never gone to far through on the grinding and used a spot wed cutter with one tooth lots of times. I am not the best body man out there and not trying to be, but me and spot weld cutters don't get along real wellIt’s just practice, like anything else. Once you get the drill speed down they’ll last a long time if you don’t side load them a ton, you get a feel for when you’re doing something that’ll break ‘em. And you can use them missing a tooth or two if you’re careful.
Might have been necessity for me though, no way I can be precise enough with a grinder to do that stuff. I’d have a whole lot of welding to do.
