Megatron 4-Inch Diamond Cup Grinding Removing Disc Wheel for Concrete, Paint, Epoxy, Glue and Mastic with Advanced CDB Technology (Megatron 4-Inch) Review

Whoever invented this disc is a genius. Had to remove 3 coats of garage epoxy in a 2 car garage. Although it produces a lot of dust as expected, I was able to remove it easily and the drive still looks brand new.

Forget the cool patterns etc. Sure the edges add to the cutting action but this guy reminds me of the cluster circle with multiple dots, who i love aggressive when needed (at the right speed/pressure), leaving a nice scratch pattern when needed (lighter touch with faster buffing speed). Generally, Santa can send me a batch of them.

Bought this sanding disc for removing paint on the front and back porches. Chewed through 12 coats of thick paint on the porch. Installed a Makita in my pruning tool and bought a shroud with a vacuum nozzle. Was able to recover 99% of the paint chips in my HEPA vacuum. Done with the second porch and it's still edgy! Great tool!

Amazing Product! It's worth the money. This leveling disc quickly did the job of 45 years of paint building on my 6ft x 12ft porch. Completely removed 7 or 8 layers of paint and covered the concrete with a perfectly smooth surface. It is expected that I will have to buy a second one to work in fishing. That is unnecessary. Using the same coffee grinder, I can easily make another pillow of the same size. Very impressive!

Megatron's wheel worked very well initially. Removed the paint and taped off the concrete like it wasn't even there. It started to fade after 42 sqm. foot and after 84 sq.m. Feet smeared paint. For almost 50€ I would have expected a higher quality product. I've definitely returned this bike and am trying a few others. I may have come across a broken wheel, but I didn't want to risk swapping it out for the same part without knowing if it was one.

These cup wheels are commonly used as the first step in edge grinding in almost any case requiring surface preparation, exposing aggregate, removing adhesives, paint, coatings, putty, etc. Excellent for extremely hard concrete because they can do not freeze. They break through soft concrete even quicker, but I found it wears them out much quicker. They have replaced most other cup wheels as they are more efficient than other technologies, although I use many higher grit ceramic cup wheels for…

I used this to clean and smooth out old glue on laminate tile from a bathroom floor in preparation for an epoxy floor. Did 40 square feet in about an hour, was fairly easy to control and produced a lot of dust. I wasn't planning to pre-order a dust cover for my grinder, so I used a dust mask and an exhaust fan in the window, which really helped. Picture between sanding and epoxy unfortunately but it was very clean but I can see the shadows of the tile after applying the epoxy. Maybe I could get

I have experience with grinding cups. I've used some of the cheaper Revain cups for grinding concrete. I wanted to try this device as the reviews were good and since it's three times the price of some of the cheaper mugs I've jaded I figured it should work great. aggressive, but after sanding a 4x4 section of basement floor (to remove a layer of paint), the sander dulled and switched from sanding to buffing. But just to be sure, I threw in one of my old, dull $12 mugs, and it eroded the paint…

I have a set of concrete stairs that have cracked due to settlement and have been repeatedly painted with fairly tough facade paint. In order to paint them I had to remove most of the paint and remove past putty/repairs. I put this wheel on my often used Hitachi angle grinder and this item did the job. What is good. It was so aggressive and grabbed the surface of the concrete < I had to lightly touch it while having less of an impact on the paint which seemed to be melting but clung…
