Amped Demo Demon Universal Fit Carbide Oscillating Blade - 3-Pack | For General Purpose Cuts - 1-1/4" Cutting Width, 1-1/2" Depth - DOU125CGP3

(Small gripe, I'm a Christian and I don't like the choice in name marketing calling them diablo. I will continue to refer to them as Freud Industrial.) Now that I'm off my soapbox, these are the only blades I will bother to purchase or use. I have had nothing but frustration with oscillating blades from any other manufacturer. They are all inferior. And I think they know it because these blades are VERY expensive. And yet still worth every penny. Now I will say there standard bi-metal black blades are fine but I don't think you should purchase them. ONLY buy the red carbide blades! They cost a few dollars more and are night and day better. This review is for the General Purpose blades but they also have a great METAL and NAIL EMBEDDED WOOD carbide version that are all amazing and highly recommend. I will also recommend the Bi-Metal BLACK Clean Wood blade (I know what I just said but it's only for CLEAN wood).

This thing cut through a half inch steel bolt like it was nothing! Hands down the best on the market today.

These worked great in my Craftsman 20 V multitool. Used them to cut rotted wood off my front and rear door frames. I've also used their hole saw and other cutting tools and am always impressed with the quality and durability.

I've yet to be disappointed with any Diablo product. Oscillating blades aren't cheap, especially when you consider how quickly they go dull, lose teeth, burn out. I decided to try carbide blades and these are worth every penny. Still on my first blade, after some heavy use, it still cuts like brand new.

These seem pretty good compared to most. Most don’t last wroth a crap. These seem better than average. I’ve tried 3 other brands over the years. Always searching for better ones

Excellent bit

Ive been using one of these blades for months, cutting through hundreds of screws and nails, as well as wood. There appears to be zero wear on the teeth. Just to verify the wear I swapped to a fresh blade and it cuts exactly the same as the used one. Very impressed on the durability. The only drawback is that it cuts slowly in wood, but a I would recommend a dedicated wood blade for that anyway

I’ve been a professional carpenter for over 10 years and have tried a number of different brands when it comes to oscillating tool blades. These seem to outlast the others by a large margin. Obviously how long they last is going to depend on how much you use them and your level of finesse when operating the tool. These are all I buy, they just work. The mixed reviews are probably from filthy casuals who are DIY’ing some monstrosity of a project in their garage on the weekends.

Found this Diablo blade good quality.
