The chamfer angle is available as a 90°or 60°. Simultaneous centering and chamfering with one tool! Chamfering and groove ③ processing are also possible! ●Unlike a normal center hole drill, there is no drill part with a Point Drill, so the problems with breakage of the drill portion is eliminated. ●Simultaneous combining the positioning and chamfering are possible. It can also be used as a multi- ④ function tool for groove machining. ●High precision machining can be achieved with the two stage point shape.
