ER & DA Toolholder Collets

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 col- lets feature a compression range of up to

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 and boring bars and special round shank end working tools. ERNC-Style Collets are sealed for coolant up to 1000 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

PAGE 14 ERTCSP Tap Collets ERTC Solid Floating 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. fit in the same tool holders which 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. 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.

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. 4
