Elite Series - 16 Grit Single Segment Red Medium 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.

- Single-segment configuration for maximum cutting speed — 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, and the go-to choice anytime aggressive stock removal matters more than tool longevity.

- Engineered for medium concrete — medium-hardness concrete (typically 3,000–5,000 PSI, Mohs 5–6) is the most common slab type found on commercial and residential floors. The red color code in Simiron's Elite range designates a medium metal bond, balanced for this hardness to give steady cutting speed without premature wear or diamond glazing.

- The default choice when slab hardness is unknown — most contractors start here on a new job and switch to the harder (black, orange) or softer (blue) bond only if testing or visible wear shows the medium bond isn't matched to the floor. Run a Mohs scratch test before committing to a full set if accuracy matters.

- 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.
