Drywall mixing paddle have been designed to reduce drag and wear on your power drill. Unique design also provides splatter-free operation by pulling material down into the center of the mixer head, rather than throwing it against the side of the bucket. Smooth paddle edges won’t scrape plastic from the surface of the mixing bucket. Carbon steel has been plated for corrosion resistance and easy cleanup. Outstanding performance for drywall joint compound, grout, mortar, plaster, paint and more. A wide range of sizes (120, 135, 180 mm) and fasteners (M14 and hexagonal) will allow you to adjust the appropriate mixing paddle to your power drill or paddle mixer.
