It's odd how you start the cut with the tip.

Anyone here ever operated one of these suckers?
 
It's just carbide tipped chain. Not at all good for production work like that. Really only good for emergency used in those kinds of conditions.

I know burl cutters that tried it and tossed it. Cost a small fortune to loop a big double headed mill. The carbide lasts but the straps and drivers wear out just as fast a normal chain would, and therefore it doesn't warrant the cost. If the rest of the chain was built to last as long as the carbide it would be a different thing.
 
Carbide is not the magic cure all a lot of people think it is . The stuff will crack like an egg if it hits something hard enough .

What would or could be bad on a saw is breaking a cutter which would embed a tooth in the wood .As the rest of the cutters hit the broken tooth they would come out like machine gun bullets .

I remember seeing the roof of a saw shed where they hit a pole insulator in a log using an inserted blade .It looked like a strafing run from a WW2 fighter plane .:O
 
I invested in one carbide , as G.F.B says the wear ... plus the teeth actually do dull .... diamond wheels will sharpen so it can't be done in the field ...
 
That's the Univent they're using, which is a ported 372XPG 75 cc model. supposed to be the power of a well done modded saw, according to Greg at Bailey's.

I wouldn't mind having a carbide chain for root cutting, or low cuts.....but know that it's not fast even when fresh, and can break, needs a diamond wheel to sharpen. Won't stand up to repeated hitting of rocks. Uhh, I reckon a green wheel would work, if the carbide is similar to what's on stump grinder teeth. I don't know if anyone makes anything like a green wheel for saw chain.
 
I imagine they use a diamond or CBN wheel .Besides that carbide uses a differant angle than regular high speed steel ,that is to say on regular cutting tools .That said no doubt on a rescue chain the same would hold true .
 
Actually Gerry, while that chain is carbide, it is shaped differently than normal saw chain.
I checked one of those out in this hardware store once. Apparently it really does last a long time. The cutters are squared off even more than chisel cut chain.

It is designed to run loose also. In the movie you can see it dangling off the bar.
Good for fireman I guess or the contractor.

See all that smoke from the barrel and concrete?
No wonder fireman have such a high rate of cancer breathing that kind of smoke from that stuff. Toxic.

Every firefighter I know smokes. With the stuff they're exposed to, tobacco smoke is like a breath of fresh air.
