13/64-Inch Black Oxide Drill Bit, Tri-Cut Shank, 10 Pack, Jobber Length

OEM Tools 13/64" Black Oxide Jobber length drill bits that are designed for jobsite durability and extended life. Our web geometry has a thicker core than a standard drill bit, providing the user with maximum strength; helping eliminate side-load breakage. We added a unique parabolic flute that keeps the bit running cool. A standard 135 Split Point tip starts on contact; eliminating 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 Tri-Cut shank won't slip in the drill chuck. Bits above 3/8" diameter have a reduced shank diameter for use in 3/8" chucks.
