Elite Series - 40 Grit Single Segment Gold Hard 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 hard concrete — hard concrete (typically 5,000+ PSI, Mohs 7+) doesn't wear diamonds down enough to keep them sharp, causing standard-bond segments to "glaze" and slide across the surface without cutting. The gold color code in Simiron's Elite range designates an extra-soft metal bond, engineered to wear away faster on purpose so fresh diamond is continuously exposed.

- Counterintuitive but correct: soft bond on hard concrete, hard bond on soft concrete — using a hard bond on a hard slab causes glazing, where the diamonds polish smooth and stop cutting entirely. Gold sits one step beyond blue in softness: use blue for medium-to-hard concrete, step up to gold when the slab is exceptionally hard, power-troweled, or showing glazing with a blue bond.

- 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.
