Okay, let me start by saying I was SO done with cheap die grinders. My Harbor Freight ones were basically expensive paperweights that occasionally spun. Then I discovered this DEWALT DWMT70782L and holy torque, Batman!
First off, that 20,000 RPM actually means something here. Unlike my old grinders that would whimper at first contact with metal, this beast powers through like it's nothing. Working on my project car's tight spots became actually enjoyable (who knew that was possible?).
The rear exhaust is genius - no more blowing debris right back at my face. And the trigger? So smooth I can control it with my pinky while holding awkward positions. Though fair warning: you'll need a decent compressor (my 30-gallon sometimes needs breathers during marathon sessions).
Pro tip the manual doesn't tell you: GREASE THAT SILVER FITTING! I learned the hard way after nearly seizing mine. An IR67 grease kit saved my bacon. Also, ear protection is a must - it's got that signature air tool scream.
Only gripe? Wish they made a 45° version too. But for the price compared to Snap-On? Absolute no-brainer. Just oil it religiously and this workhorse will outlast your projects.
