Good deal! Don't know the lifetime of this Disc, but they work very well so far

We are a family owned Contracting Company and use these 4-nch discs quite often.Already bought more after trying one. Premium quality and awesome prices.

Bought 4 segments for grits 30, 50, 70, the output is great

Worked great on a store floor repair.

I have to say it is a amazing tools on my floor grinding.

Excellent quality with long lasting

good worked as described
