16M Grit DOT Segment Medium Red for Medium Concrete

- Coarsest metal-bond diamond segment in the line — the 16-grit cutting surface is even more aggressive than the 25-grit, designed for the heaviest material removal: thick coatings, epoxy overlays, glue, mastic, paint, leveling compound, or major surface profile correction. Fits any walk-behind grinder using the Lavina-style "dot" segment pattern (three 9mm mounting holes).

- Engineered specifically 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 medium metal bond (the "M" in 16M) is balanced for this hardness, giving you 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) 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.

- Color-coded by manufacturer for quick identification — the red designation is Simiron's color code for the medium-concrete bond. Most contractors keep three-color sets on the truck (one bond per concrete hardness category) so the right segment can be selected on-site once the slab is tested.

- Step-zero tool for the toughest prep jobs — use the 16-grit before stepping up to 25-grit when the floor has heavy coatings or significant surface irregularities. After the 16-grit opens the floor and removes the bulk material, the progression moves up through 25, 50, 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.
