"Any" 4 isn't something I can tell you about. I can use it on my Makita 4 grinder because it fits the Makita 5. The size of a five-inch disc.
This Forney wire cup brush (72757) is quite abrasive and I would not recommend using it on ceramic or terracotta as it could damage If you need to clean this type of roof, I recommend using a power washer. Thanks for taking the time to ask a
carbon steel bristles of the Forney 72757 wire cup brush are made of steel. You may ask your question here. Thank you.
main problem with this brush and all others that thread on to a 5/8 arbor is that most 15/16ths wrenches are too thick to fit between the nut and the brush. By cutting a piece of 1/4" thick 1-inch plywood, I was able to solve the problem Cutting a fifteen 16th inch slot in one half of a inch of steel bar and welding it to the end of my angle grinder's spanner wrench. It works very well.

My message will be brief and to the point I like it. Is it possible to weld with you? Are you tempted to use a chipping hammer/wire brush to remove slag, or do you hate using them? What is the value of your eye sight to you? I will continue. When it comes to cleaning cups, this cup wire brush and a 4-inch angle grinder are essential It will make life a little easier for you to use this 1/2" angle grinder. My favorite thing about this cup wire brush is that it doesn't sling wires into your arms, chest, etc. like the inline wire brushes!.
My review policy is that I don't normally leave a review until after using a product, and I often forget to do it afterward. In any case, since I ordered another, I'd say it was good in terms of service life. Although the wheel is aggressive (expected from a twisted wire wheel), the main reason I am buying another is that none of the bristles lost their shape. At the end of the brush, the bristles were down to nubs with no sign of shedding. Also good was the stiffness of the bristles and the cup did not flare out too much, and cut consistently when depressed. It provides a decent level of service and has a long life and high quality. In an ideal situation, I would choose a flap disc for severe rust removal or removal of a lot of mill scale, but when dealing with tough rust, or mill scale, a wire cup is exactly what I want. Here is a photo of what the bristles look like after they have worn.
Wire brushes from Dewalt and Forney got messed up during the process of removing paint from a large steel surface. One of the main differences between the two is that you can purchase two of these for the price of one Dewalt. Although the Dewalt did last longer before its performance dropped, at more than twice the price, I prefer to switch out the wire brush when it becomes dull or clogged.
The trailer was rusted on the surface, so we used it to remove it. Sandblasting is much slower and messier than this method. You will not be able to go into all of them. The strands of hair do fly off from time to time. The wires that fly off aren't the only danger, whatever you're working on will spray rust, paint, and scale right off your face at hypersonic speeds. Wear eye protection, however, not just for the wires. Hold onto your grinder, when the grinder hits an edge, it grips and you're on a wild.
In this case, it worked great for scraping paint off of a concrete porch (roughly 45 sq ft). Attaching it to my Makita 4 resulted in no operation. We used it with a 5" angle grinder and it worked perfectly. It is recommended that you wear protective eyewear, gloves, long pants, and long shirts While the majority of the wires did remain intact, a few did fly off and stabbed me like a dart (they do this to everyone). As far as my use on the porch goes, I used it continuously for about 30 minutes, and I suspect roughly 25% of the wire has worn There is 75% left to go). Before hitting the porch with the wire cup, I used a power washer with a pressure of 2500 PSI. However, the cup was able to remove the rest of the paint, while the power washer was able to knock off loose paint.
The Dewalt did not cause me any problems, but the new one is very noisy, causing me to stop every 20 minutes to take a break, and afterwards my hands feel tingly. I also noticed that after only an hour, the twisted ends began unraveling and the tool was wearing out much faster than.
Removing paint with this method is very effective. Get ready to find out how good or how bad those welds from the "welder" under the paint are by grinding them up with an angle grinder. Putting in the effort will be well worth it. Cup brushes usually get the job done better on flat surfaces, but they do the job as well. What stands out most about this process is how relatively little damage is done to metal. The extra material won't be removed during the process, so that's good.
Also when I turned the cup over, I noticed there were severe cracks in the surface. Thanks to my quick awareness, I was able to notice.
