Boride 7" Edger Coarse 30 Grit

- A 7-inch metal bond diamond edger wheel in a coarse bond, with 30 grit serving as the most aggressive edge grinding tool in the lineup — built for heavy material removal at perimeters, corners, and tight spaces that walk-behind planetary grinders simply can't reach. - The coarse bond matrix delivers maximum cutting power for the toughest first-cut edge tasks, making it the go-to choice for stripping thick coatings, knocking down high spots, and grinding hard troweled concrete along walls and door frames before stepping into finer grits. - Compatible with most hand grinders and walk-behind edge machines using a standard 5/8"-11 threaded connection, allowing it to integrate easily into existing edge grinding setups across a wide range of job site equipment. - Works effectively on hard, medium, and soft concrete in both wet and dry conditions, giving operators a heavy-duty option for the most demanding initial pass in the edge grinding sequence regardless of the concrete profile being worked. - The larger 7-inch diameter covers more surface area per pass than smaller edger wheels, helping operators move through aggressive perimeter grinding more efficiently on larger commercial floors where edge speed and coverage are critical to keeping pace with the main floor work.
