STIHL 26RM3-81 Oilomatic Rapid Micro 3 Saw Chain 20in - Low Kickback

Our review of the STIHL 26RM3-81 Oilomatic Rapid Micro 3 saw chain finds it best suited to professionals and serious homeowners who need a durable, low-kickback chain for a 20in guide bar. The bottom line: this chain delivers the balance of cutting performance and reduced kickback risk that many operators want, while fitting typical 20in chainsaw setups that accept 0.325in pitch and 0.063in gauge chains. Performance is solid for felling, bucking and limbing, and the semi-chisel cutters make maintenance easier under regular use.

Key Features

• Low-kickback design: The RM3 is the low-kickback version of the Rapid Micro chain, reducing the risk of kickback injury for safer operation.
• Compatibility: With a 0.325in pitch and 0.063in gauge it fits chainsaws built for a 20in guide bar and 81 drive links, making replacement straightforward when specs match.
• Semi-chisel cutters: The semi-chisel tooth profile holds its edge longer than full-chisel designs during normal work, lowering sharpening frequency.
• Heavier profile: A taller, more massive chain profile suits larger displacement engines and withstands demanding professional use.
• General-purpose performance: Intended for felling, bucking and limbing, the RM3 balances cutting speed and control for full-time operators.

Who It's For

The RM3 chain is aimed at forestry professionals, landscapers and agricultural users who run chainsaws for extended periods and need a low-kickback chain that still cuts well. It is also a good choice for nonprofessional users who work in demanding conditions and want a chain that stays serviceable longer between sharpenings.

Users who must match exact fitment should verify their chainsaw requires 0.325in pitch, 0.063in gauge and 81 drive lengths for a 20in guide bar before purchasing. Casual users with smaller saws or those who prefer the peak cutting speed of full-chisel chains may want a different profile.
