Drill America 57/64in HSS 1/2in Shank KFD Drill Bit with 3-Flat S

Heavy-duty drilling with 57/64 inch bit

This Drill America KFD drill bit is built for demanding metalworking tasks. It features a high-speed steel construction with a 1/2 inch reduced shank that fits standard industrial chucks. The three-flat shank design prevents slippage during high-torque operations. A heavy-duty split point ensures accurate starts without centre punching.

Replaces standard bits in tough alloys

Upgrade from general-purpose bits when drilling hardened steel or abrasive alloys where standard edges wear quickly. The Killer Force geometry resists chipping and maintains sharpness longer under heavy feed pressure. The jump is worth it for production runs that demand consistent hole quality and reduced tool changes. Not suited for buyers needing smaller diameters or non-ferrous-only applications.
