Collet extension shank ER25 Mini S20 L100

Extension for ER25 Collet Chucks S20 L100 – increased reach and precision of machining

Index: 183.ER25.S20.L100

Industrial precision extension for ER25 collet chucks, designed to extend the working reach of tool holders on CNC machining centres and stationary milling machines. It enables machining in hard-to-reach places, narrow spaces, and during deep milling without the risk of collision between the main chuck and the workpiece. Made of hardened steel, it features high co-axiality, precision workmanship, and vibration damping during operation under heavy load.

Design advantages and technical properties:

• Increased machining reach: The slim cylindrical shank enables machining in deep recesses and hard-to-reach areas of the material.
• ER25 collet system: Compatibility with standard collets guarantees secure holding of the tool shank and reduces axial runout.
• Sturdy steel construction: The ground body ensures rotational stability, reducing vibrations and protecting the spindle bearings and cutting edges from premature wear.
• Mounting versatility: The cylindrical shank allows for efficient mounting in standard chucks and milling holders.

Intended use and applications:

The tool is designed for holding shank end mills in operations requiring significant reach on CNC machining centres and top- and bottom-spindle milling machines.
