This is the SurfacePro Turbo diamond cup wheel that General Equipment builds for its SG7 edge grinder. It is a 7-inch steel cup wheel carrying twelve combination matrix bond diamond segments, made for spot grinding, small area work, and getting into edges where a walk-behind grinder cannot reach. Concrete contractors use it for grinding green and cured concrete and for taking thinset, glue and epoxy off a slab. Multiple cooling holes through the cup help keep the segments from overheating during extended grinding.

Fits
General Equipment lists this cup wheel for the SG7 SurfacePro edge grinder, and it is the cup wheel called out in the SG7's own parts and accessories list. The universal 5/8-11 arbor thread is an industry standard mount, and General Equipment describes the wheel as suitable for the SG7 and other competitive edge grinders. That is the manufacturer's wording, and it is deliberately general, so confirm arbor thread, cup diameter and maximum speed against your own machine's specification before fitting it to anything other than an SG7.
Dry use only
General Equipment specifies this cup wheel for dry use only, in non-hazardous locations. The SG7 has a 2-inch dust port, so pair the grinder with appropriate dust collection when working dry. Note that while the SG7 grinder itself is rated for concrete and asphalt, the manufacturer's stated surface applications for this cup wheel are concrete based: grinding green and cured concrete, and removing thinsets, glues and epoxies from concrete.
