FPPO 4PCS 3 Inch Stainless Steel Wire Wheel Brushes Kit for Drill with 1/4-Inch Shank,Wire Wheels for Power-Operated Grinders

These kept coming out of my angle head pneumatic cutoff tool I was using for some light small wire wheel paint removal. I micd them and they appear to be slightly under 6mm dia. For reference, 1/4 inch = 6.35 mm. They were sufficiently undersized that my collet couldnt hang onto them such that after 30-60 seconds of use, theyd spin airborne across my shop. Probably a supply chain shortage in China where 6mm is common and 1/4 is not...or was in short supply and 6mm was close enough. My cutoff is a cheapie, and the collet was bottoming out (decades of use, too). Be warned.

Value for the amount of wire wheels real good deal. Not for tough jobs. Wheel becomes loose from the shank and slips. Overall if you are careful and delicate, does the job.

I use these to clean 304L stainless steel after I weld it. If you dont use a stainless steel brush to clean the welds there is a high chance that it will start to rust.

Bought a return (used?) set for reduced price. So, better price and appear to be as good and work well as the ones Ive gotten from other places.

Durable, worth it.

Low quality. The bristles are already damaged, perhaps in shipping. Not happy at all.

It worked well cleaning old copper.

Just to warn you the shank is under 1/4 by .019 and would not work in my 1/4 collet. It looks good should work good for a drill.

Wire tend to fall apart after a few uses

Nice set for the price . Works well.
