I thought the blade worked great. I did find out after I had purchased the blade and angle grinder that they (Dewalt) recommend a 2-sided shield to attach to their grinder when using a cutting blade. I needed it for making curved cuts in 1/2" porcelain tile and I was waiting on the item to complete the job so I put on goggles, mask and ear protection and went for it. You will definitely need to wear a mask and goggles and blow out your grinder periodically with compressed air as it creates a lot of fine dust. The blade cut through the tile beautifully - I made a few passes so the blade would not have to work so hard. I had tried cutting the tile with other diamond-tipped jigsaw and rotary tool blades and nothing compares to the efficiency of this blade and the grinder.
