    Answer This Question

    A:  I used this blade to remove a half inch from the left and right side of the opening in my granite counter for a replacement cooktop. This was best masonry blade I have ever used. Cut was smooth clean and fast. Dry cut with minimal mess.

        Q:Can I use it to cut a concrete floor?

        Answer This Question

        A:  Yes you can, but it is designed more for cutting porcelain tile.

        by|Jan 19, 2023

          A:  Dear Doug: We appreciate you reaching out. The RIDGID 4.5 in. Continuous Rim Blade with Mesh Rim can cut concrete floor but will shorten product life since this blade is formulated for tile and natural stone. We recommend the RIDGID segmented diamond blade instead if cutting concrete floor, Model #HD-SG45CP/Store SKU #134530. Please feel free to call us at our RIDGID customer support number at (877) 224-2969 so that we can help answer any other questions you may have.

              For an angle grinder dry blade for tile....
              anyone who has ever tried to cut tile with an angle grinder knows it's almost impossible to do it without it chipping or breaking from getting too hot. this blade is not perfect but it is hands down the best blade for an angle grinder on tile. I've remodelled 4 bathrooms with tile floors and standup showers without a tile saw...(broke down half way through the first bathroom.) This one blade has made every cut since then and very well at that. it was a little more time consuming having to spend more time filing the edges but I'm am definitely impressed by this. awesome job from rigid.

                    Did exactly what's I bought it for
                    This is the only 4.5 inch tile blade I have used but at this point I don't see myself trying anything else. I used the blade to cut two holes in two porcelain tiles for the toilet flange to sit on. You can see in the picture.

                      If you're going to cut ceramic tile, use the larger wet-saw - each test piece of ceramic tile heated up and broke, rather than cut clean. If you're going to try to cut any metal, find anything else - a sawzall, a grinder, someone else's blade. See pics of unsuccessful metal cut (grazing surface) a moderately successful metal cut (softer material) - pieces of ceramic shattered, leading to nothing useful to photograph

                      I am getting very clean cuts with this blade in a small wet tile saw and it also works great on my grinder without being wet.
