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.

I only received one grinding disc total. I did not get what I payed for.

These grinding wheels wort great but they do wear down faster than the higher priced one. but they did the job at half the price.

Grinding mortar

Might take a few of these to do what you want to do as they seem to wear faster than I thought they would, but they do work well while they last.. One wore out in about 15 mins of smoothing old concrete edges

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.

I used four of these on an apox. 10 by 20ft. Sunroom to remove carpet glue from concrete floor. These will slightly eat into the concrete, so I plan on renting a concrete polisher to finish it before I start coating it with apoxy sealer. I strongly recommend a vacuum shroud to remove dust.

These worked great on my front porch, dry iced that old paint and chips flew off like confetti. Very little scouring of the mortar. Only halfway done with one disc, and thats on thick paint. Dont know if its the dry ice or the disc, but the disc last awhile. Good buy for the buck.

Good item and good product
