A tool holder is any device that acts as an interchangeable interface between the machining center spindle and a cutting tool so that the efficiency of either is optimized.
In the spindle + holder + cutting tool
equation the tool holder is the link that has the most effect on overall concentricity, rigidity, and balance all of which have direct impact on the cost of the machining operation.

The problem with concentrically ground holders
In all side lock end mill adapters the internal bore of the tool holder must be larger than the
external diameter of the cutting tool
Internal bore tolerance .7503-.7500
External diameter tolerance .7499-.7496
-
The problem with concentrically ground holders
With standard concentrically ground holders once the set screw has been tightened down the cutting tool is pushed away from the centerline of the tool holder, automatically creating excessive TIR based on design alone. If our tool holder internal bore is at the mean of the limit .75015 and our cutting tool external shank is at the mean as well .74975 we would have .0004 mismatch between centerlines. Now rotate the assembly 360 degrees and you will show .0008 TIR.

The problem with concentrically ground holders
In Brineys Tru Position end mill adapters we actually grind the internal bore offset towards the locking screw by .0003 now when you clamp the screw down this actually pulls the cutting tool within .0001. If you rotate this assembly 360 degrees the max TIR is .0002 (at 4xs dia. to length ratio)

Tru Position eccentrically ground end mill bores
It has been written that for every .0001 of TIR your cutter life is decreased by as much as 10%. A standard side lock adapter has .0008 of TIR in the best of cases and Brineys Tru Position eccentric bore has .0002 TIR then tool life would be improved by up to 60% simply by switching your side lock adapters to Briney.

Total Tooling of Sabina, OH was interested in improving tool life on a standard profile milling operation, tools were having to be changed out every four hours. By only changing out their tool holder to Brineys eccentric bore end mill adapter tool life was increased to 6hrs before the tool had to be changed out, thats a 50% increase in tool life by simply changing out the end mill adapter to a Briney. Lets look at that in a mathematical context
So the price difference between the holders was $15 (calculates to Briney costing 23% more upfront) However the savings in tooling costs equaled $13.33 per day (33% decrease in daily cost) over a 30 day period this would equate to $399.90 or $4798.80 annually. So which holder really costs you less? Bottom line for $15 more you save $4k plus per year not a bad trade off.

General Spring Collet Specifications A spring collet is a device which is basically a modified length of pipe with the
capacity to expand and contract its end diameter depending upon the presence or absence of force applied by the outer collar. The general function and specifications are quite similar to the regular collet; however, the built-in spring mechanism between each third of the collets' end more readily resets the collet to its open position, preparing to receive the next tool end or cylindrical object. Given the added convenience of such a feature, it is easy to see why spring collets are more commonly found on premium tools.
Spring Collet Material and Usage Specifications Spring collets are used in low-diameter tool head gripping, milling and lathe turning
applications as quick change fittings for convenience when changing between tool bits. Spring collets are best suited to holding cylindrical objects. Spring collets are constructed of high durability hardened tool-grade steel. The metal of the collet spring is specifically engineered to withstand repeated use and maintain force resistance over extended use.
The Role of the Spring in a Spring Collet The spring in a spring collet is an ingenious improvement on the simpler design of a
standard collet. A spring collet fluidly opens as if of its own accord when the collar is unscrewed. The spring provides an outward opening force causing the diameter to expand, awaiting the next inserted cylinder.

Collet chucks DA (double angle) series collet
One of the first collet systems introduced
Has 2 angles to collapse collet Typical accuracy .001-.005 TIR 1/64 (.016) collapsibility
-
DA COLLETS...... A POPULAR SYSTEM DA Collets are recommended for drilling. DA Collets were originally designed to
clamp well on slightly uneven surfaces such as jobbers or taper length type drills. DA Collets are available in 1/64 increments and in .5mm increments for metric sizes. DA collets are also known in the industry as DA and VDA collets.
Recommended uses: DA collets are recommended for drilling only.
Accuracy: DA Collets are manufactured to within .0005 T.I.R. outer diameter to inner diameter. The length of parallelism between the two female contacting angles in the chuck controls the accuracy of the system and is held to within plus or minus .0002. The clamping nut floats slightly to allow the chuck to center the collet. Normal accuracy is approximately .001 T.I.R at the face of the collet chuck.
Care and use of DA Collets: The chuck, collet and nut must be thoroughly cleaned before assembling to maintain accuracy. A bench top ultrasonic cleaner will dislodge fine chips and debris or, a bottle type brush can be used for cleaning the inner diameter of the collet and a toothbrush style can be used to clean the exterior. Once assembled a normal machining environment will not affect the tool holding assembly.

