Users of this Jiffy Mixer LM, paint mixer blade, have the option of permanently affixing it to any electric power tool with a 1/4" chuck. The LM blade is made of 304 polished steel and measures 10.25" long to reach the bottom of most 2 gallon paint containers. This mixer blade is rated for a small job or pint size paint can. However, the most efficient mixing will be performed with a power tool generating 450-750 rpm.
