Capable of both spot drilling and chamfering

Spot drilling is not available with the 3-insert type.

Negative insert tip shape dramatically improves the life

As the nose radius on the insert forms negative land, it has high chipping resistance, and the tool life is significantly extended.

Effective for traverse chamfering!（Triple Insert Type）

3-insert type with maximum chamfering width of C9. Effectively reduces machining time.　
Spot drilling is not available with the 3-insert type.
