If the angle is zero, the tool does not cut in at all. Typical cutting angles may be 10-30 degrees depending on the material being cut. We have an entrance angle, and also a clearance angle on the back side of the edge, we want to make sure that the tool is not fed too fast so the wrong part of the tool crashes.

Importance of Using End Mill Angles. An end mill's cutting force consists of an axial and radial component. While the axial component presses the end mill against the holder, the radial component tends to bend the end mill and causes vibrations. The fraction of axial force increases with an increasing helical angle; all the force is radial on a ...
