        Q:The center bushing keeps popping out what is it used for? and do I need it?
        by|Nov 25, 2019
        2 Answers
        Answer This Question

        A:  Some older saws used a diamond shape piece for the blade to fit into, newer saws use just the saw's round arbor. Once the blade is tightened down properly the insert should not pop out. If it does then return the blade for a new one.

        by|Jan 16, 2021
          1 found this answer helpful

          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.

                do not buy!
                If you are cutting tile do not buy this blade! If i could give it negative stars i would. I used it with water, I used it with out water, I flipped my tile, I cut as slow as possible and this is the best outcome i got.

                  ok
                  The saw blade got hot with the short cuts I made in the aluminum trim. This resulted in melting/tearing of the edges, requiring filing every cut. It was faster than making the cuts by hand though.

                  Dear Valued Home Depot Customer, we reached out to the manufacturer and their reply is, "The RIDGID 7” Continuous Rim Diamond blade is not recommended for cutting aluminum; this blade is designed to cut porcelain tile, ceramic tile, marble, and granite.

                  Pictures speak volumes. Here is a picture of the cut with this Ridgid saw blade and a picture of a cut using the Skil blade.

                    Did the Job easily
                    Saved $70 from having a granite company cut a hole in my countertop by doing it myself. Easily fit my angle grinder Used dry at full speed. Cut through 1.5" granite easily Would recommend.

                    Diamond coating wears off after a few uses
                    There's a reason this blade isn't locked up like other tile saw blades. I was cutting tile for a bathroom renovation. After a few uses it started binding against the fence, and it became almost impossible to push the tile through. At first, I thought maybe the fence was not properly aligned. But it turned out the blade was just dull and not cutting effectively. I do not recommend this blade.

                    Hi Andre, We are sorry to hear that you had trouble with this blade. We know this blade is a great blade so we are here to help! What kind of tile were you cutting? Blades do become dull over time very similar to knifes. We recommend you getting a paving brick to sharpen it. You can do this by cutting the brick slowly until you can see the diamonds exposed again. You can also use a sharpening stone or a rubbing stone.
