Value Collection 204-3216 ER32 Collet 0.25 Inch

Product Description

The VALUE COLLECTION 204-3216 is an ER32 series collet designed for use in ER32-compatible collet chucks on milling machines, machining centers, and CNC lathes. It accepts a 0.25 inch (1/4 inch) round shank tooling and delivers a total indicator runout (TIR) of 0.0005 inches, making it suitable for precision tool holding applications where concentricity matters. Machinists and CNC operators rely on this collet to secure end mills, drills, reamers, and other straight-shank cutting tools during metal removal operations. The part weighs 0.375 pounds.

This collet is appropriate for job shop, production, and maintenance machining environments running ER32 collet chuck systems. It fits standard ER32 collet chucks used on vertical and horizontal machining centers, manual knee mills, and CNC turning centers equipped with live tooling. The 0.25 inch bore size is one of the most common shank diameters in general-purpose cutting tool inventories, making this collet a frequent replacement and stocking item in tool cribs.

Installation Notes

Installation should be performed by a qualified machinist familiar with collet chuck systems. Power down and de-energize the machine spindle before inserting or removing any collet. Seat the collet fully into the nut before threading onto the chuck body, and tighten the collet nut to the chuck manufacturer's specified torque using the appropriate spanner wrench. Inspect the collet for wear, cracking, or debris before each use, as damaged collets can result in tool pullout or reduced accuracy.
