If you want very fast cutting speeds and work with natural woods (hard and soft), and you want a great finish at the same time, this is the end mill to use. The end mill appears similar to a roughing (hog) end mill, but doesn't exhibit as many serrations. The geometry will provide a flat surface
This is one of the best end mills for single pass (full depth) cutting at very high speeds. The chip load per tooth for the 1/2" cut diameter end mill is .021 to .023 (hard woods).
