These are quality bits made to exacting standards in Japan. Self feeding bits feature a replaceable lead screw that feeds the bit into the work piece at a consistent rate. Excellent choice when you need to drill big holes free-hand as the lead screw prevents the bit from wandering. Do not use these bits in a drill press.
Several quality features set these bits apart from the rest:
-Teeth have a wider cutting surface for stability and truer holes. -Chamfered back edge for easier extraction of the bit from the work. -Lead screw has burr-free threads for a consistent feed rate. -Quick-change shank for fast and secure change-out. -Machined from hardened high carbon steel for extended durability.
