Machining for boring holes.
When the tooth is attacked, the direction of chip curling is the same as that of the spiral groove, so the chip will be discharged from the top of the hole, and it will not remain in the hole.
It is especially suitable for the blind hole machining of viscous materials.
For the thread with keyway in the hole, even intermittent cutting can also play a good cutting force.
