Accupro 775826 ER32 Collet Chuck Wrench

Product Description

The ACCUPRO 775826 is a dedicated spanner wrench designed for tightening and loosening ER32 collet nuts on CNC machining centers, manual mills, and lathes. It provides the mechanical advantage needed to properly seat and release ER32 collets without damaging the nut or collet body. At 7 inches in length and weighing 0.3 pounds, it delivers a comfortable one-handed grip for bench or machine-side use. Machinists, toolroom technicians, and CNC setup personnel rely on this wrench as a standard part of their collet tooling setup. Proper torque on the collet nut directly affects runout and tool retention, making a dedicated wrench like this a required item rather than an optional one.

This wrench is intended for use with ER32 series collet chucks in machine shop and production environments. It fits the standard ER32 collet nut profile and is used during tool changes, setup operations, and maintenance procedures on mills, lathes, and machining centers that accept ER32 toolholders. It is suitable for both high-volume production shops and job shop environments where ER32 tooling is standard.

Installation Notes

This wrench is used by machinists and CNC setup technicians during tooling changes and is not an installed component. Always ensure the machine spindle is at a full stop and the control is in a safe state before performing any tool change. Use the wrench to tighten the collet nut to the manufacturer-specified torque for the toolholder in use. Do not use extension bars or improvised handles on this wrench, as over-torquing can damage the collet nut threads or deform the collet.
