1/2" HSS reduced-shank drill bit for 3/8" chucks

This Drill America bit lets you bore a 1/2" hole using a drill with a 3/8" chuck. The reduced-shank design bridges the size gap without needing a larger tool. It suits mechanics and fabricators who occasionally need that diameter but do not own a half-inch capacity drill. The silver-and-deming style is a workshop staple for steel and cast iron.

Surface-treated HSS flutes and 4-1/2" flute length

High-speed steel with surface-treated flutes resists wear and clears chips efficiently in ferrous metals. The 4-1/2" flute length and 6" overall length give reach for deeper holes while keeping the shank short enough for standard 3/8" chucks. The straight shank locks securely in keyless or keyed chucks. Not suited for production runs that demand cobalt or carbide tooling.

Highlights
