Star Cup - 5" Very Soft Bond, 6 Grit 7/8"-5/8" - Non-Threaded

Star cups have an ideal design for grinding floors fast which is a great asset when doing concrete surface preparation. Especially when working with tough trowelled surfaces, these cups work efficiently to break through the hard cap, leaving a smoother finish.

Consider the geometric shape of a grinding cup wheel as one of the most important factors that determine its grinding performance. The Star shape is a design that improves the capacity of grinding, cutting removal, and friction reduction. Therefore, the grinding tool’s unique shape results in a greater range of improvements. For instance, these include reducing energy consumption and better overall performance.
