49/64in HSS drill bit with 1/2in shank
The Drill America KFD drill bit uses high-speed steel and a heavy-duty split point for accurate starts in metal and wood. Its 1/2in reduced shank fits standard drill chucks while the 3-flat design prevents slipping under load. The Killer Force label marks it for demanding workshop tasks.
3in flute length and 6in overall length
The 3in flute clears chips efficiently up to that depth, giving comfortable headroom for typical through-holes in structural steel or thick timber. Beyond the flute length chip evacuation drops off, so deeper holes need frequent withdrawal or a dedicated long-series bit. The 1/2in shank also limits use to chucks that accept that capacity.

Questions about this item
Will the 49/64 inch drill bit fit securely in my older drill press with a standard 1/2 inch chuck?
Yes, the 1/2 inch reduced shank is designed to fit standard 1/2 inch chucks on older drill presses and hand drills, while the 3-flat shank prevents slippage during heavy-duty use.
How can I verify the split point is centering correctly on hardened steel?
The heavy-duty split point should start cutting immediately without a centre punch; if the bit walks or requires excessive pressure at the 49/64 inch diameter, the point may need resharpening.
