While many blades have coatings, Diablo’s coating is robust and resists accumulating pitch from cutting sappy framing lumber. But as far as recip saw blades go, well, I use what I’ve been using: mostly bi-metal demo blades. And, as is usually the case, whack through a few spikes (most recip blades I’ve used will gobble up smaller nails for a while but not 16s which I usually cut removing stud walls and strapping) and enough teeth break off that the blade is slowed significantly.
Now had I not seen this video with my own eyes I’d be hard pressed to write the following: Diablo’s carbide tipped, coated Demon blades look like they’ve made a quantum leap in demolition production. The recip blades cut 120 nails—with the same teeth—in a row and still knock 2-by out of the way like it’s barely there.
What’s more, one blade costs about 9 bucks versus the the 10 blades they used to compete against—costing almost 50 smackers. Even if this is only half true it’s still twice as devilishly good. I like the coating and deep gullets for other stuff like cutting deck posts and plowing through built-up assemblies like a roof deck. Seeing red.
