Repeat order,very good quality!

Nice discs and good performance.

Good service, and they delivered the goods fast, the prodducts are also nice.

The tools match my STI machine well and work well on grinding.

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

I have used the tools to level my concrete and the performance was great,I like this.

The delivery service is good and the package looks nice and sealed, haven’t use them, will evaluate after using.

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!

The products were pretty aggressive and worked fast on the concrete. Also arrived on time. Would buy this again without hesitation.

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!

Did a lot of grinding and the disc still looks to be in great shape. Would recommend to anyone.

This made short work of concrete. We used it to shape and smooth thinset and I can't imagine it being any easier than with this. Shaping was quick and we were able to give a smooth finish. This is clearly capable of much more. After 2 large area thinset were finished, the tools looked like it had hardly any wear.

We just bought a STI premaster machine to do the heavy work,so I ordered a few pieces discs from DTS to have a test. Would comment again after the test is complete.

Used these diamond discs to grind the concrete for surface preparation. Very aggressive to removal the coating on the concrete.

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.

I have used these pads for sanding down a concrete patch but it did the job perfectly and quickly.

Worked very long time, left a lot diamonds after job finished.

It fits my STI premaster machine, powerful with grit 16 which I ordered 24, impressive!
