Rocaris 6 Pack Wire Wheel Cup Brush, 3 & 4 Inch Twisted Knotted & Coarse Crimped Cup Brush for Angle Grinders, 5/8 -11 Inch Threaded Arbor

The work great, lots of options for the cups. Threaded to my grinder with no issues. Just be careful taking out of the box as they are all compressed into a tiny box, and you have to grab a sharp wire edge to get them out.

This is a good variety of grinding brushes. They fit my angle grinder just fine and seem to hold up well.

I have been using grinders, cup wheel wire brushes, and flat wire brushes for a while. I cleaned up an old iron table and chairs this summer with some and am always looking for bargains. This set is ok - not as sturdy as most I have used, but get the job done. Be careful on the non-twisted ones as the wires fly out and they can injure you - I stopped using before I got a hole in me. The twisted brushes held together fairly well and had no issues, but the straight wire cup had wires flying out of it fairly quick - and I was just trying to loosen some varnish on a wood top to remove it. When I saw the wire stuck in the wood and stopped, I also saw more wires on the way out - see the pic. I will continue to use the twisted brushes as they held together, but the straight wire ones are going in the trash. I have several of those that are better quality and dont come apart.

I got these wire wheels for my husband. He used them on a wood project he was working on, and he reported that they were great at grinding away mold spots in the wood. Be warned though, my husband had to wear long sleeves, pants, and eye protection when working with these. As he was grinding the wood, the wires in the wheels started to fly off in all different directions, creating shrapnel that he had to guard his body against. We are not sure if this is because he was using them on wood and not metal, or if it is something that would happen no matter what you used them on. Since I cannot speak to how well they hold up when used on metal, I will simply say I would not use these wire wheels on wood.

These are a bargain and laying them side by side with name brands, I could not tell the difference. They stripped rust and paint off just fine and what a deal when one from a major retail store can cost the price of this entire set. The threads were cut clean and screwed right onto my side-angle grinder without any effort. The thread on the brushes is the standard 5/8 x 11 on most side-angle grinders. Tightened with a wrench and started removing paint and rust. Great Deal!

Good fit to my Grinder. Attachment point is a steel nut that went on perfectly and does have access to get to it with a wrench to loosen it when finished. Twists look OK and will hopefully hold up for several uses. This set has four twisted and two straight wire wheels.

Solid assortment of grinder wheels for rust removal and metal paint stripping. They fit great on my Bauer 4-1/2 in 7A angle grinder with 5/8 arbor. They stay secure on the grinder and theres no vibration issues at max RPM. Quality is about on par with what you would expect from Harbor Freight. They worked out well stripping rust/paint from steel patio furniture that I repainted. I tend to use the twisted knot wheels the most, and my only complaint is that the diameter on these is too small. Larger twisted knot wheels can get into nooks & crannies a lot easier, and last you considerably longer.

This set comes with two 3 knotted wire cup brushes, one 3 crimped wire cup brush, two 4 knotted wire wheel brushes, and one 4 crimped wire wheel brush. They all have a 5/8-11 threaded shank. The knotted brushes are more aggressive, and the crimped wire brushes are better for irregular service, so it is nice to have a good selection on hand. I use them on a cordless 4-1/2 Milwaukee 18V grinder and a corded Dewalt 4-1/2 grinder. They work great for cleaning rust or old paint off metal surfaces. I recently restored 40-year-old livestock trailer rims. They were a mess, and these brushes cleaned the rims up well enough for priming and painting.

Good wheels, worked well.

Care full when you use this for the first time. Some of the steel piece were lose and went flying in the air. Use a face shield for sure and gloves these are sharp. Pictures to follow.
