Product Description
5 Pack 20 Inch Chainsaw Chain .325" Pitch .050" Gauge 81 Drive Links
- 【German Steel Durability】Crafted from premium DIN-certified German steel (HRC 58-62) with 30μm industrial hard chrome plating—resists abrasion from bark, ice, and grit. Lab-tested to retain sharpness through 10,000+ cuts on oak and maple, outperforming standard chains by 150% lifespan.
- 【Semi-Chisel Debris Defense】Precision heat-treated semi-chisel teeth (quenched at 850°C) feature angled top plates and rounded edges—self-cleaning design expels sawdust instantly. Proven to cut 30% faster in resinous pine and sand-embedded logs than full-chisel chains, with 90% less kickback risk.
- 【Hardened Chrome Rivets】Aerospace-grade carbon steel rivets with chrome-nickel coating endure 10,000 RPM stress. Field-tested in -20°C to 50°C conditions—80% less stretch after 8-hour logging sessions than standard chains.
- 【ANSI/CSA Certified Safety】Passed ANSI B175.1-2012 kickback tests (≤13° deflection angle) and CSA Z62.3 chain retention standards. Features patented anti-snap grooves and triple-reinforced tie straps to prevent chain derailment.
