SMSDistributors Expert Notes The 2511/2560 siabite series is engineered specifically for high‑alloy steels and stainless steel, where ceramic grain dramatically outperforms aluminum oxide. The self‑sharpening effect maintains cutting speed, while the cooling additive reduces heat buildup — a major advantage when grinding stainless or hardened metals. These discs are an excellent upgrade from standard A/O quick‑change discs, offering longer life, faster cutting, and improved efficiency in demanding fabrication environments.
