The best grinder I've ever had. I use carbide blades for gouging aluminum welds in commercial shipbuilding. It is suitable for many difficult places. The smooth start of the engine is excellent. I can place it in a tight spot that no other grinder can reach and then it won't twitch on startup. Gives me complete control and is much more secure. I can hold him at arm's length and pull the trigger and he won't move the breaker one iota. I wish I had ordered it a few years ago.
