Sawzall blades?

What sawzall blades do you use? Are the expensive blades ($15 per blade) worth buying? I buy the Irwin 10 pack of (medium thickness) metal blades for $13.00. They are the cheapest I can find and I burn through blades quickly. Would a $15 blade last longer, like as long as a 10 pack of cheap blades? Does the saying "you get what you pay for" apply here? And has anyone used the blades that are made specifically for cast iron? if so, reviews?

Morse fire and rescue blades is my choice. They are tough. Ive never bent one. I guess because who has time to keep changing blades when someone is trapped in a burning car.

What do you use the blades for?
I cut car exhausts for the cats and also sometimes cut up the cars themselves

I use the 6" and 9" Milwaukee 10 TPI Torch Sawzall Blade

I purchase 100 at a time >> Saves a lot of money over buying 5 or 10 at a time
I have tried the expensive diamond grit blades a couple times BUT did not get the results I was hoping for so I have stuck with these

I've been using the Sawzall a lot over the past month. Mostly for nail cutting in tight spaces during the demolition phase of the project. The blade tends to get bent right where it attaches to the saw and that's where it fails. First you get a stress crack and then a few minutes later it breaks off. They all do it ......

The Sawzall saves so much on labor that the blade cost is insignificant. I usually just charge them off to the job like i would a 2 x 4 or a pound of nails.

The Diablo blades are good as well as the Milwaukees. The Irwins are okay .... nothing special. If you're cutting cast iron it would probably be better to go to a 4" angle grinder. A Sawzall isn't the best tool for that job.

Lenox blades are the best by far, they are a bit more expensive but worth it. dewalt blades are the worst

The lenox ( 5 pk/27.50) are good blades. They don't break as often but they get dull areas and slow the job down to a crawl. Where the rest of the blade is good you hate to throw em' away so you keep using them.

Locally, they've been phasing the Lenox out in favor of the lower cost Diablo

I use the Milwaukee Torch blades as well. They're thick enough they don't bend if you get a little careless with them and cut well for me (mostly car exhaust, but use for just about anything in the salvage yard). I tried a pack of Kobalt blades from Lowe's once, I couldn't get rid of those **** things fast enough.

I use Diablo's but the company buys them buy the pack of 500, so the cost is significantly less. Maybe there's a 100 or 200 pack you could get?

I use Milwaukee Torch. I have tried others. I would say the worst I ever tried were Harbor Freight. Let it bounce out of the cut one time and that blade folds like a pretzel.

To increase blade life I use cutting oil and also don’t go full speed with it.

Ok. Ford vs chevy for sure. I guess I will have to find out for myself. Milwakee, Diablo, and Lenox. It seems no one has tries the cast iron blade
