16 Grit 3" 10 Seg Metal- Medium Bond Red

- Most aggressive metal-bond grinding disc for small-grinder prep — 16 grit is the coarsest standard size, designed to tear through thick coatings, heavy mastic, epoxy overlays, glue, and badly worn surfaces in a single aggressive pass. The 3" disc format is sized for smaller floor grinders and edge machines where the larger 7"–10" tooling won't fit.

- 10-segment configuration for the 3" Redi-Lock platform — ten diamond segments arranged around a 3" / 80mm Redi-Lock or 2-pin compatible plate, designed to fit Husqvarna PG-series, STI/PrepMaster, Stonekor, and similar small-format grinders. Each segment delivers a discrete cutting point; the 10-segment count is the standard density for this disc size.

- 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 medium metal bond is balanced for this hardness to give steady cutting speed without premature wear or diamond glazing.

- Counterintuitive but correct: medium bond is the default starting point — most contractors start a new job here and switch to harder (for soft concrete) or softer (for hard concrete) bonds only if testing or visible wear shows the medium bond isn't matched to the floor. The red color code is the universal industry marker for medium-bond tooling.

- Step-zero tool for small-machine heavy prep — use this before stepping up to 25- and 30-grit metals when the floor has thick coatings or significant surface damage. After this pass, the typical sequence steps up through 30, 50, 80, and 100-grit metals, then into transitional and resin polishing pads. Best paired with a HEPA-vacuumed shroud for OSHA silica compliance during indoor work.
