This exclusive and unique blade cuts stubborn materials that diamond or abrasive blades can’t, such as joint sealant materials, caulking, rubber or wood. Features chunks of carbide placed in a matrix that shreds joint sealant and caulking materials. Used with an angle grinder, it does in minutes what normally takes hours using conventional hand removal methods. Safely “cubes” even the softest sealant materials without burning the material or “gumming up”.
