The DEWALT DCM848B 20V MAX XR Brushless Random Orbit Polisher is a bare-tool solution for detailers and auto enthusiasts who want cordless freedom without compromising on finish. Its brushless motor runs longer per charge, while the variable-speed trigger and dial give you precise control from 2000 to 5500 OPM. The 5-inch backing plate paired with the 2.1-inch orbit is a balanced combination for most paint correction and finishing work.
This polisher is designed around one goal: consistent, controllable paint correction. The rubber gear-case overmold helps the tool sit comfortably in your hand, and the front grip or side handle gives you two-handed stability. It's a good fit for weekend detailers who want professional results and for shop pros who need a cordless option for quick touch-ups.
The DCM848B uses a 5-inch hook-and-loop backing plate, so stick with 5-inch pads for the best balance and orbit action. Use a firm foam pad for cutting compounds, a medium-foam pad for polishes, and a soft finishing pad for final gloss. Change pads when they become contaminated or worn.
The variable-speed trigger and dial let you start slow to spread polish, then build speed as you work. The 2000-5500 OPM range covers the spectrum from gentle finishing to aggressive defect removal.
Note: The DCM848B is a bare tool. A DEWALT 20V MAX battery and charger are required and sold separately.

The key to a great finish is matching the pad to the polish and knowing your speed. The DCM848B's 2.1-inch orbit makes it more aggressive than a typical 1.5-inch orbit polisher, so defects come out faster, but the pad still needs to stay flat to avoid shadowing.
Always prime a new pad with a few drops of polish, and work a 2x2-foot section at a time. Keep the backing plate clean so the hook-and-loop pad stays secure.
No, the DCM848B is sold as a bare tool. It requires a DEWALT 20V MAX battery and a compatible charger, both sold separately.
It uses a 5-inch hook-and-loop backing plate, so 5-inch pads are the recommended size.
Use 5-inch hook-and-loop foam pads. Choose a firm pad for cutting compounds, a medium pad for polishing, and a soft pad for finishing.
Yes, it is designed for car, headlight, windshield, and glass polishing applications.
The variable-speed trigger and dial provide a range of 2000 to 5500 OPM.
This polisher is a beast. It took my oxidized headlights from yellow to clear in minutes. The variable speed lets me control the process. It's a bit heavy, but with the handle it's manageable. The battery life is surprisingly good. I've also used it on my car's paint with a polish pad and it worked beautifully. Definitely a great tool for any garage.
Super smooth.
It does a good job on my boat. The battery drains fast on high, though.
I'm a beginner and this was very easy to handle. The orbital motion prevents swirls.
This is my go-to for polishing. It's smooth and doesn't bog down. The 5-inch pad is perfect for most cars. I've used it for years and it still runs like new.
I bought this for my husband's birthday. He said it's the best polisher he's ever used. The battery is long-lasting. Good quality.
It works well, but it's heavier than I expected. My arm gets tired.
My car looks brand new.
I used it to polish my RV. The results are good, but it's a little noisy.
It's so satisfying to see the shine. Very user friendly.
