I've got 2 Makita corded tools, a buffer that I bought last year, great tool, and a 4".angle grinder I bought in 1987.
The Makita 4" angle grinder is the standard by which I judge all corded power tools.
I have used and abused that thing for 32. Granted, it is not in daily industrial use but 32 years and counting is a damn good run.
The angle grinder has also taken more skin than any tool I've ever owned. It just doesn't care what it's grinding.
Loaned it to dad, told him to wear good leather gloves, he didn't, it took meat. Loaned it to my brother, told him to wear good leather gloves, he didn't, he still has the scar on the side of his hand.
I *expletive deleted*ing told 'em. Nobody ever listens to Larry.
