The DEWALT DCM849P2 20V MAX XR 7-Inch Cordless Rotary Polisher Kit is a serious tool for detailers, body shops, and DIY enthusiasts who want professional results without a cord. Powered by a high-efficiency brushless motor, this polisher delivers up to 75% more runtime than brushed models. With a variable speed range of 800 to 2200 RPM, you can handle paint correction, gel coat restoration, and glass polishing with accuracy. The kit includes two 6.0Ah DCB206 batteries, a charger, and a 7-inch backing plate.
The brushless motor is the core advantage of this kit. It runs cooler, lasts longer, and makes the most of every charge. The variable-speed trigger and dial let you tailor the speed to the task, while the 7-inch backing plate covers more surface area than smaller polishers, cutting down your buffing time.
The sideways battery pack lowers the center of gravity and improves balance, so the tool is more comfortable to hold for extended periods. A rubber gear case overmold reduces surface imperfections if you accidentally touch the paint, and it improves your grip. You can operate the polisher with the front grip or side handle, giving you better control around curves and tight body panels.
With the included 7-inch backing plate and speed range, this polisher is suited for compounding, polishing, and glazing on automotive paint, gelcoat, and fiberglass. It also works for headlight restoration and other glass-polishing tasks. As with any rotary polisher, a low speed is best for light-cut work, while higher speeds are useful for heavier correction.
This DCM849P2 kit comes with the polisher, two DEWALT DCB206 6.0Ah XR batteries, a charger, a 7-inch backing plate, and a carrying bag. The 4.8-pound weight (tool only) keeps the polisher manageable even on overhead sections.

A rotary polisher like the DEWALT DCM849P2 uses direct rotation to cut paint faster than a dual-action polisher. It's ideal for heavy correction work, gelcoat, and glass where you need aggressive material removal. If you're new to polishing, practice on a test panel first to learn how the rotary feels.
The included 7-inch backing plate pairs with 7-inch pads. Choose a foam pad with a cut that matches the polish you're using—a firm pad for compounding and a softer pad for finishing. Always keep the pad clean to avoid uneven wear.
The brushless motor is efficient, but polishing on high speed drains batteries quickly. Keep both 6.0Ah batteries charging and swap them out as needed. Consider a higher-capacity DEWALT battery if you're doing long sessions on a boat or RV.

Use 7-inch hook-and-loop foam pads. Choose a cutting pad for compounding, a polishing pad for finishing, and a soft pad for wax.
The tool weighs 4.8 pounds, which keeps it manageable for overhead work, especially with the sideways battery pack for balance.





Smooth, bro.
It does a great job on my car. The battery doesn't last as long as I'd like on high speed. But it's powerful.
I've been detailing cars as a hobby for years, and this polisher is worth every penny. The brushless motor is smooth and quiet, and the variable speed control lets me work on delicate clear coats. The 7-inch pad covers a lot of area, so I finished my wife's SUV in under an hour. The two 6.0Ah batteries lasted through the whole job. It's cordless, so I can move around without tripping over cords. The only complaint is the weight—it gets heavy after a while. But the results are professional grade.
I used this to polish the gel coat on my boat. It handled the curves well. The variable speed is useful. It's a bit heavy after an hour.
No cord to fight with. The battery power is surprisingly good. I did my whole SUV on one charge. The finish came out smooth.
