About Reduced-Shank Drill Bits

Commonly used in maintenance applications, reduced-shank drill bits have a shank that is smaller than the drill diameter, allowing the bits to drill holes that are larger than the drill chuck's typical capacity.

Also known as Silver and Deming drill bits, these bits have a cutting diameter that is greater than their 1/2"-dia shank and are typically used in a drill press.
