Chainsaw Sharpening Tools
Identify the chain before choosing a round file
Use the chain maker’s code and sharpening chart to choose a file that fits the cutter.
Read the maker and chain code
Look for the chain identification given in the chain manual or stamped on the chain. If a replacement chain is fitted, identify that chain before using a file size from the saw’s original equipment list.
Check the exact pitch designation
A standard 3/8-inch chain and a low-profile 3/8-inch chain can use different cutter geometries and file sizes. Keep the complete designation and chain series together when comparing guides and replacement files.
Match the diameter in the maker’s chart
Read the round-file diameter assigned to your chain. Check the diameter on the file package separately from the working length or pack quantity. If you already have a holder, check its supported file diameter and retention method.
