{"product_id":"6-grit-metal-double-segment-hard-bond-black","title":"Segmento doble de metal de grano 6 - Unión dura negra","description":"\u003cp\u003e\u003cstrong\u003e- The most aggressive metal-bond grinding segment available\u003c\/strong\u003e — 6 grit goes below the standard 16-grit \"coarsest\" tier, designed for extreme stock removal where even a 16 grit isn't fast enough. Tears through the thickest coatings, heavy industrial mastic, multi-layer epoxy overlays, severe surface deformities, and badly damaged or contaminated slabs that need significant material removed before a normal grinding sequence can begin.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- Double-segment configuration for tool life on extreme prep\u003c\/strong\u003e — two diamond segments per shoe create more surface contact than a single segment, extending tool life and stabilizing the cut. Best paired with \u003cstrong\u003elarger \/ heavier walk-behind grinders (25\" and up)\u003c\/strong\u003e where the extra contact patch and weight help the segment cut effectively at this coarse a grit. At 6 grit specifically, the goal is still speed, but the double-segment layout keeps the tool from burning out as fast as a single-segment version.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- Engineered for soft concrete\u003c\/strong\u003e — soft concrete (typically under 2,500 PSI, Mohs 3–4) is highly abrasive and wears diamonds out fast. The hard metal bond holds the diamonds in place longer, giving usable tool life on a slab that would chew through softer bonds in a fraction of the time. The black color code is the universal industry marker for hard-bond soft-concrete tooling.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- Counterintuitive but correct: hard bond on soft concrete, soft bond on hard concrete\u003c\/strong\u003e — using the wrong bond on a soft slab causes premature wear and burns through tooling budget. Black sits one step below orange in bond hardness: use black for standard soft concrete, step up to orange when the slab is exceptionally soft or abrasive (under 2,000 PSI, Mohs 2–3).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- Leaves a deep scratch pattern by design\u003c\/strong\u003e — at 6 grit, expect visible groove lines, exposed aggregate, and a rough surface. That's the point. After this pass, the progression must step up through 16, 25\/30, 50, 80, and 100-grit metals before transitioning to resin pads. Skipping steps after a 6-grit cut will leave a scratch pattern that resin pads cannot remove. Specialist tool for severe prep on soft slabs — most jobs start at 16 or 25 grit, but when the floor combines extreme coatings with soft concrete underneath, 6-grit black is the right choice.\u003c\/p\u003e","brand":"Xiamen Murat Tool Ltd.","offers":[{"title":"Default Title","offer_id":49613635846425,"sku":"40006839","price":32.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0883\/9803\/7273\/files\/BC_Upload_4086ac6b-ee74-4fe8-9b1b-60d2b516c892.png?v=1726065780","url":"https:\/\/shop.simiron.com\/es\/products\/6-grit-metal-double-segment-hard-bond-black","provider":"Simiron","version":"1.0","type":"link"}
