Threaded-Shank Drill Bits
Available450 products
Threaded-shank drill bits screw into a threaded adapter on a handheld drill to enable drilling in tight areas where standard drill bits that install into a chuck can't fit. They are commonly used for angle and offset drilling. The threaded connection also ensures the bits will not fall out of the drill. Threaded-shank drill bits have a self-centering 135° split point, also known as a crankshaft, that helps stop the bits from walking when starting to drill a hole.
NAS 965 Type D Cobalt Threaded Shank Drill Bits
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.
