Elite Series - 25 Grit Single 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.

- Single-segment configuration for aggressive cutting on light machines — a single segment per shoe creates less surface contact than a double, which means faster cutting speed and more aggressive material removal at the trade-off of shorter tool life. Recommended for grinders 25" and smaller, where the lighter machine weight benefits from the increased per-diamond pressure that a single segment delivers.

- 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. A clean cut at 25 grit is what makes every step afterward faster — leave scratches here and you chase them all the way to the final resin pad.
