These metal bond grinding discs grind aggressively but stay very controlled. I used them on hard concrete, and the surface came out flat without deep gouges, which saved time on the next stages.

These STI metal grinding discs handled my concrete prep beautifully. They're aggressive enough to remove coatings but leave a surface that's easy to polish afterward. Really pleased with the performance.

These metal bond grinding discs perform amazingly well. They remove material fast and leave a consistent finish. I used them on a large concrete garage floor and they held up the entire job without losing sharpness.

Strong, reliable, and easy to attach. These are our go-to tools for warehouse floor restoration. They save use a lot of time and labor.

Every time I use these tools, I get consistently high-quality results. They never disappoint and always deliver the performance I need.

I've been used these metal diamond grinding discs extensively for concrete polishing. Worth every penny.

Received my metal bond diamond grinding discs promptly and they work wonders. Highly recommend this seller.

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.

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!
