Product Description

These threaded-shank drill bits meet National Aerospace Standards (NAS) 965 Type D guidelines for drill bits used in aircraft repair and production. Cobalt threaded-shank drill bits tolerate higher drilling speeds and are harder and more wear-resistant than high-speed steel threaded-shank drill bits. They can drill harder materials than high-speed steel drill bits.
