DIABLO STEEL DEMON CIRCULAR SAW BLADE REVIEW! -7 1/4 BLADE- CERMET STEEL CUTTING 48 TEETH

[@robsdeviceunknown]

I NEED THIS! I didn't know they has them for circular saws yet. I assumed the speed was too high. $30 bucks is NOT bad. All my cutting discs, flap discs, saw blades etc are ALL Diablo. Everything in my shop. I am definitely a fanboy.

[@MarkThomasBuilder]

I showed it cutting 1/4" steel on my Instagram story and it worked well on that. If you buy one, let me know how it works out for you. Thanks!

[@carloscervantes364]

Diablos the only way to go and if it ain’t dewalt it can only be your fault 💪🏼

[@AODNEO]

Found this review to be VERY helpful. Thank you very much

[@MarkThomasBuilder]

You bet, thanks!

[@wkw4095]

Made my work way too easy....cut steel like thin plywood and super clean too! ... Very little spark effect....I like it so much that after using it I'm randomly watching youtube videos of it. I'm amazed with this thing. It's a game changer.

[@MarkThomasBuilder]

I know what you mean. I couldn't believe it the first time using it.

[@williamrichardson5719]

Thin metal. Use it on 1/4 inch.

[@soundslight7754]

Excellent performance, I'm definitely sold. Thanks for the info man.

[@MarkThomasBuilder]

You bet, glad to help.

[@jasonlevesque9303]

My buddy just gave me one of these blades. Going to try it out soon and see how good it works and lasts.

[@MarkThomasBuilder]

It's an awesome blade that makes nice clean cuts in steel.

[@rohanmooneyan6613]

Really amazing to watch very good video and explaining well for a new debut like me make a good guide.

[@MarkThomasBuilder]

Glad you enjoyed!

[@nguyent2477]

Makita circular saw and Diablo number 👍

[@MarkThomasBuilder]

Good choice!

[@moswtd]

I couldn't even cut 1/8 inch mild steel and I had only used it a few times on roofing sheets. Not worth the $75 NZ dollars. I had to switch back to traditional angle grinder with cut off disk.

[@todds5956]

Can this cut 1/4” thick angle?

[@jasonholloway2476]

Just cut 1/2" plate in my shop yesterday with the 7-1/4" blade, so yes, it will cut 1/4" angle.

[@keithdavis3819]

Well presented but how can you review products you're paid to promote? I'm not that bothered just reckon if it's a promo video it should be tagged promotional video rather than review?

[@Kenji16684]

Hi do you think it will work fine and safe if i put those blades on my miter saw? workzone brand with two speeds, 3800rpm and 500rpm

[@MarkThomasBuilder]

It sounds like it will work, but I would see what Diablo says as far as what it's rated for. I though it was only circular saws, but maybe there's more info on their website.

[@Rw-bt1iz]

Debating this blade and a separate cordless circular saw OR a portable bandsaw. Fence builder, i pound chain link posts into the ground and cut the tops to height. .065 wall thickness, residential posts. But i will make up to 50 cuts on a job and do 1-2 jobs a week

[@MarkThomasBuilder]

I haven't had a chance to test a portable bandsaw yet. I reached out to my friend Clint at Tool Review Zone. He recommended the portable bandsaw. I'm have some new tools coming in soon, hopefully one is a portable bandsaw , just so I'm familiar with them.

[@davidbradford6624]

Plan on cutting hurricane shutters 20 or so.. 48 teeth recommend or higher?

[@tinnedanger]

You only cut sheet metal.. Have a go at 1/2" show how that blade claims how it should work.

[@IMPACT-NATION]

Very impressive blade. I bought one to make my life easier at work cutting steel. Have you tried any other brands you could recommend that are worth trying out? I’m on a quest to find the best one I can. Looks like it’s going to be pretty hard to top this one

[@MarkThomasBuilder]

I've had good luck with the Milwaukee M18 Metal Cutting Circular Saw. The blade seems to cut similar to this Steel Demon. Thanks for tagging me in the sawzall post. What's the next step?

[@IMPACT-NATION]

@@MarkThomasBuilder yeah that metal cutting m18 is awesome from all the videos I’ve seen. Did you get to see the video of me cutting the steel? And how I set it up? I can send you a link on Instagram if that’s easier. Truly Mark, if you have other things going on and don’t have the time right now I understand buddy. It would just mean a lot to me if you were able to

[@MyNameWasTecho]

Looks like a great blade. Was this in a standard circular saw or a metal cutting one?

[@MarkThomasBuilder]

This is in a standard saw. My DeWalt saw is probably 10-15 years old.

[@todds5956]

Can I put this in my chop saw? The proper diameter of course

[@jayvanwyck4717]

Thank you! Have a recommendation, to use Hougen Slick-Stik, part no. 11745. Really increased longevity for me, and a bit quieter. One stick last about 4 blades. Use it for drilling metal with rota cutters and drills bit. A real improvement over other lubricants I have tried. Plus classified as Non-Hazardous.

