■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.)
