CHOOSING THE CORRECT ANGLE END MILL FOR YOUR JOB Helix angles generally come as low as 12° to as high as 60°. Most general purpose end mills use between a 25° and 30° angle where basic sharpness and cutting edge strength is maintained. Increasing the helix angle improves stock removal and is useful in machining at increased speeds and feeds.
