Wonderful products, level my concrete floor well.

Arrived on time and the service is good. Good performance with my machine, the concrete surface is smooth.

The performance is good, left a good finish after grinding,great!

The products grinded my concrete floor fast and smoothly, great value.

I bought this to level and smooth some very rough concrete substrate from a tile tear out on a porch. I ran with water to help cool and stop dust. It seems still has lots of life in it. Made a nice exposed aggregate finish, but pretty smooth.

I have not used it yet, but the products looked really good and arrived quite fast. Can't wait to see how they perform on my concrete floor.

I doubt that the tools will not last long to work at this price, but I nearly have finished grinding the old garage floor, and the tools show no signs of damage to stop grinding. Excellent value for money.

Great! I was satisfied with the grinding effect so far.

I purchased the grinding heads to grind off the thinset after ripping up old tile. And they match my polar magnetic system machine. Worked fast and did a great job on the surface.

All I wanted to talk about this product is its long-lasting durability. This product has longer working life than other competitive tools.

Products grinding down the uneven concrete quickly and smoothly. I'd recommend this product to my friend who needs to grind concrete.

These diamond grinding heads fit well with the polar magnetic system machine.
Fast grinding and smooth grinding.

I have an old Polar Magnetic system grinder, it is my second time to order diamond tool from DTS. The Tools arrived in time and performs as expected. very good value.

I had an old grinding machine with Polar Magnetic system, these Polar Magnetic Grinding Heads had a very great cooperation with my machine LOL, grinding fast and left a lot after a small job. Good tools and recommend it!

Great product. Grinds fast. So far great results with 3 hour of use.
