Elite Series - 80 Grit Double Segment Yellow Extremely Hard Concrete

- Fine-grit metal-bond grinding segment for transitional work — 80 grit sits at the end of the metal-bond progression, refining the scratch pattern left by coarser grits (16, 25, 30, 50) and preparing the slab for transitional and resin polishing pads. Removes the deeper score lines from earlier passes while leaving a uniform surface ready for the next polishing stage.

- Double-segment configuration for tool life and refinement — 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 larger / heavier walk-behind grinders (25" and up) where the extra contact patch helps the machine pull weight. At 80 grit specifically, the smoother scratch profile from a double segment translates directly into less work for the resin polishing stage that follows.

- Engineered for extremely hard concrete — extremely hard concrete (typically 7,000+ PSI, Mohs 8–9) includes power-troweled commercial slabs, high-performance industrial floors, and densified surfaces that defeat standard bonds entirely. The yellow color code in Simiron's Elite range designates the softest metal bond available, engineered to wear away aggressively so fresh diamond is continuously exposed even on slabs that would glaze every other bond.

- The last-resort bond when other tools have already glazed — yellow sits at the bottom of the bond-hardness scale: orange (very soft concrete) → black (soft) → red (medium) → blue (medium-hard) → gold (hard) → yellow (extremely hard). If gold tooling is glazing on a hard slab, yellow is the next escalation. If yellow glazes too, the alternative is reducing machine weight, slowing RPM, adding water mist, or applying silica sand to reopen the diamonds.

- Premium tier in the metal-bond range — Elite Series tooling carries higher diamond concentration and stricter QC tolerances than entry-level segments, delivering more consistent cut depth and longer usable life on commercial-volume work. The double-segment configuration compounds that value by extending the runtime per shoe, making this the higher-ROI choice for contractors running enough volume to justify the slightly higher per-unit cost.
