Rego-fix 7111.50000 ER50 Collet Chuck Spanner Wrench

Product Description

The REGO-FIX 7111.50000 is a spanner-style collet chuck wrench designed for use with ER50 collet systems and ER spanner nuts. This tool provides the mechanical advantage needed to properly seat and release ER50 collets in compatible toolholders. It is a single-purpose hand tool used during setup and changeover on CNC machining centers, lathes, and milling machines. Weighing 1.73 pounds, it is a solid, purpose-built wrench suited for production shop environments. Machinists and toolroom technicians rely on the correct spanner wrench to achieve consistent collet clamping without damaging the nut or collet body.

This wrench is intended for use in machine shops and manufacturing environments where ER50 toolholding systems are in regular service. The ER50 collet series accommodates large-diameter tooling, making it common on heavy-duty milling and turning centers. This spanner wrench is the appropriate tightening and loosening tool for setups involving ER50 collets and their associated spanner nuts. It suits both production machinists performing frequent tool changes and toolroom staff managing presetter workflows.

Installation Notes

This tool is installed and used by machinists and toolroom technicians during collet and toolholder setup. Always ensure the spindle or toolholder is secured and machine power is off or the spindle is locked before tightening or loosening collet nuts. Use only the correct spanner wrench for the collet series to avoid rounding the nut or damaging the collet. Do not use extensions or additional leverage beyond the wrench handle to avoid over-torquing the collet nut.
