The Sawtec Crac-Vac cuts to a depth of 11⁄8 inch and is ideal for cleanout of random cracks and joints in concrete. It controls dust generated during routing out of cracks and joints in preparation for the application of repair compounds. The Crac-Vac has a patented vacuum housing with internal impeller fan that routes the dust to a reusable dust collection bag. When mounted on a dolly, it can be used for straight-line joint cleanout work, or for cutting artificial grout lines for decorative concrete applications.
