The mixer/stirring rod fits into most handheld electric drills to mix paint and various liquids.
The paint mixer is ideal for:
Mixing small batches of concrete.
Mixing drywall patch
Attach the mixer to a power drill to mix nearly any substance to your desired consistancy.
The ideal mixing speed is approximately 600 rpm.
Take care not to stir/mix drywall patch too much. It will aerate the mixture and cause it to dry too quickly.
