Designed for small jobs and hard to reach spaces, this patented passive planetary operation creates the perfect profile for new coatings. Built rental tough, the 5274 is easy to operate and low maintenance. The versatility of the 5274 is derived from its quick-change magnetic tooling to remove thin-set, coatings, adhesives, remove high spots, and prepare concrete and overlays for coatings.
