The ER32M tap collet with internal square drive is designed for rigid synchronized tapping operations on CNC machining centers, CNC lathes and machine tools equipped with ER collet chucks compliant with DIN ISO 15488 (DIN 6499).

This collet system ensures reliable torque transmission during threading operations, preventing tap slippage and maintaining maximum process stability even in demanding production environments.

The main feature of the ERC32M collet is the internal square drive, which allows direct engagement with the square shank of the tap. This configuration ensures that the torque generated during the tapping process is transmitted mechanically rather than relying solely on radial clamping force.

As a result, the system provides improved operational safety and increases both tool life and collet durability.

These collets are designed for use with standard taps DIN 371, DIN 374 and DIN 376, which are widely used in industrial threading applications. The collet clamps only the nominal tap shank diameter with h8 tolerance, ensuring precise centering and stable clamping.

The ERC32M series covers a clamping range from 3.5 mm up to 20 mm, allowing compatibility with a wide range of tapping tools and machining applications.

The elastic structure typical of ER collets provides uniform clamping along the entire tool shank, contributing to high rotational accuracy and reduced vibration during machining.

ERC32M tap collets must be used with ER nuts featuring an eccentric extraction system, which allows correct mounting and removal of the collet from the tool holder.

These collets are specifically designed for rigid tapping applications without axial compensation, where spindle rotation and machine feed are synchronized to generate the thread accurately.

Due to their reliability and precision, ER32M tap collets are widely used in industrial production, automotive manufacturing, precision machining, mold manufacturing, maintenance operations and CNC machining processes.

The use of high-quality materials and compliance with international standards ensures consistent performance and long operational life.
