How to Know What Size File for Chainsaw

Determine the file size for your chainsaw by checking the chain pitch; common sizes are 5/32″, 3/16″, or 7/32″, aligned with the chain specifications.

Keep your chainsaw in top condition with the right size file for sharpening. Discover the simple steps to finding the perfect match and maintaining your tool’s performance effectively.

Understanding Chainsaw Chain Measurements

Before you can select the proper file size for your chainsaw, you need to understand the basic measurements associated with chainsaw chains. Chainsaw chains come in different pitch and gauge sizes, which determine the size of the file required for sharpening.

The pitch of a chain refers to the distance between three consecutive rivets divided by two, whilst the gauge is the thickness of the drive link where it fits into the bar groove. It is vital to know these measurements as they will guide you in choosing the correct file size.

Step-by-Step Guide to Choosing the Right File Size

  1. Find Your Chainsaw Chain Specifications: Start by checking the user manual of your chainsaw to find the pitch and gauge of your chain. If you don’t have the manual, look for the specifications stamped on the chain itself.
  2. Match the Chain Pitch with the File Diameter: Once you have determined the pitch of your chain, you can match it with the correct file diameter. Use the table below as a reference to find the corresponding file size for your chainsaw’s pitch.
  3. Consider the File Handle: It’s not just about the file itself; having a proper file handle can enhance your grip and accuracy when sharpening the chain.

  • Right Angles: Be sure to file at the correct angle as recommended in the chainsaw’s user manual, usually between 25 to 30 degrees.
  • Consistent Stroke: Apply even pressure and maintain a consistent stroke count for each tooth to ensure an even sharpening.
