Parlec ERS25-0472 ER25 Collet 12mm

Product Description

The PARLEC ERS25-0472 is an ER25 series collet designed for use in CNC machining centers, milling machines, and toolholding systems that accept ER25 collet chucks. It holds a 12mm tool shank with a clamping pressure rating of 1800, providing secure grip during cutting operations. The overall length is 1.338 inches with an overall diameter of 1.023 inches. Machinists and toolroom technicians rely on ER-style collets like this one for their wide clamping range, concentricity, and compatibility with standard collet chucks across multiple machine platforms.

This collet is suited for precision tool clamping in production and job-shop environments. It is appropriate for use in vertical and horizontal machining centers, drill-tap centers, and any spindle setup configured for ER25 collet chucks. The 12mm bore makes it a direct fit for 12mm shank cutting tools including end mills, drills, reamers, and taps. Typical installation is performed by a machinist or tool crib technician during tooling setup or changeover.

Installation Notes

Installation is performed by a machinist using a standard ER25 collet chuck and appropriate spanner wrench. Always ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before changing tooling. Insert the collet into the chuck nut before placing the tool shank, then thread the nut onto the chuck body and torque to the chuck manufacturer's specification. Inspect the collet for wear, chips, or deformation before each use.
