16H Grit DOT Segment Black for Soft 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 soft concrete — soft concrete (typically under 2,500 PSI, Mohs 2–3) is highly abrasive and wears diamonds out fast. The hard metal bond (the "H" in 16H) holds the diamonds in place longer, giving you usable tool life on a slab that would chew through a softer-bond segment in a fraction of the time.

- Counterintuitive but correct: hard bond on soft concrete, soft bond on hard concrete — using the wrong bond for the floor causes either premature wear (soft bond on soft floor) or diamond glazing where the tool slides without cutting (hard bond on hard floor). Run a Mohs scratch test before committing to a bond if you're unsure of the slab's hardness.

- Color-coded by manufacturer for quick identification — the black designation is Simiron's color code for this soft-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.
