A bit close to the dreamOne hole, one bit. That´s the dream of every core driller who´s ever had to lift a heavy drillstring out of a deep hole to change a worn out bit.

But it helps to know that Atlas Copco is determined to make the dream come true. Take the new Golden JET bit for example. With a 16 mm high matrix it outlives all other diamond core drilling bits on the market. That means more time in the hole, less manual work and reduced costs.

Golden JET technology

With Golden JET bits you will boost your productiv-ity and take another step closer to the dream. One hole, one bit.

Golden JET bits are developed and manufactured by Atlas Copco within the Super Cutter range.

Golden JET bits

One hole, one bitAtlas Copco has launched a new range of long life wire line bits within the Craelius Super Cutter series. The Golden JET bit is the result of Atlas Copco´s commitment to develop unique products which improve our customers competitiveness.

Higher crown impregnation will logically lead to longer life. The JET design from Craelius diamond bits is a patented in-novative solution with increased impregnation height of the crown, to give extended bit life.

The Golden JET bits reflect our ambition to develop products to improve our customers cost effiency. Each meter we prolong the core production instead of wasting time and money on rod handling, is added value for the customer. We are not there yet – but we are getting closer to ’’One hole, one bit’’.

Production instead of rod handling

JET bit characteristicsnExtremely long life nWide range of rock formations nHigh penetration rates

Our unique solution, with increased impregnation height (currently 16 mm), results in an extremely stable crown.

By reducing the number of waterways, we created wider seg-ments and larger base for stronger adhesion to the bit body. To maintain optimal cooling and cutting transportation, the segments are designed with slots in both outside and inside.

This unique, protected solution gives a long bit life combined with high penetration rate. A combination of the JET design and the range of matrices from the Super Cutter series will outperform any other bit on the market.

SC2 Extremely abrasive, highly fractured.

Impregnated diamond drill bits are designed to perform as grinders. Diamonds are embedded in an infiltred or sintered matrix. The matrix erodes away at the same rate as the dia-monds become worn and rounded. Thus new sharp diamonds are exposed to continue cutting through the rock.

The combination of diamonds and matrix determine the per-formance of an impregnated bit. The simultaneous erosion of the matrix and the diamonds makes the bit self sharpening.

The ideal combination of optimal penetration rate and wear resistance matched to achieve the ultimate in drilling economy.

In most geological formations, impregnated bits are more economical to use than surface set bits as they provide ad-ditional benefits:

n Greater resistance to wear in most formations, particularly in fissured and fractured formations.

n Less sensitive to abuse, rough handling and improper use.

DiamondsOnly synthetic diamonds, except for gauge stones, are used in the manufacture of Atlas Copco impregnated bits. The constancy of shape, granular size, and strength make syn-thetic diamonds better than natural stones.

The diamonds are carefully selected by quality and size for the application. Through advanced manufacturing technology an extensive range of drilling requirements can be satisfied.

Continuous control of the processes at each step in the manu-facturing ensures that all bits are of identical quality. This consistent high quality means more drill metres per bit.

Crown heightStandard impregnated drill bits are available with different matrix heights:

n Low (2):6.5 mm, Conventional bits n Standard (3):9.5 mm, Conventional bits and WL bits n Extra high (4):12.5 mm, Wire line bits n Super (5):16.0 mm, Wire line bits

Low and standard height is used for conventional bits where bit life does not effect the number of round trips and when large wear of the bit diameter is anticipated (meaning that extra high matrix cannot be fully utilized).

For wire line bits, Extra or Super matrix height is generally recommended.

ProfilesMost impregnated bits have W-profile.

Surface set bitsAtlas Copco surface set bits are manufactured to the highest standards in the industry for the ultimate in drilling perform-ance.

Atlas Copco surface set bits have proven to have a high penetration rate, long service life, and best adaptability to changing formations. The diamonds in these bits are ar-ranged in patterns developed from many years of practical field experience. The patterns vary according to the size of the stones used.

The patterns are important for the service life and

penetration rate of the bit.

