Accupro 777806 Spanner Collet Chuck Wrench 1-1/4 in

Product Description

The ACCUPRO 777806 is a spanner-style collet chuck wrench designed for tightening and loosening collet nuts on 1-1/4 inch milling chucks. It provides the controlled torque needed to secure collet chucks without damaging the spindle or collet nut faces. This type of wrench is a standard toolroom accessory used during tool changes on vertical and horizontal milling machines. Machinists and tool crib technicians use it to ensure proper collet seating before cuts, keeping runout within acceptable limits and preventing tool pullout under load.

This wrench is suited for use in machine shops, production environments, and toolroom settings where 1-1/4 inch milling chucks are in regular service. It is a bench-side or machine-side tool used during routine tool changes and setup operations. Any application requiring reliable collet nut engagement on a 1-1/4 inch chuck diameter will benefit from a properly fitted spanner wrench rather than improvised alternatives that can damage nut faces.

Installation Notes

This wrench is installed and used by machinists or toolroom personnel during milling machine setup. Before changing tooling, disengage the spindle drive and confirm the machine is in a safe, non-operational state. Use the spanner wrench only on the intended collet nut style and size to avoid slipping or rounding the nut. Do not use extension handles or additional leverage beyond what the wrench is designed to provide, as over-torquing can distort the collet or chuck body.
