Buying Guide
Key purchase considerations help buyers select the best 20 inch chain for their saw and tasks. Factors include pitch, gauge, drive links, compatibility, and safety considerations. Below are multiple perspectives to help with decision making:
- Pitch and gauge compatibility: 3/8″ pitch paired with .050″ or .063″ gauge is common for 20 inch bars. Verify your guide bar’s groove width and the sprocket type to ensure the chain fits and functions correctly.
- Drive links and bar length: Drive link counts (72, 80, 81) must align with the bar length and model. An incorrect count can lead to poor tension, binding, or uneven cutting.
- Chisel design and cutting performance: Full chisel vs semi-chisel influences sharpening frequency, debris handling, and cut speed. Full chisel typically cuts fast but can dull quicker in dirty wood, while semi-chisel resists dulling in debris and provides smoother operation over time.
- Safety and kickback: Some chains carry kickback risk, especially in aggressive entry cuts or improper handling. Training and adherence to safety guidelines are essential when using kickback-prone chains.
- Lubrication and pre-tensioning: Some models advertise pre-stretching or lubrication benefits that can reduce maintenance time and improve cutting efficiency. Consider chains with these features if available for your saw.
- Brand and model compatibility: Popular brands such as Husqvarna, Stihl, and Oregon often list compatible bar models. Cross-reference your chainsaw’s manual and bar stamping to select a chain with the correct pitch, gauge, and drive-link count.
- Replacement frequency and work type: For heavy-duty use or frequent cutting, a high-quality chain with durable steel and heat treatment may offer longer life and steady performance, even in tough wood or dirty conditions.
- Training and safety gear: Always operate with proper PPE (gloves, eye/face protection, hearing protection) and be aware of kickback zones. If new to kickback-prone chains, seek instruction before use.
