Elite Series - 25 Grit Double Segment Red Medium Concrete

- Aggressive metal-bond grinding segment for the first cutting pass — 25 grit is the standard starting point for most surface prep and polishing jobs. The cutting surface opens up the concrete, removes coatings, exposes aggregate, and creates the profile needed for subsequent grinding and polishing steps.

- Double-segment configuration for tool life and refinement — two diamond segments per shoe create more surface contact than a single segment, extending tool life and leaving a more uniform scratch pattern. Best paired with larger / heavier walk-behind grinders (25" and up) where the extra contact patch helps the machine pull weight. The smoother cut from a double segment also reduces the work needed at the next grit step.

- 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.

- Premium tier in the metal-bond range — Elite Series tooling carries higher diamond concentration and stricter QC tolerances than entry-level segments, delivering more consistent cut depth and longer usable life on commercial-volume work. The double-segment configuration compounds that value by extending the runtime per shoe, making this the higher-ROI choice for contractors running enough volume to justify the slightly higher per-unit cost.
