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.

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.

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.
