É potente, e talvez exija uma bateria de maior capacidade. Mas é uma Dewalt. Muito boa. ### ⭐⭐⭐⭐⭐ Perfect for buffing boats with power and mobility *by on Reviewed in Canada 8 July 2025* 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. ## Frequently Bought Together - DEWALT 20V MAX* XR Cordless Polisher, Rotary, Variable Speed, 7-Inch, 180 mm, Tool Only (DCM849B) - CASOMAN 7-Inch Buffing and Polishing Pad Kit, 7 Pieces 7" Polishing Sponge, Waxing Buffing Pad Kit - DEWALT 7-in Wool Buffing Pad and Back --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/651049279-dewalt-dcm849b-20v-max-xr-7-in-180mm-cordless-variable](https://www.desertcart.tn/products/651049279-dewalt-dcm849b-20v-max-xr-7-in-180mm-cordless-variable) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-16*
