why?

This might have been addressed in earlier post but I just came across this. Why does Stihl say use a 13/64" file on a 3/8 chain and Husqvarna/Oregon and maybe others say use a 7/32" file is there a huge difference between them I have used the 13/64 Swiss file from Stihl and it works great is there a advantage/disadvantage?

This topic has just been covered.
Both file diameters will work good.

Take a look here.

I think this may be the reason for specifying 13/64 for Stihl chain. The cutter is quite long on the Stihl and comes up very close to the raker. It is just a little difficult to get a 7/32 file down in for the first sharpening. Especially so if you are using some of the file guides. Either one will work for hand sharpening.

There are two schools of thought about the smaller file. A smaller file can file the much harder Stihl cutter faster, however, a small file may tend to be a hook enabler. Given that you were a good filer in the first place, you could get by with almost any size file.
I like the 7/32" as they are good cleaning out the gullets. The larger file may also give a bit more directional control when filing since it may tend to lay in the cutter better.
It all comes down to the finish product and not neccessarily the file you used.

13/64 on non-Stihl chains?

I searched this before and also read where the 13/64 file allows you to file the cutter back further w/o contacting the straps.

Any reason to NOT use a 13/64 on other 3/8 chain? That would be my question. If it extends cutter life, why not?

13/64 files are $12 a dozen at my dealer and that works for me since I've not read of any negatives from a 13/64 w/ the right guide. Guess other files may be cheaper elsewhere, but it wont' be enough to make a difference to me.

i've found that the 13/64 file gave the chain too much hook (especially on a new chain) and when i was cutting dry wood i would lose the corners way too fast. if you are cutting green cedar all the time than it probably wouldn't matter.
i read in that earlier thread that you wouldn't get enough hook at the end of the chains life with a 7/32 file but i've gone right to the line and have still made the chips fly
