Blue Star Diamond - Easy Edge Edge Ceramic Cup Wheel 7" - 50 Grit

- Larger 7" footprint for aggressive edge prep — built with Blue Star Diamond Technology and a ceramic bond, the wider diameter removes material faster than the 5" version and is better suited to larger commercial slabs and walk-behind edge machines.

- Coarse-grit cutting step — the 50 grit fills the gap between heavy 30-grit removal and 100-grit refinement. Contractor reviews specifically recommend a 30 → 50 → 100 progression on harder concrete to avoid leaving deep scratches that lower grits can't blend out.

- 5/8"-11 threaded mounting — fits walk-behind edge machines and 7"-rated hand grinders directly, with no adapter or backing pad required. Always verify your grinder's RPM against the maximum operating speed marked on the wheel — 7" wheels run at lower max RPM than 5" wheels.

- Replaces metal-bond cup wheels for fast removal — cuts aggressively without the glazing and gouging that metal bonds leave behind, blending the edge perimeter cleanly with the main floor and eliminating extra scratch-chasing passes.

- Part of a complete edge polishing system — available in 30, 50, 100, 270, 400, and 800 grit in both 5" and 7" sizes, letting you build a full progression from aggressive cut to final polish using a single wheel format and mount.
