Review on Enhance Your Drilling Performance with Century Drill Tool 77221 Abrasive by Jonathan Suarez

I've tried every available cleaner for an old plastic tub (including magic erasers). The stains could not be removed. I then bought it and hooked it up to my drill press. Use some comet, water and this brush on my drill bit and voila the stains are gone. Couldn't believe it. Years of dirt are removed in minutes. Be careful, too much time in one place can and will erase more than you want. I also wish the drill was longer. It would require less bending and reaching.
