The Oregon M80 SpeedCut Saw Chain is ideal for arborists and property owners who want top performance. Oregon SpeedCut narrow kerf cutting systems are more efficient since this require less power from the saw than standard cutting systems. The low-vibration Micro Chisel cutters have small-radius working corners for excellent performance and easy maintenance. A reshaped cutting surface allows you to get faster, easier cuts. This 20",.325" pitch chain has compatible fit with Husqvarna H30 80.
