Diablo Steel Demon Cermet II Saw Blade for Medium Metal - 10" Diameter, 50 TCG Teeth, 1" Arbor, .083" Kerf, 0° Hook Angle, .071" Plate, 3000 Max RPM - D1050CF

Blade remains sharp for a long time. Cut slow, let the blade/saw do the work. Hands down the best and only blade I purchase. Best durability of any blade I have used.

I was totally impressed, this is my first try at a metal cutting blade. I had a drum to cut radially (burn pit) and in all the reviews I read, I saw these blades cut I beams and pipes, but nothing about how they would work on the thinner wall of the drum. It did great, I attached the blade to a dewalt 6 1/2 inch circular saw and it went through it like it was a piece of 1/4 inch plywood, no grabbing of the blade, no binding, just a perfect clean cut. I don't know how much it will cut, but so far so good.

Cut through stainless 2×3×1/8" square stock with ease,no blueing,also cut through about 40 ,18 gauge steel studs and track before dulling slightly,very cleenly,very satisfied!

I have purchased this blade 3 times now - for the purpose of cutting 1/8"x1" stainless steel (304). I have tried cutting stainless with other blades and this one is hands down the best I have used.First - you must have a metal cold saw with RPM less than 2000. If you try to run this on a high speed chop saw, it won't work well and you can't make it work.Second - you must recognise that there are phases of the cut and you need to moderate the down pressure to make the blade last. When cutting stainless steel, the starting cut is through the hard surface of the material and once that surface is penetrated, you need to increase the down pressure to make the cut go faster, about 50% or so increase does the trick.Part of the cooling process is to cut fast enough so that the chips carry the heat away. If you go too slow, you will burn up the blade. If you go too slow, you will see more and more sparks and that is bad because it isn't the material sparking, it is the blade.So - how many cuts did I make? On the first blade, I got about 300 cuts before I wore the blade out. I tried other carbide blades that I had to try to finish the remaing 60 cuts - nothing held up. I bought another 2 blades and started on the next 360 cuts. With the modification in cutting technique, the second blade made all 360 cuts and is now cutting nice and cleanly for mild steel - the blade is still going and the cuts are smooth.

I bought a metal cutting saw (Evolution brand) and it came with a 10" all purpose blade. I wanted a blade strictly for cutting metal and I've heard so much about the Diablo brand, so I bought one and took the factory blade off without even using it. I put the Diablo blade on and began to cut some 2", thin gauge, square tubing. While it began to cut well, sparks were flying everywhere, and I did have a vacuum hose attached and running. I thought maybe the flying spark show was normal. I made six cuts, taking my time, letting the blade do the work while slowly applying pressure downward. By the seventh cut, the blade was so dull it just heated the metal and would not cut. Okay, I took the now dull Diablo off, the one that states on the side, 5X more cutting, and replaced it with the original Evolution blade. What a difference. Very little sparks, and it cut quickly and cleanly. I am very disappointed in the Diablo blade and I do not recommend it. I will stick to the Evolution brand blades.

First, let me admit I don't have a ton of practical experience with using toothed blades for cutting steel. I put this on a 12" DeWalt compound miter saw to cut some 11 gauge rectangular tubing (1.5" x 1" x .120"). I needed to make twelve 90° cuts and sixteen 45° cuts. I made all of my 90° cuts with no problem. On the third sixth 45° cut, it just stopped cutting. It cut through half the wall thickness and wouldn't cut any more. I did not try to force it through. I took my time with each cut. They were nice and shiny and razor sharp. So I don't know if that's about the average amount of use one would get before needing to be resharpened, but it seemed to go pretty quick. I also don't know if tthe DeWalt was meeting the recommended RPMs for this blade. Still way better cuts than cutting wheels and portabands. The teeth held up fine. None broke. I will get it resharpened and keep on using it.

I did buy this for cutting 316 tube, and it does it very well.
