SALI Diamond Concrete Grinding Wheel 4 1/2 inch for Polishing and Cleaning Stone Concrete Surface, Cement, Marble, Rock, Granite, and Thinset Removing, Angle Grinder Turbo Wheels Cup 115*22.2*10 MM

A good value. The blade is nice and thick.It fits well on my 4 1/2 inch grinder.I found it works well at cutting. The durabilityof the blade is good. There is going to besome dust. I wear a mask before using.Yes, I would recommend this product.

Works great with the swirl designed teeth.

Had this nasty really difficult mortar mix we couldn't get up. Worked great on our Harbor Freight grinder. TAPE OFF YOUR PROJECT or get a dust shroud cause it made one heck of a mess inside the house. Still having fine dust settling and it's been over a month.

I've just tested this briefly on a concrete block, but it seems to cut nicely. I'm planning to grind down a concrete threshold to clear a storm door that's too tight.UPDATE: I used the diamond grinding wheel to reduce the height of a concrete threshold, about 36" x 6". The material removal was slower than I expected based on online videos. I removed less than 1/8" on average, and pretty well used up the abrasive material. I did some of the grinding iwth the surface wet, and it seemed that progress was slower wet than dry.

I really liked this grinding wheel; I have been removing tiles and thinset from my bathroom at first I was using a demolition hammer with a thin set scraper to remove the thinset. The Thinset was very stubborn and the demolition scraper kept taking out chunks of the concrete. Once I tried this grinding wheel it removed the thinset very quickly and smoothly. I removed all the thinset in my bathroom in a 1/4 of the time that It would have taken with the demolition scraper and the over all job went much more smoothly I don't have any large chunks taken out of the concrete from the grinder. After removing the thinset and finishing the job the grinding wheel was still in very good condition with tons of life left in it. Very good quality for the price!! Would buy this again.

Great price for a disc that works.

Less expensive than others but worked great for me. I had to grind down an edge of a sidewalk segment that was about 3/4" above the next one at the expansion joint. 20 or 30 minutes of grinding tapered it off nicely. Disk showed minimal wear after. Fit my Pittsburg (H. Freight) grinder arbor perfectly (use the nut that came with your grinder.) 2 other adapter rings were included for I assume other grinders with larger arbors. Like all grinding disks, wear eye, face and hearing protection plus appropriate dust mask.

I bought 3 of these for a job to take Synthetic Plaster off of a plaster finish on a House . This Grinding wheel really works , The only problem is making sure to hold it plat for a smooth finish . Have done more than half of the 3 bedroom house and the first disc is only about haft worn down. I tried . Pressure Washer , Heat Gun , scrapers and nothing works like this. Creates lots of dust but Good tool.
