Cobalt Drills
Quality Cobalt drills. Another variation on the metal drilling theme. Cobalt drill-bits are the next step up the hardness scale from HSS drill-bits. They are designed to drill very hard materials, and will cope better with metals like stainless steel (although will still be blunted by some types). One useful DIY application is drilling out the remains of other broken drill-bits, although other harder bits may be better still.
