Drilling Hardened Metal

Conquer the toughest materials with our pro-grade selection of drill bits engineered for hardened steel, stainless, titanium, Inconel, and other extreme alloys. Whether you’re fabricating aerospace parts, working in a machine shop, or tackling industrial maintenance, these cobalt and solid carbide tools deliver unmatched heat resistance, edge retention, and clean penetration. Built to handle work-hardening and brutal feed conditions—because failure isn’t an option when you’re drilling the hard stuff.

Success with drilling hardened metal often comes down to choosing tooling that can hold its edge under heat and pressure. The best drill bits for drilling hard metal should match the material hardness, hole size, and machine setup. When drilling through metal that resists standard bits, slower speeds and proper cutting fluid can help protect the cutting edge. For tougher jobs, drilling hardened metal calls for patience, rigidity, and the right bit geometry.
