works great, one bit lasts about 50 spot welds, worth the money.

Worked well, glad to have the extra blades. 1st time used one and cut a bunch of welds before it wore out. Definitely will buy more soon to make cutting welds easier

Why did you pick this product vs others?:Good reviews

Great spot-weld cutters. They work fine as long as you’re careful with the pressure. I also pre-drill a small pilot hole to avoid wandering.

These are awesome, see pics. Use a good lubricant like cutting oil or ATF which I use. They are Very sharp.One cutter side and removed two inner fenders from a 72 plymouth Duster 340 and it’s still sharp and haven’t used the other side yet. That’s at least 100 welds. Cuts very fast so if you don’t want to cut through the back side or structural side if it’s to be welded against as in my case then I suggest go slow and take your time. I don’t spray or drip oil while I’m cutting instead I use a cheap generic ATF fluid in a cup or any trans fluid and dip the entire tip every 10-20 seconds. If you see smoke it’s time to cool it down and dip it In you choice of cutting oil or as I suggest and have done for decades, ATFThey arrived promptly and in a nice little plastic case to stay organized. Restoring another mopar and will be removing the full floor, full trunk, roof skin, quarters and inner fenders and I think these will last the entirety of my spot weld drilling for this project. With some left over.Can’t beat that many spot welds at this very reasonable priceVery highly recommendedPls find my review helpful if it is, thanks so much and enjoy your new spot weld cutters.

Works great!! Cuts spot welds super fast

These drills are actually " 3/8" " hole saws, as the pic shows. They are not capable of drilling the weld itself. One saw lasts about 5 welds in automotive sheet metal, with ATF as lubrication. These must be continually lubricated or else they will dull at the first cut. These are HSS, If the bit contacts the spot weld at any point it will not cut anymore. The drill is NOT 3/8", it's actually 10MM which is fine but the drive hex is also 10mm, so if you need an extension for the drill, the standard 3/8" hex extensions won't work. I ended up using a 10mm deep well socket connected to my drill as a driver. These drills must be engaged to the metal slowly. If you have a decent size job, order lots of these, or get a harder bit. I would order these again because they are inexpensive, just order lots.

The media could not be loaded. This tool works really well. Bits seem to be tough enough to last for a while. I cut out 5 spot welds with no problems and the bits don't seem to dull down. I used chainsaw bar chain oil for cutting. But use any cutting oil. There's plenty of extra cutting bits in the kit. When you cut your spotweld, predrill a little dimple beforehand. This gives a spot for the pin of the tool to stay centered. The pin is spring loaded so just push down when ready to cut. I used a 1/16 drill bit. Have fun.
