Gashing of a 4 Flute End Mill
One of the simple ways to gash a 4 flute is the cut a cross roughly 1/16" wide @ 45° to the flutes, roughly 1/16" deep or so. Too much weakens the end mill. That relieves the center of the end mill, providing the necessary clearance for the wheel that will sharpen the end, and grind the secondary relief. It also provides clearance for a wheel ...
