Product Features

●An excellent surface finish can be obtained while maintaining cutting edge sharpness from the high helix flute design. ●Accuracy improvements are also achieved from the single end design. ●A design for higher rigidity enables high speed cutting. ●The breakage problem of the drill portion of the center hole drill has been solved.

• Simultaneous combining the center positioning and chamfering is possible. It can also be used as a multi function tool like groove processing.

●Higher precision machining can be achieved with the two stage point shape design. ●With a single end center point drill, the degree of chip space widens, so the chips are discharged smoothly.
