The self-feed style forstner bits have a lead auger screw which will pull its way into the log and with multi spur saw teeth this bit will make safe, easy work of drilling holes. Made from High Speed Steel these bits will drill a clean hole however you must reverse the bit out of the wood. The self feed bits can only be used in a heavy-duty ½" hand drill, not in a drill press and come in 1", 1 ½", 2" & 3" sizes.
