Oregon 40459 Round File, 2-Pack, 5/32"

There are a handful of file sizes that are each meant to sharpen different saw chains, determined by the Pitch of the saw chain. In order to determine the correct file for your needs, you would need to locate the Pitch of your saw chain by using one of the methods mentioned above: finding the code on drive links, etching on bar, or directly measuring the saw chain. 

If you have determined the pitch of your saw chain, this table above can be used quite universally with most brands of saw chain. 

However, there are some key notes to be careful of when determining the right file:

• Round files go only with round grind teeth. If you notice straight sections and multiple angles on the cutting edge, check the specific filing instructions for that chain model.
• Regular and Low Profile Saw Chain require different size files. 3/8” and 1/4” Pitch chains come also in Low Profile (Picco) versions, which have lower cutters and take a smaller file.
• Manufacturer recommendations vary from time to time, meaning it's always worth it to check your specific saw chain’s manufacturer recommendation. ***Sometimes intermediate sizes, 11/64” and 13/64”, are recommended instead of the XX/32” sizes.***
