Elite Series - 16 Grit Double Segment Blue Medium to 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 medium-to-hard concrete — covers the broad middle-to-upper range of slab hardness (typically 4,000–6,000 PSI, Mohs 5–7). The blue color code in Simiron's Elite range designates a softer metal bond, which wears away faster on purpose to keep exposing fresh diamond. On harder concrete, a hard bond would glaze and stop cutting; this softer bond keeps the diamonds active throughout the grind.

- Counterintuitive but correct: soft bond on hard concrete, hard bond on soft concrete — using the wrong bond on a hard slab causes glazing, where the diamonds polish smooth and stop cutting entirely. If you see glazing on the job, the bond is too hard for the floor — blue is the softer option positioned between red (medium) and any extra-soft white/grey bonds for the hardest slabs.

- 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.
