POINT DRILLS

Product Features

●The improved design enables better rigidity for high speed cutting.

• A stronger helical flute design helps improve workpiece surface finishes while maintaining good cutting edge sharpness.

The drill point angle is 125°, The chamfer angle is available as a 90°or 60°. Simultaneous centering and chamfering with one tool! Chamfering and groove 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 multifunction tool for groove machining.

●High precision machining can be achieved with the two stage point shape.
