Description
Oregon 20" Professional Full Chisel Chainsaw Chain – 3/8" Pitch, .050" Gauge, 70 Drive Links
Get professional-grade cutting performance with this Oregon 20" Full Chisel Chainsaw Chain. Built for loggers, arborists, and tree care professionals running high-performance saws, this chain combines aggressive full-chisel cutters with Oregon's proprietary cutter technology for fast, efficient, and precise cutting. Premium OCS-01 steel, corrosion-resistant blued cutters, and the LubriTec™ lubrication system provide the durability needed for demanding professional cutting applications.
Chain fitment depends on your guide bar specifications—not just chainsaw model or bar length.
Always verify your current chain specifications:
- 20" Bar Length
- 3/8" (.375") Pitch
- .050" (1.3 mm) Gauge
- 70 Drive Links
Model fitment alone does not guarantee compatibility. Many chains and guide bars look similar but use different pitch, gauge, and drive link combinations.
Important: This is a professional full-chisel chain. Full-chisel chains are designed for aggressive cutting performance and should be used by operators familiar with their cutting characteristics and proper chainsaw safety practices.
If you're unsure, contact us with your chainsaw model number, guide bar information, and current chain number, and we'll help verify the correct replacement before you order.
