Milwaukee 1" S&D Black Oxide Drill Bit

Description

The Milwaukee Thunderbolt 1" Silver & Deming drill bit is built for demanding work in stainless steel, cast iron, and materials spanning low to high tensile strength. Premium industrial-grade steel construction gives the bit body the toughness needed for repeated use in harsh conditions, while heavy-duty cutting surfaces maintain their edge through deep and shallow holes alike. The full 1-inch cutting diameter pairs with a 1/2-inch reduced shank, making the bit compatible with standard jawed drill chucks and keeping larger hole sizes accessible without specialized equipment. Milwaukee engineered the Thunderbolt Silver & Deming line for fast, accurate hole-making in hard metals.
