Review: Works great, cheaper than the local big box stores
Review: For me, this just became the hands down, perfect blade for cutting through cementitious plaster walls. I have a 1939 built house that I am rewiring, and finally got sick of using a sawzall to open up the walls to run wire. A sawzall ended up doing more damage as I cut through one side of each lath, and then started cutting on the opposite side of each lath, and the vibrations ended up ripping out more plaster than I intended. I burned up 3 bimetal blades on my Multi-tool, and didn't even get one opening cut, before deciding to give this Diamond blade a try. For $10 it was worth a try. I have a really high cement and fine aggregate makeup to my plaster walls with no wire reinforcing, and this blade is perfect for my application. Clean, easy cuts through the plaster, then I have to switch out to the wood blades to get through the lath, but it became an infinitely easier job with better results. I cut (6) 12"x12" openings initially (so 24 lf of cement plaster) and I cannot tell any sign of wear. That alone is worth the $10 per blade.
