The 12 Turbo Segmented cup wheels were designed to help reduce the circle marks and gouging that row style cup wheels created. Having less segments and less diamond surface area makes them more aggressive than the 18 or 24 seg version. They are the most popular option for concrete prep.
The Runyon Surface Prep 7″ Non-Threaded 12 Segment Arrow Concrete Grinding Cup Wheel is specially designed to grind quickly on concrete and masonry surfaces while keeping up with quality efficiency. It’s ideal for removing thin set, thin mill glues, thin mil epoxies and urethanes.
