A 230mm stone cutting disc (9" masonry cut-off wheel) is a heavy-duty abrasive consumable designed for mounting on large angle grinders and cut-off saws. Manufactured from silicon carbide grain bonded with synthetic resin and reinforced with fiberglass mesh matrix layers, it delivers clean, fast straight cuts through dense masonry materials such as concrete blocks, natural stone, brickwork, slabs, and paving tiles. Featuring a standard 22.23mm bore size and a flat Type 41 profile, it provides high dimensional stability and shatter resistance under heavy site cutting workloads.
