Good quality

I had been using flat discs but was working hard to create a flat surface on the bottom of concrete products my wife makes. With a 4 or 4 1/2 flat wheel there is just over an inch of wheel surface to use flat, then its up on edge trying to eyeball the surface. With these and a consistent circular motion of the grinding a large flat surface can be obtained.

item as I needed Thank you

Worked well, not sure about the longevity,

Works great for leveling out high spots on concrete patios.

They are extremely less costly and they really smooth the concrete.

Very good price. Fast shipping.

used for sanding my concrete pool, worked perfect good quality.
