These carbide tipped drills are ideal for locksmiths, auto mechanics or any operator drilling into hardened steel. Can be used to drill out broken bolts, studs, taps and drill bits. They also cut hard steel such as safes, bearing races and dies. The carbide is designed to prevent chipping and dissipate heat quickly. These drills are designed solely for use in hardened steel and perform poorly in softer materials.
