Ideal for caulk removal, the manufacturer’s caulking blades are uniquely shaped carbide-tipped blades used with the AS170 brick and mortar saw. While simultaneously grinding both sides of the expansion joint, the blade removes caulk, leaving behind a clean surface ready for recaulking. It replaces traditional removal methods, and saves time by reducing more traditional four-step processes into one. The carbide and steel blades are available in 1/2-, 1-, and 2-in. sizes.
