I had a great experience working with Craig. I needed to change my order and they were already aware of my mistake with the saw size. Everything was so easy and smooth.

CabKing Grinder with attached saw

I have set up the grinding machine which was very easy. I have not used it yet but will be soon. I have taken it apart to set up the saw attachment which was also easy and have used that and am loving it.

They are reachable via chat or phone during normal hours. They are my new go to store for supplies. I have found the quality of products meets or exceeds my expectations.
