Rapida Cup Wheel | Syntec Diamond Tools
Introducing the Rapida Cup Wheel
Powerful grinding performance for extremely hard concrete.
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-trowelled 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 can struggle 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 quickly enough to expose new diamond edges. Using the correct bond is essential for efficient grinding, improved productivity and avoiding premature wear.

Frequently Asked Questions
What are Rapida Cup Wheels used for?
They are designed for grinding extremely hard concrete surfaces, especially floors strengthened with curing agents or finished with dense, smooth-trowelled surfaces.
Why do diamonds glaze on hard concrete?
Glazing occurs when the bond is too hard and does not wear away quickly enough to expose fresh diamonds. The Rapida’s soft bond helps maintain an aggressive and consistent cut.
Can the Rapida break through curing-agent membranes?
Yes. Its cap-cutter segment is engineered to help cut through hardened surface membranes formed by concrete-curing compounds.
What grinders are Rapida Cup Wheels compatible with?
The 5-inch Rapida Cup Wheel has a 7/8-inch bore. Always check the arbor size, guarding and operating requirements of your grinder before use.