The diamonds used are imbedded in a hard matrix with high resistance to erosion.

MatrixSurface set bits are manufactured using a universal hard type of matrix for all formations.

Semi-round

Multi-step

Two wide step (face discharge)

Concave profile (Non-coring)

Diamond qualityThe standard range of natural diamonds for surface set bits is chosen in a special allround grade with special quality. The quality includes selected and processed diamonds with a highly polished surface. These stones have a high impact resistance and may be considered as an universal type. Rec-ommended for soft to medium hard formations.

Diamond sizes (spc – stones per carat)As a general rule; the softer formation, the larger the dia-monds used i.e. 20 to 25 spc. In hard formation, smaller diamonds 30 to 50 spc are typical.

Atlas Copco standard diamond sizes are: 20/25 and 30/35 spc 1 carat = Diamond weight of 0.2 g Diamond content is measured in carat (CRT).

Other diamond qualities and sizes on request.

ProfilesSurface set drill bits are available in different profiles to obtain optimal drilling performance.

Standard profiles for surface set core bits:

n Semi-round n Multi-step n Two wide step (face discharge) n Surface set n Non-coring bits with concave profile.

9

Shells and casingReaming shellsReaming shells are placed behind the drill bit on the core barrel to maintain the correct hole diameter and stabilize the core barrel.

A reaming shell has to be replaced when its diameter be-comes less than the diameter of the new bit. In this way only the very last part of the hole has to be reamed when a new bit is inserted. A reaming shell also helps to stabilize the core barrel. Reaming shells are available for all types of core bar-rels and drill bits.

Surface set reaming shellsStandard Atlas Copco surface set reaming shell set with specially selected diamonds and PDC pins. Well designed waterways, reinforced with PDC pins, facilitate effective flushing and contribute to long service life and good drilling economy for both reaming shells and drill bits.

Reaming shells are avialable in different designs:

n 10" Double ring reaming shell available only for BQ, NQ, HQ (need inner tube adjustment).

n FH special heavy duty design for long life with extra stabilization.

n STD (Standard design).

Casing shoesAtlas Copco manufactures a comprehensive range of dia-mond and tungsten carbide (Corborit) casing shoes for stand-ard drilling or positioning casing tubes into drill holes.

Casing shoes have cutting segments on the front and exterior, while the interior is smooth. The inner diameter of the casing shoe is sufficiently large to permit free passage of drill bits and core barrels in corresponding sizes.

n Impregnated casing shoe bits are manufactured with very hard matrix.

Tungsten Carbide (TC) bitsCarbide bits are normally used for coring in softer rock for-mations, overburden drilling, and cleaning of drill holes.

Atlas Copco manufactures two different types of tungsten carbide bits:

n TC bits with octagonal inserts nTC CORBORIT® bits

TC bits with octagonal insertsThese bits have octagonal tungsten carbide inserts what are ground at an angle of 10° to form the cutting edges. The quality of the tungsten carbide chosen has been specially de-veloped for rotary drilling to give high wear resistance. The carbide inserts can be reground.

TC Corborit® bits Corborit is another type of tungsten carbide bits manufac-tured of crushed carbide chips with a granular size of 2-5 mm, mixed with a special alloy.

Corborit bits have considerably more cutting edges than standard TC bits and are recommended in medium to me-dium hard sedimentary formations.

Corborit bits cause less vibration and offer better core recov-ery than standard TC bits.

All TC bits can be used in clean-out operations, e.g. for the removal of steel fragments from a drill hole.

TC bits

A range of bits designed especially for soil investigations and geotechnical drilling, but also suitable in some applications for mineral exploration.

Drilling parametersDrilling recommendationsTo select a suitable diamond bit for a given situation, basic information is needed:

n Geology n Type and size of core barrel n Flushing media

The final performance with selected bit depends on following parameters controlled by the operator:

n WOB – weight on bit n ROP – rate of penetration n RPM – revolution per minute n RPI/RPC – revolution per inch/cm n Flushing

Craelius impregnated diamond bits are supplied with recom-mended drilling parameters for best performance.

