Types of Auto Body Spotweld Drill Bits
Super Cobalt HSS Spotweld Drills
This tough, high-performance drill is useful for efficiently cutting auto body spot welds. Cobalt comprises 8% of this high speed steel drill resulting in elevated red hot hardness levels which permit the drill to operate at 30% higher speeds than standard HSS drills. The gold surface treatment adds durability and lubricity. Cobalt Spotweld drills are available in two point styles. Heavy-duty spur point drills are able to cut through the weld on one panel while leaving the second panel clear of marks. Modified point cobalt drills, in addition to being chip resistant, penetrate slightly into the second panel.

Titanium nitride (TiN) coated M42 cobalt steel spotweld drill bits are designed for drilling high-strength, high alloy steel which is common in the automobile industry.
