Frequently Asked Questions
Q: What materials can this HSS spot weld cutter drill bit work on?
A: This HSS cobalt spot weld cutter is designed primarily for use on sheet metal, automotive body panels, and mild steel surfaces. The HSS cobalt construction provides excellent durability and heat resistance, making it suitable for repeated spot weld removal on metal fabrication and auto body repair projects.
Q: What is the difference between the 8mm and 10mm spot weld cutter sizes?
A: The 8mm (5/16") cutter is ideal for smaller spot welds commonly found on thinner gauge automotive panels, while the 10mm (3/8") cutter suits slightly larger or heavier spot welds. Choose the size that best matches the diameter of the spot welds you need to remove for the cleanest results.
Q: Is this spot weld drill bit compatible with a standard hand drill?
A: Yes. The flat straight shank on this spot weld cutter is designed to fit securely into the chuck of any standard corded or cordless hand drill, as well as a drill press. The flat-sided shank prevents the bit from rotating in the chuck, ensuring stable, accurate drilling with every use.
