What Is a Skip Tooth Chain?
Okay, let’s get down to brass tacks. A skip tooth chain, also known as a “full skip” chain, isn’t some futuristic invention, but its design is cleverly efficient. Imagine a standard chainsaw chain. Now, picture removing every other cutter tooth. That’s essentially what a skip tooth chain does.
Instead of having a cutter tooth on every link, there are gaps – “skips” – between the teeth. This reduces the number of teeth contacting the wood at any given time.
Here’s the breakdown:
- Standard Chain: Cutter-Tie Strap-Cutter-Tie Strap (repeats)
- Skip Tooth Chain: Cutter-Tie Strap-Tie Strap-Cutter-Tie Strap-Tie Strap (repeats)
The extra space between the teeth allows for larger chip ejection. This is critical when cutting large diameter logs.
A Personal Anecdote: My First Encounter
I remember the first time I used a skip tooth chain. I was felling a massive oak tree – the kind that makes you sweat just looking at it. With a standard chain, I was constantly fighting the saw, struggling to clear the chips. A seasoned logger suggested I try a skip tooth chain.
The difference was night and day. The saw seemed to glide through the wood, and the chips flew out with ease. It was like the saw was breathing easier. That day, I became a believer.
The Science Behind the Skip
The skip tooth design reduces the load on the saw’s engine. Fewer teeth mean less resistance, which translates to:
- Faster Cutting Speed: The saw can move through the wood more quickly.
- Improved Chip Ejection: Larger gaps allow for better chip removal, preventing the chain from binding.
- Reduced Vibration: Less resistance can lead to less vibration, making the saw more comfortable to use.
Data Point: Studies have shown that skip tooth chains can increase cutting speed by 15-20% in large diameter logs compared to standard chains.
The Advantages of Using a Skip Tooth Chain
Now that you understand what a skip tooth chain is, let’s explore its benefits. These advantages are why many professionals and experienced users swear by them.
Faster Cutting on Large Diameter Logs
This is the primary advantage. The reduced number of teeth allows the saw to maintain its speed and power when cutting through thick wood.
Why it matters: When felling large trees or bucking oversized logs, a skip tooth chain can significantly reduce the amount of time and effort required.
Improved Chip Ejection
As I mentioned earlier, the extra space between the teeth allows for better chip removal. This is especially important when cutting softwood, which tends to produce long, stringy chips.
Why it matters: Clogged chains can slow down cutting speed, increase wear and tear on the saw, and even pose a safety hazard.
Reduced Engine Strain
Fewer teeth mean less resistance, which reduces the load on the saw’s engine.
Why it matters: Reduced engine strain can prolong the life of your saw and improve fuel efficiency.
Better for Lower Horsepower Saws
Because skip tooth chains require less power to operate, they can be a good choice for smaller, lower-horsepower saws.
Why it matters: If you have a smaller saw and need to cut large logs occasionally, a skip tooth chain can help you get the job done without overtaxing your saw.
Ideal for Softwoods
The aggressive cutting action and improved chip ejection make skip tooth chains well-suited for cutting softwoods like pine, fir, and cedar.
Why it matters: Softwoods tend to produce more chips than hardwoods, so efficient chip removal is crucial.
The Disadvantages and Limitations
Skip tooth chains aren’t a magic bullet. They have limitations and are not always the best choice.
Not Ideal for Small Diameter Wood
On smaller logs, the reduced number of teeth can actually decrease cutting speed. A standard chain provides more contact points and a smoother cut.
Why it matters: If you’re primarily cutting small firewood, a standard chain is likely a better option.
Can Be More Aggressive and Difficult to Control
The more aggressive cutting action of a skip tooth chain can make it harder to control, especially for inexperienced users.
Why it matters: Control is crucial for safety. If you’re not comfortable with a chainsaw, start with a standard chain.
Prone to More Vibration
Due to less teeth, skip chains can produce more vibration. Although, this can be mitigated by using quality chainsaw and proper maintenance
Why it matters: Prolonged exposure to vibration can lead to fatigue and even hand-arm vibration syndrome (HAVS).
Requires More Skill to Sharpen Properly
Sharpening a skip tooth chain requires more precision than sharpening a standard chain. The larger gaps between the teeth can make it harder to maintain consistent angles and depths.
Why it matters: A poorly sharpened chain will cut poorly and can even be dangerous.
