Arrived today but haven't used yet. F it's as good as the other diamond cutting discs I've used in the past it should be great as a grinding disc.

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

I ordered two disks - both arrived, packed well and in perfect condition. Delivery was relatively quick - I haven't tried grinding concrete yet, so can't comment on how effective they are.

Excellent product. This product did exactly what it was supposed to do

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

Satisfied quality and lasting product. It should use the disk with water otherwise it heats and do pumice plus.

Made a job I've done before soooo much easier

worked great in removing old tile thin set ...

This worked great to remove mastic from my concrete slab. I used the a dust mask on my grinder to help collect the dust.

Awesome for the price.

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!

I am using this to level rough concrete in my garage.It cuts fast and I can get a relatively smooth surface.

Last a long time and really grinds down concrete. I used it to grind a finish off of a concrete floor and it worked quite well.

Fast shipping,good quality.

I have tried these discs last week, My STI premaster grinder work great with the two-pin grinding discs. Premium quality it is.

Very strong, grinds quickly.

Arrived fast,same as descriped.

Good quality. meets my expectation.
