Purchased the blade to be used in fire service training. Mounted on DeWalt’s 9inch FlexVokt cutoff saw. This far the blade has been used in a number of training events cutting automobile hoods, trunk lids, laminated windshield glass, rebar, chain, padlock bodies and shackles, and lightweight metal roofing/siding. In more than 150 cuts, the only wear is to the branding/labeling. The diamond media has shown no significant loss and the blade continues to perform as consistently as blades priced double the price of this blade.We run these exclusively on our Rescue Saws. Best universal blade around.I cut some metal hurricane panels and it worked great. So far so good.Picked this blade up in Amazon Warehouse for under 40$.What a Blade, I installed it on a new Hitachi cut off saw and it has cut everything I have thrown at it from 8" I-beams to 6" thick concrete.Love itThese are great...we cut everything with them !Didn't cut rebar as good as my cheap blade
