Review on Fast Change Diamond Floor Grinding Discs, Set Of 3, Medium Bond, 18/20 Grit by Brian Messerly

I must say, Fast Change diamond floor grinding discs have made my floor polishing task much easier. The set of three medium bond discs with 18/20 grit are durable and efficient in grinding and polishing concrete, terrazzo, and natural stone floors. They were easy to attach and detach from the machine because of the fast change feature. However, I couldn't help but notice that they tend to wear out sooner than other discs I've used in the past, which is why I gave them only three stars. That being said, these discs are still a great addition to any floor polisher's toolkit, and are sure to make your work more efficient.
