OCR 4" Concrete Turbo Diamond Grinding Cup Wheel Three Row Turbo Cup Disc Grinder for Angle Grinder 12 Segs Heavy Duty(Blue 12segs B)

It appears that there are four different products here, but no explanation is provided as to how they differ. In spite of this, if the pictures are to be believed, it appears that the diamond segments on the "A" disk are significantly smaller than those on the "B" disk. My guess is that the diamond grit may have corresponding disparities in coarseness, but this is just my speculation. The yellow wheels and blue wheels do not appear to differ in any discernible way. I do not believe that the color differences on the wheel are just to satisfy individual tastes in appearance.

The short answer was "no", but they could cut concrete for $250+. Grinding wheels for angle grinders were referred to me by someone and I had no idea a four-inch angle grinder could grind concrete. After searching around on Amazon, I found this one and found it to be a good deal. It was reported that someone on here had issues mounting it, and I can see how it might be problematic depending on how it is configured. Because of the cone shape of the wheel, it is difficult to get the nut on the spindle of the grinder. Using a cheap Harbor Freight grinder, I was able to get the nut on but the wheel is sloped so it tightened around the edges. The wheel was secure, but did not clamp the flat part of the part like a traditional cutting/grinding wheel would. While grinding the walkway, it took me about an hour and a half to grind 2 cracks that were about 2 inches wide There was a lot less wheel wear on the wheel than I expected, as well as the material moved quicker than I anticipated. The package design made me laugh. I am very happy with the purchase and even more happy that it came in Chinese.

It's a no-brainer A lot of people have been expressing their appreciation for the Although there were many different ones for sale on the site, I chose this one for the price and for the basic reason that it looked secure. I'll let you watch my video to see how quickly this thing ate the slate table top I had to work with, grinding it down almost half an inch in 30 seconds. This attachment does not allow you to easily grind even a soft stone to perfection, but it is a really good I've also used this grinder for an initial treatment on rough barn wood, and it is working well for me. In this way, I have a lot of fun with it.

It has a solid build, and for the price it is an excellent buy! I now have a perfect surface to lay tile with mortar. It took me about 3 hours to lay the terracotta tile. I used a 4, which caused a lot of mess, but at least that's not my fault. Make sure you wear all the necessary safety equipment, especially a face mask, and seal off the area where you are working to contain the dust. In addition, install fans so the dust can be sucked out of the window.

A good little grinder for being an unknown player. Does a good job for being an unknown player. had never heard of the company before I discovered this product on Amazon]. As a result, we had to obtain one of these FIX IT Notices to remedy an issue from our city office. They were mailed out As a consequence, we first attempted to use those $2 to $4 bills and failed A type of grinding wheel for masonry and cement. I wish I had known what a waste of money that was. The first time I tried a cupping wheel like this, I wouldn't have bought it because I didn't know how much better it works. There is a night and day difference in how this diamond cupping wheel works from what a diamond wheel does. He is one of us The masonry wheel works for $2 or $3 at a low cost. In contrast to the concrete and dust, the uneven edges of the wheel were truly something to behold when it went to work on them. As the cupping wheel flies over the area that needs to be reduced, I reduce it by a factor of ten. This was a straightforward job we completed. We produced a nice, flat, clean looking concrete junction between the two concrete segments of our IMPORTANT NOTE When I tried to purchase products from local businesses, the selection of products and the pricing were just too expensive. Whenever I went to Home Depot, I saw only well known brands such as Bosch, Dewalt, and Milwaukee's cupping wheels grinders. But the prices of those also began at $50 and went up from there, making them a "premium" product as well. The pros are Please note - Acupressure cupping wheels that are far less expensive than brand name cupping wheels - Even when working with cement and/or concrete, it seems to last quite a long time - A mixed bag of emotions greeted me at the airport. The items were supposed to be ready for picking up by the end of the week, but were told it would take a few days longer. Ultimately, it arrived two days before the date indicated in the "will be late" message. I really appreciated that it came like a day later than initially indicated, in time for me to need it, so it was no problem for me The cons are Please note - The surface of the sheet is prone to wear down faster if you pound it quite hard. Please note - There have been a lot of comments online about how these cupping wheels and utilizing them on concrete and cement will produce quite a bit of dust. When I used it, we were outside and had a nice strong wind blowing. The dust output from the grinder is upwind so we set it up there. Apparently, both inside and outside of a building would benefit from the use of vacuum systems for dust. *- Previously, when we helped a relative install a new tile floor in the kitchen, we used a 9" scraper blade with a large handle. I was involved in a difficult process that took a long time. When I first introduced diamond cupping wheels to my classes those many years ago, I did not know what they were. I look forward to re-visiting it next time If you have old tile, adhesive, grout, etc. , use a cupping wheel like this to remove it.
