Review on 💎 Durable DEWALT Diamond Grit Oscillating Tool Blade for Flush Cuts (DWA4242) by Jim Moody

Purchased for use on plaster. I've used synthetic diamond blades in jigsaws and hole saws and never had a problem so didn't think it would be a problem. The blade dulled in the first 6 inches or so as it cut through the plastered exterior. I have no idea if that's due to the quality of the blade or if it's just not made for this application. I don't think so, but like I said, diamond grit has always been a workhorse for me with other tools. The rest of the blade held up well so no major complaints. I ended up using a carbide blade on my vibrating tool and it quickly cut a few holes before needing replacement. Lesson learned I think.
