{"product_id":"7-ceramic-cup-wheel-50-grit","title":"7\" Ceramic Cup Wheel 50 Grit","description":"\u003cp\u003e\u003cstrong\u003e- Ceramic-bond diamond cup wheel for aggressive edge prep\u003c\/strong\u003e — built on a 7\" cup format for use with 7\"-rated hand grinders and walk-behind edge machines. The ceramic bond cuts aggressively without the glazing and deep gouging that metal-bond cup wheels leave behind, blending the edge perimeter cleanly with the main floor and eliminating extra scratch-chasing passes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- Coarse-grit cutting step in the edge polishing sequence\u003c\/strong\u003e — the 50 grit fills the gap between heavy 30-grit removal and 100-grit refinement. Contractors typically recommend a 30 → 50 → 100 progression on harder concrete to avoid leaving deep scratches that finer grits can't blend out.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- Larger 7\" footprint for faster edge coverage\u003c\/strong\u003e — 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- 5\/8\"-11 threaded mounting for direct grinder fit\u003c\/strong\u003e — 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- Part of a complete edge polishing system\u003c\/strong\u003e — pairs with coarser ceramic cup wheels (30 grit) and finer ones (100, 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.\u003c\/p\u003e","brand":"Xiamen Murat Tool Ltd.","offers":[{"title":"Default Title","offer_id":52141665321241,"sku":"40006327","price":65.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0883\/9803\/7273\/files\/BC_Upload_506869e3-d1a7-400c-bb44-fb4f8ba992e7.png?v=1777584603","url":"https:\/\/shop.simiron.com\/es\/products\/7-ceramic-cup-wheel-50-grit","provider":"Simiron","version":"1.0","type":"link"}
