"I ordered this bit set to drill through hydro-formed steel. These bits have faired VERY well against hardened steel. The cutting surface can be fairly brittle if you bind the bit but that's to be expected in most cases. These have a round shank if that's what you're looking for. Excellent selection of sizes and a nice case."
