I've seen them broken but all I can say is that hits break everything. I mean everything Tips, chucks, translations, drives, screws. So if you have to spend $4 to buy a new one, you have to remember everything you break #2, the saws you burn, the masonry pieces you destroy by hitting rebar. If it breaks on the first try - you probably just got one batch of poor quality, I've had the same brand of saws that lasted me from a few cuts to several hundred cuts. Sometimes you just get a bad egg. Let it rip and get a new one. Don't let Marvin take your egg. He says he will return it, but he doesn't. He never does. That Sonova stealing eggs...
