Short-Length Drill Bits
Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than jobbers'- and maintenance-length drill bits.

Extended-Length Drill Bits
Access hard-to-reach spots and drill deep holes.
Black-oxide drill bits produce less friction than uncoated drill bits.

Extended-Length Cobalt Steel Drill Bits
Access hard-to-reach spots and drill deep holes. With better heat and wear resistance than high-speed steel, these cobalt steel bits can run up to 25% faster and have a longer tool life. The split point keeps the bit centered without a pilot hole.

Extended-Length Carbide-Tipped Drill Bits
Access hard-to-reach spots and drill deep holes. More wear resistant than cobalt steel and high-speed steel, these carbide-tipped bits maintain a sharper, harder edge at high temperatures for excellent performance on abrasive material, such as plastic. Because they aren’t as brittle as solid carbide bits, they can be used in less rigid setups, such as a hand-held drill.

Masonry Drill Bits for Drilling Rigs
Use these diamond-coated hollow bits for wet drilling of masonry, concrete, and rebar with a drilling rig. They're not for dry drilling or use with portable electric drills or grinders. The size listed is the bit’s OD.
Adapters let you use your bit on a drilling rig with a different thread size.

Replaceable Carbide-Insert Drill Bits
Use these bits to drill a large number of holes with high precision. When the cutting edges dull, replace the carbide inserts (sold separately) instead of the entire bit. Each drill bit requires two inserts—one on the inner cutting edge and one on the outer cutting edge. Bits can be used in CNC machines with coolant-through technology; holes in the bit allow coolant to be channeled through the tool for more efficient chip evacuation.
