Maintain Consistent Rotational Velocity Under Heavy Buffing Loads and Achieve Professional Grade Mirror Finishes Natively
The DEWALT DWP849 7-Inch to 9-Inch Variable-Speed Rotary Polisher is an industrial-grade surface refinement instrument engineered for professional automotive detailing, metal surface oxidation removal, and stone finishing. This heavy-duty corded power tool features a high-output 12-Amp motor integrated with electronic speed control circuitry that maintains consistent RPM output regardless of applied surface resistance. Outfitted with precision-cut heat-treated steel gears for quiet operation and a soft-start acceleration profile to prevent compound sling, this 6.7-pound machine provides the precise control necessary for elite-tier surface craftsmanship.
Best Used For:
- Automotive Clear Coat Restoration: Eliminating deep swirl marks, heavy oxidation, and surface scratches from paint finishes using steady speed compounds.
- Metal Surface Polishing: Buffing raw aluminum, stainless steel trim, and brass components to a high-luster finish on industrial machinery or trim parts.
- Stone and Granite Finishing: Honing and polishing natural stone countertops or architectural marble features to reach a glass-smooth reflective surface.
Key Performance & Safety Features
- Electronic Speed Regulation: Internal microcircuitry constantly monitors rotational resistance and adjusts motor voltage to hold set RPM profiles under pressure.
- Soft Start Acceleration: Motor engagement ramps up velocity incrementally at startup to protect liquid polishing compounds from flying off the pad.
- Precision Variable Speed Dial: Dual-range speed selector permits quick switching between 0-600 RPM for application and 0-3500 RPM for final high-speed buffing.
- All Ball-Bearing Internal Chassis: Professional-grade bearing architecture ensures smooth rotational tracking and reduces thermal heat buildup during long sessions.
- External Brush Access: Rapid-service motor caps allow operators to swap worn carbon brushes instantly without dismantling the tool housing.
What's Included
- (1) DWP849 7-Inch / 9-Inch Variable Speed Rotary Polisher Base Unit

PRO-TIP: When starting your polishing sequence, apply your compound to the pad and press the trigger lightly while keeping the pad flat against the surface to avoid splatter. Once the compound is spread, increase the dial speed to your target range; the electronic feedback loop will maintain consistent RPMs, allowing you to focus on steady, overlapping motion for a swirl-free finish.

Good mount but…
This is a solid mount for the Tesla monitor but the mounting points on the corner of screen caused my screen protector to bubble up. I had to return it unfortunately.

Tesla 😋😉 jeep phone mount.
Bought this to go in my jeep, perfectly attached to the corner of the screen of the screen, the only down side is since my screen raises and lowers over time with the vibration of the jeep it does make the screen slide down. But the magnet holds the phone very well as long as it is aligned properly to the back of the phone. I know it say tesla mount but my choice of smart stereo for my jeep is not a flush mount, it sticks out and has a cd player in the deck. As well the screen raises and lowers for access to to the cd player. So perfect for my jeep.

Amazing MagSafe phone stand
I recently purchased this MagSafe car phone mount, and it has been a game-changer for my daily commutes. The installation was effortless—just snap it onto the air vent, and you’re good to go.
What stands out the most is the strong MagSafe connection. My phone stays securely in place even on bumpy roads, and removing it is just as seamless. The minimalist design fits perfectly with my car’s interior, and it doesn’t block my view like other bulkier mounts.
Another highlight is the 360-degree rotation feature, which makes adjusting the angle for navigation or hands-free calls incredibly easy. It’s sturdy, reliable, and eliminates the need for clamps or adhesives.
Overall, this is a must-have for anyone who uses their phone for GPS or music while driving. Highly recommended for MagSafe-compatible phones!

Great Phone Mount
This is a great little phone mount! Simple and effective. I’ve been wanting something for when I am pulled over at a super charger to be on a call or watching something on my phone without holding it or putting it in the cup holder. Works super well with my MagSafe case although it does come with extra magnets as well in case you don’t have a MagSafe case. Highly recommend! Easily attaches to the screen, no sticky residue or risk of sun staining on the dash like other mounts.

Best one so far!
This is a great device! Not my first one but definitely better than I had before! It mounts on the side of the screen, which is very convenient as my other one was sticky, so I had to leave it with my other car. The handles rotate well to give you any position that suits you. There is some good suction, so it sticks well and doesn’t fall. It’s good quality and sturdy. The phone magnets very well to it and also doesn’t fall. I rotate it any way I want but mostly vertically and diagonally. I had it for a while now so can give you my honest opinion. Highly recommend!
