Electric Angle Grinder – AC Power For a Consistent Supply
There are over 3 million registered electric angle grinder importers in the United States. The reason the number is so high is because most of these units are made overseas. Like most consumer goods, the manufacturing of even American brand name goods is no longer made in America.

Another advantage is there is no exhaust air coming out and the dust is easier to control.
