STIHL 3689 005 0074 Chainsaw Chain – 18" Bar | .325" Pitch | .063" Gauge | 74 Drive Links – 26RM3
The STIHL 3689 005 0074 saw chain is a top-tier Rapid Micro 3 (26RM3) chain built for power, precision, and safety. With a .325" pitch, a thick .063" gauge, and 74 drive links, it’s designed to fit 18-inch guide bars on mid-size STIHL chainsaws used for firewood cutting, storm cleanup, and forestry work.
The 26RM3 chain features semi-chisel cutter teeth, making it more forgiving in dusty or dirty wood and easier to maintain than full chisel chains. It also includes low-kickback safety features, meeting ANSI B175.1 standards, so you can cut with confidence.
