6H Grit Triangle Double Segment Black for Soft Concrete

- The most aggressive metal-bond diamond segment available — 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. Fits any walk-behind grinder using the Lavina-style mounting pattern (three 9mm holes).

- Triangle double-segment configuration — the triangular geometry creates a leading edge that bites aggressively into the slab, while the double-segment layout (two triangles per shoe) doubles surface contact for better tool life on extreme prep work. Best paired with larger / heavier walk-behind grinders (25" and up) where the extra contact patch and weight help the segment cut effectively at this coarse a grit.

- Engineered specifically for soft concrete — soft concrete (typically under 2,500 PSI, Mohs 2–3) is highly abrasive and wears diamonds out fast. The hard metal bond (the "H" in 6H) holds the diamonds in place longer, giving you usable tool life on a slab that would chew through a softer-bond segment in a fraction of the time.

- Leaves a deep scratch pattern by design — 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, not a regular sequence starter — most jobs start at 16 or 25 grit. Reach for 6 grit only when the floor presents extreme conditions: deep coatings to strip, surface deformities to grind out, or large stock removal that warrants the extra step. Used correctly, it can cut hours off a heavy prep job; used unnecessarily, it just adds a step and prolongs the grind.
