The DEWALT DWMT70782L 1/4-inch Angle Die Grinder is a pneumatic tool designed for heavy-duty grinding, blending, and finishing. It spins at 20,000 RPM free speed at 90 PSI, giving you rapid material removal and a smooth finish. The lightweight aluminum housing and ergonomic cushion grip reduce fatigue, while the touch-control trigger with self-locking throttle protects against accidental starts.
Whether you're smoothing welds, prepping metal, or porting and polishing, this angle die grinder offers the speed and maneuverability you need. The rear air exhaust directs air away from the work surface, helping keep your line of sight clear. Its compact angle head fits into tighter spots than a straight die grinder.
The touch control trigger lets you vary the amount of air, so you can feather the speed for controlled work or open it up for aggressive grinding. The self-locking throttle stays where you set it, which is more comfortable for extended use. A 1/4-inch collet accepts standard mounted points, carbide burrs, and sanding accessories.
This air die grinder requires a compressor that can deliver sufficient volume at 90 PSI. A typical 6-gallon or larger compressor is enough for light grinding, but continuous heavy work may need a bigger tank. Use a lubricator in your air line to keep the tool running smoothly.
20,000 RPM: fast material removal and smooth finishing.
Lightweight aluminum body: reduces hand fatigue.
Rear exhaust: keeps air and debris away from work.
Touch-control trigger: variable speed and anti-accidental start.
1/4-inch collet: compatible with standard grinding and finishing accessories.

An angle die grinder has a geared head that positions the accessory at a right angle. This design is easier to control when working on flat surfaces, inside corners, or in tight spaces. Straight die grinders are better for reaching deep bores. For general metalwork, blending, and finishing, the angle format is often more practical.
Air tools run best with clean, dry, and lubricated air. Add a small amount of air tool oil into the air inlet before each use, and consider a water separator if your compressor doesn't have one. This simple maintenance keeps the motor spinning freely and prevents rust inside the tool.
Always wear eye protection, gloves, and a dust mask when grinding. Secure the work piece, let the grinder reach full speed before touching the material, and never force the tool. Let the abrasive do the work.
Yes, it's pneumatic and performs best with a compressor that can deliver 90 PSI and sufficient CFM.
With a 1/4-inch collet, you can use small mounted cut-off wheels and rotary burrs designed for die grinders. Always use the correct arbor or collet size.
The touch-control trigger lets you modulate the air flow, giving you control over speed.
20,000 RPM at 90 PSI.
Powerful little grinder.
This die grinder has plenty of rpm for porting work. The throttle is smooth and the rear exhaust keeps dust out of your face. The body is lightweight.
I'm a metalworker and I needed a small grinder for tight spaces. This one is excellent. The 20,000 rpm makes quick work of welds. The swivel throttle took a little getting used to, but now I like it. It's comfortable to hold for extended periods. The rear exhaust is a great feature. I've used it almost daily for a month and no issues.
Works great on cast iron. The grip is comfortable and it runs smooth. Good quality for the price.
I bought this for a metal art project. It spins fast and is easy to control. The only downside is that it gets loud, but that's expected.
I've used many die grinders over the years, and this one is solid. It's got plenty of power for deburring and grinding. The body is aluminum, so it's durable but not heavy. The throttle self-locks, which is good for continuous use. I wish it came with a case, but that's minor. Overall, it's a reliable tool that I'd recommend.
