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.

Ill admit I was surprised when I opened this box and saw these brushes. I am impressed. These are heavy duty workhorse brushes. The twisted wire brushes are so tight I was unable to move the bristles with my fingers. They fit my 4.5 angle grinder just fine.

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.

These are some massive, heavy duty wire wheel brushes. They will certainly do the job of removing rust and corrosion from anywhere you can reach. They are great! The only bad thing is when pieces come flying off with the high RPMs of an angle grinder. So make sure youre wearing safety glasses and gloves and have complete coverage of all potentially exposed skin.

Needed a most have Im a beginner welder

Great brushes. I completely sanded down my entire flatbed and went through 2 brushes. I’ll definitely be buying these again. Great price!

Ive gone through a few of these types of wire wheels. I went through a phase of finding old USA bench vises and restoring them. This usually involved using my angle grinder and wire wheels to strip off old rust and hardened dried grease. This seems to be an all inclusive set and includes something Ive not used, a brass brush. The RPMs printed on the back show to be rated for any angle grinder. One thing of note while using these is that the wire bristles while in use will come off and fly like bullets. When Im lazy and work with no shirt on, these will stick in your skin and sometimes draw blood. When I was wearing a leather apron, they will stick into the apron. Whatever you decide to do make sure you WEAR SAFETY GLASSES. You only get one set of eyes.

These wire brush wheels are excellent. They are aggressive and do a terrific job of cleaning metal up prior to welding. I even use them to clean up my welds after the fact. They do a good surface prep job and last quite a while. I have not been able to wear one out yet despite all my efforts. Im thinking of getting a another angle grinder just so I can keep the cup on hand along with the disc.

I picked up the set mostly to use to clean up a boat trailer before I repainted it. It definitely held up under extreme use and pressure for several hours! Boat trailer now looks great and all the rust is gone. Cleaned up very quickly using this aggressive wheel and made for quick work for prime and paint. Highly recommend and a great value!

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

I liked this product because of its design. The built in hexagon nut makes for easy changing of wire wheels. With this 4 pack I was able to get even angle I needed with at least one pad. I use this quite a bit and they are just as sturdy as the day I got them. I have no complaints and very happy I ordered this when I did because it came in clutch a few weeks back getting the rust off the heads of steel well cover. Used the gold colored wheel to clean heads of bolt off so 18 mm fit on correctly.
