Ultracut GPM Series

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.

Question : How long does it last compared with a standard abrasive cut off wheel?

Answer : It is subjective depending on the application. However the general indication of the Ultracut GPM Series is that it may last up to 50 to 60 times more than that of a standard abrasive cut off wheel. Conservatively it should last 30 to 40 times more than a standard abrasive cut-off wheel. With this said, you can save downtime from the disc changes, thus adding user-convenience, without wrenches and abrasive cut-off wheel inventory.

Question : Can I use it with water to eliminate dust?

Answer : Yes you can use Ultracut GPM Series with water to reduce dust and also improve the performance and life of the tool.

Question : Can I cut very hard materials such as a granite slab or a porcelain tile?

Answer : Normally sintered metal bond diamond blades have more of an advantage cutting granite and porcelain over vacuum brazed diamond blades, so we don’t recommend using the Ultracut APR Series blade for granite or porcelain. If you have to cut them, we recommend cutting them with water to cool the cutting edge.

Question : Can a Quad Adapter fit on the Ultracut GPM Series to make a flush cut?

Answer : No. You cannot use a Quad Adapter on the Ultracut GPM Series. However, we do offer the Ultracut APR Series for flush cutting applications.

Question : Can I get double the life with the Ultracut GPM Series since it is a bi-directional blade?

Answer : No. Ultracut GPM Series will perform at its best in either direction for a long time when it is new. However when you flip the blade, you are utilizing the remaining cutting edges of diamond that were not exposed to the application so that you can extend the life but it will not double the life of the blade.

Question : What kind of tool can I use the Ultracut GPM Series on?

Answer : Ultracut GPM Series fits on most popular angle grinders, circular saws, worm drive saws, metal cutting saws and stone cutters.

Question : Can I use Ultracut GPM Series on a cordless grinder?

Answer : Yes. However, since you can increase the performance of the blade with a stronger power tool at the highest rpm, we recommend using the Ultracut GPM Series on an industrial quality corded angle grinder. If you must use it on a cordless grinder, please run it at the highest rpm and let the blade cut the materials at its own pace.

Question : Can I fit a 4” Ultracut GPM Series on a pneumatic extended cut-off saw?

Answer : No. The 4” Ultracut GPM Series comes with a 20mm arbor. However, Alpha® offers the Ultracut ABM Series that comes with a 3/8” suitable for pneumatic extended cut-off saws. Alpha® also offers 3” x 3/8” Ultracut ABM for 3” pneumatic cut-off tools.
