Parlec ER40-0625 ER40 Collet 5/8 Inch

Product Description

The PARLEC ER40-0625 is an ER40 series collet designed for use in CNC machining centers, milling machines, and toolholding systems that accept the ER40 collet standard. It holds workpieces and cutting tools with a nominal capacity of 0.625 inches (5/8 inch) and a minimum collet capacity of 0.586 inches, giving machinists a practical clamping range for a variety of shank diameters. The overall length is 1.811 inches. This collet is installed by machinists and toolroom technicians in production and job-shop environments where precision toolholding is required.

This collet is suited for both production and maintenance machining applications where an ER40 collet chuck is already in use. It is appropriate for holding end mills, drills, reamers, and other round-shank tooling within its clamping range. The ER40 standard is common across a wide range of machine tool spindles and toolholding systems in both manual and CNC environments.

Compatibility

Designed for use in toolholding systems and collet chucks that accept the ER40 collet standard. Fits any machine tool spindle or chuck body manufactured to the ER40 specification.

Installation Notes

Installation is performed by a machinist or toolroom technician. Before changing collets, ensure the machine spindle is fully stopped and the machine is powered down or in a safe-stop state per shop safety procedures. Insert the collet into the collet nut before threading it onto the chuck body - do not tighten the nut onto the chuck without the collet seated. Use the appropriate collet nut spanner wrench and chuck wrench for final torque; do not use pipe extensions or makeshift tools on the nut.
