Erduoduo 2 Pack 4 Inch Diamond Cup Grinding Wheel 12 Segs Heavy Duty Angle Grinder Wheels for Angle Grinder

These grinder discs work as needed, but do not last long when used in hard building materials.

when i orderd the grinding wheels i forgot to measure the shaft on my makita grinder, so the holes in the grinder disc are a bit large. am trying to find a way to make the disc work with my grinder which has a shaft of .615 diameter and the holes in the grinding disc measure .80 diameter.

Good Product

I purchased these grinding cups to remove about 100 sq ft of tile mortar from my concrete basement floor. I use these cups on a 4 1/2 inch black and decker corded angle grinder with a cheap dust shroud. The quality for the value on these is great. Each cup took off approximately 50 ft.² of mortar.

These are sad. You get what you pay for I guess. Each segment on the wheel had about 4 diamonds. The wore down quickly and didnt do much grinding. Spend more money and buy quality. Your job will be less frustrating.

Attempted to use to remove thinset from concrete. Hardly any diamonds on the cutting wheel, was barely removing product, job would have taken forever. Not worth the hassle. ended up buying a Norton wheel for $45, cut right through the thinset no problem.

I used one of these grinding wheels to level out some uneven concrete. They ground it down very well, taking off even more material in a shorter time than I would have expected. A good value also.Highly recommended.

Doesnt fit. free return drop off only!. So now I have to spend money in gas to return....
