These have a hex shank, so These attach to any drill or impact driver. Makes cleaning surfaces easy. Comes well packed. Good quality.

I tried these brushes out on a neglected area of a tile shower. I used OxiClean that was dampened with some water as a cleaning agent. This was a task probably more appropriate for the medium or heavy bristles, but the soft bristled brushes did a nice job. Just need to stick with it, sure and steady. The still photo shows what the area looked like after the brushed area was flushed with clean water.

Be careful not to overheat your drill, as this is an unusual task for most drills. These brushes are well made and there is a good selection in the package. Drill brushes sure beats old fashioned "elbow grease." This brush set can save you from wrist injuries from repeated motion. Worth the price.

These are a must have in all firmness's! These are so many ways to use these from house, car boat!

A really good way to put a handy tool to more uses. Got his to use with my cordless drill, it fits and works fine. The bristles aren't too rough, so it's good to use with a powdered abrasive cleaner. An easier way to get a lot of scrubbing done without a lot of extra physical effort. I'm pleased with it.

I use these with soft scrub to clean the bath tub about once a month. They work well and much cheaper than the as seen on TV versions.
