Elite Series - 80 Grit Single 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.

- Single-segment configuration for aggressive cutting on light machines — a single segment per shoe creates less surface contact than a double, which means faster cutting speed and more aggressive material removal at the trade-off of shorter tool life. Recommended for grinders 25" and smaller, where the lighter machine weight benefits from the increased per-diamond pressure that a single segment delivers.

- 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. At 80 grit specifically, that consistency matters more than at the coarser steps because any scratch left here translates directly into the resin polishing stage that follows.
