Diablo Steel Demon Cermet II Saw Blade for Medium Metal - Triple Chip Cutting Action - 14" x 72-Teeth, 1800 Max RPM - D1472CF

Warning - check the arbor size on your saw. This blade has a 1inch arbor. Most 10in miter saws are 5/8in arbor. No biggy - just order a "saw blade bushing kit" - about $7 - when you order these blades. Worth it. There is a huge difference in materials used to make ferrous metal cuttings blades. Diablo makes their blades with Cermet - a fundamentally harder material than tungsten carbide or HSS tool steel (most other blades). For a detailed explanation see my video. I have worked in material science including synthetic diamond synthesis - this blade uses a unique material, better and harder than tungsten carbide. As a result I highly recommend it for ferrous metals with 2 key caveats. First - it MUST be used in a 3000RPM saw - not a regular miter saw (5000-6000rpm). Over-heating can kill this blade. Too high of RPM and it can quickly ruined. Two - don't push the cuts. Let the blade cut at its natural speed. If you think it is getting hot back off. Do these two things and you can get 100s of cuts from these Cermet blades even in thick steel.

I have an Evolution metal cutting saw that I purchased recently. In the past I have always used a grinder or chop saw with an abrasive blade to cut metal but I was introduced to cold saws about 5 years ago and immediately fell in love with them. They cut quickly, don't make sparks, dust and a mess like abrasive blades do and you can handle the steel immediately without worrying about burning your hand. The biggest drawbacks to these cold cut saws are the blades as they are much more expensive than an abrasive blade and if not used correctly can dull rather quickly. The blade that came with my saw was a multi-material blade which worked fairly well but became dull rather quickly after I cut some stainless steel. I was going to replace it with another Evolution blade that was specifically designed for ferrous metals but in looking around on YouTube found a guy on who had tested many blades and this Diablo came out as one of the best for overall performance. I've used Diablo blades in the past for wood working and was always happy with their performance so I decided to try this one. I've only made about a half dozen cuts so far (on 14 gauge square tubing) but the blade cut quickly, accurately and generated very little heat so so far so good. The biggest question, however, is the one I can't answer yet which is longevity. Will this blade be junk 10 cuts from now or is it going to last for a while? I'll have to reserve commenting on this till I use it more and then update my review but at this time I'm quite pleased.

Put this blade on a old cheap miter saw and it does amazing! Was cutting through 1/4" thick steel without breaking a sweat. Alot better than a cutoff wheel on a grinder. Much faster and cleaner of a cut.

Works better and lasts longer than Milwaukee brand ones and a lot cheaper

Metal-cutting blade for a Skil saw—gets the job done. This blade’s pretty solid. Like most metal blades, it throws sparks when cutting, so keep that in mind. It’s best for straight-line cuts—don’t expect it to handle curves or finesse work. I slapped it into a Skil saw to cut up an old metal roof into 11-foot sections so I could haul it off. It held up well and got the job done. One thing to watch out for: blade thickness. Most Skil saws only take thinner blades, so if it’s too thick, it won’t seat properly. This type of blade is pretty much the only kind that’ll fit a Skil saw for metal work, so when you’re shopping, pay close attention to the width. Too thick and you’re out of luck.

I needed to cut about 18 inches off my metal building roof. I've have a lot of shingle roof experience but this is ,y first metal one so I was kind of worried about burning the paint or jagged cuts. My goto is always a cutting wheel on my grinder but after watching a few videos I decided to try this. Has always Diablo has never let me down. This made a perfect cut. All 10 pieces came out better than expected. Sure there was a few sparks but nothing like I expected. I did set up a clamped down guide to keep me straight. The cut was a lot easier than a piece of osb. If you're doing roofing I did learn a few things, 1- flip the bottom of the panel up and cut the bottom side because there is a lot more flat area for the saw to glide over 2-keep the front end of the saw slightly raised (like 1/4-3/8 inch) so when it hits a ridge or rib it don't hesitate. 3-don't be worried about it, just wear safety glasses

Best blade around. Stays sharp and the teeth dont fall off like cheap blades. I cut a lot of stainless and tubing, no issues after thousands of cuts.

I don’t know how much that’s gonna last but I’m very impressed. I just need to make sure not to put a lot of pressure on it. I think that’s gonna last for a long time.
