How to identify your chainsaw chain

To identify your current chain, locate its specifications, in the form of numbers stamped on your guide bar. These are the pitch, gauge and drive link count (DL).

You can view examples of pitch in our chainsaw chain categories and products our by looking at our chain, bar and sprocket ID guide.

Pitch is the measurement between drive links, gauge is the thickness of the drive links (which sit in the guidebar groove) and drive links is the measurement used to ensure a good fit on your guidebar.

Other considerations are to select a cutter profile suited to the job you are undertaking. Full-chisel teeth give maximum cutting speed when sawing fresh, clean wood whilst semi-chisel cutters stay sharper longer when cutting dirty or dry timber.
