4 Inch Wire Wheel Cup Brush Set, Coarse Twisted Knotted Wire Wheel for Angle Grinder, 5/8 Inch-11 Threaded Arbor, SHITIME 0.020 Carbon Steel Wire Brush for Grinder, Deep Sanding Heavy Rust, Paint.

Pros: This is a good set of inexpensive wire wheels. You get 4 wire wheels 2 flat and 2 cup all 4 screw on to a standard angle grinder and seem to hold up well and take rust and paint off of the material you are using them on. They do throw off some of the wire pieces however I do not think there are any out there that do not throw some wire when in use. The metal rings seem to plenty strong enough to avoid any catastrophic failures. Overall: For the price you really can not go wrong with this wire wheel set. They hold up well for the price. I can recommend them.

Wires seem to fly out of first wheel I used. Havent checked the others yet.

I got done what I needed to, (getting a motorcycle frame to bare metal) but the cup attachment started sheding its bristles everywhere near the end of the one project. ABSOLUTELY REQUIRES FULL PPE (PERSONAL PROTECTIVE EQUIPMENT) TO USE. Was only good for one job.

Worked fine. But I had wire stands fling off and impaling me at times.

Gets the job done when removing rust. These wire brushes are rated at 12,500 RPM so just make sure your grinder is rated for their use. I have the Metabo angle grinder and it’s rated at 11,500. My maintenance shop has quit a few of the Milwaukee angle grinders and they are rated at 11,000 RPM. That’s the corded ones. I didn’t check our cordless grinders but they should be below that. I would guess a couple thousand but you should always check. Never use a grinder above the RPM rating and if you do you will find out real quick why you shouldn’t. Lol. Either way they work great and I would definitely recommend this set.

All 4 of these brushes seems to be doing a nice job while holding up well. Removing rust from trailer frame and they all have a different purpose and use on this project which they are all meeting expectations for the price. Starting to feel some vibration as they get used more so hope that does get to the point of off balance enough that I cant use them anymore. If that happens prematurely I will update my post to reflect that as my rating will fall. As for now I would recommend this set

These work great for getting off rust. They seem to be well made. 5/8 nut makes it easy to quickly swap one out for another. Plus with the variety here, you should be able to take care of whatever you need to and get every angle.

I tried these on my Milwaukee M18 angle grinder and these bad boys take the rust off of my skid steer bucket very quickly. I did notice only a couple of wires that came out of the wheel. Not to bad so far I would say. Defiantly wear a mask and safety glasses when working with these wheels. Rust was flying off at a quick rate so use caution with these. I did not get a chance to try out the brass one yet but it is built the same way as the other wheels so it should also hold up fine. Now I have to try these out on other projects I have around home. A 5 star so far for me. Thanks for reading.

I am a big fan of 3out of the 4 wire brushes on this set. The quality and workmanship of the three brushes are definitely very good. The fourth brush, the brass coated brass colored brush I am not a big fan! Because they are using a wire wheel with two dissimilar metals which is basically corrosion waiting to happen. This set would have been much better if they provided another carbon steel brush or a pure brush wire wheel. The brass wire wheel could be used for cleaning brass fittings, but using the brass coated carbon steel wire wheel on the brass fittings is not advisable because you may inadvertently embed carbon steel particles into your brass fittings which could induce corrosion in your brass fittings. If you need to clean brass or copper fittings buy a different set of wire wheels.

I like that the pack comes with 4 different style wire wheels. I tend to use the twisted wire wheels the most, but its nice to have the others. I used all of them to remove rust and old paint off a delta unisaw Im restoring and the wheels worked great. Good variety of shapes to get into corners. I did some really aggressive work on some panels and found that the wires starts to really fly off these wheels if you get aggressive with them. I think all wire wheels do this, but I think these guys really started to come off quickly. They lasted long enough for my project, and look like they will probably last at least a few more long days of grinding. They fit standard grinders and overall, they are good value, just make sure to protect your arms and wear your safety glasses.
