Which Metal Sawzall (Reciprocating Saw) Blade is The Best? Diablo/Milwaukee/Lenox/Bosch 

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!

What about wear? And blade thickness/bendiness? I would need more information to decide which is best for me.

Your diagram at the end was fantastic. thank you

Diablo has the best blades. The End.

Thanks for the effort but that was a very sketchy set up. Guard should be tight to the material being cut to ensure all energy is used to cut not make the material jump about. And what is more important than speed is longevity of blade. You were running the saw way o fast for not adding any lubricant and that kills the teeth quickly. We cut out cast iron plumbing pipe, usually 4" and lots of 2"-2 1/2" galvanized daily. For what its worth the Diablo Carbide is worth the $15 per blade but you have to take care of it. Have a helper spraying lubricant (oil or WD-40) & the blade will last 20 times longer. Slow down the cut also. Yes, it's nice to pull the trigger at full speed but HEAT/FRICTION kills these. 1 blade per job or 6 ? You do the math. We use Diablo but Milwaukee is comparable in our real day to day experience. Thank you for the comparison

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?

The Diablo isn't 50-100x better they have 50-100x the life. Those cheap blades after a few cuts get dull then your popping in a fresh one. One of the amped would be like getting 50-100 of the cheap ones.

Pretty good video. Succinct and clear. Thanks for posting.

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.

Amped Diablo is the king of saw blades...

dude gotta clamp the stuff properly man not safe and accurate if the bar is moving around like that

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.

bro your spooky all wrong it’s supposed too touch the toll for it too cut properly

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.

For future comparisons, try to get same tpi for all of the brands that best fit the material you're cutting

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.

The price/time chart is missing scale for the 'price' axis ($/blade for example).

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.

I would want to see each blade pictured after one (or ten ) cuts but after the same length of use. How long they last is equally important as speed of a small cut

I would like to see what the blades look like afterwards

Reading the comments i can only commend your attitude, especially replying to criticism. refreshing to see a civilised and polite comment section :)

Good start! We need more videos like this. You may make it to the farm...

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.

Should probably do multiple cuts and average the time. Sharpness isn't durability. (Holding an edge)

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.

Put some oil on the blade

Carbide blades are not designed or made to cut faster. They are designed/made to cut thicker/harder steel and should last longer than simple steel blades.

SHOW ME THE TEETH AFTER WARDS PLEASE!

Thank You for helping me decide what blades to buy.

Can you add list of the tested blades (brand AND model)? With so many different styles/models, it is difficult to compare.

Good stuff. I got a car project coming up, and this helped a lot. Tha ks brotha.

Great video and wonderful test

No hilti

Thanks man for taking your time to test these the way you did and post it, you rock

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.
