Collet extension shank ER25 Mini S20 L160

Extension for ER25 collets S20 L160 – increased reach and machining precision

Index: 183.ER25.S20.L160

Industrial precision extension for ER25 collets, designed to extend the working range of tool holders on CNC machining centres and stationary milling machines. It allows for machining in hard-to-reach places, narrow spaces, and during deep milling without the risk of collision between the main holder and the workpiece. Made of hardened steel, it features high coaxiality, precision workmanship, and vibration dampening during operation under heavy load.

Structural advantages and technical properties:

• Increased machining range: The slim cylindrical shank allows for machining in deep sockets and hard-to-reach areas of the material.
• ER25 collet system: Compatibility with standard collets ensures a secure grip on the tool shank and reduces axial runout.
• 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 efficient mounting in standard holders and milling chucks.

Intended use and scope of application:

The tool is designed for mounting shank mills in operations requiring significant reach on CNC machining centres and overhead and below spindle milling machines.
