The Groz Paint Mixers for material blending. Crafted with quality, our mixers are ideal for seamlessly mixing paint and low-density materials. Manufactured from a sturdy 5/16" hexagonal shaft with fluted construction, The Groz Paint Mixers boast an attractive red powder-coated finish, ensuring prolonged rust protection. To achieve the perfect consistency, place the mixer in the material container, gently work around the edges, and continue until the material reaches the desired state. For coarse materials, reverse the drill's direction. The Groz Paint Mixers are optimized for use with variable speed reversible drills (400–600 watts, 200–700 RPM), offering an unparalleled blending experience.
