SHDIATOOL 4-1/2 Inch Double Row Diamond Grinding Cup Wheel for Concrete Granite Marble Masonry Brick Fits 7/8 Inch Arbor

Very effective, long lasting tool for grinding and leveling concrete. Fit my standard 4 1/2 inch Bosch angle grinder, which was fine for small areas. For a larger area (100 sq ft) I rented a heavier duty 4 1/2 inch Makita angle grinder from HD and used this disk (HD does not rent grinding discs). Did the job with no noticeable loss of abrasion. Great value.

I bought this for a 7 inch Makita grinder to grind the edges where my sidewalk has heaved due to tree roots. In combination with a dust collector, it has made the job worth tackling. Contractor estimate was over $1500. I have about $400 invested between the grinder, this disc, a super powerful shop vac, and a few misc. safety items. I would highly recommend this for any grinding job you are contemplating.

This wheel grinds through cement, granite, like butter!Using a large angle grinder to get an even surface takes a little getting used to as its easy to make groves quickly. The key is holding the grinder without putting any pressure on it. Just let the wheel work. I smoothed a rough troweled garage floor in one day to prepare for epoxy prime. Hint, avoid breathing in dense dangerous grinding dust by wetting your concrete and sucking up the slurry with a wet vacuum!

My turbo wheel wore out ridiculously fast but I think it had more to do with the rpm I was using with my grinder (10,000+). I think the recommended rpm for this wheel is something like 7,000 (?). I have had amazing results with every SHDIATOOL product I have used in the past so I am reluctant to blame the short lifespan on the wheel. I'll buy another one and not run it at such a high rpm.

I have a water feature in the backyard with tiles that were cemented to concrete edges of the waterway. Tiles had come loose over time, but all the adhesive was still stuck to the waterway. I bought this the grind away all the adhesive/cement and it works great. Just what I needed. Used this on a Milwaukee 7" grinder.

Used it the day of arrival. Worked great. Did 1.5 yards of new concrete. Too many rocks above the surface. Sliced through rocks with ease. Not totally perfect but good job

If you have steady hands, I was able to shave down granite instead of trying to cut an 1/8 of an inch off of the edges. I did nick the edges in a few spots but was able to hide them with wet sanding and smoothing out the edges. Great pickup and use it on my cordless grinder. Was wonderful.

Will definitely purchase again when needed. I built a sidewalk and used this wheel to knock down raised area's (many of them) and this wheel cut through and leveled out everything without strain. Still have meat left on the wheel for another project.

The Double Diamond work great in getting rid of the THINSET on my concrete garage floor. You need to close off the work area - top to bottom, side to side completely. The amount of dust is incredible. I waited for a rainy day to start grinding away with the garage door open. The cement dust is very difficult to spray off and gets into, onto everything! Dust mask and eye protection should be used. Maybe consider the vacuum attachment.Grinding was the easy part. Dealing with the dust was the hard and long part. later

This disc works awesome. As many others say the dust flies though. We just took all the seems and burrs off of a concrete wall that is 10 years old. Its 30 feet long and 4 feet high and all polished now and still have 1/2 the disc left.

Had a area small of 120 sq/ft of thin set to be removed, to much to chip away. Used the SHDIATOOL 4-1/2 Inch Diamond Double Row Grinding Cup Wheel, was able to remove in 4 hours. A novice handy man as myself it worked wonders. A tremendous amount of dust, I had to buy also a dust shroud and attach it to a shop vac when using the wheel. For the price I can't complain. Excellent product!

Amazing for removing tile thinset off of plywood, however make sure you have a good grinder I burnt one out. Even removes staples and nails that are raised to level floor out. Great disc.

Decent for the price, managed to grind 450 square feet of concrete that was covered with old tar residue, by the end the job the wheel was done
