i'm no diablo engineer but here's my guess >thinner blade needs to cut less material to get through the same depth of cut >harder teeth allow for more cutting angle which means more material removal so they used both to max out cutting speed and probably had some weird setup for durability testing to get good numbers there too
the shank could've been the same thickness tho. Yes yes, that requires an additiional machining step during production, increasing costs, yadda yadda yadda. But if I'm paying more, I'd expect better quality... riiiiiight??
Probably that they aren't using high quality steel for the meat of the blade since it's carbide tipped, so the shank doesn't hold up. They made a blade better at cutting costs than cutting materials.
My blood pressure went right up the second time it came off and it's not even my tool, I wasn't there and I have nothing invested in the project other than my time watching and you know you can't stop watching.🤬🤬🤬
Picked up a pack of the regular blades, only through a commercial supplier. They're visibly thicker than either of the ones you have. I wonder if they're older stock, or made to a different standard for commercial applications. I used mine on an old Porter Cable Tigersaw, and at full beans, that thing can explode blades at the speed of sound.
Very good video once again! 🎉 Surprisingly I found Makita blades to be the quite good. Not even carbide ones, regular metal Makita blades seem to be cheap and cheerful. I did test so many blades found in Europe I have a video on my channel if you are curious. The test is part of the Parkside 1250W sabre saw video.
I just recently had a job cutting up a bunch of metal poles for disposal. Someone brought craftsman brand blades on site. The craftsman metal blades were literally rounded smooth before even cutting through a single pipe. The dudes with diablo blades were still rocking the same blade at the end of the job. I've never used Makita but will keep an eye out for sales
Push in harder push down less... If you push down hard you apply extra force to the weakest part of the blade. You're removing the same amount of material with 5 lbs of force as you are with 50 lbs of force. Also the 7/8 stroke on the cordless hurts it's performance. Edit: They boned you. No excuse for shaving material on a blade that expensive..
in order for a regular blade to cut through metal, it needs to be tough and hard, so they are generally made from at least two sheets of metal forged together, hence the name "bimetal", but if they are brazing on carbide teeth, then the actual metal doesn't need to be as tough or hard, so under stress it was deforming under the locking ball
Carbide isn't as shock tolerant as the bimetal blades are, so make sure you keep the foot of the saw against what you're cutting, and push the saw forward to keep the foot from getting pushed away on the out stroke. Also, those hacksawzalls just suck. Compact reciprocating saws are niche anyways, you want the longer stroke whenever possible, but the milwaukee ones are the worst I've used. Which is disappointing because their full size sawzall is the best one I've used.
If you have a set of Rockwell hardness testing files it might be interesting to see what the temper is between the old blades and the new ones. I bet the new blades are softer right at the point where they anchor in to the saw. But yes, the thickness of the blade is going to definitely going to have an impact upon how robust that connection point is. Not a really big fan of the quick-twist Sawzall concept. I have a 25 year old Milwaukee corded saw that can go through just about anything.
I wish you could post images in RUclips comments. I was gifted a brand new in box never used original 4amp sawzall. Metal case and everything. It's beautiful. I can't bring myself to use it
Two questions come to mind: 1. Have new blades from other companies also become thinner? 2. Do thinner blades still pop out with other recip saws (ie full size sawzall vs Hackzall)?
Why the hell didn't Milwaukee just make the freakin' pin go another mm or two through the blade, so the tapered end can't catch and walk the pin out? That is a dumb design. It's like Milwaukee enjoys it when their shit pops out... (lookin' at you, batteries)
Coukd be shrinkflation, maybe they are trying to get more performance by making the blade thinner as well. Maybe they should find a way to make the part of the blade that connects thicker. Like by like folding it over after the blade has been pressed. Small amount of extra material and an extra folding step but it would make their customers a lot happier.
That’s really disappointing. I always said that whatever the R&D guy at Diablo was being paid wasn’t enough. Put one of their blades on my cheap chop saw and it cut through steel better than some blades cut through wood. They will learn when their sales go way down.
Diablo blades have gone to crap, simple as that, I used to swear by them, still buy the ones for thin metal, but not for thick metal anymore. Just not worth it.
A: lubricate the surface you're cutting, not the blade B: you don't need any more force than the weight of the tool to get through. C: walk the blade, cutting it straight down will just wear one part of the blade more than the rest
Only thing I'll say is I've never had an issue with those blades popping out of my Dewalt 20v sawzall, though it probably has a different blade holding mechanism and I've been getting the longer ones so they might be made from a thicker metal. Either way I agree they cut great until you chip some teeth when you accidentally pinch the blade at some point.
Nice video, i've got a dewalt, and craftsman, recip saw, and ive found the Dewalt brand, metal blades are great, and the Craftsman wood blades are a good value. Ive only ever had the Diablo 10 inch blade for a miter saw and it worked fine, really couldn't tell a difference, between that and the dewalt though, so i just buy bulk, Dewalt, miter and recip blades.
