For grinding down a high spot in a slab or stripping coating off a garage floor, this is a Ridgid 4.5 inch turbo cup wheel: a diamond grinding wheel with 14 segments on a steel core. It threads onto small angle grinders with a 5/8-11 arbor, and the maker lists it for shaping, grinding and polishing concrete, wet or dry. A concrete finisher, a flooring installer or a homeowner prepping a basement floor would get use from it.
- Brand: Ridgid
- Diameter: 4.5 in.
- Segments: 14 diamond segments
- Core: steel
- Arbor: 5/8-11 threaded
Our singles come from retailer return and overstock loads, so this can be new, open-box or a customer return, the package may be worn, and it’s sold as-is unless stated otherwise. Look over a returned cup wheel for chipped or worn-down segments and damaged arbor threads, which tell you it has already been used. [email protected] will answer condition questions before you buy.
