Product Introduction
The spiral turbo cup wheels have segments angled at approximately 45º in toward center of wheel. This allows the wheel to ride flatter on the concrete surface, eliminating gouging problems associated with the conventional single and double row wheels. Cup wheels with more segments are for heavy removal. Premium grades provide longer life, faster grinding speed, and greater range of application.

Key Inspection Steps
There are 2 key inspections steps on concrete grinding wheels before delivery: the balance test, and bore hole test. If the cup wheels are not balanced well, it will jump during operation; The bore size will be smaller after painting, if not do the bore size test, it will be difficult to fit the cup wheel to angle grinder.
