Specification Value MPN 79571126816 Brand STIHL SKU / Size 33RS-72 Pitch 3/8 inch Gauge 0.050 inch Drive Links 72 Guide Bar Compatibility 20-inch guide bar Weight 16 oz Color Black Category Chainsaw Chains 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.
