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

Fits my old tool-shop angle grinder and does a decent job cleaning up rust. They don't last forever, and the wires do fall out and wear over time, so I guess there is room for improvement, but overall, I am happy with the performance.

This is great wire brush. I'm using it to remove paint and rust on a vehicle frame and this cup does the trick, blasts through the muck quick and easy.The cup maintains its shape well, there's some spread at high speeds and high pressure but overall it's still awesome. The strands keep their twist and I've not noticed any major loss of wire bits. The cost can't be beat either, far less than big brand cups and no loss of quality, I know because I've used those big brand devices.

I used it to remove the finish from a metal table, striped it to bare metal in no time. Toughest wire wheel I've ever seen.

Worked good grinding thick paint off the surface of concrete blocks. Prepping to seal the blocks and wanted to rough up the paint and get rid of it in some places. The wheels worked good and were durable. I bought 4 for a room that is 40' by 25'. Have three worn down to 1/4 inch or less and one still unopened for the next project.

I'm refurbishing a 60 year old drill press. I needed something to help remove the old paint, rust, and accumulated grime. This does a fantastic job. Used in a .5 inch drill it quickly got down to the bare metal. Best of all it is very good about retaining the bristles. Other wire wheels that I've used have been prone to losing bristles and wearing down quickly to the extent that they can be unusable. That is not only frustrating but dangerous when the bristles are lost at speed. This has resolved those problems. Highly recommended.

Problem with order. Customer Service made right in record time.

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. It's one of Forney's 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.

Used to remove rust off a wheelbarrow before repainting. Worked great - I didn't notice any loose wires flying off. Used with my Ryobi cordless angle grinder. I don't look forward to needing it again (because thats a dumb job to deal with!) but I expect it'll work great again when I pull it from the tool box.
