Cheap but good in my review

I have water that stands in my garage and I needed to carve a slight trough to allow water to drain on one side. I was skeptical that this would last the 3 feet I needed to so starting at a slight angle and ending 3/4" deep and look good. It did the job and barely wore on the metal. This will do the job and then some.

Pros
  • Abrasive Wheels & Discs
Cons
  • May not be effective on curved surfaces

worthy for the price

worthy for the price for small project at home, such as to grind down the uneven sidewalk concrete due to tree root grow. That's my feedback!

Pros
  • With a high-quality design and construction, you can rely on this tool for years to come
Cons
  • May not be suitable for wood work

Grinds well but wears out quickly

Ate through concrete effectively but after an hour of grinding the metal itself was ground down almost completely and started sparking. A single use disc.

Pros
  • 5000sqft grind, 6 wheels attached to a sanding machine, worked well
Cons
  • May wear out faster when used on harder materials

Worked Wonders - my new review

This did just what we needed.We needed to grind off the flashing from our concrete countertop to fit the stove that was 1/8” to big. This did the job quickly and evenly and worked well with our grinder.

Pros
  • APPLICATION: Our 4 in diamond grinder wheel used for dry/wet grinding of concrete, granite, stone, marble, tile, masonry, and some other construction material to smooth uneven surfaces and remove flashing
Cons
  • May require professional training to use effectively

This wheel is an absolute beast!

This grinder wheel laughs at concrete. Keep this wheel moving as it will dig in if you linger too long. It generates a ton of dust (no surprise there). Advice: let the speed of the tool do the work, do not push down with much if any force. I needed to use two hands to control the tool or else the tool would boss me around (again, no surprise here). Considering that you are grinding concrete the wheel has a surprisingly long life. The only con is that I could not use the regular tool for…

Pros
  • It can be used for dry or wet grinding, allowing for flexibility in your work
Cons
  • May require frequent replacement

Best value on my review.

You cant beat this cup wheel for the price. I bought 2 to grind down 180 lin ft of stonework (so the stone caps would fit tight). I doubt we used half of one wheel. Will definitely buy more as needed

Pros
  • {}
Cons
  • May not be safe for use around children or pets

grinding concrete good for me

It worked as well as I expected for the price. Some similar tools cost crazy money, you have to have a special grinder to mount the grinding disk to, and that's very expensive. For a DIYer like myself, it worked just fine.

Pros
  • The Sunjoyco Diamond Cup Grinding Wheel is made from high-quality materials
Cons
  • May not be effective on irregular shapes

Grinds great, but wears out pretty quick.

Had to grind down a 10 x 10 concrete pad. High spots and bumps. These worked great but took 3 of them to do the job. Wears out pretty quick but I would buy again if needed.

Pros
  • Buena herramienta para quitar detalles y pintura.
Cons
  • May be more difficult to store than other grinding wheels

This thing is awesome!

Using to remove old epoxy paint from concrete patio floor prior to installing ceramic tile. It works very well to do that. Fast paint removal, with not too much effort. So far I have removed about 300 square feet, and I cannot believe it is still sharp, and removing the paint down to the concrete the same as it did when I first started, leaving a clean smooth concrete surface. I'm also noticing that there doesn't seem to be much difference in the thickness of the blades since I started, it's…
