of deep hole drilling, these values must be correted if necessary.

Adjustment of tools

Drill heads will be adjusted to the ordered drill diameter in-house. Stop plate thickness "S”is engraved into the drill head body (see below)

Procedure:

Tools can be adjusted in diameter by using guide pad shims and exchanging the stop plate.

The maximum adjusting range is 0.25mm diameter.The thickness of all guide pad shims must be exactly the same.

The exact drill head diameter D1 is adjusted by exchanging the stop plate.

The difference between D1 and D2 must be at least 0.02mm and at most 0.06mm.D1 should be always bigger as D2.

Example:

The drill head 64-1121-000 with D1 = 45.00 should be adjusted to D1 = 45.22 mmEngraved in the head is a stop plate thickness S = 1.51 mm for a drill head diameter 45.00 mm.

For adjusting the drill head to the new diameter guide pad shims # 10-0800-4919/0.1mm thicknessand a stop plate # 01-2050-610-S1.63 are used.

Technical informationfor solid drill heads type 12 and 64

Type 12 and 64 are high-precision deep hole drilling tools with indexable inserts and

guide pads for use on deep hole drilling machines with BTA (STS) drilling system.Adjusting of tool diameter in increments of 0.01mm by changing inserts and puttinga shim underneath the guide pads.

The tools do have an adjusting range within 0.25mm (..,00 - ..,24mm) (..,25 - ..,49mm) (..,50 - ..,74mm)(..,75 - ..,99mm). For the smallest diameter of each drilling range no guide pad shims are used.

Tools with adjusting range (..,00 - ..,24mm) are available in a few working days.

Stop plate system

When using identical tools with exactly the same drill head diameter, the thicknessof the stop plate (dimension "S”) can vary due to manufacturing tolerances of themilled drill head body.

The needed thickness "S” for the ordered drill head diameter is therefore engraved

Information about botek solid drill heads Type 11/Type 61

- The chip breaker has a decisive part to play with the chip formation.

- To obtain trouble-free chip flow along with optimum tool life, it is essential to aim for the most ideal chip formation possible.

- The chips should be broken just short enough to ensure that there is no chip congestion in the flute or the drill.

- Excessively short, crushed chips place strain on the cutting edges and lead to premature wear and will destroy the cutting edge.

- For processing commonly used materials, indexable inserts are available from stock with chip breakers SP 1 or SP 2.

Application requirementsfor carbide twist drills

D

1,5-4xD

D +0,01/+0,02

Conditions for successful deep hole drilling:

1. An efficient coolant and filtration system with a filtration of 20 µm to 30 µm(the smaller the diameter, the better the coolant and filtration should be).

2. Suitable coolant, i. e. deep hole drilling oil or emulsion (min. 6 % concentration,with additives) has to be provided in sufficient quantity and pressure.Minimum quantity lubrication (MQL) is also possible.

3. Guidance with a pilot hole in the workpiece.

Machining sequence:

1. Drill pilot hole(for size see table “Dimensions for the guide hole”).k We recommend to use botek pilot drills Type 153

2. The twist drill is fed into pilot hole while non rotating

or rotated slowly at < 200 RPM.3. Switch on the coolant.

4. Switch on RPM and feed.

5. After reaching the drilling depth switch off the RPM.

6. Switch off the coolant pump.

7. Fast retract with the spindle stopped or slowly rotated< 50 RPM. Please see our safety instructions (page 9).



Angular drilling

1. Spot facing.

2. Drill pilot hole (for size see table “Dimensions for the guide hole”).k We recommend to use botek pilot drills Type 158

3. The twist drill is fed into pilot hole while non rotating or rotatedslowly at < 200 RPM.

4. Switch on the coolant.

5. Switch on RPM and feed.

6. After reaching the drilling depth switch off the RPM.

7. Switch off the coolant.

8. Fast retract with the spindle stopped or slowly rotated < 50 RPM.

The mentioned values are guide values. The maximum possible values depend on the diameter and length ratio of the tool.

