Both large collapsibility and precise chucking achieved by the pull collet design.

Slim and compact

Slim and compact without the nut at the tip and minimize interference with work-piece and jig fixture.

Fewer collet types means easier collet management .

With their optimal collapsibility, these collets make it possible to reduce the number of collets you need by 90%, compared to our former products.

Highest guaranteed accuracies throughout entire chucking range (100% inspection).

Accuracy is guaranteed even using collapsibility.

Multiple coolant systems

The spindle-through feature can be used whether the cutting tool has oil holes or not.

Pre-balanced design (DTE type)

The collet holder is pre-balanced by previously designing the holder to be as axisymmetrical as possible. When used with the precision collet, it enables stable machining during highspeed machining.
