The Dormer Spot weld drill bit has specially designed lip and spur point to remove or drill out spot welded areas. It is commonly used for removing welds in a vehicle repair shop. Short flute length makes it more sturdy and less prone to shattering when being used in a hand held device. The bronze finish is a thin oxide layer and an indication for cobalt.
