I bought this to grind out concrete on the slab of my home. The concert is almost 10 years old and very hard, but the diamond tools cut fast and very aggressive! Still have 3/4 of the grinding surface left on the tools. I would certainly recommend it.

The grinding heads worked well with my HTC grinder. Removed a lot of carpet adhesive and smoothed out a small patio work flawlessly. Hardly any wear I think it will hold up fine for the occasional use.

I’ve only just begun to put this to work, but so far I’m satisfied with with these grinding heads. I did not have any fitting issues, went right on my HTC grinder. Almost works to well, very pleased so far.

The products I bought from DTS are very suitable for my HTC grinder. I am very happy to say I picked a great product to knock down the raised up concrete in my backyard. I had to stop half way through the project to sweep up a bit and to let the grinder cool down. I'd recommend this product to anyone who needs to grind concrete.

The grinding heads worked well. I was concerned that using them on aged concrete that the tools would not hold up. But the grinding heads really surprised me. Good quality for the task of grinding concrete. I cut off an area in a short time without degradation to the heads.

The grinding head cut very well. It removed the concrete very quickly and left a smooth finish when done. Perfect size and price.

These grinding tools are well made and effective. Performed beyond expectations.

Much cheaper than local store's HTC EZ change grinding tools in my region. Performed same as original HTC diamonds.

Received on time,very good so far. My friend JIM told me this resourse websiote to buy premious diamond tooling at very cheap prices. I will get back to buy more for my next floorrestoration jobs. Thanks JIM. Thank DTS diamonds.

Great EZ change tools, fit good my HTC machines. Grind very good on hard concrete.

These tools are GREAT!! So easy to use - important to follow directions but they are really easy to work with and top quality. I loved having the different levels of grit and weight in one set and you can't beat the price.

Excellent product… serves to remove grout and make preparation of surface also remove linings and paintings.

These are great. Perfect size and does the job well!

Used to grind a concrete floor. Followed steps.Did an excellent job

This item worked great and very aggressive.Just as advertised.

Good appearance with my Kichen Floor after grinding~

Used it to remove tile backing glue from my kitchen floor

I actually used these with a wet grinder and they lasted significantly longer. Purchased them for a concrete floor that turned out awesome.

Best disc for concrete grinding. Really durable and great price

Excellent. Was able to grind down a concrete patio to smooth finish in no time at all.
