KSEIBI 644030 Diamond Concrete Grinding Wheel 4 1/2 inch for Polishing and Cleaning Stone Concrete Surface, Cement, Marble, Rock, Granite, and Thinset Removing, Angle Grinder Wheels Cup

Worked great and of good quality, also at a reasonable price. A lot better than the Dewalt I was using before it wore out.

Works great. I used this to grind down thinset on a slab after chipping up ceramic tiles. I wet down the thinset to help reduce dust and this worked perfectly to remove the thinset.

Worked so great! Used to grind down my front porch. Can be used for several uses. Easy to attach, fast! GREAT alternative to the expensive ones at lowe's/home depot.

Worked well! took down the high points in the breakage of concrete.

very good works great i recommend it

There are not enough stars to give this product. Awesome value for the money.I hope this does not come across as a fake review as many of them are.I am so happy with this product. For the price you can not beat it. The Orange, the Blue and the Green stores ( Home Depot, Lowes & Menards ) and everyone in between have similar tools like this priced outrageously high which is a rip off and an insult to consumers.Now that I have vented about the rip off stores.This tool is a monster at grinding uneven cement quickly and leaving you a beautiful finish.I had a front porch that had an uneven slab thing going on and this tool in my Matabo angle grinder made short work of that. More than an inch difference between the 2 slabs and constant over 5 feet... I was able to grind down the difference and feather it out in under an hour! 2 & a half foot wide feather over 5 feet. The bonus is the tool isn't worn out yet. Still plenty of meat left on the cutting surfaces. To say the least I did not take it easy on this tool as I was sure it would fail but what a champ this tool turned out to be.Very balanced, easy to use, no brainer.I meant to take pictures of what I did with this tool but that's my fault for forgetting before applying the epoxy finish.In addition, this tool comes with adapter rings so it can fit various types of angle grinders.

I'm using this wheel for lapidary purposes, so probably different than most other people. I use it on the angle grinder to shape larger rocks and it certainly does the trick. As far as fitting on the angel grinder - note this is not a threaded cup wheel - you'll need the nut that comes with your angle grinder to tighten it on. The quality is fantastic. Works great with my 4.5 inch Bauer that I bought from Harbor Freight. As with many tools like this, let the wheel do the work - you don't need to apply a ton of pressure. I'm really happy with it.

Great tool. I needed to grind some masonry and I tried a straight grinder but took forever. This blade ripped through it fast so use caution as you can easily remove too much.
