Wow!!! What quick work the Husqvarna redi-lock grinding heads do on concrete. It took me a few minutes to get the feel of it and to apply the right amount of pressure to apply. I was able to grind out my 3 car garage floor fast with this as well as leveling out my control joints. I like these great tools and buy more for future jobs.

I'm very impressed with these items.There are many different ones for sale, I went this one because of the sale looks very professional.
