    Just checking to see if these files are the right ones i'm using for my stihl chains. I hope someone can confirm this stuff.

    MS200T- 3/8"PM, .050 = 5/32" file

    MS260- .325 RSC, .063 = 3/16" file

    MS260- 3/8" RSC, .050 = 13/64" file

    MS261- 3/8" RSC, .050 = 13/64" file

    are those the right files i'm using for these saws?
    thankz

    Welcome X 2

    7/32 files will work fine with the 3/8 RSC if you can't find 13/64 readily. 7/32 can be a bit tricky to start on the first sharpening, but other than that there's no noticeable difference.

    Take Care

    I find 13/64 to work the best on regular 3/8 Stihl chain for the vast majority of its life. Towards the end 7/32 works well.

    In the Bailey's catalog, most of the .375 Oregon chain (yeah...it's actually .367) lists as using a 7/32 file. Is Stihl chain different? What am I going to lose if I stick with 7/32 files with the Stihl RSC chain I'll be running?

    I use Oregon 7/32 on any Stihl 3/8 chains i have to sharpen with no ill effects. Haven't got round to getting the right file as virtually all my chains are Oregon.

    Don't you want to drop to a smaller, not larger size when getting down to the last of the tooth? The new-tooth file size starts cutting into the drive link and tie straps when the tooth is at its last.

    Yep, this what I use as well, 7/32 for 3/8 RSC, seems to stay sharper longer :D

    This should be the case. The larger file gives you less hook, less hook lasts longer but cuts a little bit less aggressively.

    Nothing

    Don't even worry about it. Chain will be just as sharp and pull just as well.

    Take Care

    For your consideration,

    Since the file radius difference is only a nominal 1/128 or .008 inches I really doubt it makes a difference. Either will cut a hook just fine and stay out of the chassis if you know what you're doing.

    .325 20"

    Someone help me out here please. I have found that the 3/16 file is too small for the 20" .325 chains when used with the file guide that locks to the file itself. I have to use a 13/64 for this. Has anyone else run into this?:chainsawguy:

    1. what do you mean "too small" in terms of the file? A file that is too small would generally cut too much of a hook?

    2. Is your file attachment designed to work with 3/16" files?

    Mirek,

    Welcome to AS, I see you have some very, very nice saws listed :)

    So unless you want to spend the money on 70cc,80cc,90cc saws
    and maybe bigger. Take your file information and run from AS
    and never come back!!

    If you decide to stay, don't ever say you were never warned :hmm3grin2orange:

    yeah the guide I'm using is an Oregon model for a 3/16 file, and on my 14" MS 170 it does fine. But on the 20" the file doesn't catch all of the tooth. It doesn't go deep enough to put the right edge on the side cutter, just files the top plate and the upper half of the side cutter.

    It's funny you said that because I do just the opposite. To me starting with 13/64 doesn't get the top of the cutter sharp unless you old up on the file. Towards the end of the chains life if I keep using 7/32 I don't seem to get enough hook to the cutter and so I then switch to 13/64 to finish it off. Probably not the textbook way or anybody else's, but I've had good luck doing it that way.

    check that! I use a 5/32 on the MS170. The 3/16 works fine on my 18" setup for the MS290, but the 20" setup seems to have bigger teeth, but all my 20" chains are Stihl brand and are .325, 20", .63gauge and 81links.

    I ran into that using the guide with a 13/64 file. I finally gave up and ditched the guide and now do all my filing free hand. It does take practice and by no means do I claim to be a pro. As long as I can keep the chain cutting the way it is supposed to I consider it a success. And no I won't mention how many chains I went through trying to learn how to file!!!!!

    I have been sawing for 25 years and I am still no pro at free hand filing! LOL! I guess I'll just keep using the old benchtop grinder on the 20" stuff! Just hate to waste so much valuable tooth material.
    Thanks for the info though.
