Accupro 777804 Spanner Collet Chuck Wrench

Product Description

The ACCUPRO 777804 is a spanner-style collet chuck wrench designed for tightening and loosening collet nuts on 1-inch milling chucks. This hand tool provides the mechanical advantage needed to properly secure collet assemblies during tooling changes on milling machines. The spanner design engages the spanner holes or slots on the collet nut face, delivering controlled torque without damaging the chuck body or nut surfaces. Machinists and toolroom technicians use it as part of routine tooling setup and changeover on milling equipment.

This wrench is intended for use with 1-inch milling chucks commonly found in vertical and horizontal milling machine setups in both job shop and production environments. It is a single-piece hand tool sold individually, suited for benchtop tooling stations and machine-side tool carts. It is typically used by machinists, tool and die makers, and CNC setup technicians who need a dedicated wrench matched to their chuck specification.

Installation Notes

Always power down and lock out the milling machine spindle before performing any tooling change. Ensure the collet and chuck body are clean and free of chips before seating the collet and tightening the nut. Use the wrench to achieve firm, snug engagement on the collet nut without applying impact force. Follow the machine tool manufacturer guidelines for proper collet seating procedures.
