Forney 72757 Wire Cup Brush, Knotted with 5/8-Inch-11 Threaded Arbor, 2-3/4-Inch-by-.020-Inch

Placed it on my porter-cable grinder used it to remove about 100 years worth of paint from cast iron vent cover, all the wires stayed intact and all the paint was gone!

For the price this is probably the best product out there. It is just as good as the Dewalt which is almost double the price. There are definitely better wire cup brushes out there and compared to them it is probably a 3 star product. However those products are over the $20 price point. This particular wire cup brush is very good and like I said previously at the current price point of just under $6 as of March 2016 it is the best option out there.

This knotted cup is decently made for the price. It has been working well in my Bosch right angle grinder removing heavy rust scale from corners and crevices of metal panels. Its one of Forneys lower priced cups imported from China with the red painted body, but it has held up to my use and is still retaining most of its bristles, so I think it was definitely worth what I paid for it here on Amazon.

This one was less expensive and I had concern but this has worked quite well and I would purchase another but this one is holding up just fine.

Last a long time and great value.

Had a Harbor Freight knotted wire cup and did not last very long. Purchased a could of these and used on an angle grinder for days on a metal fence and finished with the wire cup still in decent shape. Would definitely purchase again.

Works well used on some steel before welding cleaned up nicely.

Cheaper than what I was expecting

I have a craftsman angle grinder from 2005ish, it came with one of these and I always thought it was supposed to vibrate like it does, until I purchased this. This appears to be way more balanced, it does the job that I ask of it, and it is affordable!. Will purchase again.

Great wire brush
