1-3/8" HSS Killer Force drill bit

This Drill America bit is a high-speed steel accessory built for heavy-duty drilling in metal. Its 1/2" reduced shank fits standard drill chucks while the 1.3750-inch cutting diameter handles large hole applications. The split-point tip starts on contact to reduce walking and the three-flat shank prevents slippage in the chuck.

Sustained drilling performance

The high-speed steel construction resists heat buildup during prolonged cuts, maintaining hardness where lesser bits soften. Heavy-duty web thickness adds rigidity to reduce deflection when drilling deep through thick plate. The split-point geometry keeps chip evacuation steady so the flutes do not clog and the cutting edges stay cooler over long cycle times.
