Choosing the Right Chainsaw Chain
When you’re trying to cut through thick branches with your electric chainsaw, the type of chain you use makes a big difference. It’s not just about having a sharp chain; it’s about having the right kind of chain that’s designed for the job. Think of it like using the right tool for a specific task.
If you use a small screwdriver for a big bolt, it won’t work well. The same applies to chainsaw chains. We’ll explore the key features that make a chain great for tackling thicker wood, ensuring you get the best performance from your electric chainsaw.
Understanding Chain Pitch and Gauge
Two very important things to know about chainsaw chains are their pitch and gauge. These two measurements tell you a lot about how the chain will perform and if it will fit your chainsaw’s bar. Getting these right is the first big step to successfully cutting thicker branches.
What is Chain Pitch?
Chain pitch is the distance between the drive links on your chainsaw chain. Drive links are the parts of the chain that sit in the groove of your guide bar and connect the chain to the engine’s drive sprocket. It’s measured from the center of one rivet to the center of the next rivet.
The most common pitches for electric chainsaws are 3/8-inch and .325-inch. Sometimes you’ll see 1/4-inch pitch, but that’s usually for smaller saws. For cutting thicker branches, a larger pitch chain is generally preferred.
This is because a larger pitch means larger drive sprocket teeth, which can handle more power and torque, helping you cut through tougher wood more easily. A 3/8-inch pitch is often a good choice for electric chainsaws tackling thicker material because it provides a more aggressive cut.
What is Chain Gauge?
Chain gauge refers to the thickness of the drive links. This is the part of the chain that fits into the groove of your guide bar. Gauge is measured in inches and is usually something like .043, .050, or .058.
The gauge of your chain needs to match the groove in your guide bar. If the gauge is too thick, the chain won’t fit properly in the bar. If it’s too thin, it might wobble or not engage well with the bar groove.
For most electric chainsaws used for cutting branches, a .050-inch gauge is very common and works well. Always check your chainsaw’s manual or the markings on your guide bar to know the correct gauge.
Why Pitch and Gauge Matter for Thick Branches
When cutting thick branches, you need a chain that can bite into the wood efficiently and handle the load. A larger pitch (like 3/8-inch) often comes with larger cutters, which can remove more wood with each pass. This means less strain on your electric motor.
The gauge needs to be correct for your bar so the chain sits snugly and transfers power effectively.
Using a chain with the wrong pitch or gauge can lead to several problems. If the pitch is too small for the wood, the chain might bog down, making it hard to cut and putting extra stress on the saw’s motor. If the gauge doesn’t match the bar, the chain might not run smoothly, or worse, it could derail from the bar, which is dangerous.
For thick branches, a properly matched 3/8-inch pitch chain with the correct gauge for your bar is often the best bet for a smooth, efficient cut.
Chain Tooth Types for Cutting Power
Beyond just the size, the shape of the cutting teeth on your chainsaw chain also plays a big role in how well it cuts, especially through dense or thick wood. Different tooth designs are made for different cutting styles and types of wood.
Full Chisel vs. Semi-Chisel Chains
Chainsaw chains typically have either full chisel or semi-chisel cutters. Understanding the difference helps you choose the right one for tackling thick branches.
- Full Chisel Cutters: These cutters have sharp, square corners. They are very aggressive and designed for fast, clean cuts. They work wonderfully in clean, soft woods and can power through thicker pieces efficiently. However, they can dull more quickly if they hit dirt or rocks.
- Semi-Chisel Cutters: These have rounded corners. They are not quite as aggressive as full chisel but are more durable and less prone to dulling from accidental contact with hard objects. They are a good all-around choice but might not cut as fast through very dense, thick branches compared to full chisel.
Raker Depth and Its Impact
The raker is the part of the cutting tooth that sits in front of the actual cutting edge. The depth of the raker, also known as the depth gauge, controls how much wood the cutter removes with each pass.
A lower raker setting means the cutter bites deeper into the wood. This leads to faster cutting, which is great for thick branches. However, if the rakers are set too low, the chain can become very aggressive and hard to control, especially for beginners.
It can also lead to the chain jumping or causing kickback. A higher raker setting makes the chain cut shallower, which is safer and easier to control but slower. For cutting thick branches, you generally want a raker setting that allows for a good depth of cut without making the chain too difficult to manage.
