Parlec 16ERENW ER16 Collet Chuck Spanner Wrench

Product Description

The PARLEC 16ERENW is a spanner-style collet chuck wrench designed for tightening and loosening ER16 collet nuts on CNC machining center toolholders. At 1 pound, it is a compact, purpose-built hand tool that provides the leverage needed to properly seat or release ER16 collets without damaging the nut or collet taper. Machinists and toolroom technicians rely on spanner wrenches like this to achieve correct collet preload and maintain accurate tool runout during setup and changeover operations.

This wrench is used in machine shop environments wherever ER16 collet chucks are part of the toolholding system. Typical applications include CNC milling, drilling, and tapping operations that use ER16-series collets. It is a standard toolroom item kept at the machine or in a setup cart for fast tool changes and routine collet maintenance.

Key Features

Compatibility

Designed for use with ER16 series collet chuck nuts. Fits standard ER16 collet chuck toolholders requiring a spanner-style wrench for collet nut engagement.

Installation Notes

This wrench is used by machinists and toolroom technicians during toolholder setup and collet changes. Always ensure the machine spindle is fully stopped and the controller is in a safe state before handling toolholders or performing collet changes. Use the wrench only on the collet nut it is sized for to avoid rounding or deforming the nut engagement points. Follow the toolholder manufacturer guidelines for proper collet seating procedure.
