DEWALT 20V MAX XR Cordless Polisher – 7-Inch Rotary, Variable Speed (Tool Only, DCM849B)

Overview

Elevate your detailing routine with the DEWALT 20V MAX XR cordless polisher. Built for efficiency and versatile performance, this 7-inch rotary polisher is designed to handle a range of finishing tasks—from automotive paint correction to delicate glass polishing—without being tethered to a power cord. The tool‑only format (DCM849B) lets you pair it with your preferred DEWALT battery and keeps you flexible on the job.

Power and Efficiency

At the heart of the polisher is a brushless motor that delivers smooth power delivery and optimized runtime. Combined with a no-load speed range of 800 to 2,200 RPM, you can tailor the pace to the material you’re polishing, whether you’re refining clear coats on a car or restoring a gelcoat surface on a boat. The 7-inch backing plate is a versatile choice for a broad set of applications and pad options, helping you achieve consistent results across jobs.

• Brushless motor for efficient performance and longer runtime
• 7-inch backing plate suitable for most polishing tasks
• No-load speed from 800 to 2,200 RPM for flexible use

Control and Handling

Precise control is a core focus with both a variable-speed trigger and a dedicated dial. This dual control lets you fine-tune speed during the process, helping you progress from light buffing to deeper cutting with confidence. A rubber gear case overmold adds grip and helps minimize surface blemishes during handling, while the polisher can be comfortably wielded from the front grip or the side handle for stability on curved or contoured surfaces.

• Variable-speed trigger plus dial for nuanced control
• Rubber overmolded gear case for improved grip
• Front grip or side handle options for versatile operation

Its cordless design supports mobility in workshops, garages, or on location, while the 7-inch backing plate and compatible pads provide a reliable setup for a range of detailing tasks. Always pair with suitable pads and compounds to suit the surface and finish you’re pursuing.
