Hanson Plunge Mixers are top of the line heavy-duty mixers ideal for mixing glazes, plaster fiberglass, resins, plastic compounds, mortar, cements, foundry core mixes, molding sands, and asphalt sealers. They are meant to be attached to a hand drill. Capable of mixing dry powder as well as wet glaze. The blade design mixes thoroughly with a minimum of air entrapment. The teeth help work your way to the bottom of the thickest mixes. Made from zinc-aluminum alloy, cast and tumbled smooth with a no-burr finish for easy clean up. This kit includes three plunge mixers. The 001, 002, and 003 are all brought together in one price. These mixers can mix materials in a pint all the way up to about a three gallon container.
