Came here because im about to cut off thr exhaust on my car and throw something better on there. I've had these Bosch blades forever but never used them or the saw. Everyone said to use a Diablo blade but I'm broke and don't want to spend any money on blades ... happy to see the Bosch ain't junk but also that pretty much any blade will work too.
1. It's not about speed but longevity 2. Using cutting oil will make each blade last 10x longer If ur not using cutting oil... U might aswell just burn paper money notes.
wax or bar soap is sufficient. you just want to reduce the excess friction oils are typically for dilling, tapping and die threading. although it works just as well for sawing, its just messy.
Definitely other factors to consider. However, I feel like if a blade doesn't cut quickly when it is new then it certainly doesn't get any better with more cuts.
@@contractorscompassTortoise and the hair man. lol Some steel is more durable than others when heat/friction is involved. maybe it cuts fast, but a run to the store because you have to buy more blades could make quite a difference on a job lol. great vid regardles
Okay, so I'd like to assume I have much expertise here but I'm sure there are others that would put me in my place. I'll start off by stating I'm a dedicated Milwaukee guy, but that goes only as far as the tool. When it comes to blades I want the best, I don't care if it is Lenox, Milwaukee, Dewalt, Bosch, etc. At the end of the day I want the job done the fastest and the best. Recently I've had to cut through 8 feet of 1" ABS (American Bureau of Shipping) grade steel plate. I cut through about 1/2" using my Milwaukee metal saw, but for the remaining 1/2" I needed to rely on my Sawzall. I went through Lenox, Dewalt, Diablo, and Milwaukee blades, each didn't last that long. I finally ponied up to the Milwaukee Torch Nitrous, which you showcased, I will admit these blades might take longer, not as fast, but for the fact I was able to finish 6 feet from one blade when I went through so many others speaks something of itself. I like how you are demonstrating each blade but you need to include the life of each of these blades, yes some may be cheap and cut fast but how long will they last? If I would've recorded my trials of cutting this plate I think it would have shown this but unfortunately I didn't. It is one thing to say something but it is another to show something. Who knows I still have some of this 1" scrap lying around, maybe I will try to make a video on all the different saw blades. In my case the Sawzall was the last resort, I didn't want to use it as I wanted the cleanest cut I could get, the 8" Milwaukee metal saw did great while going back and forth against a fence at 1/16" per pass but after 1/2" of metal too much friction remained to continue to cut. Now if I would've had a plasma cutter that could've done this (wish I could afford as well as a 3-phase converter) then this would have been an easy task. Although this took a good chunk of my day to accomplish, the end result was still pretty smooth.
So, in short order, the more teeth per inch [ TPI ] is better for metal, and placement of the initial cut is the key, regardless of the blade name. This is my takeaway from your test. More TPI is better for metal because it takes smaller bites and should last longer for the blades.
I know the problem is that because the saw is traveling in an arc because of how the test fixture is set up. If the saw starts touching the material that it is cutting it will bind before it is done with the cut.
Concern is durability/life. Pick 4 run repeated cuts(maybe 10) then time cut 10. Heard Diablo in past year has changed, not in a good way. Teeth breaking off.
In the last 3-6 months, Ian Rozell(car designer and fabricator) pointed out missing teeth after minimal use. He stopped buying them but didn't say what's the replacement. And a Canadian scrapper who buys Diablo blades and constantly complains about them.
Making comparisons of cutting speed with different TPI invalidates the test. If this is 1/4" wall tubing then 12 TPI would be ideal. As you increase TPI, it will cut slower all else being equal.
I'm getting ready to cut up a cast iron tub, and this made me feel pretty good about getting the Diablo blade. Thanks for a great video!
Glad to help!

Glad that you found the video helpful!
Reading the comments i can only commend your attitude, especially replying to criticism. refreshing to see a civilised and polite comment section :)
Thank you!
What about wear? And blade thickness/bendiness? I would need more information to decide which is best for me.
Great video and wonderful test
Thank you!
Diablo has the best blades. The End.
Not really, the Bosch blades are quite cheaper and seem just as good or better than diablo on saw saw blade
@@royalbridge Bosch owns Diablo
Thank you, if you ever need 6.51 seconds of my time, you've got it. You earned it with your comment lol
The End of the End. 😂😂
Diablo is junk
Good stuff. I got a car project coming up, and this helped a lot. Tha ks brotha.
Glad I could help
Good start! We need more videos like this. You may make it to the farm...
Thank you! I will keep 'em coming!
Your diagram at the end was fantastic. thank you
Glad it was helpful!

While using cutting oil does increase blade life it also increases the mess.
A quick spritz of brake cleaner or odorless mineral spirits cleans it up instantly.

I would have liked to see Irwin blades too but still a great video. Diablo is owned by Bosch so it is nice to see them compared.
Thank you, I will make sure to include Irwin blades when I revisit the topic.
Thanks man for taking your time to test these the way you did and post it, you rock
My pleasure!
For future comparisons, try to get same tpi for all of the brands that best fit the material you're cutting
Good point, however not all brands make the same tpi blades.
@@contractorscompass I think that’s intentional so that it makes it harder to compare. 👍
I would like to see what the blades look like afterwards
I will make sure to include what the blades look like after testing in future videos.
Can you add list of the tested blades (brand AND model)? With so many different styles/models, it is difficult to compare.
Will do!
I have added the list of the tested blades to the video description.
The price/time chart is missing scale for the 'price' axis ($/blade for example).
Thanks for letting me known!
idk if the fastest cutting determines the best blade. how many cuts will they make? how long can they make a cut until they overheat?
Definitely other factors to consider. However, I feel like if a blade doesn't cut quickly when it is new then it certainly doesn't get any better with more cuts.

I defiantly want to do a longevity test for the metal sawzall blades in the future!

I would argue that it depends on the thickness of the metal that you are cutting. The ticker the metal the lower the TPI that you want to have.
SHOW ME THE TEETH AFTER WARDS PLEASE!
Will do in future videos
bro your spooky all wrong
it’s supposed too touch the toll for it too cut properly
I know the problem is that because the saw is traveling in an arc because of how the test fixture is set up. If the saw starts touching the material that it is cutting it will bind before it is done with the cut.

Good idea! I have not heard that about diablo but I will look into it. Did they change their manufacturing process?
In the last 3-6 months, Ian Rozell(car designer and fabricator) pointed out missing teeth after minimal use. He stopped buying them but didn't say what's the replacement. And a Canadian scrapper who buys Diablo blades and constantly complains about them.
Put some oil on the blade
Should probably do multiple cuts and average the time. Sharpness isn't durability. (Holding an edge)
Good idea!

Good Point!
No hilti
Couldn't find any local to me
I’m not going to watch any of this video because Lenox are the best and I don’t even know if they’re on here.
Lenox was included in the video they preformed ok in the testing but defiantly were not the best.
dude gotta clamp the stuff properly man not safe and accurate if the bar is moving around like that
Thanks for the feedback! I will work on that in the future.
