13 Pack Rotary Spot Weld Cutter Remover Sets Double Sided, 3/8'' HSS Drill Bits Hex Sheet Metal Hole Cutter Remover for Power Drill Spot Welding

Depth of the blades is really inconsistent and poor. The preinstalled blade (one in middle) was great as the blades were deep and therefore it would cut really well. But if you compare it to the other ones, you’ll see the other blades are far more shallow, and therefore cut dreadfully or not at all.

I used it to drill out few spot welds on my car, I had to use the thicker bit as the one with the crown did not work for me. It went blunt very quickly couldn’t even finish the job. Not worth the price in my opinion, I paid(£14.99). It might work for you, but I wouldn’t buy this again.

Good

Does the job as expected

Excellent product when used correctly. It comes with enough cutters to remove hundreds of spot welds.I have so far removed 50 plus welds with one cutter and it is still in good working order.Just make sure you use a 2mm pilot drill to mark the weld first. It centres the cutter for an effective cut.
