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.

The wire wheels are sturdy and do not throw off their material after many uses.

I tried to use it for cleaning welds on stainless. In my cordless drill as soon as the wire bristles touch the shank spins inside and the wire wheel stops. I put 2 tacks on it to see how long it will hold up. Unless you have a welder and are prepared to tack the shank to the wheel they are useless.

Wire tend to fall apart after a few uses

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.

Value for money!

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

Durable, worth it.
