A precision start, 135 split point tip starts on contact to keep the bit from walking for fast accurate holes. Excellent for drilling on curved surfaces, requires less effort to drill and is highly recommended for use with portable drills. The 3-flat secure-grip shank won't slip in the drill chuck. Reduced shank diameter for use in 3/8 in. chucks.