Which Tooth Type for Thick Branches?
For cutting thick branches, a full chisel chain is often the preferred choice. Its aggressive nature allows it to cut through dense wood quickly and efficiently. The sharp corners bite into the wood, making rapid progress.
While it requires a bit more care and maintenance to keep sharp and avoid abrasive materials, the cutting speed it offers is invaluable when dealing with larger diameter branches.
If you’re a beginner or frequently encounter situations where your chain might accidentally hit dirt or small stones, a semi-chisel chain can be a safer and more forgiving option. It will still cut through thick branches, just perhaps not quite as quickly as a full chisel. For most users focused on efficiently cutting thick branches, leaning towards a full chisel chain with a properly set raker depth will provide the best results.
Matching the Chain to Your Electric Chainsaw Bar
You can’t just put any chain on your electric chainsaw. The chain needs to be the right size and type to fit your chainsaw’s guide bar perfectly. This is a critical step to ensure both safety and performance.
Chain Length (Number of Drive Links)
Chainsaw chains come in different lengths, measured by the number of drive links. The drive links are the small tabs on the bottom of the chain that fit into the guide bar’s groove and engage with the drive sprocket.
The length of the chain must match the length of your guide bar. For example, if you have a 16-inch guide bar, you’ll need a chain that is designed for a 16-inch bar, which means it will have a specific number of drive links. This number is usually listed in your chainsaw’s manual or sometimes stamped on the guide bar itself.
Using a chain that is too short or too long will prevent the saw from working correctly and can be very dangerous.
Chain Compatibility and Your Bar
It’s essential that the pitch and gauge of the chain you choose are compatible with your guide bar. As we discussed earlier, the pitch determines the spacing of the teeth, and the gauge determines the thickness of the drive links that fit into the bar’s groove.
If your bar is designed for a 3/8-inch pitch chain, you must use a 3/8-inch pitch chain. Similarly, if your bar’s groove is .050-inch wide, you need a chain with a .050-inch gauge drive link. The guide bar is essentially the track your chain runs on, and it’s engineered to work with specific chain dimensions.
Trying to force an incompatible chain onto a bar is a recipe for disaster, leading to poor cutting, damage to the saw, and serious safety hazards. Always check the specifications for both your chainsaw and your guide bar to ensure they are a perfect match for the chain you select.
Example: Fitting a Chain to a 16-Inch Bar
Let’s say you have an electric chainsaw with a 16-inch guide bar. You want to cut some thicker branches. You’ll need to find a chain specifically made for a 16-inch bar.
This chain will have the correct number of drive links. You also need to confirm the bar’s pitch and gauge. Most common electric chainsaws with 16-inch bars use a 3/8-inch low-profile pitch and a .050-inch gauge.
So, you would look for a chain that is described as “3/8-inch pitch, .050-inch gauge, for 16-inch bars.” This chain would likely be a full chisel type if you want maximum cutting power for thick branches.
Maintenance and Sharpness for Efficient Cutting
Even with the perfect chain type, if it’s not sharp and well-maintained, it won’t cut thick branches effectively. Regular care is key to keeping your chainsaw performing at its best.
Why Sharpness Matters
A sharp chain cuts wood cleanly and efficiently. Dull cutters require more force from the electric motor, leading to slower cuts and increased strain on the saw. This can cause the motor to overheat and may even shorten its lifespan.
For thick branches, a sharp chain is non-negotiable. It bites into the wood with ease, allowing the saw to do the work rather than you struggling to push it through. Dull chains are also more prone to kickback, a dangerous sudden upward and backward motion of the chainsaw.
How to Sharpen Your Chain
Sharpening a chainsaw chain involves using a round file of the correct size and a guide to maintain the proper angle. The angle is usually around 25-30 degrees for most chains. You’ll file each tooth on the chain, moving from the heel to the tip.
It’s important to file all the cutters to the same length and angle to ensure the chain cuts evenly. If some teeth are longer than others, the chain will cut unevenly, leading to poor performance and potential damage. Many hardware stores sell chain sharpening kits that include files, guides, and instructions.
It’s a skill that takes a little practice, but it’s very rewarding.