[@MarkThomasBuilder]

Thanks for sharing! I haven't tried it yet but think I will

[@nickwit21]

Sold! Need to cut down the length on a metal screen door. This should work fabulously. Thanks. KZbin for the win!

[@MarkThomasBuilder]

Awesome, good luck on your project!

[@dptp9lf]

Thanks for the great video! Do you know how well it works on non-ferrous metals? I have a non-ferrous diablo that is awesome but it's 12" and i would like a smaller blade that works for both ferrous and non-ferrous metals. Cheers,

[@MarkThomasBuilder]

I haven't tried this on non-ferrous metals. I've used the Diablo wood and metal blade on wood and copper it it gave it a nice clean cut.

[@pbc1951]

What RPM Saw did you use? Will this work on my 5000 RPM Saws? Do I need a 3500 - 3700 RPM Saw ?

[@MarkThomasBuilder]

I believe it was the 5,200.

[@MrLinkiscute]

I get about 4 feet cutting 1/4 inch steel before it dulls with this blade

[@MarkThomasBuilder]

Humm, I haven't measured it to see. I'll have to try it sometime.

[@jonathancall9967]

Not a fair comparison, you should use a abrasive 7 1/4 circular saw blade in your circular saw to compare against the demon Diablo blade.

[@craigmonteforte1478]

Great Score Mark , I am not a MetalWorker by Trade but its a nice blade to have for an occasional need to fabricate with metal

[@MarkThomasBuilder]

+Craig Monteforte This blade makes it easy to get into metal work. You’ll like the fast clean cuts.

[@oficinadebicicletasfabaobi535]

Hello, is yours circular saw for wood cutting? Thanks

[@MarkThomasBuilder]

I bought this circular saw for wood cutting a few years before making this video. Once I switched out the blade to a Steel Demon, I only use this saw for metal and steel. I have a cordless saw for wood now.

[@Mixwell1983]

I dont really cut metal so I got a Diablo 7 1/4 cutoff disc but I am really wanting to get the steep demon blade... Looks awesome

[@MarkThomasBuilder]

This blade is very handy for cutting steel.

[@Mixwell1983]

@@MarkThomasBuilder yah since I dont cut metal often why deal with slower cuts and sparks.. For $30 and minimal cuts this blade will likely last years

[@feelathome77]

Title says 48 TPI (tooth per inch), it should be teeth as indicated on the saw it self, minor typo.

[@MarkThomasBuilder]

Yes, thanks I see that now. I'll change it.

Can it still be use for wood?

Not really. They make a wood and steel blade that works better for that situation.

Great blade..... Great Video!! Question... Would this blade cut 1/16" (.063) aluminum diamond tread plate (stone guard) clean with no burrs? I'm cutting for chair rail. I know they make a blade for aluminum but, I'm looking for a great dual purpose blade for both steel & aluminum. Thanks

[@MarkThomasBuilder]

I think you need one blade for aluminum and the Steel Demon for steel. I don't believe there's an all purpose blade, from what I've seen.

[@jvalenzuela1298]

I have to cut some metal coupons for a weld test, can 1 inch thick and down or what’s the limit if thickness I can cut metal. 7 -1/4 is the saw Im looking to get. Thanks in advance

Their thick metal cutting blade, with 38 teeth, is rated for steel 1/8 to 3/8-inch thickness.

DW364 DeWalt Circular Saw. I think it's 10 years old.

@@MarkThomasBuilder Great, thanks for the info!

[@das250250]

These new metal blades take the standard higher speed saws ? You are cutting at what speed ?

[@MarkThomasBuilder]

The Dewalt saw I'm using this in is the DW364 which is 5,800 rpms. I'm not sure if the blade is rated that fast, but it's worked out for me so far.

[@dingpuiamsv219]

Can i use this blade with a circular saw whose no load rpm is 5000

[@MarkThomasBuilder]

I believe the rating is 5,800 max rpms.

[@yofex3548]

Can this blade be used to cut rebar, say 10 mm thick? Thanks

[@MarkThomasBuilder]

I believe so. It cuts threaded rods up to an inch. I didn't see anything mentioned specific about rebar though.

[@jasonlevesque9303]

I believe it can no problem, even 15 years ago I used Diablo circular saw blades for doing hardwood flooring repairs and those blades way back then cut thru nails and all types of metal in flooring and kept on going no problem. And I always used the cheap Skill 13 amps circular saw. And those blades made a big difference in how that cheaper saw made cuts in all kinds of hard woods. I cut a ton of oak, mahogany, walnut, hardwoods and those blades lasted for months. 👌 and the new ones are way better now.

[@hdrjunkie]

do these blades come in 6" size? My only circ saw is a Porter Cable Saw boss 6" I LOVE it and saw no reason to go buy a 7" or bigger saw.

[@MarkThomasBuilder]

Not yet that I recall seeing.

[@jacobalmanza6375]

Do you think I could cut .125” titanium rods with this blade?

[@MarkThomasBuilder]

I don't think it's made for titanium.

