Dico541-778-4 Nyalox Wheel Brush 4-Inch Orange 120 Grit

I was tired of being stabbed by flying needle-like wire bristles while wheel wheeling or doing Jim Carey faces hours after wire brushing and unexpectedly getting poked by a bristle at an inopportune time that ended up in my hair or clothing. If you've used the old fashioned wheeled brushes you know what I'm talkin'bout.My review for all the different 'grits,' of the wheels are the same - the mandrel/drill mount and wheels for a bench mounted grinder. The 'grit' rating doesn't seem to be the same as I'd expected and used with rating sandpaper, but that might be just me.These work as well, if not better because the ends are always fresh and sharp. They're also lasting a lot longer than I'd expected - much longer than wire bristle versions - both the HF cheapies and the big named manufacturer versions that makes you say 'that was how much?' when it fails 'too soon.'They also do better on complex shapes. Examples would be these get into where cross members are riveted to frame rails or other joints and components. They're pretty darn good, but not perfect 100% of the time getting under the lip of the rivets They're also more forgiving when you wheel something you should have really removed. With some practice if you're only doing a section, you can feather the paint, rust, muck being removed so touching it up so you can sell it as rust-free from Arizona, is much more plausible than with wire.There is a safety factor with the Nyalox product that you don't get with the old-fashioned style; because the bristles wear down evenly you don't get to a point where the bristles are like a defensive porcupine pummeling you and your workspace with sharp, usually hot, needles that you'll find months later rusted into the surface of something not even close to where you were working.The other part of the safety factor is they get smaller, and you have to give up and replace them, because you're close to the structure of the wheel or the machine powering it. No more of that one more day like you might do with the old-fashioned kind where you use it until it looks like teeth on a cartoon hillbilly granny.

I got this brush to attempt to clean old mortar off some bricks on the interior of my house, and it did a perfect job. It's gentle enough to not damage the brick but can still take off the extra mortar bits. Ive done a dozen bricks so far in just 15minutes or so and I don't see any signs of wear yet.

Works well. Would like to get a wheel that is wider, but this is good for getting into corners./fine work.

Through no fault of the product AFAIK, it did not solve my problem as I'd hoped. I wanted to remove some old grout film/spots and it didn't affect the grout very much and the Nylon actually marked up some slate tiles I used it on and still it did not remove the material I was trying to remove. Maybe for tougher underlying materials and less tough material to remove it would work better.

I have had this for a couple of weeks and used it a few times. It cleans up old wood very well without removing the ¨character¨ marks. I also used it on old rusty hinges to clean them up a bit without losing the patina.

Used on both metal and wood. Didn’t perform as well on either.

I bought several of these, and they worked great. Once they wore out I bought 4 more. These 4 all fell apart within seconds of being put to use. Dico has moved production to China, and their quality control has gone out the window. Do yourself a favor, take the money you were going to spend on these and flush it down the toilet. This will be just as useful as buying from Dico, and far less aggravating.

I used this wheel to clean the grout in my kitchen tile. I put it in a 12v bosch drill and got to cleaning. With 1/4 cup oxy in 2 cups of water I now have clean grout lines. I am happy with the product and it didn't do any damage to my tile at all.

I used this wheel to clean up the corrosion on my aluminum rims. It worked well without scratching the rims badly. A little aluminum polish after, and they were good as new. Well worth the money.
