The Chainsaw Chain: More Than Just a Loop of Metal
Before we delve into the different types of chainsaw chains, it’s essential to understand the anatomy of what makes a chainsaw chain. It’s more than just a loop of metal; it’s a precisely engineered cutting tool.
Understanding the Key Components
A chainsaw chain consists of three primary components:
- Cutters: These are the teeth that do the actual cutting. They come in different shapes and sizes, which we’ll explore in detail later. The sharpness and design of the cutters directly impact cutting speed and efficiency.
- Tie Straps: These connect the cutters and provide stability to the chain. They also help to carry lubricating oil to the cutters.
- Drive Links: These fit into the guide bar groove and are driven by the chainsaw’s sprocket. The number of drive links determines the chain’s length and is crucial for proper fit.
The Cutting Action: How Chainsaw Chains Work
The cutters on a chainsaw chain don’t just saw through wood; they actually shave it away. Each cutter has a side plate and a top plate that are sharpened to create a precise cutting edge. As the chain rotates around the guide bar, the cutters scoop out small chips of wood.
The depth gauge, also known as the raker, controls the amount of wood each cutter removes. If the depth gauge is too high, the cutter won’t bite into the wood effectively. If it’s too low, the cutter will take too big of a bite, causing the chainsaw to bog down and potentially kickback.
Types of Chainsaw Chains: Finding the Right Fit
Now that we understand the basics of chainsaw chain anatomy, let’s explore the different types of chains available. Each type is designed for specific applications and offers unique performance characteristics.
1. Full Chisel Chains: Aggressive Cutting Power
Full chisel chains are known for their aggressive cutting action and speed. They feature square-cornered cutters that slice through wood quickly and efficiently. I often reach for a full chisel chain when I’m felling large trees or bucking clean logs.
- Pros:
- Fastest cutting speed
- Ideal for clean wood
- Efficient for high-volume cutting
- Cons:
- Dulls quickly in dirty or abrasive conditions
- More prone to kickback

- Best For: Experienced users cutting clean, softwood or hardwood in professional logging or tree felling situations.
My Experience: I remember one time I was helping a friend clear some land for a new cabin. The area was overgrown with mature pine trees, and we needed to fell them quickly to make way for construction. I equipped my chainsaw with a full chisel chain, and it made short work of those trees. The aggressive cutting action allowed us to fell and buck the logs in record time.
2. Semi-Chisel Chains: A Versatile All-Rounder
Semi-chisel chains offer a balance between cutting speed and durability. They feature rounded cutters that are less aggressive than full chisel chains but more resistant to dulling. I often use a semi-chisel chain for general-purpose cutting, such as pruning, limbing, and firewood preparation.
- Pros:
- Good cutting speed

4. Specialty Chains: Tackling Unique Challenges
In addition to the standard chain types, there are also specialty chains designed for specific applications:
- Ripping Chains: These chains are designed for cutting wood lengthwise, along the grain. They have a different cutter geometry that allows them to slice through wood more efficiently in this direction. I use a ripping chain when I’m milling lumber with my chainsaw.
- Carving Chains: These chains have a narrow profile and a small radius nose, which allows for precise and intricate cuts. They’re used by chainsaw carvers to create sculptures and other artistic pieces.
- Concrete Cutting Chains: These chains are equipped with carbide-tipped cutters that can cut through concrete, stone, and other abrasive materials. They’re used in construction and demolition applications.
Data Point: Chainsaw Kickback Statistics
According to the Consumer Product Safety Commission (CPSC), chainsaw kickback is a leading cause of chainsaw-related injuries. Kickback occurs when the tip of the chainsaw bar contacts an object, causing the saw to suddenly thrust backward towards the operator. Low-profile chains and chains with kickback-reducing features can significantly reduce the risk of this dangerous event. Studies have shown that using a chain with kickback-reducing features can decrease the likelihood of kickback by as much as 50%.
Decoding Chainsaw Chain Specifications: Pitch, Gauge, and Drive Links
Understanding chainsaw chain specifications is crucial for ensuring compatibility and optimal performance. The three key specifications are pitch, gauge, and drive link count.
Pitch: The Spacing Between Links
Pitch refers to the distance between any three consecutive rivets on the chain, divided by two. It’s measured in inches and is typically expressed as 0.325″, 3/8″, or 0.404″.
- 0.325″ Pitch: Common on smaller chainsaws and offers a good balance of cutting speed and durability.
- 3/8″ Pitch: The most common pitch size, used on a wide range of chainsaws.
- 0.404″ Pitch: Typically found on larger, professional-grade chainsaws and offers maximum cutting power.
How to Determine Pitch:
The easiest way to determine the pitch of your chain is to consult your chainsaw’s owner’s manual or look for markings on the guide bar. You can also measure the pitch manually using a ruler or caliper.
Gauge: The Thickness of the Drive Links
Gauge refers to the thickness of the drive links, which fit into the guide bar groove. It’s measured in inches or millimeters and is typically expressed as 0.043″, 0.050″, 0.058″, or 0.063″.
- 0.050″ Gauge: The most common gauge size, used on a wide range of chainsaws.
- 0.058″ Gauge: Often found on larger chainsaws and offers increased durability.
Why Gauge Matters:
Using the correct gauge is crucial for ensuring that the chain fits properly in the guide bar groove. If the gauge is too small, the chain will be loose and may derail. If the gauge is too large, the chain won’t fit in the groove at all.
Drive Link Count: The Chain’s Length
The drive link count refers to the number of drive links on the chain. This number determines the chain’s length and is crucial for ensuring that it fits properly on your chainsaw.
How to Determine Drive Link Count:
The easiest way to determine the drive link count is to consult your chainsaw’s owner’s manual or count the number of drive links on your old chain.
My Tip: When replacing a chainsaw chain, it’s always a good idea to bring your old chain with you to the store. This will help you ensure that you’re purchasing the correct replacement.
Data Point: The Importance of Proper Chain Selection
A study conducted by the Forest Engineering Research Institute of Canada (FERIC) found that using the correct chainsaw chain for the application can increase cutting efficiency by as much as 20%. The study also found that using a dull or improperly sharpened chain can reduce cutting efficiency by as much as 50%. This highlights the importance of selecting the right chain and maintaining it properly.
