The diamond grinding discs I purchased worked wonders on my concrete driveway. They efficiently removed years of wear and tear, giving it a fresh and smooth look. Highly impressed!

I can't recommend these diamond polishing discs enough! The quality is exceptional, and they provide impeccable results. The supplier was prompt with the delivery and provided excellent customer service. I'm delighted with my purchase!

Premium quality and the sevice which the company offered was very nice.I will buy again from them soon!

Repeat order,very good quality!

Easy to install on my machines and the performance is good.

Did a great job leveling and smoothing parts of the concrete floor in my basement. After a couple of hours of grinding, still has lots of life left. I have no complaints at all. Only piece of advice I would give is that you will want to have a vacuum or water readily available for dust control. Overall a great product!

Just received a few days and haven't put into use. The products seem to be in good condition. Will test the product and comment on it recently. If it is good, will buy again!

We purchased this to grind over the walkway of my patio. This grinds away hard surface and works great. It must be tough because what we are grinding is really hard. Don't know how long it will last but it is meeting our need!

I have a STI premaster machine, DTS diamond discs are of good quality after testing, much cheaper than the diamonds we get from local shop. Recommend.

Amazing STI diamonds, Works great. Better than I expected. Good design beveled edge segments for grinding over gaps on the floor.

Hello, the product was received and seems to be in perfect condition, will mount and use in my work, if good, come back to buy thank you!

Good durable product, great price, fast delivery

We are removing the old vinly tiles and use these disc to grind for new ceramics.

Made a job I've done before soooo much easier

I am very pleased with the item That's the most attractive price I've found. Highly recommend this seller!

I love this disc for levelling concrete, but I should have put on my dust mask first!
