4 Overview: ER and DA Toolholder Collets ER-Style pages 0- Single- and double-angle collets feature a multi-slot design to provide maximum gripping force for efficient "push-back" control. This control helps prolong tool life which reduces machine downtime to produce more pieces-per-hour. All locating surfaces are precision ground to assure extremely close tolerances. Most of these collets feature a compression range of up to /64" (.68mm). Refer to the chart on page 2 for concentricity specifications. ERNC-Style page 2 ER-Style Single-Angle Collets Standard ER-Style Collets are used on Swiss-type lathes and in tool holders for mills and CNC lathes. They are used to grip drills, taps, reamers, end mills, boring bars and special round shank end-working tools. ERTCSP Tap page ERNC-Style Collets are sealed for coolant use of up to 000 psi. Exact sizes are available in metric, decimal inch and fractional inch. This series collet has fewer slots, resulting in less flexibility. ER-Style Single-Angle Tapping Collets ERTCSP Tap Collets are designed to be used in a floating tap holder. They are multi-split with a square hole in the back of the collet to keep the tap from slipping in the collet. ERQC Tap page 4 ERTC Tap page ERQC Quick-Change Solid Floating Tap Collets have a Bilz-style quick-change feature, eliminating the need to remove the collet to change taps. There is a square in the collet assembly to keep the tap from turning in the collet. This system fits in the same tool holders that use ER-style collets. Each collet is made for a specific tap shank size. The collet has a floating spindle, eliminating the need for a special floating tap holder. ERTC Solid Floating Tap Collets fit in the same tool holders that use the ER-style collets. Each collet is made for a specific tap shank size. The collet has a floating spindle, eliminating the need for a floating tap holder. The tap is held in the collet with set screws which grip on the square of the tap. DA-Style Double-Angle Toolholder Collets The Double-Angle Collet is noted for its parallel gripping capability due to the two angles and the opposed split configuration. This places the parallel bearing on the tool shank, as well as the full diameter of the tool. DA-Style pages

6 Overview: Tap Collets and Holders Hardinge TT Floating Tap Holder Collets TT Tap Holder Collets are used exclusively in the Hardinge TT Tap Holders 8" and 4" round shanks. Each collet is made for a specific tap size. A square broached hole TT Floating page securely holds the shank of the tap, eliminating tap slippage and misalignment. TT- 8 & - 4 Collet-Type Releasing Tap Holder TT Holder page The Collet-Type Releasing Tap Holder is used to provide thread length control on either right- or left-hand taps by switching a lever inside the body of the tap holder. The tap holder mounts directly into a round shank tool holder. TT-style tap holder collets are used for accurate holding and centering of taps. To provide a positive drive for the taps, the collets have a square slot in the back to accommodate the square on the tap shank and a notch in the back bearing of the collet that fits over a hardened pin in the bottom of the holder. GK Self-Feeding, Length-Control Tap Holder GK Holder page 4 The Self-Feeding (Pafix) Tap Holder provides automatic thread length control. The tap holder eliminates the need to match feed rate to thread pitch, minimizing tool breakage. The holder has a 8" shank diameter. Thread length is controlled internally with an adjusting ring in.0" (.2 mm) increments. A driver is used in the holder to accommodate the square of the tap shank, providing a positive drive. A collet is used to centralize and hold the tap in the holder. "Cool Stop" Coolant Seals Maximize coolant flow through your drills with the "Cool Stop" system. "Cool Stop" Seals are designed to seal around the shank of the drill and ID of the ER and TG holders. The gauge length of the holder does not change. The collet stays flush with the cap because the "Cool Stop" seal locates at the back of the collet. Each "Cool Stop" has a range from rated size down to.020" (.0 mm), resulting in a small seal inventory for each collet style. You can keep the coolant running through the drill (rather than out the collet) at pressures up to 00 psi. page 6 6

7 S Overview: Quick-Change Tap Collets and Holders Quick-Change Tap Collets are used throughout the industry for mounting into Bilz-style and other popular tapping holders. Many taper-flange milling machine tap holders use these collets. The quick-change feature allows changing the tap without removing the collet from its holder. This feature ensures precise length control from one tap to another of the same length. Quick-Change Style Straight- Tap Collets QC Tap page The Quick-Change Tap Collet is a quick-releasing style. The collet does not have to be removed from the holder to change the tap. The nose piece pushes in, releasing the tap while no wrenches are required. The Quick-Change collet can only be used in holders specifically designed for it. Torque-Release Quick-Change Straight- Tap Collets The Torque-Release Quick-Change Tap Collet unit allows the collet to release at a predetermined torque. This unit can only be used in tension/compression Bilz-style tap holders, specifically designed for these straight-shank tap collets. QC Torque Tap page 6 Tool Holder for Quick-Change Straight- Tap Collets The Straight- Tool Holder is used with Quick-Change style straight-shank tap collets. It can be mounted in round shank tool holders with either 4" or " bores. The holder can be used on CNC lathes and milling machines. QC Tap Holder page

Metric tap threads are consistent throughout the world; unfortunately the shanks are not, as you can see by the chart shown above. Because of the number of imported taps on the market, use a micrometer and check the actual size of the tap shank. Look it up on the chart and then order your tap collet accordingly.

