DeWalt makes cordless die grinders on the 20V MAX platform in 1-inch and 2-inch variants. Die grinders are precision tools for deburring, polishing, porting, and grinding in tight spaces where an angle grinder can't reach.
DeWalt 20V MAX Platform
Both models run on 20V MAX batteries. Die grinders at 25,000 RPM draw moderate current. A 2.0Ah pack is fine for intermittent use; 4.0Ah for extended sessions.

Frequently Asked Questions
What's the difference between a 1-inch and 2-inch die grinder?
The number refers to the maximum accessory diameter. A 1-inch die grinder is more compact and reaches tighter spaces. A 2-inch handles larger mounted points and surface conditioning discs. For most general-purpose work, the 1-inch is more versatile.
Can I use a die grinder for wood carving?
Yes. With carbide burrs or sanding drums, die grinders handle wood carving, shaping, and detail work. The 25,000 RPM spins faster than a rotary tool (Dremel-type), so start with light pressure and let the bit do the cutting.
