The Stihl 20" RAPID™ Micro 3 (RM3) Saw Chain in .325" pitch, .063" gauge, 81 drive links is built for pros who need smooth cutting, less kickback, and longer edge life in real-world jobs. This chain uses Stihl’s low-kickback design so you get safer starts without losing power. RM3 keeps all the cutting muscle of a regular RM chain but adds features that reduce the chance of sudden kickback.
This chain has a semi-chisel cutter profile that’s tougher on junk wood, frozen or dirty rounds—it dulls slower than full-chisel types and is easier to sharpen on the job. The taller profile drive links add weight and help it stay stable and true during heavy cuts, especially on mid- to large-displacement saws. Its Oilomatic® lubrication grooves channel bar oil straight to the rivets and cutters, cutting friction, heat, and chain stretch so you don’t have to re-tension as often. At the factory, Stihl pre-stretches the chain so break-in is shorter and adjustments are minimal once you get it running. Fit is dead simple for compatible saws with 20" bars using .325" pitch, .063" gauge, and 81 drive links. Use it for felling, bucking, trimming, storm cleanup—anywhere you need reliable, steady cutting. You’ll feel less vibration, fewer snags, and fewer surprises—even when you’re pounding through rough wood all day.
