The Diablo D0748CF STEEL DEMON is a top-tier metal cutting blade that delivers on all fronts. It cuts through steel and stainless steel effortlessly, producing smooth, burr-free edges with minimal heat and sparking. The CERMET II carbide teeth offer serious durability—I’ve made dozens of cuts, and it’s still sharp and consistent.What really stands out is the functionality.

Highly recommended!

I mounted this on an old chop saw (miter saw), and it works wonders for cutting through metal. I've used it to cut through mild and stainless steel, up to 1/4 inch thick, and 6061 aluminum. I was surprised at how easily. Cutting through that 1/4 inch steel felt about the same as cutting through a pine 2x4. Quick and easy, with very little downward pressure on the handle during the cut. And the cuts are clean and smooth.My chop saw spins at 5000 RPM, and this diablo blade is rated at 5800, so it has been a good combination with no problems. Exceeding the max of 5800 may very well cause problems such as dulling the blade, so keep that in mind if your saw spins faster, and many do.While researching this blade, one reviewer commented that it is good for cutting through metal when the entire blade width is in contact with material. However, it is not good for shaving material off the end of a piece, as is commonly done to make a piece of wood just a little shorter. I can confirm that it's not good for this when cutting steel, as it creates a lot of vibration, and I was concerned that even a tightly retained piece could be sent flying. But for cuts down the middle of a metal piece, it's great.Since I'm too lazy to switch it out for a wood blade to make the occasional wood cut. I can confirm that it's a perfectly adequate wood saw. Not the best for making furniture grade cuts, but just take your time going through wood, and you get a clean enough edge for your rough cuts.

Worth the purchase

Great blades. They last longer than most especially if you let blade do all the work and don’t force it

This blade was well worth it. I bought this for my mom’s bf who was helping me cut hurricane shutters to fit my windows. This blade didn’t spit crazy sparks or sound crazy . We got it in October and we have used it a bunch on other projects and the blade is still sharp and cuts smooth.

Based on experience, I have 4 recommendations for cutting seriously thick steel: The first is to order more blades than you think you'll need. The second is to use cutting fluid. The third is to cut only for a few seconds before pulling out and letting the blade cool down. The fourth is to cut about a 1/8" deep channel, and then use that as a "cutting guide" to finish with a cutoff blade in your angle grinder.I'm using this to cut through 24"-diameter steel oilfield pipe, 3/8" wall thickness. That's a lot of steel.I had ordered two blades, and foolishly let the first one overheat, which ruined it in the blink of an eye. I then mixed up a homemade solution of cutting fluid consisting of a cup of water, about 1/8 cup of waste motor oil, and a generous squirt of powerful dish detergent (enough to allow the oil to emulsify).I then started cutting, making passes, each about 1/16 deeper than the one before it. Before each pass, I'd drop just enough of this DIY cutting fluid to leave a thin layer. After cutting about 8-10", I'd stop and check the temperature of the blade, esp. the carbide teeth.Using this method, I was able to finish my cuts without wrecking the blade. It does show some wear, but still cuts. The only problem with using only the blade to finish cuts on thick material is that I'm pretty sure the blade starts work-hardening the steel at some point. That's when you should finish cuts with your angle grinder.

One of the best metal cutting blades I’ve ever used. Being able to use it in any standard circular saw makes these blades superior to anything else on the market.

How cow this thing is a beast. Cuts through quarter inch steel and it's cool to the touch, that's no exaggeration. Very impressive.I didn't hold the plate down well enough because it was a little bit cupped from welding. Got a big kickback(my fault) and it didn't even break a tooth off. I'm extremely impressed. I also cut through welds with it, it doesn't even leave a burr. It's almost a mirror finish. Totally nuts.
