Review: Perfect for buffing boats with power and mobility - I bought this DEWALT cordless polisher to buff and restore the gelcoat on our boat and it’s been incredible. The cordless design makes a big difference when working around the hull, especially in areas where there’s no easy access to power. It has more than enough power to cut through oxidation, and the variable speed gives great control whether you’re compounding or doing a final polish. The 7-inch pad covers a lot of surface quickly, which is a huge plus when working on a boat. With a 5Ah battery I can usually get through an average-size boat without needing to recharge. It’s comfortable to hold, well-balanced, and doesn’t wear you out after long sessions. If you maintain your own boat or do marine detailing, this is an excellent tool. No cords, no hassle, just professional results wherever you need them. ## Features - Brushless motor of the car polisher is made for efficient performance and runtime - 7-inch backing plate of the variable speed polisher is recommended for most applications - DEWALT polisher features no-load speed of 800-2200 RPM for all types of applications - Variable speed on the trigger and dial helps to better control the tool during every step of the application - Rubber gear case overmold reduces surface imerfections and improves gripping surface - Can be held via the front grip or side handle ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07YQJLYNR | | Amperage | 1.5 Amps | | Brand | DEWALT | | Brand Name | DEWALT | | Customer Reviews | 4.6 out of 5 stars 1,849 Reviews | | Global Trade Identification Number | 00885911621762 | | Included Components | Polisher; 7" backing plate; Side Handle; Bail Handle | | Item Type Name | rotary polisher | | Item Weight | 2.18 kg | | Manufacturer | Dewalt | | Manufacturer Part Number | DCM849B | | Material | Metal | | Material Type | Metal | | Model Number | DCM849B | | Power Source | cordless-electric | | Speed | 2200 RPM | | UPC | 885911621762 | | Unit Count | 1.00 Count | | Voltage | 20 Volts | ## Product Details - **Brand:** DEWALT - **Included Components:** Polisher; 7" backing plate; Side Handle; Bail Handle - **Material:** Metal - **Power Source:** cordless-electric - **Speed:** 2200 RPM ## Images ![20V MAX* XR Cordless Polisher, Rotary, Variable Speed, 7-Inch, 180 mm, Tool Only (DCM849B) - Image 1](https://m.media-amazon.com/images/I/51TaNc5IQhL.jpg) ![20V MAX* XR Cordless Polisher, Rotary, Variable Speed, 7-Inch, 180 mm, Tool Only (DCM849B) - Image 2](https://m.media-amazon.com/images/I/51C2+15ZCAL.jpg) ![20V MAX* XR Cordless Polisher, Rotary, Variable Speed, 7-Inch, 180 mm, Tool Only (DCM849B) - Image 3](https://m.media-amazon.com/images/I/51JSJnS-6lL.jpg) ![20V MAX* XR Cordless Polisher, Rotary, Variable Speed, 7-Inch, 180 mm, Tool Only (DCM849B) - Image 4](https://m.media-amazon.com/images/I/518pMGgWqAL.jpg) ![20V MAX* XR Cordless Polisher, Rotary, Variable Speed, 7-Inch, 180 mm, Tool Only (DCM849B) - Image 5](https://m.media-amazon.com/images/I/51MgBMi5qYL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excelente. *by A***R on 31 March 2022* A politriz é fácil de usar e funciona muito bem.