[@yusuff531]

Hi, can we use this blade to the normal wood circular saw 7 1/4 like bosch gks 7000? It is safe to use on normal wood cirular saw?

[@MarkThomasBuilder]

I recommend the Diablo Wood & Steel blade. It's a combo blade that works on both. This blade in the video is just for steel. I made another video on the wood & steel showing how it works.

[@doggyide]

@@MarkThomasBuilder so, the answer is yes, if I want to buy it only to use with steel rectangular tube is correct?

[@bigislandtinyfootprinteduc8809]

What about coordinated metal roofing ? Burrs?

[@MarkThomasBuilder]

I haven't really had too much of burrs from this blade. I think it would cut corrugated roofing, but haven't tried it on that yet.

[@arielnitro84]

can i use this 7-1/4" (184mm) blade on makita 5800nb circular saw (180mm)?

[@MarkThomasBuilder]

It's rated for up to 5,800rpm, so I'm guessing it would work. Check the Makita rating to be sure.

[@arielnitro84]

@@MarkThomasBuilder yes, thanks a lot. the rpm is just fine. i am worried that the size variance of 4mm will result to malfunctions. will buy this cermet blade very soon. more power.

[@kennybo3009]

Can this cut a gym power rack 3x3 11 inch gauge?

[@MarkThomasBuilder]

A circular saw will cut 11ga tube steel, but not all the way through in a single pass. The circular saw cut depth is only 2.5". You can make it work by neatly cutting it in 2 passes.

[@mark1952able]

Would it work to cut 3/8" metal lathe /expanded sheet metal?

[@MarkThomasBuilder]

Yes, I would think so.

[@hgherb]

Not many people know that the diablo blades are rated for 1800max rpm and the circular saw are running much much faster than that. The Diablo blades won’t last long. They will work ,but not very long.. just keep that in mind..

[@billeslinger1656]

apparently you didn't read the blade. Max rpm is 5800

[@hgherb]

Bill Eslinger not all are created equal. But for some. they have no idea what to look for and they just grab what’s on he shelves.

[@calical26]

all those blade are just about the same has the one the older metal blade dont last that long i install steal panles make about 10 cut before need to change the blade

[@MarkThomasBuilder]

I haven't cut enough steel with mine to see how long it lasts. So far, so good.

[@CrossroadToCountry]

I have 144 inches of flat bar 1/4" steel to cut. Will the blade last through that much cutting do you think?

[@MarkThomasBuilder]

Yes, I can't say exactly how many inches the blade will last, but I would think this blade would be a great fit for what you're doing.

[@CrossroadToCountry]

@@MarkThomasBuilder Awesome! Thank you. We'll find out tonight! This will save me getting a cutting torch or plasma cutter and spending a ton of cash for just a little work.

Yes, I cut some that size tubing in my video featuring the Magswitch Pivot Angle 150.

It's specialy diablo for steel or all freud blade can do that with steel material?

This is s special blade for just steel. They also make a wood and steel blade if you need an all-purpose blade.

Question of the day: Are you ready to upgrade to the Steel Demon Circular Saw Blade? What item would you cut with this? Should I have tested it on something else?

[@JJ-xw8ir]

Steel Entry Doors Can't find a video of them being cut.

[@hjartland]

Mostly 1" square box tubing. Up to 1/4" wall thickness.

[@AndrewBrowner]

id like to see how long it lasted, cutting something more substantial either 2" square tube 1/8wall or preferably some 1foot strips in 1/4" plate, a regular carbide circ saw blade will cut 16 guage all day and any blade will make one cut in 2" flat bar but will this one make 50 cuts in a row without dulling? ive seen them locally but at 85$ plus tax here in canada i dont wanna find out the hard way i just made a 100$ while fabricating

[@arielmetamorphosis]

Will it cut 1/4 "

[@MarkThomasBuilder]

Yes, they advertise that it cuts 1/16 in. to 1/4 in. wall thickness in plate and bar stock.

I've been searching for a decent independent review of this blade. This is definitely the most helpful one to date. Could you see if there is one for a miter saw? I'd like to use my miter saw for metal cutting. But am unsure if the RPMs, arbors, and the like. Will be suitable for a saw that was meant to cut wood.

[@MarkThomasBuilder]

Thank you! I don't think they've made a bigger metal blade yet. Since the metal it cuts is only up to 1/4", they probably don't have the demand for it.

[@gerardorivera7356]

Question. Will it work in a 7 1/4” miter saw

[@MarkThomasBuilder]

That's a good question. I'm not sure about using it in a miter saw. My guess is that its' only rated for use in a circular saw.

@@MarkThomasBuilder Mark, yes, I use this blade all the time in the shop in my cordless DeWalt 7-1/4" miter saw. I use angle iron, 1x1, and 2x2 square tubing all the time for projects, and this is what I use to cut. I think the main safety issue you want to look at with any carbide blade is RPM. You don't want to use it in a tool that spins faster than the blade is designed for. I believe it's printed on the Diable Steel Demon blade, something like 5,500 RPM.
