Swiss made OEM chainsaw chain from Stihl. Stihl saw chain is made for the most demanding cutting conditions and is loaded with professional features. Stihl chain has Oilomatic drive link lubrication slots, which funnels oil directly to the rivet to reduce wear. Stihl chain is also pre-stretched at the factory, which helps eliminate excess adjustments during break in periods. 26RM3 is part of the Stihl Micro 3 series. This chain has reduced kickback and low vibration features. 26RM3 has semi-chisel cutters which work cut relatively fast, and stay sharp much longer in abrasive conditions as compared to chisel chain.
