HI-SPEED DRILL BIT R40 3/8*|These drills are made of high speed steel with a bright finish and a 118° point. They have been developed primarily for use in screw machines that require the use of short drills. They are made with short flutes and short overall length to provide maximum rigidity without sacrificing cutting ability. They are recommended for light duty work only – fracturing of the shank may occur under extreme pressure.
