Reduced Shank Drill 7/8 HSS MPN:52456

These drill bits have three flats on their shank that help prevent the bits from slipping in the drill chuck when drilling at high speeds or under heavy loads. The bits are made from high-speed steel and provide more flexibility and absorb more shock and vibration than cobalt drill bits. Also known as Silver and Deming drill bits, these reduced-shank drill bits have a 1/2" shank and a drill diameter that is greater than 1/2". They can create larger holes than standard drill bits that have a 1/2" shank.
