Now In: Tools → Tri-Ultra Cut → Weldout - Spotweld Drills: Type 492-D & 493-D
|
This rugged high performance drill is designed to effectively cut auto body panel spot welds. The high red hardness of 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 492-D is designed to cut through the weld on one panel while leaving the second panel free of holes. The modified point on the Type 493-D drill is chip resistant with slightly greater penetration into the second panel.
