Collet extension shank ER20 Mini S20 L160

Extension for ER20 Collet Chucks S20 L160 – increased reach and precision of machining

Index: 183.ER20.S20.L160

Industrial precision extension for ER20 collet chucks, designed to extend the working range of tool holders on CNC machining centres and stationary milling machines. It allows 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 manufacturing, and vibration dampening during operation under heavy load.

Design advantages and technical properties:

• Increased machining reach: The slim cylindrical shank allows cutting in deep pockets and hard-to-reach areas of the material.
• ER20 collet system: Compatibility with standard collets ensures secure holding of the tool shank and reduces axial runout.
• Sturdy steel construction: The ground body provides rotational stability, reducing vibrations and protecting spindle bearings and cutting edges from premature wear.
• Universal mounting: The cylindrical shank allows for efficient mounting in standard tool holders and milling fixtures.

Intended use and application range:

The tool is designed for mounting shank milling cutters in operations requiring significant reach on CNC machining centres and both overhead and underhead milling machines.
