Our drill bits can make quick work of extremely hard ferrous materials and non-ferrous plastic, brass, iron, aluminum, steel platting, high-density resin, and cast iron, leaving a burr-free finished hole. This means a better-quality result once you finish drilling. Our carbide drill bits for hardened steel are made in the USA and come with solid C-2 grade carbide that can cut through hard steel and other high-strength materials. Our carbide drill bits are cryogenically treated to change the microstructure and phase constituent, providing you with an extremely hard cutting tool with superior drilling performance. The cryogenic treatment cools the carbide drill bits to extremely low temperatures, typically below -300 degrees Fahrenheit, using nitrogen gas. This process gives the carbide a more uniform and stable microstructure. State-of-the-art carbide drill bits for steel maintain peak performance even when used continuously at high temperatures. Their enhanced toughness reduces the likelihood of chipping or breaking, even under high-stress conditions. As manufacturers of over 10,000 solid carbide cutting tools, we’re confident you’ll love the quality of our bits. If you have inquiries regarding our selection, contact us today.