The carbide twist drill is a self centering drilling tool. However, a guidance by means of a pilot hole is necessary. Drill lengthsexceeding 15 x Dia., high feed rates while drilling and the resulting deflection forces might cause tool breakage.

Quality and accuracy of the pilot hole affect tool life and centreline deviation.

Guide values for processing various materials with carbide twist drills (coolant fed)

Please note:

- The recommended values given in the table above only apply when using hydraulic chucksand providing good chip removal.

- Feed rates set to achieve short chips.

- Reduced feed rates for interrupted cuts (hole exit, angled exit, etc.).

Drilling quality

To achieve optimum drilling results when using solid carbide twist drills, various criteria must be applied.In addition to tool design, key factors are machine design and construction, process techniques, pressurized and filtereddeep hole drilling coolant. Selection of proper cutting parameters is also a significant factor.

The key factors botek considers when designing gundrills:

- Material type

- Diameter, tolerance and surface finish

- Suitable carbide grade

- Nose grind geometry

In addition to our refined manufacturing and technology for consistent product quality, our application and technicalexperience help you realize optimal solutions.

The gundrilling process

and the requirements for application

The characteristic of the single flute gundrilling process is that coolant is fed through the coolant hole in the tool and exits along with

the chips in the V-shaped groove (flute) on the drill tube from the drilled hole. The coolant also provides lubrication to the drill periphery.This is possible if coolant, i.e. deep-hole drilling oil or emulsion (min. 10 - 12% concentration, with additives), is provided insufficient quantity and pressure (coolant information see page 18 - 23).

Minimum quantity lubrication (MQL) may be used under certain conditions.

High pressure coolant systems should already be integrated in the machine or can be provided as a separate unit by themachine’s manufacturer. Economical deep-hole drilling is therefore, not only possible on special deep-hole drilling machinesbut also on CNC machining centres (lathes, horizontal boring machines, etc.).

Information on the guide hole (pilot hole)

with drill bush

with pilot hole

The gundrill is a single-edged toolwithout self-centering.When positioning the drill, the tool must be guided through a drill bush or a pilot hole.

The quality of the pilot hole affects the drillingperformance (tool life, centerline deviation, etc.).

Overview

Nose grind geometry

The nose grind geometry affect the following, hole tolerance, chip formation, coolant pressure and flow, tool life, centerline deviationand surface quality. Over the years, botek has successfully tested a number of different nose grinds for drilling various materials.

botek`s experience has formed the foundation for the development of our standard nose grind geometries. This meets the require-ments of most drilling applications. Deep hole drilling of especially long chipping materials and difficult to machine materials usuallycall for special nose grind geometries, and in some cases, made to order chip breakers, all available from botek.

Nose grind no. 002 (SA-0002)for drill range: 4.001 - 12.000 mm

Tool design

Drill tip and drill tube are manufactured from a single piece of carbide blank. The advantage of this tool is high processreliability and performance. Longer tool life is possible because of reduced torsional vibrations and higher rigidity.

With this tool type, the driver (steel) has a ”pin”. The driver and the drill tube are connected by a brazed joint.

Driver

botek solid carbide gundrills are made complete with drivers. Drivers transmit the torque from the machine to the drill.High rotational accuracy between the drill shank and the driver avoids additional vibration, thereby increasing the cuttingperformance and process reliability of the tools. In addition to a large number of standard drivers, botek manufacturesdrivers also to customer specifications.

Cylindrical drivers (DIN 6535 HA) used in hydraulic chucks or sealed collets achieve best true running, typical onmachining centres.

1. Drill head

a) Peripheral contour

The single flute gundrill is selfguided while drilling. Guide pads on the drill head act as supports. The layout of the guide pads oftenhas a decisive influence on the surface quality and dimensional accuracy of the drilled hole. Cutting forces press the guide padsagainst the hole wall with force that a burnishing effect occurs, producing the surface quality and dimensional accuracy (roundness)typical of the gundrilling process.

