The Drywall Mixing Paddle head helps reduce drag and wear on your power drill. The design helps provide splatter-free operation by pulling material down into the center of the mixer head. Smooth paddle edges won't scrape plastic from the mixing bucket. Carbon steel has been plated to help corrosion resistance and easy cleanup. This paddle is best used for drywall joint compound, grout, plaster, thinset, paint and more. Includes mixing attachment.
