Finishing speeds and feeds

Finishing chip load per tooth

Speeds and Feeds are based on slotting conditions with depth of cut equal to the diameter of the end mill.
When profiling, we recommend using a 5 flute GorillaMill running at 20% faster feed rates.
As a general rule, make the GorillaMill run harder and spin faster with a heavier chip load; that’s where the value is.
In fact, many machinists use the GorillaMill for roughing, as well as a superb finisher.
