4.5 in. Segmented Diamond Grinding Turbo Cup Wheel for Concrete and Mortar is rated 5.0 out of 5 by 8.
Rated 5 out of 5 by from The Wirlwind 4.5" segmented diamond grinding turbo cup wheel fit on my Dewalt 4.5" angle grinder ... The Wirlwind 4.5" segmented diamond grinding turbo cup wheel fit on my Dewalt 4.5" angle grinder as well as my HF 4.5" angle grinder. It has a moulded nut that can be used to tighten or loosen it to the grinder. The wheel sits higher and a little away from the guard and works well. I used it on fully cured concrete that had a crack in it but also had a ridge on both sides of it. It easily removed the rough spots and the ridge to make a smooth surface, easily cutting through the rocks in the concrete. I could then apply hydraulic cement to fill in the imperfections. There was plenty of dust so wear dust and eye protection. The wheel can also be used to smooth rough spots in mortar. After using the wheel if you apply a thin layer of chain saw oil and put it back in the box it came in this will help prevent rust.

Rated 5 out of 5 by from Excellent grinding wheel! This wheel mounted easily on my Dewalt DWE4011 angle grinder. As shown in the attached picture, the grinder wheel protrudes about 1/2" beyond the blade guard which makes it easy to reach the surface that needs to be ground down. A Dummies for Angle Grinders note... wear gloves and goggles. Also, a long sleeve shirt and pants rather than shorts. Chips can fly and hurt. I just did a quick test, taking the corner off one edge of both a red brick and a concrete block. The wheel is very sharp and the results, which are also shown in the attached pictures were achieved in less 15 seconds for each of the brick and the block. Assuming the wheel stays sharp for a good while, this is a great choice. Of course, only time will tell.

I have a section of concrete that has lifted because of tree roots and created a trip hazard and my snow thrower gets caught on it. I got this grinder so I could grind down the edge of the concrete. It came in a nice unmarked box that will work great to protect it for storage. I soaked down the concrete to try and cut down on dust, got me a cold drink for what I thought would be a long brutal project and started grinding. Within 15 minutes I had ground down the concrete edge about 3/4" along 30 inches of the raised section.

Rated 5 out of 5 by from HIGH GRADE MASONRY WHEEL This Diamond Cup Wheel is ideal for grinding masonry. It will grind off concrete, granite, marble, mortar and many other stone products. I used it to grind off some concrete on a patio where the form joints were. It wasn't that noticeable but had been bugging me for years. It came off easily. A word of caution...The wheel gets very hot. It's made of quality materials and it is balanced well for smooth, vibration free grinding. It has a high diamond concentration for a smooth finish and can be used wet or dry.

Rated 5 out of 5 by from Grind it Out The 4.5 inch Whirlwind Diamond Cup Grinding Wheel is ideal for small or hard to reach masonry smoothing. I installed it on my handheld grinder which was quick and easy. I used it on concrete patio edges where the forms left some undesirable rough spots. Worked well and fast. It can really throw the debris around and make a fair amount of dust so protect yourself and your surroundings. Seems to be made of quality materials so it should last a fairly long time.

I'm prepping my garage concrete floor so I can put down some type of floor paint. I'm still deciding what type to use (epoxy, polyurea, etc.), but what I know from doing it at my previous house is... preparation is key. I needed something to get in the corners so I picked up up this cup wheel and gave it a try in one corner so far. Yep, it's a winner. Although the concrete is relatively new, I had a lot of paint on the concrete from doing the walls. I used a cordless grinder and was able to chew through the paint and surface concrete with no problems. It kicks up a lot of dust, so prepare for that. Overall, this will work just fine for me.

Rated 5 out of 5 by from Cut great on various materials! First thing I notice when opening this blade was it is vacuum brazed and the thin kerf, I started with it cutting a tub surround and plastic tub cut like butter. Next I cut a 4" cast iron vent stack in half, cut very well and the blade still looked good. Tried it on 1/4" plexiglass to cut a couple windows for my garden shed and it cut fast and the blade didn't clog up like other blades I tried. The thin kerf blade preformed like a more expensive one and still looks like it will cut a lot more, for the price of this blade you cant go wrong.

This does a good job of grinding down the cement where self-leveling cement didn't go down very flat. I used this with a 4.5" grinder and a 5" shroud. It worked, but I think that it's recomended to use this with a 4" grinder. There is less dust if you can keep the cement wet, but if you keep the cement wet while you work, then there is a lot of mud to deal with and it gets all gunked up in the shroud. There's no escape from it being a messy job.
