This grinding disc worked better than expected. While laying out vinyl plank flooring in my basement, I had an area where the concrete foundation had a slight bulge. I ground the concrete and finished the job took only an hour! Very satisfied with the grinding efficiency of this tool and fairly reasonable cost.

The tools removed the thinset completely and smoothly. Took down the thinset that had been there for over 10 years with complete ease and left me a perfect surface for installation of the new floor. For the price and durability, this tool is an excellent product at a terrific price.

I found nothing to dislike about this grinding disc! I used it to smooth the floor bathroom after I removed the old tiles. The floor is concrete and the grinding disc easily removed all the old adhesive, so that the new tile would go on with no problems. After all the work, inspection of the grinding face of the disc revealed only a slight wear of the edges of the grinding disc otherwise it looked like new. It's ready for the next big job!

Just aggressive enough to level my uneven concrete floor. They really last and do a great job. Good value.

I found these tools are perfect for the job I was facing. Worked quick and made easy work. Fantastic price.

Extremely aggressive grinding disc to remove the concrete floor lippage. Worked perfectly and was exactly what I needed for the job.

Used it to grind down the concrete bullnose around swimming pool to smooth it out. The velcro on the back is very firm and not easy to make the tools fall off. Completed the pool and the tools barely shows sign of use. Very durable and efficient for my whole project.

Worked great grinding down concrete and did it's job with a good lasting durability. I will purchase again in the future.

Fast ship.

Great price! Much Cheaper than what I bought in the past locally, and very effective tool.

Good price for what you pay for, plus it came one day early.

Packed with high quality. A great-looking product.

As advertised, great product.

Good product, and QUALITY. Compliant expectations.
