Blue Star Diamond - Easy Edge Edge Ceramic Cup Wheel 5" - 270 Grit

- A 5-inch 270 grit ceramic cup wheel built for the refining phase of concrete edge work, smoothing out the surface after the 100 grit honing pass and preparing the edge for the final 400 grit finishing step — delivering a progressively refined finish that blends cleanly with the polished main floor.

- 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.

- Lightweight and easy to handle compared to heavier metal cup wheels, with no need for variable speed control during operation — making it accessible for both newer operators learning edge work and experienced polishers looking to save time and reduce labor on the edges of large commercial floors.
