Q:This blade came with a small metal o-ring. Am I supposed to use this? It seems like it may be used for some sort of conversion. Most people who use the ring complain about it slipping. If you have to use it, what side of the blade is it supposed to be on?

Answer This Question

A:  Dear Colter, Depending on the arbor your tool has this may or may not be needed. It is used for converting the arbor size. It should be in the center hole of the blade . Please give us a call at (877) 224-2969 so that we can further assist you; thank you.

      Q:The center bushing keeps popping out what is it used for? and do I need it?

      Answer This Question

      A:  Its an insert for smaller diameter shafts, If you grinder has a small head you need it to properly center the blade, otherwise toss it.

      by|Nov 26, 2019

      A:  The center bushing acts as an adapter. Not all tools have the same size arbor/spindle. If the tool has a 5/8" arbor/spindle then you will want to leave the bushing in so that the blade fits tightly to the arbor. If the tool has a 7/8" arbor then you will need to remove the bushing for the blade to fit on the tool.

        Answer This Question

        A:  No, they would be dangerous, wood can jam the saw. I have seen a double blade saw that cuts all kinds of stuff though. It is called a double cut saw.

          4" angle grinder glass tile cutter.
          It was advertised as a glass cutting blade for ceramic tile. Did a terrible job, I will never buy another one. Literally destroyed the ceramic tile as I was cutting it.

          Used this Ridgid 4" diamond blade to cut out 8 electrical outlets in ceramic tile backsplash. Worked perfectly on a variable speed grinder. This was the correct tool for the job. Picture is of the blade condition after use. I expect it has a lot of life left in it. Thanks Ridgid!
