Categories : tools
SKU : WOR-TOO-706
The DEWALT DCG426M2 is a variable-speed die grinder powered by the 20V MAX system, ideal for metalworking, cutting, grinding, and surface preparation. This kit includes two batteries, charger, and a rugged kit box.
The dial lets you set the speed from 8,000 to 28,000 RPM, so you can match the tool to the material and task. Use lower speeds for polishing and higher speeds for fast material removal.
One of the most common questions about the DCG426M2 is what collet sizes it accepts. The grinder comes with a 1/4-inch collet for standard accessories, and you can swap to a 1/8-inch collet (sold separately) for precision burrs and smaller bits. Replacement collets are available to keep your tool ready when wear or damage occurs.
The spindle lock and the included wrench make changing accessories quick, while the adjustable guard helps direct sparks and debris away from you.
This kit includes two DEWALT 2Ah batteries and a charger, but the tool works with any DEWALT 20V MAX battery, so you can share power across your existing lineup.
For metal fabricators, welders, and auto body workers, the DCG426M2 offers cordless freedom without sacrificing performance.
Variable speed dial (8,000-28,000 RPM) matches tool speed to the job.
Accepts 1/4-inch and 1/8-inch collets for versatile accessory use.
20V MAX battery platform compatible with other DEWALT tools.
Includes two 2Ah batteries and charger for extended runtime.
Adjustable guard and spindle lock provide safety and quick changes.

A real monster. Good power.
Used this to port my cylinder head. Variable speed is smooth and the tool free guard makes switching wheels easy. It's a little bulky but worth it.
I've ground down a lot of welds in my time, and this cordless die grinder handles like a top. The speed dial lets you start slow to avoid kickback, then open it up for stock removal. I got a full afternoon of use on one 5Ah battery. The spindle lock is convenient for changing wheels. It is a little larger than a pneumatic, but not by much. After two months on a fab project, it still feels new.
Great for cleaning up aluminum. No cord to tangle.
I bought this for my husband, and he hasn't stopped using it. It's quiet for a grinder and has plenty of speed. The case is nice to keep everything organized.
This thing eats through cutting wheels like crazy, but that's expected. I used it to cut some steel and it did the job. Just wish it came with a spare nut.
Smooth as butter.
I've used air die grinders for decades, and I was curious if battery power could keep up. This one does. It has enough torque for heavy burrs, and the speed control is precise. The brushless motor runs cool, even when I'm deburring a whole trailer frame. The only complaint is the guard is a bit hard to adjust, but you rarely need to move it. For independent work without an air compressor, this is my go-to.
Love this little grinder!
Used it to grind out a bad weld on my truck. It performed flawlessly. Battery life is okay, not great.
I'm a metal art sculptor and this die grinder is in my hands daily. The variable speed lets me go from rough grinding to fine sanding. It is heavier than my pneumatic, but not having a hose is a huge plus.
My husband passed and left me his workshop. I didn't know what to do with all his tools, but my grandson showed me this grinder and it is actually fun. The instructions are clear and the battery charges quickly. I used it to sharpen my garden tools? No, that's a bench grinder. Anyway, it's a quality tool. The price is steep, but DEWALT doesn't disappoint.
