3PCS Spot Weld Drill Bits, High Speed Cobalt Steel Weld Cutter Drill Bit with Titanium Coating 1/4-inch (6.5mm), 5/16-inch (8mm), and 3/8-inch (10mm)

This worked much better than I thought. Buddy needed to remove the outer skin to a bed side and tasked me with removing it. Bought these drilled out the spot welds perfectly without drilling all the way through and ruining the part we needed to weld to. This is highly recommended for removing the outer skin of the vehicle for replacement. Removed well over 100 welds and will need to buy another. Recommend using a center punch in the middle of the spot weld to keep it centered. Use the spot weld remover until the panel you are removing pops. At that point you don’t need to go farther. Also, once you start to cut the weld work the bit in a circular motion to get the bare minimum cut. Great value, super easy to use, sharp and cuts well, if you are using them for auto body panels the largest size works best, the other two for anything else. Will be buying another set though, impressed it worked so well.
