Alpha Tools' Ecogrinder is a virtually dust-free high performance grinder designed for continuous production. The slide cover allows the grinding wheel to grind against walls while the Spring Loaded Flange Assembly offers smooth grinding without any adjustment. The Ecogrinder eliminates the need for a vacuum and is a good tool for countertops. A Dust Carriage Backpack is now available for convenient movement of the dust collection bag. It either rolls behind the Ecogrinder or can be worn as a backpack.
