    Cuts thin brick like butter
    I purchased this blade to cut thin brick for a fireplace. It did the job perfectly, making nice clean cuts. The blade can be used for wet or dry cuts, but I personally used it dry and it cut like butter. It was easy to install on my DCG413B Dewalt angle grinder. It comes with an adapter ring if installing into a non-Dewalt power tool (I did not need the adapter). Will definitely be purchasing again when I need a replacement.

    I primarily use this 4.5in diamond blade on a battery powered angle grinder. The blade itself is well made and the diamond cutting end, slightly wider than the blade itself. I have only used this to make cuts on ceramic tile and seems to do a decent job. It is quite the challenge to cut a piece of tile without any chipping with this blade which is why I removed a star. The flutes on this blade tend to fill with dust quite easily, but I am not sure if this affects the performance of the blade or not. So far after 100+ cuts, it is still able to make cuts just fine.

    Pros:
    - Long lasting
    - Fluted design that helps if you need to do some small grinding on the edges
    - Works fine on angle grinder
    - Good price

    Cons:
    - Seems to chip ceramic tiles quite easily
    - Flutes clog with dust easily

    Reviewed in Canada on August 13, 2018
    Size: 1 Count (Pack of 1)Pattern Name: BladeVerified Purchase
    Wow!, The best concrete cutting blade I ever used. Cut through hardened lawn edge concrete forms like a sharp saw through softwood lumber. Previously I had only used the standard masonry cutting blades that wear out after cutting one brick, and takes 10 minutes to do that little job. Thought I would try this 4 1/2" DeWalt diamond blade and I'm not sorry I did. I didn't even notice the slightest wear on the blade after completely cutting 2 sections of hardened concrete formed blocks. Cuts at least 15 X faster than the cheap discs with what seems like no wear at all. A really good purchase at a very decent price. Arrived very quickly in the mail.

    I was able to cut 2" thick pavers (cut both sides and snap off) in both straight lines and curves (around a fish pond). The blade worked very well and is still usable. The entire area was about 14 x 14 with a 6x14 walk way. Cuts were needed on some of the edge pieces and on some of the walkway pieces. A full sized concrete saw would not have worked on the curves.
