Value Collection ESTW-40 Taper Wiper 40 Taper Cnc Fixture

Product Description

The VALUE COLLECTION ESTW-40 is a taper wiper designed for use with horizontal and vertical CNC tool tightening fixtures. It cleans the taper bore of the spindle or tool holder before tool changes, removing chips, coolant residue, and debris that cause runout and premature wear. The ESTW-40 is built for 40-taper tooling systems and measures 7.4016 inches overall length. It is a routine maintenance consumable used by CNC machinists and toolroom technicians to maintain spindle accuracy and extend tool holder life.

This taper wiper is suited for production and job-shop CNC machining environments running 40-taper spindles. It is used during tool change procedures on horizontal and vertical machining centers to ensure the taper interface is clean before seating a new tool holder. Keeping the taper clean is a standard step in maintaining tool change repeatability and avoiding spindle damage from contaminated contact surfaces.

Installation Notes

This wiper is installed and used by CNC machinists or toolroom technicians during standard tool change or maintenance procedures. Power down the spindle and confirm the machine is in a safe, locked-out state before accessing the spindle taper. Insert the wiper fully into the taper bore and rotate as needed to clear debris before seating the tool holder. Follow the machine manufacturer guidelines for tool change intervals and spindle maintenance frequency.