Checking and Adjusting Raker Depth
The rakers (depth gauges) need to be checked and adjusted periodically. If the rakers are too high, the chain won’t cut deeply enough, making it slow and inefficient, especially on thick branches. If they are too low, the chain will be overly aggressive and can cause dangerous kickback.
You can check the raker depth using a specialized tool, often called a raker gauge, or by using a flat file and a ruler. The depth is typically set to a specific measurement, which is often indicated in your chain’s manual or on the chain packaging. You can file down a high raker with a flat file.
This is a crucial step for maintaining the aggressive cutting performance needed for thick branches.
Lubrication is Essential
Your chainsaw chain needs proper lubrication to run smoothly and prevent wear. The oil lubricates the chain, the guide bar, and the sprocket. This reduces friction, dissipates heat, and prevents the chain from seizing up.
Electric chainsaws have an automatic oiling system, but you still need to ensure the oil reservoir is full and that the oil is flowing correctly. Check the oiler hole on the guide bar periodically to make sure oil is being distributed. If the oiler is clogged, the chain will not be lubricated, leading to rapid wear and overheating.
Regularly cleaning the bar groove and oiler hole will help ensure proper lubrication.
Real-World Examples and Scenarios
Let’s look at a couple of situations to see how choosing the right chain makes a difference.
Case Study: The Overwhelmed Gardener
Sarah had a thick, overgrown lilac bush that needed significant pruning. She had a basic electric chainsaw with a standard chain, good for light trimming. When she tried to cut the thicker branches, the chain kept bogging down.
It felt like she was forcing the saw through the wood. The motor sounded strained, and she made very slow progress. Frustrated, she looked up chainsaw chains online and learned about pitch and tooth types.
She switched to a chain with a 3/8-inch pitch and full chisel cutters, making sure the gauge and length matched her saw. The difference was immediate. The new chain bit into the wood easily, cutting through the thick lilac branches quickly and smoothly.
Her electric chainsaw handled the job with much less effort.
Scenario: Preparing Firewood
Mark needed to cut some fallen oak branches into firewood. These branches were quite thick, some up to 8 inches in diameter. He had an electric chainsaw with a 14-inch bar.
He initially used a chain that came with his saw, which was a semi-chisel type. It did the job, but it took him a while for each branch, and he noticed the chain was getting dull faster than he expected. He decided to try a full chisel chain, the same length and gauge, but with the more aggressive tooth design.
With the new chain, he found he could cut through the oak much faster. He also noticed the wood chips were bigger, indicating a more efficient cut. The key was the aggressive bite of the full chisel teeth on the dense oak wood.
Frequently Asked Questions
Question: What is the best chain type for cutting really hard, dense wood?
Answer: For very hard and dense wood, a full chisel chain is generally best. Its sharp, square corners are designed for aggressive cutting and can power through tough materials more effectively than semi-chisel chains.
Question: Can I use a chain with a different pitch than what my saw originally came with?
Answer: No, it’s not recommended. The pitch of the chain must match the pitch of your saw’s drive sprocket and the groove in your guide bar. Using the wrong pitch can cause damage, poor performance, and serious safety risks.
Question: How often should I sharpen my chainsaw chain?
Answer: You should sharpen your chain whenever you notice it starts to cut slower or requires more force. For general use, checking after every few hours of cutting is a good practice. Hitting dirt or rocks will require sharpening sooner.
Question: Is a longer bar always better for thick branches?
Answer: Not necessarily. While a longer bar can cut through thicker material in a single pass, it also requires a more powerful saw and can be harder to control. It’s important to match the bar length to your chainsaw’s motor power and your own comfort and skill level.
Question: What does “low-profile” mean for a chainsaw chain?
Answer: Low-profile chains, often with a 3/8-inch or .325-inch pitch and a narrower gauge, are designed for lighter-duty chainsaws, including many electric models. They are generally safer and easier to control, making them suitable for smaller saws and less demanding tasks like cutting branches.
Summary
When cutting thick branches with your electric chainsaw, the right chain type is crucial. Opt for a chain with a suitable pitch and gauge that matches your guide bar precisely. A full chisel chain often provides the aggressive cutting needed for dense wood.
Always keep your chain sharp and properly lubricated for efficient and safe operation.
