Reduced compared to smooth surface. For this reason, the frictional force which arises between the surface of the chip formation part 8 and chips can be reduced. As a result, the chips pass through the chip forming unit 8 more smoothly. In addition, since the frictional force between the chip forming portion 8 and the chips is reduced, drill vibration and chatter are also reduced.

Therefore, the effect of reducing the frictional force between the above-described chip forming portion 8 and the chips is maintained for a long time.
- the chips continuously scraped from the workpiece are deformed (curled) in contact with the chip forming portion 8 and then broken, and then completely released from the workpiece. For this reason, by making the wall surface downstream from the chip forming portion 8 a smooth surface, the flow of chips and cutting oil is not hindered, and the first chip discharging groove 5A and the second chip discharging groove 5B. Chips can be discharged smoothly toward the rear end side.
