Product Description

This brushless small cordless angle grinder requires no time changing brushes, and offers a longer motor life. DEWALT cordless grinder offers a high level of protection. Its break stops the wheel in 2 seconds or less. The Kickback Break engages maximum force to stop the wheel when there is a pinch, stall, or bind-up to reduce kickback. The grinder will also shut off in those events to further protect the user. Battery and charger are sold separately.

I love my angle grinder from Dewalt! Purchased to complete a patio extension in our backyard. Used this tool to cut pavers we used to make the extension. Plenty of power! Make sure you get some larger capacity batteries to pir with the tool if you plan on heavy cutting/grinding. I would go through 3-4 (7ah cells) every day and charge every night.

I own an older version of the 20v Dewalt hand grinder. I gave it to my SIL and bought the newest version. I really like the paddle trigger and the adjustable guard. I use the grinder at home and the farm to sharpen blades for mowers and brush-hogs. I use 60 grit flap wheels for sharpening. A 6ah 20v battery will last a very long time.

Apesar da ferramenta ser profissional não recomendo para uma serralheria. Pois consome muito bateria. Mas para quem usa para soldar um pouco daqui a pouco usa pra cortar um cano ou sabe se lá oq. É muito versátil a potência e excelente e a praticidade de não ter bateria e ótima. Mas é necessária bastante bateria no mínimo 2 de 4ah e para uso constante não dá tempo de carregar uma enquanto usa a outra. Acredito que em uso sem desligar dure uns 20, 25 min.
