The inside of the ER collet nut is intentionally designed like off-centering to help mount the ER collet much easier. It is in accordance with the requirements listed in ISO 15488:2003(E). If it is made symmetrical, the ER collet with the diameter larger than the inside size of the collet nut cannot be installed.
MT2 Shank Compatibility: Fits perfectly with manual milling machines equipped with Morse Taper 2 spindles for enhanced machining stability.
ER32 Collet Adaptability: Enables the use of a wide array of collet sizes from 0.08" to 0.787", broadening the scope of machining tasks.
Durable Tool Steel Construction: Made from high-grade tool steel, hardened and precision ground for extended tool life and consistent performance.
Exceptional Precision: Features a maximum Total Indicator Runout (TIR) of 0.0002" O.D to I.D, crucial for achieving superior machining accuracy.
High-Speed Operational Capability: Designed to perform optimally up to 8000 RPM, accommodating both high-speed and precision milling operations.
