Elite Series - 16 Grit Double Segment Gold Hard Concrete

- Most aggressive metal-bond grinding segment in the Elite line — 16 grit is the coarsest standard size, designed to tear through thick coatings, heavy mastic, epoxy overlays, glue, and badly worn or contaminated concrete surfaces in a single aggressive pass.

- 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. For aggressive stock removal on smaller machines, a single-segment 16 grit cuts faster but wears out sooner.

- Engineered for hard concrete — hard concrete (typically 5,000+ PSI, Mohs 7+) doesn't wear diamonds down enough to keep them sharp, causing standard-bond segments to "glaze" and slide across the surface without cutting. The gold color code in Simiron's Elite range designates an extra-soft metal bond, engineered to wear away faster on purpose so fresh diamond is continuously exposed.

- Counterintuitive but correct: soft bond on hard concrete, hard bond on soft concrete — using a hard bond on a hard slab causes glazing, where the diamonds polish smooth and stop cutting entirely. Gold sits one step beyond blue in softness: use blue for medium-to-hard concrete, step up to gold when the slab is exceptionally hard, power-troweled, or showing glazing with a blue bond.

- Step-zero tool for heavy prep jobs — use this before stepping up to 25 grit when the floor has thick coatings, severe surface damage, or major profile correction needs. After the 16-grit opens the floor, the typical sequence moves up through 25, 40, 80, and 100-grit metals, then into transitional and resin polishing pads. Leaving deep scratches at this stage is fine — the next grits are designed to remove them.
