Value Collection 204-3222 ER32 Collet 0.344 in

Product Description

The VALUE COLLECTION 204-3222 is an ER32 series collet designed for use in ER32-compatible collet chucks on milling machines, machining centers, and CNC lathes. This collet accepts a 0.344 inch (11/32 inch) workpiece or tool shank and delivers a total indicator runout (TIR) of 0.0005 inches, supporting accurate tool holding for precision machining operations. Machinists and toolroom technicians install this collet when tight concentricity tolerances are required in production or job-shop environments. Its ER32 taper geometry provides consistent clamping force and is a widely used standard across manual and CNC machine tool platforms.

This collet is suited for use in metalworking shops, fabrication facilities, and maintenance tool rooms. It fits any machine spindle or chuck that accepts the ER32 collet standard. Typical applications include holding end mills, drills, reamers, and round-shank tooling at 0.344 inch diameter. It is installed by machinists, tool and die makers, and CNC operators working with standard ER32 toolholding systems.

Key Features

• ER32 collet series for compatibility with ER32-standard chucks and tool holders
• 0.344 inch (11/32 inch) bore size for direct tool or workpiece engagement
• 0.0005 inch TIR for high-concentricity tool holding
• Single-piece collet construction standard to ER toolholding systems
• UNSPSC Code 27112800 classified under cutting and forming tools

Compatibility

Designed as a direct-fit replacement or supplemental collet for any ER32-standard collet chuck or toolholder accepting a 0.344 inch bore collet.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Before installing or removing the collet, power down the machine and confirm the spindle has come to a full stop. Seat the collet fully into the ER32 chuck nut before threading onto the holder to avoid cross-threading or collet damage. Use a proper ER32 collet wrench and chuck wrench for tightening — do not use improvised tools that may damage the nut or collet taper.
