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.

HSS drill bits are highly durable bits designed for drilling into metal. Also known as high speed steel drill bits, they're constructed from carbon steel alloys that can handle the fast speed and heat generated when cutting materials like brass, steel and aluminium alloys. They're versatile enough to be used for other materials too, with split point tips ensuring precision irrespective of the surface type. Our range come either as singles or in HSS drill bit sets.

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. Our carbide drill bits for hardened steel are made in the USA and come with a solid C-2 grade carbide spade that can cut through hard steel and other high-strength materials.
