Mid-range chainsaws—such as Husqvarna 455 Rancher, Stihl MS311/MS391, and similar 18"–20" saws—are versatile tools for firewood processing, property maintenance, and heavier trimming. These saws typically use a .050" gauge chain, which provides a robust balance of strength, stability, and durability for demanding cutting tasks.
Choosing the right .050" gauge chainsaw chain ensures smooth cutting performance, longer component life, and a safer cutting experience. This guide explains what to look for and highlights a reliable chain option optimized for mid-range saws.
What Does .050" Gauge Mean?
The gauge refers to the thickness of the drive links—the part of the chain that fits into the guide bar groove. A .050" gauge is thicker and stronger than a .043" gauge, making it better suited to heavier saws and larger guide bars where durability and stability matter.
Common Applications for .050" Gauge Chains
- Wood splitting and firewood cutting
- Storm cleanup and fallen timber processing
- Heavier pruning and limb removal
- Frequent homeowner or light professional use
Recommended .050" Gauge Chain Option
An excellent choice for mid-range saws with a 20" or similar guide bar is:
3/8" LP · .050" Gauge · (Drive Link Count Varies by Bar Length) · Chainsaw Chain
This chain is engineered with chrome-plated cutters and reinforced rivets for durability, delivering strong cutting performance while reducing wear over time.
How .050" Gauge Chains Perform
- Supports higher loads and frequent use without rapid wear
- Maintains stability at higher cutting speeds
- Handles larger wood and more abrasive conditions better than thinner gauges
Installation and Maintenance Tips
- Always confirm pitch, gauge, and drive link count before installation
- Set and check proper chain tension regularly for safety and performance
- Sharpen the chain when cutting performance drops
- Replace the chain before significant wear compromises performance
Conclusion
Choosing a high-quality .050" gauge chainsaw chain tailored to your mid-range saw increases cutting efficiency, improves stability, and extends the life of both the chain and your tool. A well-matched chain helps you handle demanding tasks with confidence and safety.