Various contours (see page 12 +13) are available to suit your drilling requirements.

b) Nose grind geometry

The nose grind geometry affect the following, hole tolerance, chip formation, coolant pressure and flow, tool life, centerline deviationand surface quality. Over the years, botek has successfully tested a number of different nose grinds for drilling various materials.

botek‘s experience has formed the foundation for the development of our standard nose grind geometries. This meets the requirementsof most drilling applications.

2. Drill shaft

Tempered alloy steel tubing is formed with a V-shaped groove (flute) to create the swarf (coolant) return channel required for the

gundrilling operation. Design considerations for proper drill tube sizes include the ratio between the drill tube outside diameter andinside diameter for optimum torsional rigidity. This ensures exceptional cutting performance, coolant flow and tool life.

With standard gundrills the ute section is typically extended to the driver. For longer gundrills it is possible to have a round section of drill tube with a shorter flute length for added rigidity and strength.

Technical Information

Drilling quality

To achieve optimum drilling results when using carbide tipped or solid carbide gundrills, various criteria must be applied. In

addition to tool design, key factors are machine design and construction, process techniques, pressurized and filtered deephole drilling coolant. Selection of proper cutting parameters is also a significant factor.


- Material type


- Peripheral contour

- Carbide grade and coating


In addition to our refined manufacturing and technology for consistent product quality, our application and technicalexperience help you realize optimal solutions.

Drilling quality

Centerline deviation (drift)

Counter-rotation: The optimum results are achieved with rotating tool and simultaneous workpiece counter-rotation: See ”Z”

Workpiece rotating: The next best technique involves the workpiece rotating with the gundrill non-rotating: See ”Y” Tool rotating: See ”X”

In all applications tool drift is minimized by using a close fitting pilot bore or guide bushing during gundrilling.Angular alignment of pilot bore with desired gundrill bore is imperativ.

With a guide bushing, alignment and distance from the workpiece are also important.

Roundness

Hole roundness is a primary advantage of gundrilling over conventional twist drilling.Hole roundness measurements as low as 3 µm are possible.

The data above is based on single flute carbide tipped gundrills. Achieved results may be improved usingsingle flute solid carbide gundrills.

Hole straightness

Whipping or deection of the gundrill ute plays a decisive role in hole straightness and run out in the workpiece. Carbide tipped gundrills must be supported by a steady rest or whip guide every 40 diameters.For further information, refer to page 24 and 25.

1. Before using the drills make sure the machine has the necessary equipment to do proper deep hole drilling.The machine should have suitable safety guarding for protection from cutting chips and coolant for operator. Check with machine builder!

2. Improper use or handling of deep hole drilling tools can cause serious injuries, e.g. skin cuts from the cutting edge.

3. Deep hole drilling tools are not self centering and can be unbalanced. Therefore the drills must be guided during the start of the drilling cycle by means of a sufciently long drill bush or pilot hole (see detail ”Z” on below illustration). For information on the guide hole (pilot hole) see page 5.

4. The gundrill is fed into drill bush or pilot hole while non rotating or rotated slowly at < 50 RPM. Then the coolant and themachine spindle should get started.

5. After reaching the drilling depth switch off the coolant and retract with the spindle stopped or slowly rotatedat < 50 RPM.

6. Tool support: unsupported drill length should never exceed the dimensions as shown on table (6a). If the unsupported drilllength is exceeded the drill might cause injury.Do not exceed 40 times diameter unsupported (Type 110)!

Regrinding / Service

Regrinding of botek single flute gundrills

Gundrills must be reground with great care using a diamond grinding wheel. Drills with a diameter greater than 10 mm,in particular drills with inserted carbide cutting blade and guide pads should be wet ground when possible.

botek provides a customized regrinding service, and will be pleased to carry out this work for you.

We also supply special grinding machines and accessories which enable you to regrind single ute gundrills easily and quickly at your facility.

botek twin grinding wheels for pre- and finish-grinding have a proven record of performance.These grinding wheels allow our customers to economically regrind our gundrills.

