Fit well with my Husvarna Redi-lock grinding machines,perform good on my concrete so far. Good purchase experience.

It was cheap and worked grea, worked great with my Husqvarna machines, will order more next month for my future projects.

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.

Received product in 100% match with description from the store.
