carbide coated chain.

Anybody use this stuff? Its in Baileys catolog. I believe its called injectasharp or something simular. It looks like regular chain with a carbide coating on the cutters.

does it say anything about how you sharpen it in the catalog? I guess if it is a coating, once it wares off, then you just have a normal chain?
I once talked with a guy from Oregon Saw Chain and they made carbide chains for the fire dept. use. They would use them once and then have to send it back to oregon for grinding. In an emergency, forced entry through a roof or wall it makes sense.

There are carbide chains with a chunk of tungsten carbide brazed onto the tooth and there are chains with carbide coated cutters(much cheaper). The coated cutter has a flash coat on the top of the tooth. You can still sharpen with a file. I had some of the coated stuff from another source 15yrs ago-I was't impressed.

Me too, in fact, I returned it for refund.

Hey bwalker, welcome.
The last time this came up, general consensus was that it was a specialty item for firefighters. Not much use for treemen because of the poor cutting ability. Even a couple firefighters said they preferred regular chain to the carbide. Compare it to having solid rubber tires on your truck. It will never wear out, but the ride sux.

If you do a search, you can probably find the last couple threads discussing this.
