Blue Star Diamond - Easy Edge Edge Ceramic Cup Wheel 7" - 270 Grit

- A 7-inch 270 grit ceramic cup wheel built for the refining phase of concrete edge work — the larger, higher-coverage size in the Easy Edge lineup, smoothing the surface after the 100 grit honing pass and preparing the edge for the final 400 grit finishing step across mid-to-large commercial floors.

- Made with Boride's Blue Star Diamond Technology, a ceramic bond matrix that holds diamond particles in place longer than resin alternatives — giving the wheel cutting characteristics that fall between a metal bond and a resin pad, allowing it to refine the surface efficiently while leaving a cleaner finish than a metal cup wheel would.

- Compatible with most hand grinders and walk-behind edge machines equipped with a 5/8"-11 threaded connection, and works equally well on hard, medium, and soft concrete in both wet and dry conditions — offering broad versatility across the full range of edge work encountered on commercial and residential polishing projects.

- At 270 grit, this wheel sits between the 100 grit honing step and the 400 grit finishing step in the Easy Edge sequence, giving operators a clearly structured progression that steadily builds the edge toward a refined, polished appearance matching the main floor.

- The wider 7-inch diameter covers more edge territory per pass compared to the 5-inch version, making it the preferred choice for experienced edge operators working on larger commercial floors where speed and coverage at the perimeter are just as important as finish quality.