I have Makita’s version of the hackzall (18v, same form factor but with an extra knuckle guard that reduces vibration), use Diablo carbide blades, never had an issue. None of my blades show the wear at the attachment point and they are few months up to ~2 years old.
Yea I usually stay away from the 3rd party consumables & such. Got an m18 hacksaw too & just searched eBay until I found a decently priced new multipack of Milwaukee blades. Those have treated me very well.
Milwaukee doesn't make the carbide blades, or did not, they kick ass normally. I used one to cut a hardened bicycle lock I lost the key for. Did loose one tooth though.
If clearance allows it I'd take a portaband over a reciprocating saw any day. I've been able to cut through all kinds of random stuff without blowing up blades or having them pop off. I cut through a 5" OD piece of solid cast iron the other day and the blade was perfectly fine!
agreed, 99% of the time.. in this case however, it would be much slower, and no way even the biggest clearance portaband would get around the flange on that beam.
@@vanguardcycle I agree throat depth is also an issue, I have in of the big Milwaukee portabands I think it's a 4" width with a 6" throat. I'm a machinist so I'm not usually doing work in the field but it's saved my butt a handful of times cutting things I couldn't just throw in my 8x24 horizontal bandsaw
I just cut up a cast iron tub from the 1900s with a new one I bought in the last month amped cast iron. It up into 10 peices or so no issue. I have no doubt they may or may not have issues when I first got them some were made in Switzerland then Italy now usa at times? They must be iso making them in different plants. Like you I took my calipers out old vs new were within .2 mills different in thickness 3 years old vs brand new. That may help? Also I use a flexvolt recip saw with a 12ah battery and Iet the saw do the work no reason to add weight I wonder if the stroke on the hackszall is to little? Just some inside for you. When I first got them I did the railroad track slice test and it passed if I get time I'll do the new blades and do the same for science!
Little late to the party, just found your channel. The reason fot the carbide tiped blades to be thinner is likely to do with the set. On a standard steel blade the set is provede by bending the teeth a little to either side of the blade making it so the kerf (cut) is wider then the blade and wont bind so much. On a carbided tipped blade the teeth are wider the the blade resulting in the same effect, in order to have the blade the same thickness as the steel blade it wouls require much wider teeth and therfore a bigger kerf more material to remove more horsepower ect... Anyway enjoyed what ive watced so far.
I'm not sure how you're putting the blades in the hacksall but I've run into that too. Usually you got to shove them in pull them out just a little bit till it seats against the fixed pin and then drop the retaining pin off the collar. Otherwise the pin just pitches the blade and it'll go flying past the retaining hole
@@invetegon4596 Not so sure Sawzall is faster than a metal cutoff wheel in a grinder, but definitely less annoying and way safer. Other big downside to Sawzall is cost of consumables. Cutoff wheels are like $0.50-1 each (or way less in bulk), while fancy carbide blades are 4-5X that (or worse at retail.)
i'll tell you exactly what you did wrong; you bought a milwaukee haha. all jokes aside the lever style locking mechanism on the dewalt sawzall has never popped on me. my 110v milwaukee sawzall does regularly (same twist to release spring loaded pin as the 18v hack). the dewalt lock just seems like a better design. that being said, as much as i vehemently despise them, a cordless angle grinder and a pile of .030" zip discs would make short work of those beams.
I’ve abused both my Sawzall, and hackzall for years. Pinched blades aggressively, cut stainless, cast iron, branches but not once have my blades popped out. That’s crazy. Also my blade lock be hella crusty. Still holds though
Blade retaining pin/nub looks like it's too wide, too easy for the blade to slip. I can see the reasoning, it accommodates the variation in holes in the blades. But it should be more pointed with a narrower angle so it's sticking through the hole more and not just resting on it. Thinner blades should be fine then.
Mistake is Wilfukke doesn't make a saw that will lock to a slow speed. I think its a conspiracy so you'll go through more blades faster. OR they're plying the monkey brain when hear go BRRRRRR... I have an old drill from 30 odd yrs ago. Has a plastic "screw" in the trigger that you adjust for variable locked speed. Why couldn't Wilfukke do that?
I have often thought the exact same thing as your conspiracy theory. They know most people will want to get done fast and “high speed cut fast!” I was process welding stainless pipe for a large beverage company for about a year. 0.060” stainless wall was about the only thing we cut/welded and it was almost all with a sawzall and a hardened steel guide. My “fitters/helpers/boss’ kids” would get maybe 1 1/4 3” pipes cut before the blade was roasted. They’d give it full beans with low pressure. Never would listen to me to slow the speed down and increase pressure. I’d get nearly ten cut before the blade was too shot to cut. Cognitive dissonance is a strange high. Oh, and fuck nepotism lol
Back in the day in СССР we would also experiment cutting iron & steal. But every experiment ended the same, trading the samples in for money. Metric system & 230ac the best
All I know that would make me nuts. You read my mind I need blades. Very good analysis’ .my default holds the blade with a screw so I don’t have that issue.
A sawzall blade has to do one job above all. Stay in the fucking saw
After the second disconnect I would have frisbee'd that thing into the fuckin woods. Talk about infuriating
Shrinkflation hittin hard

Shrinkflation of saw blades? New CEO wanting a big bonus?

I think those carbide blades are staying cool because that one keeps falling out, making you stop.

Gas axe don't have a blade to pop out and doesn't need recharging- as much. Also: fire.
