PLUNGE RATE – This is the speed at which the bit enters the wood. Keep in mind that End Mills are meant to cut from the side whereas drills are meant to cut vertically. You can not plunge an end mill into material like you would a drill bit. For most woods, I usually set the Plunge Rate to 10 mm/sec or less.
