KnKut 10.0 Spot-Weld Drill With Boron CoatingKnKut Spot Weld Drills with Special Coating For Cutting Boron Steel are designed to effectively cut auto panel spot welds. Made of Cobalt Steel, the high red hardness permits speeds 30% greater than high speed steel spot weld drills. Cobalt Steel is substantially more abrasion resistant, resulting in a very long lasting cutting edge. KnKut Spot Weld Drills have a spur point, designed to cut through the weld on one panel while leaving only a slight penetration into the second panel. The modified point is chip resistant.
