Okay, let me start by saying I was skeptical at first. I've burned through so many cheap die grinders that I almost gave up on air tools altogether. But this DEWALT DWMT70782L? Absolute beast mode.

The 20,000 RPM power is no joke - it chews through metal like butter without bogging down. Finally found something that actually lives up to the specs! The rear exhaust is genius too - no more blowing debris back in my face.

What really surprised me was the control. That touch trigger lets me feather the power perfectly for delicate work. Been using it non-stop on my project car's tight spaces where my old HF grinders would just give up.

Pro tip though: GREASE IS YOUR FRIEND! Almost learned this the hard way until I discovered that sneaky grease fitting (why isn't this in the manual?!). Now I hit it with IR67 grease regularly and she purrs like a kitten.

Only complaint? My 30-gallon compressor needs breathers during marathon sessions, but that's not the grinder's fault. Ear protection recommended - it's got that signature air tool whine.

Bottom line: Worth every penny. Dewalt quality shines through where others fail. Just wish they made a 45° version!
