The Alpha® Ultracut GPM Series is made for building contractors and fabricators who work with metal and composite materials. The GPM Series blade fits on most popular hand-held electric power tools such as angle grinders, stone cutters, circular saws and worm-drive saws for the demanding metal applications. Just name a few, roofers can cut galvanized steel roofing sheets and corrugated granite granule coated metal roof tile, easily with a worm-drive saw without worrying about carbide tip loss, compression marks and burning of paint. Since the Alpha® Ultracut maintains excellent cutting performance at the maximum cutting depth throughout its life, iron workers and underwater welders will enjoy using Ultracut on their choice of tool for most of their cutting applications without having to change the blade. This will save a lot of time and money. The Ultracut GPM Series cuts angle iron, pipe, electrical conduit, re-bar, metal stud, structural metal, sheet metal, grid, and stainless steel along with wood, plastics, composite materials, marble, limestone, engineered stone/quartz surfaces, masonry and concrete. The Alpha® Ultracut GPM Series is the ultimate diamond blade for the most demanding applications.
