It offers superior durability that lasts up to six time’s longer life than high-speed steel. Used to drill wood, aluminum, plastic, and other materials at greater cutting speeds than carbon-steel bits. Titanium-coated drill bits remain clean and accurate even in the toughest materials.
These High-Speed Steel bits made from carbon steel with the addition of other elements such as chrome and vanadium. This makes it ideal for use at high drilling speeds. The titanium Coating provided reduces friction for cooler, smoother running without lubrication that allows bits to last up to 4 to 5 times longer than steel drill bits.
