7" Ceramic Cup Wheel 200 Grit

- Ceramic-bond diamond cup wheel for transitional edgework — built on a 7" cup format for use with 7"-rated hand grinders and walk-behind edge machines. The ceramic bond removes material cleanly without the glazing and deep gouging that metal-bond cup wheels leave behind, blending the edge perimeter seamlessly with the main floor finish.

- Mid-grit refinement step in the edge polishing sequence — the 200 grit sits between the coarser cuts (30, 50, 100) and the fine-finish wheels (270, 400, 800). Removes the deeper scratch pattern from earlier passes and prepares the edge for resin polishing pads, lining up with the main floor's transition from metal-bond grinding into resin polishing.

- Larger 7" footprint for faster edge coverage — the wider diameter removes material faster than the 5" version of the same wheel, making it the preferred choice on larger commercial slabs and longer perimeter runs. The trade-off is a lower maximum operating RPM, so always verify your grinder's rated speed against the max RPM marked on the wheel.

- 5/8"-11 threaded mounting for direct grinder fit — installs on most 7"-rated hand grinders and walk-behind edgers without an adapter, flange, or backing pad. Suitable for both wet and dry grinding conditions, though dust shrouds plus a HEPA vacuum are required for indoor work under OSHA silica standard 29 CFR 1926.1153.

- Part of a complete edge polishing system — pairs with coarser ceramic cup wheels (30, 50, 100 grit) and finer ones (270, 400, 800 grit) to build a full edge progression that matches the main-floor polishing sequence. Choosing all ceramic-bond wheels for the edge avoids the scratch-chasing that happens when mixing metal-bond and ceramic-bond tooling in the same job — the 200-grit step is particularly important for matching the edge's surface profile to the main floor before resin polishing starts.
