Works as it should. Being a first time user very I'm happy with the out come.

Excellent product, very well made, excellent for rough concrete, etc., recommend!

This was a great purchase! Fit my HTC grinder perfectly.

The disc does remove concrete quickly and I follow grinding with a HTC machine to smooth out the surface.

I ordered nine, 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.

I am using this wet to finish concrete. It is fast and long lasting. It is also a good value compared to other options out there.

This works fantastic. I bought it to touch up some concrete that we poured. It really takes of the material fast.

This was awesome for removing thin set from a terrazzo floor.

Works well on soft bodied tile, travertine and marble. Good for roughing into shape.

For my intended purpose (cleaning bricks) it made a lot of dust, but was the only thing that work as efficiently.

Very fast and efficient heads.

It cuts and grinds concrete very quickly and efficiently.

They wore out a little after my job in MI, still enough for my next job this month.

This grinding shoes worked very well.

We have coating on our floor that we're removing, to renovate our bathroom. This grinding tool is perfect to remove the material!

Great tools, easy change,even better than the original HTC Diamonds.

Ilike the round segment design, not worry about the rotation direction of machine.

Work great with my HTC grinders, cut fast

Nice disc, excellent customer support

Took thinset off quickly and efficiently,I am using it to scrape paint off of a concrete floor and it does the job easily.
