The HYDE® StirWhip™ mixes even heavy materials without overworking your drill. Its nylon “fingers” flex to fit through 5-gallon pour spouts, and reach into corners for more complete mixing and maximum lift from the bottom of containers. Low drag requires less power. Excellent for paint, compound, concrete, grout, thinset, epoxies, lacquers, adhesives and sealants. 3/8" steel hex shaft for use with 500-1500 rpm drills and 1 to 5-gallon containers. Cleans up in seconds. Watch the video.
