Chainsaw Chain 20 Inch .325 Semi-Skip (Optimal Tips for Pro Logging)
Understanding the Chainsaw Chain: 20-Inch .325 Semi-Skip
Before diving into the cost analysis, it’s essential to understand the specifics of the 20-inch .325 semi-skip chain. This type of chain is a popular choice for a reason: it strikes a balance between cutting speed, durability, and chip clearance.
What the Specs Mean
- 20-Inch: This refers to the effective cutting length of the chainsaw bar. A 20-inch bar is suitable for felling trees up to around 36 inches in diameter, though experienced loggers can handle larger trees with proper techniques.
- .325 Pitch: The pitch is the distance between three rivets divided by two. A .325 pitch is a common size, offering a good balance between speed and strength. It’s ideal for medium-sized chainsaws and general-purpose cutting.
- Semi-Skip: This refers to the arrangement of cutting teeth. A semi-skip chain has fewer teeth than a full-complement chain, creating larger gaps between the teeth. This improves chip clearance, which is especially beneficial when cutting softwood or dirty wood.
Why Choose a Semi-Skip Chain?
Semi-skip chains are particularly advantageous in the following situations:
- Cutting Softwood: Softwoods like pine and fir produce larger chips that can quickly clog a full-complement chain. The wider gaps in a semi-skip chain allow for better chip ejection, preventing the chain from bogging down.
- Cutting Dirty or Knotty Wood: When cutting wood that contains dirt, bark, or numerous knots, a semi-skip chain is more resistant to clogging and binding.
- Larger Chainsaws: Semi-skip chains are often used on larger chainsaws (50cc and up) because they require less power to operate than full-complement chains. This can improve fuel efficiency and reduce wear and tear on the saw.
My Personal Experience
I remember one particularly challenging job where we were felling old-growth pine in a heavily forested area. The trees were massive, and the wood was incredibly resinous. We initially tried using full-complement chains, but they kept getting clogged with sap and sawdust, slowing us down considerably. Switching to semi-skip chains made a world of difference. The improved chip clearance allowed us to cut much faster and more efficiently, ultimately saving us time and money.
