1/2" Diameter Reduced-Shank Drill Bits
The shank has a smaller diameter than the tip, allowing you to drill large holes with machines that have small-capacity chucks. Also known as Silver and Deming bits, they have a 1/2” diameter shank.
Drill bits with flats on shank have three flat sides to prevent the bit from slipping in the drill chuck.

Carbide-Tipped 1/2" Diameter Reduced-Shank Drill Bits
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 hard and abrasive material. The shank has a smaller diameter than the tip, allowing you to drill large holes with machines that have small-capacity chucks. Also known as Silver and Deming bits, they have a 1/2” diameter shank.

Cobalt Steel 3/4" Diameter Reduced-Shank Drill Bits
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 shank has a smaller diameter than the tip, allowing you to drill large holes with machines that have small-capacity chucks. A split point keeps the bit centered without a pilot hole.
