20" Chainsaw Chain 325 063

Overview

The 20" Chainsaw Chain 325 063 (79571134868) is designed for chainsaw cutting applications requiring a high-performance, full-chisel saw chain compatible with 20" guide bars.

Technical Features

• Full-chisel cutter geometry — Razor-edged, square-cornered cutter shape minimizes chain friction, producing a smooth and clean cut in hard or frozen wood.
• Aggressive cutting design — Full-chisel profile delivers faster cutting speeds compared to semi-chisel (RM) chains, maximizing productivity during demanding cutting tasks.
• Reduced-vibration cutter and tie strap design — Engineered cutter and tie strap geometry lowers vibration levels significantly, reducing operator fatigue during extended use.
• Excellent plunge-cutting efficiency — Chain geometry supports both conventional cutting and plunge-cut applications, expanding versatility on the job site.
• 66 drive links — Correct link count ensures precise fit on compatible 20" guide bars with .325" pitch and .063" gauge specifications.
• Genuine OEM STIHL component — Manufactured to STIHL factory standards, ensuring dimensional accuracy and material consistency for reliable performance.

Applications

• Felling, bucking, and limbing in hardwood and frozen wood conditions where maximum cutting speed is required.
• Professional and demanding residential chainsaw use on 20" bar-equipped STIHL saws specifying .325" pitch and .063" gauge chain.
• Plunge-cutting operations such as pocket cuts and storm damage cleanup.

Note: RS (RAPID Super) chain cuts faster than RM chain but requires careful and regular sharpening and maintenance to sustain peak cutting performance. Maintain square cutter corners and correct file angles to preserve full-chisel efficiency.
