Buying Guide: Key Considerations For 20 Inch Chains
- Compatibility: Verify pitch, gauge, drive link count, and bar length against your chainsaw’s manual and bar stamp.
- Plantary safety: Look for low-kickback designs and ensure you have training and PPE for kickback-prone chains.
- Durability vs. cost: Higher-grade steel and coatings improve wear life but may cost more; balance your budget with maintenance needs.
- Maintenance needs: Some chains are easier to file (semi-chisel vs full-chisel); consider your sharpening setup.
- Intended use: For dense hardwood or high-debris conditions, a tougher chain with robust rivets and heat treatment can reduce downtime.