Collet chucks TG (tremendous grip) series
First single angle collet system introduced
Typical accuracy .001-.002 TIR 1/64 (.016) collapsibility
-
TG COLLETS A QUALITY TOOLHOLDING SYSTEM TG achieves higher accuracy and greater gripping strength than DA and some other popular collet
systems. This system will perform well in applications up to 10,000 RPM. TG collets are also known in the industry as DF, BG, VDF, and PG collets.
Recommended uses: TG Collets are used for Milling, Drilling and Rigid Tapping. TG are available sealed for coolant through applications. TG collets. TG in 1/64 Increments or .5mm increments for metric sized tools.
Accuracy: TG Collets are within .0005 T.I.R.. The collet chucks are within .0002 T.I.R. from the cone to the collet seat bore. The nuts are designed to float to allow for centering of the collet. TG systems when properly cleaned and assembled can achieve approximately .001 T.I.R. on a cutting tool shank in the assembly at a checking point length of about 2-3 times the diameter of the cutting tool. The collapse range of the TG Collets is 1/64. As with all Collets it is recommended that the collet be used at the nominal or largest diameter. Sealed Collets do not have a collapse range and must be used at the exact size.
Care and use of TG: The chuck, collet and nut must be thoroughly cleaned before assembling to maintain accuracy. A bench top ultrasonic cleaner will dislodge fine chips and debris or, a bottle type brush can be used for cleaning the inner diameter of the collet and a toothbrush style can be used to clean the exterior. Once assembled a normal machining environment will not affect the tool holding assembly.
The TG Collets must be snapped into the Clamping Nut prior to installing onto the Collet Chuck. Collets can be removed from the clamping nut by holding the small end of the collet and tilting the collet angularly until it is removed from the nut. Do not attempt to remove the collet from the clamping nut by forcing the collet out from the front of the collet nut using a punch or screwdriver as this will damage the collet and clamping nut. For maximum accuracy and holding strength TG Collets must be tightened correctly.

Collet chucks BF (Brineyflex) series collet (same as Acraflex)
Uses 2 angles long angled surface collapses collet, short front angle helps keep collet nut forces centralized
Typical accuracy .001-.002 TIR 1/64 (.016) collapsibility
-
BF/AF COLLETS This highly accurate collet system was originated by Universal Engineering. Recommended uses: BF/AF Collets are recommended for drilling, milling and boring applications. BF/AF collets are also known in the industry as AF or RDF collets. Accuracy: BF/AF collets are available in 1/64 increments and limited metrics sizes. Collets are guaranteed to .0005 T.I.R. at 2 times the tool diameter, or a maximum one-inch from the face of the collet. Sizes .062 thru .172 are guaranteed .0010 at the nose Care and use of BF/AF: The chuck, collet and nut must be thoroughly cleaned before assembling to maintain accuracy. A bench top ultrasonic cleaner will dislodge fine chips and debris or, a bottle type brush can be used for cleaning the inner diameter of the collet and a toothbrush style can be used to clean the exterior. Once assembled a normal machining environment will not affect the toolholding assembly.

BR/ER COLLETSTHE BEST TOOLHOLDING COLLET SYSTEM The BR/ER System is the most versatile Toolholding System for any operation utilizing a round shank cutting tool in a machining or turning center. RD/ER
Collets are commonly known in the industry as ER, ESX, DR, BR, and VSAC Collets
Recommended uses: BR/ER collets can be used for drilling, milling, tapping, reaming and boring.
Accuracy: The BR/ER system is the only popular Toolholding systems in which all components (chuck, collets and clamping nut) are standardized by DIN 6499. The
accuracy of the BR/ER assembly is guaranteed to conform to the DIN 6499 Table. Most Toolholding Collet systems state the collet is .0005 or .001 T.I.R. but, that does not mean that this is the accuracy one will achieve on the cutting tool when mounted into the chuck. BR/ER systems are truly interchangeable. All manufacturers of this system should conform to the DIN6499 standard. This becomes important to users that may have toolholding systems from different
Toolholding System Manufacturers. As tools are taken out of the tool crib and reassembled for different jobs, if all the BR/ER system components are in good condition, and are from Quality Toolholding System Manufacturers, the collet and tool should achieve the DIN 6499 accuracy. While other Toolholding
systems may be interchangeable, none of the Toolholding Systems Manufacturers know the tolerances and specifications others are using for all of the components. Mixing components of Toolholding Systems other than BR/ER can have varying results.
Care and use of BR/ER:
The chuck, collet and nut must be thoroughly cleaned before assembling to maintain accuracy. A bench top ultrasonic cleaner will dislodge fine chips and debris or, a bottle type brush can be used for cleaning the inner diameter of the collet and a toothbrush style can be used to clean the exterior. Once
assembled a normal machining environment will not affect the toolholding assembly. The collet must be installed into the nut (see assembly instructions) before engagement with the collet chuck to ensure the collet is seated into the 30 degree concave angle of the nut. Putting the collet into the chuck and
then installing the nut will result in a condition that the eccentric ring of nut will engage only one side of the collet and produce poor results such as runout and drastically reduced holding strength.
Most BR/ER Collets are designed to collapse 1mm or .039. Never try to install a cutting tool with a larger shank than the maximum or nominal diameter of
the collet to expand the collet. For example: If the cutting tool shank is 4.2mm a 4-3mm is not suitable. A 4.5-3.5mm collet would be required. Sealed Collets for coolant through applications do not have a collapse range, and must be used at exact size. The radius of the collet must exactly match the radius
of the cutting tool shank in order to maintain a complete seal. If companies claim that they have sealed collets with a collapse range please keep in mind that if the radius does not match exactly coolant canals will be created by the mismatched radius of an improperly sized collet.
