{"product_id":"7-cup-wheel-double-row-medium-bond-30-grit","title":"7\" Cup Wheel, Double Row, Medium Bond 30 Grit","description":"\u003cp\u003e\u003cstrong\u003e- Aggressive metal-bond diamond cup wheel for 7\" hand grinders\u003c\/strong\u003e — designed for fast stock removal, coating removal, leveling high spots, and general concrete prep with a 7\" angle grinder. The 30-grit metal-bonded diamonds tear through epoxy, mastic, paint, glue, and surface deformities aggressively, leaving a deep scratch pattern that calls for follow-up finer grits before coating or polishing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- Double-row segment design for fast cutting and balance\u003c\/strong\u003e — two parallel rows of diamond segments around the cup, typically 20–24 segments total. The double-row layout doubles the contact patch versus single-row turbo wheels, delivering steadier cutting on uneven slabs and better balance at speed. Cooling holes between segments aid dust evacuation and heat management.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- Medium bond for the most common concrete hardness\u003c\/strong\u003e — medium bond is balanced for typical commercial and residential slabs (3,000–5,000 PSI, Mohs 5–6) — the default choice when slab hardness is unknown. On much softer concrete, the medium bond will wear out faster; on much harder concrete, it may glaze and lose cutting action. Run a Mohs scratch test if slab hardness is in question.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- 5\/8\"-11 threaded arbor for direct grinder mounting\u003c\/strong\u003e — fits any 7\" hand grinder with a 5\/8\"-11 threaded spindle, no flange or backing pad required. Maximum operating RPM is typically 8,000–8,600; \u003cstrong\u003ealways verify the wheel's stamped max RPM against your grinder's rated speed before use.\u003c\/strong\u003e Suitable for wet or dry grinding, though dust shrouds plus HEPA vacuum are required for indoor work under OSHA silica standard 29 CFR 1926.1153.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- Distinct from ceramic-bond cup wheels\u003c\/strong\u003e — metal-bond double-row cups like this one cut more aggressively than ceramic-bond wheels (e.g., the Blue Star Easy Edge family) but leave a deeper scratch pattern that needs more refinement passes afterward. Choose metal bond for raw stock removal and coating strip; choose ceramic for smoother edgework that blends into a polished main floor.\u003c\/p\u003e","brand":"Xiamen Murat Tool Ltd.","offers":[{"title":"Default Title","offer_id":52141665681689,"sku":"40006549","price":67.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0883\/9803\/7273\/files\/BC_Upload_9f426747-76db-4126-8f90-9c464ad172dd.png?v=1777584609","url":"https:\/\/shop.simiron.com\/es\/products\/7-cup-wheel-double-row-medium-bond-30-grit","provider":"Simiron","version":"1.0","type":"link"}
