### Why Use a Single Flute End Mill CNCCookbook Be A

At a given surface speed a 4 flute endmill can take 4 cuts at a given chip load (chip thickness) while a 2 flute only takes half as many. So the 4 flute might have 2x the MRR. This is why we see cutters with many flutes become popular in challenging materials that only allow fairly slow surface speeds.
