Techniks 04624 ER25 Collet Wrench Steel Head

Product Description

The TECHNIKS 04624 is an ER25 collet wrench designed to tighten and loosen ER25 collet nuts on CNC machining centers, lathes, and milling machines. The wrench features a steel head for durability under repeated torque loads in production and job-shop environments. It is a hand tool used by machinists and tool-crib technicians during toolholder setup, presetting, and changeover operations. The steel head construction resists deformation at the collet nut engagement points, helping maintain proper contact and reducing the risk of rounding the nut over time.

This wrench is suited for use in machine shops, manufacturing facilities, and toolroom environments where ER25 collet chucks are in regular rotation. It is appropriate for both manual and semi-automated toolholder assembly benches. Machinists performing quick-change tooling setups or first-article preparation will find this a standard bench tool. It is sized specifically for the ER25 collet series and is not interchangeable with other ER collet sizes such as ER16, ER20, ER32, or ER40.

Key Features

• Steel head construction resists wear at the collet nut engagement surface
• Sized specifically for the ER25 collet series
• Used for tightening and loosening ER25 collet nuts during toolholder assembly
• Compact hand tool suitable for bench use in machine shop and toolroom settings

Compatibility

Designed for use with ER25 compatible collet series toolholders and collet nuts.

Installation Notes

Always power down and lock out the machine spindle before performing any toolholder or collet nut service. Use this wrench only with ER25 collet nuts - using a mismatched wrench can damage the nut and reduce clamping accuracy. Apply steady, controlled torque when seating or releasing the collet nut; avoid impact or pipe extensions on the wrench handle. Follow the toolholder manufacturer's recommended torque procedure for final clamping.
