Rapida Cup Wheels feature a cap-cutter segment and a soft bond designed for powerful grinding on extremely hard concrete. This wheel excels on dense, smooth troweled floors and concrete strengthened with curing agents.During the curing process, surface curing compounds form a hard membrane over the slab. This prevents water from evaporating too quickly and strengthens the concrete cap. Once this rigid surface develops, standard tooling struggles to break through it.When the diamond bond is not matched to the hardness of the concrete, the diamonds can glaze. Glazing occurs when the bond does not wear away fast enough to expose new diamond edges. Using the correct bond is essential for efficient grinding, productivity, and avoiding premature wear.

The Rapida’s soft bond prevents this by maintaining aggressive cutting.Can these wheels break through curing-agent membranes?Yes. The cap-cutter segment is engineered to cut through hardened surface membranes formed by curing compounds.What grinders are these wheels compatible with?Rapida Cup Wheels fit most standard angle grinders and concrete grinders. Check arbor size and machine requirements before use.Why choose Syntec?Syntec produces reliable, contractor-grade tooling designed for consistent grinding performance on demanding surfaces.