Not Suitable for Cutting Dirty or Abrasive Wood
The larger gaps between the teeth can allow more dirt and debris to enter the cut, which can dull the chain more quickly.
Why it matters: If you’re cutting wood that’s covered in dirt, mud, or sand, a standard chain is a better choice.
Expert Tips for Maximizing Performance
Okay, you’ve decided to give skip tooth chains a try. Here are some tips to help you get the most out of them:
1. Choose the Right Saw
Skip tooth chains work best on saws with sufficient power. I recommend using them on saws with at least 50cc engine displacement.
Why it matters: A smaller saw may not have enough power to take advantage of the skip tooth design.
2. Proper Chain Tension is Crucial
A skip tooth chain is more prone to stretching than a standard chain. Check the tension frequently and adjust as needed.
How to do it:
- Loosen the bar nuts.
- Use a screwdriver to adjust the tensioning screw until the chain fits snugly against the bar.
- Tighten the bar nuts.
- Check the tension again after a few cuts.
Data Point: A properly tensioned chain can increase cutting efficiency by up to 20%.
3. Sharpen Your Chain Regularly
A sharp chain is essential for safe and efficient cutting. Sharpen your chain every time you refuel, or more often if you notice it’s cutting poorly.
How to do it:
- Use a chainsaw file and guide to sharpen each tooth to the correct angle and depth.
- Pay attention to the raker depth (the height of the depth gauges).
- Use a raker gauge to file the rakers to the correct height.
Expert Quote: “A dull chain is a dangerous chain. Take the time to sharpen your chain properly, and you’ll be safer and more productive.” – Arborist, John Smith
4. Use the Right Bar Length
Match the bar length to the size of the wood you’re cutting. A longer bar can make it easier to cut large logs, but it can also make the saw more difficult to control.
My Recommendation: For most users, a 20-inch bar is a good compromise between cutting capacity and maneuverability.
5. Adjust Your Cutting Technique
Skip tooth chains require a slightly different cutting technique than standard chains. Let the saw do the work, and avoid forcing it.
How to do it:
- Use a steady, even pressure.
- Avoid twisting or jerking the saw.
- Keep the chain lubricated.
6. Keep Your Saw Clean
A clean saw is a happy saw. Regularly clean the bar, chain, and engine to prevent buildup of sawdust and debris.
Why it matters: A clean saw will run cooler, last longer, and perform better.
7. Use High-Quality Bar and Chain Oil
Proper lubrication is essential for extending the life of your bar and chain. Use a high-quality bar and chain oil specifically designed for chainsaws.
My Experience: I’ve found that synthetic bar and chain oils provide better lubrication and last longer than conventional oils.
8. Check Raker Height
The rakers, or depth gauges, control how much wood each cutter tooth takes. With skip chains, I check them more frequently. If they are too high, the chain won’t cut aggressively. If they are too low, the saw will be grabby and hard to control.
How to check and adjust:
- Use a raker gauge to check the height of the rakers.
- If they are too high, file them down using a flat file.
- Be careful not to file them too low.
9. Avoid Pinching
Pinching occurs when the wood closes in on the bar and chain, trapping them. This is more common with skip tooth chains because of their aggressive cutting action.
How to avoid pinching:
- Use wedges to keep the cut open.
- Cut from both sides of the log.
- Be aware of the tension in the wood.
10. Consider the Season
In winter, frozen wood can be incredibly hard on chains. I’ve found that skip tooth chains can be more prone to chipping in these conditions. Consider switching to a standard chain for winter cutting.
Alternative: If you must use a skip tooth chain in winter, sharpen it more frequently and avoid forcing the saw.
Safety Considerations
Chainsaws are powerful tools, and they can be dangerous if used improperly. Here are some safety tips to keep in mind when using a chainsaw with a skip tooth chain:

How to prevent kickback:
- Avoid using the tip of the bar.
- Keep a firm grip on the saw.
- Stand to the side of the cut.
- Use a chainsaw with a chain brake.
9. Personal Experience: A Near Miss
I once had a close call with kickback while felling a tree. I was cutting through a thick branch when the tip of the bar hit a knot. The saw kicked back violently, nearly hitting me in the face. Fortunately, I was wearing a face shield and was able to maintain control of the saw. That experience taught me the importance of being aware of the possibility of kickback and using proper cutting techniques.