Sometimes an impregnated drill bit become blunt. Reason could be, difficult drilling conditions, hard formation, wrong drilling parameters, wrong bit type etc.

To sharpen an impregnated bit is a delicate process. If sharp-ening is not correct done, you will loose matrix and bit life. Momentarily increase the WOB by approximately 15-25%, at the same time, slowly reduce water flow to a level not less than what is indicated on the bit sticker. When the bit begins to sharpen, noticed by increase in drill system pressure and lower rotation speed, reduce the WOB and increase water flow to normal value.

Weight on bitWeight on bit (WOB) is not an operation parameter, the value is a result to maintain a constant penetration rate (ROP). Di-amec APC drill adjust WOB automatically for a preset ROP. The value of WOB for a chosen ROP indicates the actual drilling condition. Too high WOB value might cause problem such as:

n Excessive wear on bit n Hole deviation n Damage or wear on core barrel and rods

Please note!Recommended max WOB in the bit sticker is max allowed value to avoid damage. Temporary high WOB may be ap-plied to sharpen the bit. Too low WOB will polish the bit and it will loose its self-sharpening ability.

Penetration ratePenetration rate (ROP) is a very important drilling parameter especially for impregnated bits. The value should be kept constant and set as high as possible. High ROP keeps the bit sharp and return best performance.ROP depends on follow-ing conditions:

n Bit type and size n Capacity of core drill n Formation n Hole depth n Hole deviation n Flushing

Revolution per minuteImpregnated bits should generally be used with high revolu-tion per minute (RPM). Depending on bit diameter, rock condition and machine capacity.

Peripherical speed 2-5 m/s is recommended for impregnated bits. For surface set diamond bits peripherical speed 1-3m/s is recommended.

The RPM diagram gives a rough recommendation for RPM-related to bit type and hole diameter.

Example: A 76 mm diameter hole is to be drilled, the drill rod diameter is 53 mm and the desired flushing water velocity is 40 cm/s. Find the line for the 76 mm hole/53 mm drill rod; then find the velocity 40 cm/s on the curve’s X-axis. Follow the line 76/50 until it bisects the 40 cm/s line, then follow a horizontal line to the left line and read off the water volume = 63 l/min.

Drilling parametersFlushingParticularly for impregnated bits, bit performance is strongly dependent on water flushing. The flushing has three pur-poses: cooling the bit, lubricating the bit and drill string and to lift up the cuttings. Some bit types need a lot of water to perform well, others do not.

For most bit types a reduced amount of water sharpens the bit and reduces bit life, while a lot of water can polish the bit but increase the bit life. This is most valid in hard and polish-ing rock.

Suitable amount of water for each bit type is stated on the sticker for drilling parameters.

The required cutting volume to lift up the cuttings, depends on hole diameter and drill rod size. Required water volume can be calculated in the diagram below.

Always use the higher volume of the values in the dia-gram and recommended on the bit sticker. It is highly recommended to use an accurate flow meter.

Revolution per rate of penetrationRevolution per inch (RPI) or revolution per centimetre (RPC) of advance has been developed as an index to main-tain correct relationship between RPM and ROP.

Today Atlas Copco bits are design to perform with much higher ROP than the index originally was based on. The index should be considered as a starting point.

Index recommendation: RPI 200-250 (RPC 80-100) For recommended RPM 1200 you can expect ROP 6" (15cm) per minute

ROP = RPM/RPI = 1200/200 = 6 (inch/min) ROP = RPM/RPC = 1200/80 = 15 (cm/min)

Please note!Higher ROP Higher RPM Higher flow rate

Super Cutter (SC) range

nLong life, free cutting Extremely high impregnation, skilled engineering and unique production methods combined with high quality components.

n Wide range of applications Just a few matrices cover all rock formations.

n Fast and efficient penetration Unique matrix alloy design, allows worn diamonds to be replaced instantly by new diamonds.

Use recommended drilling parameters and the Super Cut-ter bit will give optimal performance provided the matrix selected is suitable for the actual rock formation.