Various grinding wheels are available from stock.

It is important that the carbide tip does not become overheated during grinding.Overheated carbide can cause thermal cracking and premature tool life.

Under no circumstances should the ground surface show any signs of discoloration.

Further grinding wheels on request.

Regrinding / Service

For detailed information, refer to brochure ‘botek Grinding Machines and Accessories’

Using botek grinding fixtures, single flute gundrills can bereground on any good tool

grinding machine.Depending on tool diameter,

botek grinding fixturesare available as Model ZS

(see illustration left) orModel PS (for solidcarbide gundrills).

For grinding small batches,we supply the botek MS-01

single station grindingmachine (with worktop).

You can easily install the abovementioned botek grinding fixtures

on this machine.

For highly efficient grinding of large batches of toolswith the same point geometry, we recommend

botek MS-12 multi-station grinding machine.

The machine is suitable fortool diameters from 1.850 to 12.000 mm and

tool lengths up to approx. 1.000 mm, and is available with either 2 spindles (MS-12) or 3 spindles

(MS-12/3) (standard version without lamp).

After you have set the fixture, you will obtain consistent andeconomical regrinding results easily and quickly with botek machines.

The following methods are available:

1. Measurement of the machine pump performance:

By means of a tool dummy a tool-independentcheck can be carried out – a big advantage.

2. Measurement with the tool:

The tool dummy is replaced by the actual drill.The pressure can be checked directly at the tool.

Quite often the set value at the pressure gauge is notreflecting the value that actually reaches the tool.

Numerous sources for errors such as leaking valve parts, faulty

rotating connectors or snapped hose lines are not visible on firstsight. Leading to a decreased coolant pressure, this could influencethe drilling result negatively.

The gauging-kit developed by botekmeasures the real pressure –directly at the spindle/tool(up to a max. of 160 bar).Taken measurements consider different coolant channel s

The botek grinding fixture PS was developed for re-sharpening single flute gundrills within a diameter

range from 0.5 - 6.0 mm. The fixture may be installed on a botek grinding machine MS-01 or a standard

tool grinding machine.

By changing the grinding stations,our standard nose grinds SA-0009, SA-0002 and SA-0227 can be

produced.The angles of the cutting edges are fixed, depending on which grinding stations are chosen.

Single flute gundrills are clamped into a tool holder for re-sharpening. Each tool holder is suitable for one

gundrill driver diameter of 10,12 or 12.7 mm. The tool holder is inserted into each grinding station and

pressed against the adjustable stop and passed across a rotating diamond wheel.The relief angles are

achieved by moving the grinding station to a second position.

Gundrills are clamped in the tool holder using a pre-setting fixture with microscope. A different tool holder

bushing may be ordered for each gundrill diameter.Tool holders are available in specific gundrill diameter

ranges and driver types. Please refer to the following page for further details.

Grinding fixture PS

When selecting the grinding fixture PS, the desired nose grind must be specified.

Clamping range

The botek grinding fixture ZS is designed for low volume production re-sharpening of single

flute gundrills.

The fixture may be installed on a botek grinding machine MS-01, or a standard tool grinding machine.The

desired angles are set on the grinding fixture using graduated scales.The gundrill is inserted into the clam-

ping unit and a vee-shaped jaw holds the gundrill securely in the flute.

Grinding Fixture ZS

When choosing a grinding fixture,please consider the required flute lengths and gundrill diameter range to

be sharpened.

Standard nose grinds for botek single flute drills

The nose grind geometry affects the following: chip formation, drilling tolerance, centerline deviation (drift)

and tool life.

Over the years, botek has successfully tested a number of different nose grinds for drilling various materials.

botek’s experience has formed the foundation for the development of our standard nose grind geometries.This

meets the requirements of most drilling applications.Deep-hole drilling of especially long chipping materials and

difficult to machine materials usually call for special nose grind geometries,and in some cases, made to order chip

breakers.

