Technical Features
- Full-chisel cutter geometry: Razor-edged, square-cornered cutter shape minimizes chain friction, delivering an exceptionally smooth and clean cut in hard or frozen wood.
- Reduced-vibration cutter and tie strap design: Engineered cutter and tie strap geometry lowers vibration levels during operation, reducing operator fatigue during extended cutting sessions.
- 3/8-inch pitch: Industry-standard pitch measurement ensures compatibility with a wide range of 3/8-pitch drive sprockets and guide bars.
- 0.050-inch gauge: Precise gauge specification matches the drive link thickness to compatible guide bar groove tolerances for stable chain tracking.
- 72 drive links: Drive link count sized specifically for 20-inch guide bar applications, ensuring correct chain-to-bar fit.
- Superior cutting speed vs. RM chain: The RAPID Super (RS) full-chisel design cuts faster than STIHL RAPID Micro (RM) chain under equivalent operating conditions.
- Plunge-cutting efficiency: Chain geometry supports both standard crosscutting and plunge-cutting techniques, expanding versatility for bore-cut and felling applications.
Applications
- Crosscutting and felling hardwood timber where fast, clean cuts are required.
- Cutting frozen wood where square-cornered full-chisel cutters maintain edge performance in low-temperature conditions.
- Plunge-cutting and bore-cut techniques used in limbing, sectional felling, and arborist work.
- Replacement chain for chainsaws equipped with a 20-inch guide bar using 3/8-inch pitch, 0.050-inch gauge drive components.
Note: The RAPID Super chain requires careful sharpening and regular maintenance to sustain peak cutting performance. Full-chisel cutters are more sensitive to dulling from contact with dirt or debris compared to semi-chisel designs.
