Drill Brush is a small business based in New York State that makes cleaning brushes that attach to drills. It was started in 2007 by a former electrician who suffered from Carpal Tunnel Syndrome and needed a way to clean without causing him harm.
Promising review: “These are great! I use the large one to give the bowl a cleaning. A variable speed drill (needed) makes quick and short work as well. They have other brushes for other applications that I will order as needed. Very affordable, well made and will get many uses due to durability.” —Michael R.