Regrinding instructions can be provided from case to case. If there is no other information given,botek single flute

drills will be reground as per nose grind SA-0001, SA-0002, SA-0003 and SA-0009 as shown below.

Cup wheel

For re-sharpening single flute gundrills within a diameter range from 0,5 to 2,0 mm a cup wheel

is most suitable.The gait of the wheel is chosen to keep an excellent grinding quality and

sufficient stock removal without overheating the tool.

Order No: 125 000 218

Double grinding wheel

The double grinding wheel is ideal for re-sharpening single flute gundrills up to 45 mm diameter.

The coarse grit of the outer wheel is for roughing the tool with high stock removal and minimum

heating of the tool. The fine grit of the inner grinding wheel provides optimum surface finish

with light stock removal.

Order No: 729 00 107

Remark: We recommend re-sharpening gundrill diameters greater than 32 mm on larger machines.

Deep hole dril l ing onmachining centres

1. Before using the drills make sure the machine has the necessary equipment to do proper deep hole drilling.The machine should have suitable safety guarding for protection from cutting chips and coolant for operator.Check with machine builder!

2. Improper use or handling of deep hole drilling tools can cause serious injuries, e. g. skin cuts from the cutting edge.

3. Deep hole drilling tools are not self centering and can be unbalanced.Therefore the drills must be guided duringthe start of the drilling cycle by means of a sufficiently long drill bush or pilot hole.

4. Tools support:unsupp orted drill length should never exceed the dimensions as shown on table (previous page).If the unsupported drill length is exceeded the drill might cause injury.Do not exceed 40 times diameter unsupported!

5. The gundrill is fed into drill bush or pilot hole while non rotating or rotated slowly at < 50 RPM.Then the coolant and the machine spindle should be started.

6. After reaching the drilling depth switch off the coolant and retract with the spindle stopped or slowly rotatedat < 50 RPM

7. Grinding of carbide produces dust (cobalt,etc.) that may be potentially hazardous.Use adequate ventilation andsafety glasses during grinding.

8. Consequences of not following our application notes No.1 – 7

Overview

Chip breaker

1. The chip breaker has a decisive part to play with the chipformation.

2. To obtain trouble-free chip flow along with optimum toollife, it is essential to aim for the most ideal chip formationpossible.

3. The chips should be broken just short enough to ensure thatthere is no chip congestion in the flute of the drill.

4. Excessively short, crushed chips place strain on the cuttingedges and lead to premature wear and will destroy thecutting edge.

5. For processing commonly used materials, indexable inserts areavailable from stock with chip breakers in accordance withmodel SP 1 or model SP 2.

Technical appendixRequirements for application / Dimensions for the guide hole

The characteristic of the single flute gundrilling process is that coolant is fed through the coolant hole in the tool and exits along

with the chips in the V-shaped groove (flute) on the drill tube from the drilled hole. The coolant also provides lubrication to the drillperiphery.

The gundrill is a single-edged tool without self-centering. When positioning the drill, the tool must be guided through a drill bush ora pilot hole.

The quality of the guide hole affects the drilling performance.

1. An efficient coolant and filtration system with a coolant filtration of 20 µm to 30 µm (the smaller the drill diameter, the betterthe coolant and filtration system should be).

2. Suitable coolant, i.e. deep hole drilling oil or emulsion (min. 10-12% concentration, with additives) has to be provided insufficient quantity and pressure. Minimum quantity lubrication (MQL) may be used under certain conditions.

3. Guidance with a drill bush (deep hole drilling machine) or a pilot hole (machining centre).

The dimensions specified in the table are guide values and comply with ISO tolerance field F7. ISO tolerance F8 is possible underspecific conditions. To avoid chipping of the cutting edge, a chamfered pilot hole (F) is recommended depending on machiningrequirements.

In application with deep hole drilling machine we recommend to use drill bush with F7 hole tolerance.

