9/16" Shank High Speed Split Point Drill Bits

These large format drill bits feature 135° split point that keeps the drill from skating on hard surfaces. Also called “silver and deming˝, “blacksmith˝ or “prentiss˝ drill bits, they are designed to quickly cut through metal. They fit all 1/2˝ drills and drill presses and come with 3 flats on the shank to insure they are held securely in the chuck.
