Per industry guidance, 30 grit is the recommended starting point when exposing medium-to-large stone aggregate, sitting between the most aggressive prep (16 grit) and the standard mid-cut (40–50 grit).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- Double-segment configuration for tool life and refinement\u003c\/strong\u003e — two diamond segments per shoe create more surface contact than a single segment, extending tool life and leaving a more uniform scratch pattern. Best paired with \u003cstrong\u003elarger \/ heavier walk-behind grinders (25\" and up)\u003c\/strong\u003e where the extra contact patch helps the machine pull weight. The smoother cut from a double segment also reduces the work needed at the next grit step.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- Engineered for medium concrete\u003c\/strong\u003e — medium-hardness concrete (typically 3,000–5,000 PSI, Mohs 5–6) is the most common slab type found on commercial and residential floors. The medium metal bond (the \"M\" in 30M) is balanced for this hardness to give steady cutting speed without premature wear or diamond glazing. The red color code is the universal industry marker for medium-bond tooling.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- The default choice when slab hardness is unknown\u003c\/strong\u003e — most contractors start a new job here and switch to harder (for soft concrete) or softer (for hard concrete) bonds only if testing or visible wear shows the medium bond isn't matched to the floor. Run a Mohs scratch test before committing to a full set if accuracy matters.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- Common starting grit for aggregate-exposed finishes\u003c\/strong\u003e — per industry guidance, 30 grit is the recommended first step when the goal is exposing medium-to-large stone aggregate (rather than the salt-and-pepper finish that starts at 70–120 grit). After this 30-grit pass, the typical sequence steps up through 50, 80, and 100-grit metals, then into transitional and resin polishing pads. A clean cut at 30 grit on the right bond is what makes every step afterward faster — leave scratches here and you chase them all the way to the final pad.\u003c\/p\u003e","brand":"Xiamen Murat Tool Ltd.","offers":[{"title":"Default Title","offer_id":49805841531161,"sku":"40006464","price":32.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0883\/9803\/7273\/files\/BC_Upload_62614742-6ff6-45aa-ae3e-b4f94236e1f3.png?v=1728921442","url":"https:\/\/shop.simiron.com\/es\/products\/30m-red-double-segment-medium-concrete","provider":"Simiron","version":"1.0","type":"link"}
