Elite Series - 25 Grit Double Segment Blue Medium to Hard 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-to-hard concrete — covers the broad middle-to-upper range of slab hardness (typically 4,000–6,000 PSI, Mohs 5–7). The blue color code in Simiron's Elite range designates a softer metal bond, which wears away faster on purpose to keep exposing fresh diamond. On harder concrete, a hard bond would glaze and stop cutting; this softer bond keeps the diamonds active throughout the grind.

- 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, the bond is too hard for the floor — blue is the softer option positioned between red (medium) and any extra-soft white/grey bonds for the hardest slabs.

- 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.
