Brushless 20V MAX XR angle grinder with a 5-inch capacity, paddle switch, and tool-free guard for cutting, grinding, and sanding – tool only.
Categories : tools
SKU : WOR-TOO-631
The DEWALT DCG415B 20V MAX XR angle grinder gives you the power to cut, grind, and sand without a cord, using the same batteries as your other DEWALT tools. This bare tool version does not include a battery or charger, so it's perfect if you already own 20V MAX batteries. The brushless motor runs cooler and longer, and the 5-inch wheel capacity lets you take on tough metal and masonry projects.
The paddle switch keeps your fingers in a natural position and offers a lock-off for safety. The grinder is built with a low-profile gear case that fits into tight spots, and the tool-free guard allows quick adjustments when you need to change the cutting direction.
Because this is a bare tool, you can pair it with any 20V MAX DEWALT battery you already own—from the compact 1.5Ah pack to the high-capacity 6Ah or FlexVolt batteries (they work as 20V). That keeps cost down if you're already in the DEWALT ecosystem.
If you're a contractor or homeowner who needs a second grinder or wants a cordless option for on-site work, this paddle-switch grinder is a strong choice. It's lightweight enough for overhead work and powerful enough for continuous cutting.

Brushless motors are more efficient than brushed versions, meaning you get more cut-off wheel spin time per battery charge and a longer tool life. The DCG415B is built for continuous work, and the 5-inch wheel size gives you an edge over compact 4-1/2-inch grinders.
Match the disc to the material: thin cutoff wheels for sheet metal, grinding wheels for welds and rust, flap discs for blending. The tool-free guard makes it easy to position the wheel guard for the best visibility and safety.
No, this is a bare tool. It works with any DEWALT 20V MAX battery.
It fits 5-inch (125 mm) grinding wheels and cutting discs with a 5/8-inch arbor. Some 4.5-inch accessories can be used with the included guard positioning, but always check clearance.
Yes, it requires steady pressure to keep the grinder running and has a lock-off to prevent accidental starts.
The brushless motor runs at a constant 9,000 RPM.
Yes, FLEXVOLT batteries are backward compatible with 20V tools, giving you longer runtime when using a large battery.
Best grinder I've had in my shop.
I use it for metal grinding. It has plenty of power and the paddle switch is easy to hold down.
I've burned through cheap grinders for years. This one is a different animal. The brushless motor is smooth and powerful. The paddle switch is much safer than a toggle. The tool-free guard adjustment is really convenient. The variable speed control is nice for different wheels. It's a bare tool, so batteries are extra, but I have plenty. Worth the investment for pros.
Powerful and smooth.
Really like the paddle switch. The guard stays where you put it. Great for cutting tile.
This is my first cordless grinder. It doesn't have quite the same runtime as corded, but the convenience is worth it. I used it to cut rebar and it didn't bog down. The handle is comfortable. The weight is balanced. It's a bit loud though. All grinders are. I'm happy with it.
Good power, heavy.
Works fine. The battery drains fast if you push it hard, but that's expected. I'd buy again.
Professional-grade tool. I've used it daily for metal fabrication. The variable speed is fantastic for polishing. The dust ejection keeps debris away from the motor. The slim body lets me get into tight spots. It's my go-to grinder now. Only downside is the price for the tool alone, but the quality justifies it.
