I tell ya what, I’m never using harbor freight cut off wheel again. Just had a brand new, fresh out of package one explode in mid air without touching anything. All I did was hit the trigger and it came a part. Rated for 12000 rpm. My cut off wheel spins 9,000. Took the wheel into my chest, thru the leather welding jacket. Feels like a bunch of tiny frozen paint balls hitting ya.
