The RSP Twister Non-Threaded Grinding Cup Wheel Supreme compliments the polishing process. From countertops to edge work, the Twister cup wheel compliments the first 2 to 3 steps in the polishing process.

With an 18 seg configuration, available in 3 grit sizes, it can give the freedom of an aggressive grind while still delivering a smooth finish.

Twister cups have a flat core allowing more area to long segments. This helps reduce the risk of gouging the floor and circle marks that are often associated with cup wheels. Available in a range of grit sizes they are popular for both concrete preparation and early polishing steps.
