Eastwood 3/8in Double Ended Spot Weld Cutter
Product Review (submitted on September 12, 2009):
First off this thing does a good job of cutting around the actual spot weld. The problem though is that if you catch it funky in any way it will snap the teeth off. You can still cut with a few teeth missing until you ultimately catch it again and snap the rest off. If you purchase this just expect to purchase more bits and do yourself a big favor and drill pilot holes into the welds before you try to use this tool. If it starts walking you will end up breaking teeth. I may have tried something else first if I had known this but I prefer to not put a hole through both pieces if I don't have to.
