Norseman 37680 10mm Cobalt Spot Weld Twin End Drill Bit
This rugged high performance drill is designed to effectively cut auto body panel spot welds. The high red hardnessof cobalt steel permits speeds 30% greater than H.S.S.drills. Cobalt steel is substantially more abrasion resistant, resulting in very long wearing cutting edges. The spur point on the Type 186 is designed to cut through the weld on one panel while leaving the second panel free of holes. The modified point on the Type 187 drill is chip resistant with slightly greater penetration into the second panel.
Spot weld Size = 3/8
Overall Length = 3.62