47 ? Frequently Asked Questions "I m using a small diameter split drill bushing and I can t seem to get the drill parallel to the centerline of the spindle. Why?" A common cause for this problem is locking the second set screw on the bushing. The holes for small diameter drills do not extend the full length of the bushing. The back end of the bushing usually has a large internal chamfer or a counterbore. This cleared area is under the second lock screw. When you tighten this screw, the bushing may distort, shifting the drill s position. There may be line contact on which the drill will pivot. The solution is to use the front locking screw only. A second cause is that the bushing is too short. The first set screw is locking on the back of the bushing, causing it to collapse instead of gripping the shank of the tool. "I am trying to drill a very accurate hole using a DA-style collet system without any success. Any suggestions?" Extremely accurate drilling requires a very good holder and collet. With the considerable flexibility of the DA, TG and ER collets, we tend to forget the cardinal rule for collets the bore of the collet should be the exact size of the diameter being gripped for the best TIR and gripping force. Therefore, for extremely accurate drilling, the collet bore should be the same size as the shank of the drill. Second, if you have a choice of holders, it is best to use the ER collet holder over the DA collet holder. The DA holder is a double-angle holder with a closing angle on the front and back of the collet. The theory is that the collet will close parallel to the centerline of the holder. Unfortunately, it is very difficult to manufacture a holder and collet that accurately mate. For standard drilling tolerances, this usually is not a problem, but can be when doing extremely close tolerance drilling. The ER is considered a single-angle collet because the major closing angle is long and shallow. This results in better concentricity than the double-angle system. The TG collet system is better than the ER system because it has an even shallower closing angle. Unfortunately, this system is usually for larger shanks and most holders that use these collets are for vertical machining centers. For extremely accurate drilling, the bore of the collet should be the exact size of the shank of the drill. "I ve tried rigid tapping using standard ER collets in my non-floating holders and I m breaking taps. Why is this happening and is there a reasonably-priced solution?" Taps may be breaking because your machine tool may not be designed for rigid tapping, you did not buy that option, or there is a small error between the spindle reversal and slide reversal. These are machine tool problems that HARDINGE.com you can work around without disassembling the machine. Use a floating tap collet such as the ERQC or the ERTC. These collets fit in the standard rigid holder and will float longitudinally. If you want to continue to use your current collets, floating tap holders are available. These holders are longer than the standard holders and more expensive than the floating tap collets. "The TIR of the drill being held in my ER collet is excessive. What TIR can I expect from a standard ER collet?" Quick fix if you are using a ball bearing cap on your ER holder, change it to a one-piece cap. The ball bearing cap allows you to use more torque when gripping solid floating tap collets, but when used for drilling, the TIR is not as accurate as the one-piece cap. All of our ER collets are made to the DIN 64 specification. Refer to page 2 for the acceptable TIR for your collet. When checking the collet and holder, use a certified gauge plug. First, indicate the seat of the holder, then assemble collet and gauge plug and indicate the plug at the "L" dimension. Make corrections for holder seat runout (the most accurate check is to use a coordinate measuring system most indicators do not give a true reading when rotating 60 from the lathe spindle). If this checks out within specifications, check the gauge pin at the actual drill length, which may be longer than the "L" dimension. If the TIR at this point is too great, you will have to acquire a higher precision collet such as the ERNC. If you re using a metric bushing to hold a fractional drill, a more reasonable solution would be to acquire an inch series collet for the exact shank of your drill. "I am using an ER Collet in a high-speed spindle and am getting vibration that I don t get with my other holders. What s wrong?" You re probably using a standard one-piece cap. Acquire a one-piece cap that has a ring to hold the collet instead of the standard cap that has an eccentric slot. The eccentricity of the groove will cause an out-of-balance condition at high rpm. If this does not eliminate the vibration, the complete assembly will have to be precision balanced in relation to the RPM you re running. Hardinge Inc Toolholder Collets, Bushings & Tool Holders 4
