Drill bit for heavy-duty metalwork
This 51/64-inch high-speed steel drill bit is built for demanding metal-drilling tasks. The Killer Force design and split-point tip reduce walking and deliver fast, accurate starts in tough materials. Its 1/2-inch reduced shank allows use with standard 1/2-inch chucks despite the large cutting diameter. The bit suits professional workshops and serious DIY projects requiring large-hole capacity.
Three-flat shank prevents slippage
The 3-flat shank locks securely in three-jaw chucks, eliminating spin-out under high torque. A flute length of 3 inches and an overall length of 6 inches provide deep drilling reach and effective chip clearance. The heavy-duty construction resists wear during extended use in steel and alloy. Buyers needing smaller diameters or longer reach for deep-hole drilling should consider other options.
