DEWALT Diamond Blade for Masonry, Dry Cutting, Continuous Rim, 7/8-Inch Arbor, 4-1/2-Inch (DW4725)

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.

buen material, para corte en muros .. de buena calidad, recomendado !

Outstanding diamond blade for your angle grinder at a very competitive price compared to big box stores. Used it to cut ceramic and porcelain tiles during bathroom remodeling and it cuts through them like a hot knife through butter. Also there is no sign of wear and looks like it will keep going for a long time on the job.

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.

As others have said, this blade cuts thru concrete like a hot knife in butter. Absolutely worth the money if you need to cut/shave concrete for a DIY project.
