Drill Bit for Heavy-Duty Metalwork
This Drill America 17/32in HSS drill bit features a 1/2in shank with three flats for a secure chuck grip. The KFD Killer Force design incorporates a heavy-duty split point to reduce walking and improve penetration in tough materials. It suits professionals and serious DIYers drilling precise holes in steel and alloys.
Reduced Shank Fits Standard 1/2in Chucks
The 1/2in reduced shank allows use in drills that cannot accept larger diameters, freeing up the need for a specialist large-capacity machine. Its 3-flat profile prevents slippage under high torque, while the split point starts cleanly without a centre punch. Builders needing deeper reach or smaller step sizes will need different tooling.

Questions about this item
At what diameter does the 17/32 inch reduced shank become the limiting factor under sustained drilling?
The 17/32 inch cutting diameter with a 1/2 inch reduced shank means torque transfers through a smaller cross-section, making shank strength the first limit during heavy, continuous feed pressure.
How does the high-speed steel body and three-flat shank affect heat buildup and grip during all-day drilling?
High-speed steel retains hardness at elevated temperatures while the three-flat shank prevents chuck slippage, keeping the bit stable and reducing heat-related wear during extended use.
