Elite Series - 40 Grit Single Segment Black Soft Concrete

- Mid-coarse metal-bond grinding segment for the second pass — 40 grit sits between the most aggressive cuts (16, 25) and the refinement stages (50, 80, 100). Removes the deeper scratches left by the coarsest grits while continuing to expose aggregate and shape the slab profile.

- 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 soft concrete — soft concrete (typically under 2,500 PSI, Mohs 3–4) is highly abrasive and wears diamonds out fast. The black color code in Simiron's Elite range designates a hard metal bond, which holds the diamonds in place longer to give usable tool life on an abrasive slab.

- Counterintuitive but correct: hard bond on soft concrete, soft bond on hard concrete — using the wrong bond on a soft slab causes premature wear and burns through tooling budget. Black sits one step below orange in bond hardness: use black for standard soft concrete, step up to orange when the slab is exceptionally soft or abrasive.

- 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 40 grit is what makes the 80 and 100 grit steps faster — leave scratches here and you chase them all the way to the final resin pad.
