Seco 00073563 ER32 Collet Chuck Spanner Wrench

Product Description

The SECO 00073563 is a spanner-style wrench designed for tightening and loosening ER32 collet chuck nuts on CNC machining centers, lathes, and milling machines. The spanner engages the nut slots directly, providing the mechanical advantage needed to achieve proper collet clamping force without damaging the nut face. This wrench is a dedicated toolroom and setup accessory used by machinists, tool crib technicians, and CNC operators during toolholder changes and collet maintenance. At 1 pound, it is a solid, hand-held tool suited for bench and machine-side use.

This wrench is sized specifically for the ER32 collet series, which is one of the most widely used collet standards in precision machining environments. It is appropriate for use in job shops, production facilities, and technical training environments where ER32 toolholders are in regular service. The wrench is sold individually and is a direct replacement or spare for worn or misplaced ER32 spanner wrenches in any toolroom inventory.

Installation Notes

This wrench is a hand tool used during toolholder setup and does not require installation. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before performing any toolholder or collet change. Use the spanner wrench only on the designated nut slots to avoid rounding or damaging the collet nut. Follow the toolholder manufacturer's recommended clamping procedure for proper collet seating.
