There are some good points made through this about both the K-12 and the chainsaw. My dept. has 1 chainsaw and 7 K-12 saws. All the K-12's are set up for different things. Some for wood, some for steel, and some for concrete. It all depends what you train with. Some prefer the chainsaw because of the weight difference, but i prefer the K-12. It has always been reliable and gotten the job done. Use what you are more comfortable with and train with it.

P.S.- For the comment made about there is no way to stop the blade on a K-12, I do not agree with. When you are cutting, all you need to do is take your finger off of the throttle and bury your blade.

All of our rigs carry both, but the chain-saw is by far the most utilized.

Perhaps bury it in your leg...

I think his point is that there is no mechanical safety device to stop the blade, and I have to agree that the chainsaw is faster and safer.

I imagine most of you have seen the video of the roof being vented with a sledge faster than with an axe. (For all you "traditionalists").

Also hoping that the previous 2 posters realize this thread is older than some of the nut bags that frequent these here forums.

what is the best blade for the chain saws that won't clog up or dull fast?

You use a blade on your chain-saw? No wonder it clogs.

K-12

In my opinion I prefer the K-12 to the chainsaw. I'm a former mason and hodd carrier and we'd use'm all the time to cut anything in front of us. They are heavy but..... they can take a beating. Chainsaws are a one trick pony and require a ton of maintenance so for smaller departments it's more bang for the buck to purchase one K-12 with some cut all blades.

Chainsaws are used for cutting tree limbs that fall on cars and similar situations. On my shift you will carry the K-12 to the roof, and if you can't take the weight you belong on an engine. Other shifts at my department have taken the chainsaw and sometimes it worked and sometimes they had problems. Try cutting through 2-3 layers of shingles with a chain and see how far you get.

In addition you don't need to worry about what the depth gauge is set on or if the chainsaw even has one. A k-12 will not allow too deep of a cut if you miss a rafter and don't pull up on the saw. The blade cover allows only about 4 inches of cutting, and for all the people who don't understand how you stop the blade, you bury it in the roof.

Stihl MS 460 Rescue chain saw

This saw was mentioned in the thread. We use one and it works great! It replaced our old cutters edge chainsaw which worked great to, but the Stihl service center is next door to us. Just make sure you use it with the Rapid duro rescue chain or "RDR" (costs about $175). As for Chainsaw vs K12, I prefer a chainsaw for many reasons. One of which is that a chainsaw is light enough that you can keep your weight supported with your legs, but a K12 will cause you to bend over because of the weight and short reach of the blade.

If your having to remove shingles before you cut a hole, your chainsaw has the wrong chain on it. Buy the right chain (Bullet, Raptor, or Stihl RDR) and you firefighters will spend very little time on the roof!
