About Drill Bits

1/2" Diameter Reduced-Shank Drill Bits

Extended-Length 1/2" Diameter
Reduced-Shank Drill Bits

Access hard-to-reach spots and drill deep holes.

Cobalt Steel 1/2" Diameter Reduced-Shank Drill Bits

With better heat and wear resistance than high-speed steel, cobalt steel bits can run up to 25% faster and have a longer tool life.

Carbide-Tipped 1/2" Diameter Reduced-Shank Drill Bits

More wear resistant than cobalt steel and high-speed steel, 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.
