Parts List: 1 × Welding Drill with Cutter 2 X Pilot Pins 11 X Extra 3/8inch Cutters Features: Our spot weld cutter set is a double-sided rotary cutter, and the blade can separate spot welded panels more efficiently than a panel cutter. It can avoid pause due to dull blades. Use the nails in the front to fix the solder joints and press down (there is a spring device at the nail back that can expand and contract). When the saw teeth contact the surface of the solder joint, the solder joint can be removed by rotating it with the power tool. High-temperature lubrication is a good way to extend blade serving life, but the tool is not required. Just replace the blades as they begin to dull.
