18" Chainsaw Chain 3/8 050

Overview

STIHL RAPID Super 18" Chainsaw Chain (79571126815) is designed for chainsaw accessories applications requiring fast, aggressive cutting performance in hard or frozen wood conditions.

Technical Features

• Full-chisel cutter design — razor-edged, square-cornered cutter geometry minimizes chain friction, delivering a smooth and clean cut in hard or frozen wood.
• 66 drive links on an 18" bar length — correctly matched pitch (3/8") and gauge (.050") ensure proper tensioning and compatibility with appropriate STIHL guide bars.
• Cutter and tie strap design engineered for reduced vibration — lowers operator fatigue during extended cutting operations without sacrificing the aggressive cutting profile of a full-chisel chain.
• Faster cutting rate than RAPID Master (RM) chain — the RS series is rated by STIHL as a higher-speed cutting chain, improving productivity in demanding applications.
• Excellent plunge-cutting efficiency — the cutter geometry supports controlled plunge cuts, expanding versatility for felling and bucking tasks.

Applications

• Cutting hard or frozen wood where a full-chisel chain maintains superior performance over semi-chisel alternatives.
• Felling, limbing, and bucking operations requiring fast stock removal rates.
• Plunge-cutting applications such as pocket cuts in felling work.
• Professional and serious homeowner use where chain speed and cutting efficiency are prioritized — note that this chain requires careful, precise sharpening and consistent maintenance to sustain performance levels.
