File life

[Crofter]

Hey Oregon Engineer; wouldn't it be possible for the odd tooth to get through the quench and tempering process and be left a little on the hard side. I have noticed a few teeth hard in the bottom from the initial grinding. I use an old file to do the first strokes and clean out the gullets on a new chain. You sure can harden them with a grinder.

I file some RS chains here as well, and it is not as common on these as on Oregon, there is a big difference in the cutters, some is just slightly harder, hard to miss unless you file by hand when new.

I tried to file with Dremel, I wanted to test this for a while. Oregon sells the bits. I actually liked it. Not as hard as i thought, very important to keep all clean. The largest benefit is the chains that has been filed wrong, that has too much of the cutter left in the bottom

Had a Stihl chain on a 044 that had much harder teeth on one side.
