16S Grit DOT Segment Blue for Hard 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 hard concrete — hard concrete (typically 5,000+ PSI, Mohs 7+) doesn't wear diamonds down enough to keep them sharp, causing the segment to "glaze" and slide across the surface without cutting. The soft metal bond (the "S" in 16S) wears away faster on purpose, continuously exposing fresh diamond and keeping the cut aggressive.

- 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, switching to this softer bond (or reducing machine weight, slowing RPM, or adding water mist) reopens the diamonds and restores the cut.

- Color-coded by manufacturer for quick identification — the blue designation is Simiron's color code for the hard-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.
