Quick Answer
Certain chainsaw chains are better for hardwood due to their specialized design, which allows them to efficiently cut through dense, hard wood fibers.
Chainsaw Chain Design for Hardwood
When cutting hardwood, chainsaw chains with a larger, more aggressive tooth design are preferred. These chains have a higher tooth count, typically 3/8 inch pitch with 84 or 88 teeth per 30 inches. This design enables the chain to make deeper cuts and reduce binding, which can be a major issue when cutting hardwood.
Tooth Geometry and Hardness
Chainsaw chains designed for hardwood often have a more aggressive angle and a harder tooth material, such as high-nickel or cobalt, to increase durability and tooth life. Harder teeth also tend to retain their sharpness longer, reducing the need for frequent sharpening. A tooth hardness of 58-62 HRC (Rockwell Hardness Scale) is typical for hardwood chains.
Chain Speed and Stroking Patterns
To optimize cutting performance when felling or bucking hardwood, chainsaw operators should maintain a higher chain speed (approximately 20-25 m/s) and use a more aggressive stroking pattern. This helps to reduce the risk of kickback and allows the chain to cut cleanly through the wood fibers. By understanding the specific design requirements for chainsaw chains when cutting hardwood, operators can improve their efficiency, reduce their risk of injury, and produce higher-quality firewood for seasoning and burning.
