Chip formation

The nut design is a key factor to achieve the highest precision of a collet

  • A 45° trapezoidal thread offers less friction between alignment to the center when clamping a collet

  • Since the threads greatly influence accuracy, they are finished after heat treatment. Therefore, bad influence from clamping action is eliminated, which enhances clamping performance.
  • The nut incorporates a thrust bearing with steel balls that prevent stress to the collet and allows a smooth clamping force.

    Replaceable seal used in Perfect Seal


    Spare seal is recommended when coolant leaks due to damage of PS Ring.



    Highest runout as small as .00004" T.I.R. at the collet nose

    Since all collets are inspected, T.I.R. never changes, even when a collet clamps the smallest shank diameter.

    This Plug Screw A (option) prevents coolant leakage through retention knobs

    Bores on Form B are sealed with Plug Screw B.

    * Remove Plug Screws B (2 pcs.) from end face of flange.
    * Failure to use the Plug Screw "A" or other sealing method may result in coolant contamination of the spindle and lead to premature failure or accidents.
