Right yea I don't really like burning it either. I figure you could try it with a thinner haer drill chisel bit if you can find one that's really wide or you can get a thin set one like mine I got mine off of temu lol. I sharpened mine though I had to move back and forth to get it to go took some time but did the job I'm now pulling copper off the strings I have 25lbs of copper with strings and plastic and some insulated wires on it left to do i got 32 lbs cleaned already so not bad I guess. Wish I could test it on a bigger motor though. You can use the chisel bit for all sorts of things it's crazy if goes through think tubes as well not sure if it would go through a copper house pipe though but maybe. I like it alot though good thing I got it money well spent id say. Same with the ocilator I went with corded tools though except my impact is battery and I also have a battery drill and another sawzall. Drill is mainly used for wire stripper haha.
