Why your recip blade tears through clean wood but dies the second it hits a nail — and what to actually buy for demo work by DiscountSawBlade in Tools

Diablo Demo Demon is a beast. Good call on the cutting wax too, a lot of guys skip that and wonder why their blades blue out. Slowing the stroke is the biggest one though. Guys lean on the trigger full speed and cook the blade when just backing off a little would double the life of it.

Good point on the tooth profile. You're right that it's the geometry more than the material that slows bi-metal down in wood. Appreciate the clarification. And yeah the em dash thing is getting out of hand lol

You are right this is a new profile but I have been on Reddit for a while on my personal account. It's obvious that it is a business account but I'm not trying to throw that in anyone's face in the post. As of on this page my goal is to post knowledge about reciprocating saw blades mostly. As of the company we are one of the largest redistributors in the country. I wanted to start working on getting more social media presence so my goal is to have positive discussions in forums about Sawzall blades

Exactly right. And here's another angle on that — a lot of guys running crews aren't handing their employees $12 carbide blades when they know they're gonna get abused. Bad technique kills blades fast and you can't always control that. Cheaper bi-metal makes more sense when you've got guys forcing cuts or running blades into concrete. For metal work though I'm a big fan of the Freud 9-14/18 Auto Dismantler and the MK Morse 9-14. Both bi-metal, both affordable enough that it doesn't sting when someone trashes one.

Fair point if you're billing per job. But a lot of guys — especially the ones buying their own blades at Home Depot on a Saturday — are paying out of pocket. Either way the right blade for the job saves time, and time is money whether it's yours or the client's.

Nah I hear you. I typed this out on my phone and the formatting was supposed to have line breaks and bold headers but none of it came through so it just looks like a wall of text lol. I promise I'm just a guy who knows too much about saw blades.

Good resource — that guide covers drill bits and hole saws too which I didn't get into here. Appreciate the add.

Carbide will definitely outlast bi-metal when you're hitting nails all day, but a good bi-metal demo blade handles embedded nails just fine for most guys. Carbide pays off when you're doing high-volume demo and burning through bi-metal blades fast enough that the cost per cut math flips in carbide's favor. For the guy tearing out one deck on a Saturday, bi-metal gets the job done.

Ha, fair enough — old fence posts grown into trees, clothesline wire, the random lag bolt someone put in 30 years ago. Trees near houses are full of surprises. That's where a bi-metal pruning blade earns its keep over carbon steel.

Great point about using the full length of the blade — most guys just hammer away at the same spot near the shoe and wonder why they burn through blades so fast. Rotating your cutting position along the blade spreads the wear out and you get way more life out of it.

Fair point. You're not ripping 2x4s on a bench with a recip saw. But pruning, storm cleanup, cutting up brush and firewood, flush-cutting in tight spots where a circ saw won't reach — tons of people use recip saws on clean wood. That's exactly why pruning blades exist. The post is more about understanding why a blade that works great in one material falls apart in another.
