The ALLWAY HM1 1-Gallon Helix Paint Mixer and ALLWAY HMQ 2-pack of 1-Quart and 1-Cup Helix Paint Mixers are must-have tools for mixing paints, coatings, epoxies, textures, and adhesives. The heavy-duty HM1 features an original ALLWAY design with a 1/4" hex shaft that fits all 3/8" or larger drills for secure mixing of 1-gallon containers. The patented HMQ model conveniently mixes smaller 1-quart and 1-cup containers with the same secure hex shaft drill connection. Both feature specially designed easy-to-clean polypropylene helix blades that thoroughly and quickly blend materials without introducing extra air bubbles. The helix shape uniformly mixes throughout corners and bottom of containers. Whether you need to mix large batches of paint and texture or precision mixes of epoxies and finishes, ALLWAY's original Helix Paint Mixer attachments help make painting jobs faster, more convenient, and deliver consistent results.
