Value Collection ER25 Wrench Collet Chuck Spanner

Product Description

The VALUE COLLECTION ER25 WRENCH is a spanner-style collet chuck wrench designed for tightening and loosening ER25 series collet nuts on CNC machining centers, milling machines, and similar machine tool spindles. Measuring 6 inches in length, 2 inches in height, and 1 inch in width, it provides the leverage and fit needed to properly seat or release ER25 collets. Weighing 1 pound, the wrench is a single-piece tool sized specifically for the ER25 collet series. It is a standard accessory used by machinists and tool room technicians working with ER-style toolholding systems.

This wrench is used wherever ER25 collet chucks are installed or serviced. Typical applications include production machine shops, tool cribs, and maintenance environments where ER25 collet nuts must be torqued to specification during tool changes. The spanner design engages the collet nut directly, allowing controlled tightening without damaging the nut face. It is sold as a single unit and is appropriate for both bench use and at-machine tool changes.

Installation Notes

Power down and lock out the machine spindle before changing or seating collets. Use the wrench to engage the collet nut flats squarely to avoid slipping or rounding the nut. Follow the machine tool manufacturer's torque specifications for the ER25 collet nut, as over-tightening can damage the collet or chuck body. This tool is typically used by machinists and CNC setup technicians in accordance with shop safety procedures.
