Collet extension shank ER25 Mini S20 L200

Extension for ER25 collets S20 L200 – increased reach and machining precision

Index: 183.ER25.S20.L200

Industrial precision extension for ER25 collets, designed to extend the working range of tool holders on CNC machining centres and stationary milling machines. It enables machining in hard-to-reach areas, narrow spaces, and during deep milling without the risk of the main holder colliding with the workpiece. Made of hardened steel, it features high co-linearity, precision construction, and vibration damping during operation under heavy load.

Design advantages and technical properties:

• Increased machining reach: The slender cylindrical shank allows for machining in deep pockets and hard-to-reach areas of the material.
• ER25 collet system: Compatibility with standard collets ensures a secure grip on the tool holder and reduces axial run-out.
• Rigid steel construction: The ground body provides rotational stability, reducing vibrations and protecting the spindle bearings and cutting edges from premature wear.
• Universal mounting: The cylindrical shank allows for easy mounting in standard holders and milling tool holders.

Intended use and application range:

The tool is intended for holding shank mills in operations requiring significant reach on CNC machining centres and both high-speed and low-speed milling machines.