Technical appendix

Drilling quality

To achieve optimum drilling results when using deep hole drilling tools with indexable inserts and guide pads, various criteria

must be applied. In addition to tool design, key factors are machine design and construction, process techniques, pressurised andfiltered deep hole drilling coolant. Selection of proper cutting parameters is also a significant factor.


1. Material type

2. Diameter, tolerance and surface finish

3. Carbide grade and coating

4. Nose grind geometry

Hole straightness

Whipping or deection of the gundrill ute plays a decisive role in hole straightness and run out in the workpiece.

Carbide tipped gundrills must be supported by a steady rest or whip guide every 40 diameters.

For further information, refer to page 18.

Technical appendix

Drilling quality

Centerline deviation (drift)

Counter-rotation: The optimum results are achieved with a rotating tool and simultaneous workpiece counter-rotation: See „Z“.

Workpiece rotating: The next best technique involves the workpiece rotating with the gundrill non-rotating: See „Y“.

Tool rotating: See „X“.

In all applications tool drift is minimised by using a close fitting pilot bore or guide bushing during gundrilling.

Angular alignment of pilot bore with desired gundrill bore is imperative.

With a guide bushing, alignment and distance from the workpiece are also important.

Roundness

Hole roundness is a primary advantage of gundrilling over conventional twist drilling.

Hole roundness measurements as low as 10 µm are possible.

Application notes

1. Before using the drills make sure the machine has the necessary equipment to do proper deep hole drilling.

The machine should have suitable safety guarding for protection from cutting chips and coolant for operator. Check with machine builder!


3. Deep hole drilling tools are not self centering and can be unbalanced. Therefore the drills must be guided during the start ofthe drilling cycle by means of a sufficiently long drill bush or pilot hole (see detail „Z“ on below illustration). For informationon the guide hole (pilot hole) see page 15.

4. Tool support: Unsupported drill length should never exceed the dimensions as shown on table. If the unsupported drilllength is exceeded the drill might cause injury.

5. The gundrill is fed into the drill bush or pilot hole while non rotating or rotated slowly at < 50 RPM. Then the coolant and themachine spindle should be started.

6. After reaching the drilling depth switch off the coolant and retract with the spindle stopped or slowly rotating at < 50 RPM.

7. Grinding of carbide produces dust (cobalt, etc.) that may be potentially hazardous. Use adequate ventilation and safety glassesduring grinding.

8. Consequences of not following our application notes No. 1 - 7.

Quite often the set value at the pressure gauge is not reflecting the value that actually reaches the tool.Numerous sources for errors such as leaking valve parts, faulty rotating connectors or snapped hose linesare not visible on first sight. Leading to a decreased coolant pressure, this could influence the drillingresult negatively.

The gauging-kit developed by botek measures the real pressure –directly at the spindle/tool (up to a max. of 160 bar).Taken measurements consider different coolant channel sizes.

The characteristic of the 2-ute drilling process is that coolant is fed through the coolant holes in the tool and exits along with the

chips in the flutes from the drilled hole. The coolant also provides lubrication to the drill periphery. Conditions for successful deep hole drilling

1 An efficient coolant and filtration system with a filtration of 20 µm to 30 µm (the smaller the diameter, the better the coolantand filtration should be).

2. Suitable coolant, i. e. deep hole drilling oil or emulsion (min. 10-12 % concentration, with e. p. additives) has to be provided insufficient quantity and pressure. Minimum quantity lubrication (MQL) may be used under certain conditions.

3. Drill guiding through drill bush or pilot hole in the workpiece.

The 2-ute gundrill is not self centering. When positioning the drill, the tool must be guided through a drill bush or a pilot hole. The quality of the guide hole affects the drilling performance (tool life, centreline deviation, etc.).


For precise holes we recommend to use the ISO tolerance G6. The dimensions specified in the table are guide values.To avoid chipping to the cutting edge, a chamfered pilot hole (F) is recommended depending on the machining requirements.Please refer to application notes on page 18.

