The Oregon T50 VersaCut? saw chain is a high-performance 3/8 in Low-Profile? chain for arborists and orchardists who use lightweight saws. Longer cutter top-plates offer longer cutting life. The low-vibration, semi-chisel cutters provide an aggressive cutting edge with a forgiving sharpening profile. This chain fits several saws including Stihl? 009, 010, 011, 012 and 015.
