Description

The DEWALT DWMT70784 is a 3-inch pneumatic cut-off/hand grinder built for controlled cutting and light grinding. Its self-locking touch control trigger holds the speed you set without constant finger pressure, and the cushioned grip isolates your hand from cold and vibration.

DEWALT DWMT70784 Pneumatic Cut-Off/Hand Grinder: Comfort and Control

Because the exhaust is directed out the rear, air and debris stay away from you and the workpiece. This makes the DWMT70784 a great choice for bodywork, metal fabrication, and general shop use in tight spaces.

Built for Continuous Use

The cushioned grip stays comfortable even as the tool gets cold from rapid air flow. Whether you're cutting off bolts or grinding down welds, the DWMT70784 responds to your touch.

Product Details

Pneumatic Power for Continuous Work

Unlike electric grinders, the DWMT70784 can run all day without overheating. The self-locking touch control reduces operator fatigue, making it easier to hold a steady hand on long cut-off jobs.

Why Rear Exhaust Matters

Rear exhaust keeps the cutting area clear and directs debris away from your body, improving both visibility and safety.

Ideal for Tight Quarters

A 3" wheel lets you get into corners and between components where larger grinders can't fit.

Frequently Asked Questions

What air pressure is required?

The tool operates best at a standard 90 PSI compressed air supply.

Can I use it with cut-off wheels?

Yes, it accepts common 3" cut-off wheels and grinding stones with a 1/4" arbor.

How does the self-locking trigger work?

Push the trigger to start and it stays in place, so you don't have to hold it continuously. Tap it to release.

Is it variable speed?

No, it runs at a fixed no-load speed, but the trigger allows you to control airflow for starts.

What maintenance is needed?

Regularly lubricate with air tool oil and check air fittings for leaks.

Handy grinder

Great little grinder for tight spots. The trigger control is responsive. I use it with 3 inch cut off wheels.

Great for porting

I needed a small grinder for porting cylinder heads and this works perfectly. It's lightweight and easy to control one-handed. The self-locking trigger helps me keep it running without squeezing all day. It takes standard 3 inch cutoff wheels. Air consumption is reasonable for my small compressor. Definitely a good addition to any shop.
