Value Collection 204-3244 ER32 Collet 11/16 Inch

Product Description

The VALUE COLLECTION 204-3244 is an ER32 series collet designed for use in ER32-compatible collet chucks on milling machines, machining centers, lathes, and CNC equipment. This collet accepts tooling with a 0.6874 inch (11/16 inch) shank diameter and holds a total indicator runout (TIR) of 0.0005 inches, making it suitable for precision machining applications where concentricity and tool stability are critical. It is installed and serviced by machinists and CNC operators working in tool-and-die, production, and general machine shop environments.

This collet is suited for use in any standard ER32 collet chuck system in both manual and CNC machine tool applications. The ER32 series is one of the most widely used collet standards in machining, found in vertical and horizontal milling setups as well as turning and drilling operations. The 0.6874 inch bore accommodates common 11/16 inch diameter end mills, drills, reamers, and other round-shank tooling used in general and precision metalworking.

Compatibility

Designed to fit standard ER32 collet chuck systems used on CNC machining centers, manual mills, lathes, and drilling equipment that accept the ER32 collet series.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Before changing collets, ensure the machine spindle is fully stopped and the machine is powered down or placed in an E-stop state. Use the appropriate ER32 collet nut and chuck wrench to seat and torque the collet properly — do not over-tighten by hand or with improvised tools. Inspect the collet seating surface and collet chuck bore for chips or debris before installation to maintain rated TIR.
