This 7-inch Rotary Car Polisher features a brushless motor for efficient performance and runtime. No-load speed of 800-2200 RPM with the variable-speed trigger and dial allow for use on cars, headlights, windshields, fiber glass, gelcoat, and for glass-polishing applications. The included 7-inch backing plate is recommended for most applications.

Review: A politriz é fácil de usar e funciona muito bem. É potente, e talvez exija uma bateria de maior capacidade. Mas é uma Dewalt. Muito boa.
Review: 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.

*by C***S on 21 December 2021*

Es una muy buena pulidora, tiene mucha fuerza, se siente fuerte y de buena calidad, pero debes tener buenas baterías, en lo personal yo tenía dos de 2mh y se las acaba de volada, me duran completas como 7 minutos de pulir con cada pila, yo recomiendo que uses pilas dé 5mh para que te aguante más. Pero la recomiendo.