Solid carbide 2-flute drills

Type 123

Tool design

Drill and head shaft are manufactured from a single piece of carbide blank. The advantage of this tool is high process reliability andperformance. Longer tool life is possible due to reduced torsional vibrations and higher rigidity.

Nose grind geometry

The nose grind geometry affect the following, hole tolerance, chip formation, coolant pressure and flow, tool life, centreline deviation

and surface quality. Over the years, botek has successfully tested a number of different nose grinds for drilling various materials.botek‘s experience has formed the foundation for the development of our standard nose grind geometries. This meets the require-ments of most drilling applications. Drilling of especially long chipping materials and difficult to machine materials usually call forspecial nose grind geometries, and in some cases, made to order chip breakers, all available from botek.

Type 123

Please note:

- Guide values only.

- Coated drills may produce different chip formation (often longer chips).

- Use adequate feed rate to produce short but not compressed chips.

- High cutting efficiency is only possible if troublefree chip evacuation is guaranteed (see coolant diagram).

Please note:

- Optimum tool clamping (hydraulic chuck, shrink fit) ensure best results in surface quality and hole straightness.

- Reduced feed rate during interrupted cut, cross holes and angle entry or exit.

Technical informationType 120 / Type 122 / Type 125

Cutting speed and feed rate are dependent on tool length, coolant type and materials. In addition, the stability of the machine andworkpiece clamping. All figures specified are guide values.

Reliable chip removal is only assured if sufficient coolant is supplied to the tool. The diagrams show our recommendation for coolantpressure and quantity by drill diameter.

The ideal viscosity of deep-hole drilling oil should be 15 mm²/s (60 - 70 SUS) at 40°C for drilling diameters up to 18 mm.

When using emulsion, the specied pressures (p) may be reduced by up to ~ 20 %.

For all drill diameters filtering is required between 5 µm and 20 µm.

Drilling quality

To achieve optimum drilling results when using carbide tipped or solid carbide gundrills, various criteria must be applied. In additionto tool design, key factors are machine design and construction, process techniques, pressurized and filtered deep hole drillingcoolant. Selection of proper cutting parameters is also a significant factor.


- Material type


- Peripheral contour

- Carbide grade and coating


In addition to our rened manufacturing and technology for consistent product quality, our application and technical experience help you realize optimal solutions.

Drilling sequence:

1. Drilling pilot hole (dimensions see table page 5).

2. Feed gundrill into pilot hole while non rotating or rotating slowly (< 50 U / min).

3. Switch on the coolant.

4. Switch on spindle rotation and feed.

5. After reaching the drilling depth switch off coolant and spindle rotation.

6. Switch off coolant.

7. Retract tool (maximum rotation not exceeding 200 rev. / min. without support). Take care for safety information (see backside).

Application notes

1. Before using the drills make sure the machine has the necessary equipment to do proper deep hole drilling.

The machine should have suitable safety guarding for protection from cutting chips and coolant for operator. Check with machine builder!


3. Deep hole drilling tools are not self centering and can be unbalanced. Therefore the drills must be guided during the start ofthe drilling cycle by means of a sufficiently long drill bush or pilot hole.

4. Tool support: unsupported drill length should never exceed the dimensions as shown on table. If the unsupported drill length is exceeded the drill might cause injury.

Maximum unsupported drill length (L) between the steady rests or in a guide hole.

5. The gundrill is fed into a pilot hole while non rotating or rotated slowly at < 50 RPM (illustration). Then the coolant and themachine spindle should get started.

6. After reaching the drilling depth switch off the coolant and retract with the spindle stopped or slowly rotated at < 50 RPM.

7. Grinding of carbide produces dust (cobalt, etc.) that may be potentially hazardous. Use adequate ventilation and safety glassesduring grinding.

8. Consequences of not following our application notes No. 1 - 7.


If you have any questions, please do not hesitate to contact us. P: +49 7123 38 08-0.

Using botek gundrills other than directed may cause personal injury.

Tool breakage and unsupported gundrills can be extremely dangerous.

Please use with caution and care.
