Cornfuzzled yet again...
I have a couple of the air die grinders from HF. They are both still kicking after about a year. The straight one has a 3/8" carbide bur in it permanently and the 90* has a scotch lock arbor. I use the 90* more than the straight and it is starting to get just a bit of play. I think my dry air and frequent oiling is what keeps that cheap crap alive. :redneck:
I've had my 90* die grinder with a 3" cutoff wheel on it (one of those mail-order deals where you buy 100 3" cutoff discs and get the grinder free!:awesomework: prettyy much the HF equivalent), and have been using it on a professional level for almost 18yrs now...Damn thing developed a wicked nasty bearing howl from about yr 2, and it sounded like it's gonna blow apart at any given moment....still goin'!
What oil? :redneck:
