GMC power tools. Killed a grinder running it for about 15 minutes on a hot day over Christmas. Can't find receipt in a hurry so go to buy another and decide to get 7 power tool GMC set - grinder, hammer drill, sander, jigsaw, stud finder, electric screw driver, and something else which I forget at the moment for about $95.
Killed grinder on second use. Blown motor same as first.
Killed hammer drill on first use running circular saw through corrugated steel. Blown motor. And I was trying to use it intermittently so it wouldn't get hot.
Note to self. GMC tools are for 2 minute bursts or winter use. They just get too hot in summer after about 10 minutes and self destruct
