The Essential Guide to Buying the Right Chainsaw Chain
A chainsaw is only as good as its chain. The chain does the hard work, cutting through wood quickly and efficiently. Choosing the right chain means smoother cuts, less frustration, and safer operation. This guide helps you pick the perfect replacement or upgrade for your chainsaw.
Key Features to Look For
When you shop for a new chain, three main features determine how it performs. Look closely at these specifications:
1. Pitch
The pitch measures the distance between the drive links—the little bumps that fit into the groove of your chainsaw bar. This measurement is crucial. If the pitch is wrong, the chain will not fit your saw or bar. Common pitches are 3/8 inch, .325 inch, and 1/4 inch. Always check your saw’s manual or measure your old chain to confirm the correct pitch.
2. Gauge
The gauge is the thickness of the drive links. This thickness must match the groove in your guide bar. Common gauges include .050 inches, .058 inches, and .063 inches. A chain that is too thick will bind up; one that is too thin will wobble. Matching the gauge ensures smooth movement and proper oiling.
3. Chain Length (Number of Drive Links)
The length is simply how many drive links the chain has. This must match the cutting length of your guide bar. If you buy a chain that is too short, it won’t wrap around the bar. If it’s too long, it won’t tension correctly. Count the drive links on your old chain, or check the recommended length for your bar size.
Important Materials and Construction
Chainsaw chains face extreme stress, heat, and friction. The material used directly impacts how long the chain lasts.
- Steel Alloy: Most quality chains use hardened steel alloys. This metal resists stretching and breaking under heavy loads.
- Cutter Material: The cutting teeth themselves often have extra-hard coatings. Look for chrome plating or carbide tips on premium chains. These coatings significantly increase resistance to dulling.
- Rivets and Links: The small pins (rivets) holding the chain together must be strong. High-quality chains use precisely manufactured, tightly fitted rivets to prevent the chain from separating during use.
Factors That Improve or Reduce Quality
Not all chains cut equally. Quality differences show up quickly in tough wood.
What Improves Quality (Look For This):
- Sharpening Angle: Chains designed for fast cutting often have a more aggressive angle (like 30 or 35 degrees).
- Lubrication Channels: Some chains have small grooves or holes designed to carry bar oil better along the entire length of the chain. This reduces friction and wear.
- Anti-Kickback Features: Bumpers or smaller cutter shapes reduce the chance of the saw violently kicking back toward the user.
What Reduces Quality (Avoid This):
- Soft Metal: Chains made from cheaper, softer steel dull very quickly, especially in dirt or knots.
- Poor Fit: If the pitch or gauge is slightly off, the chain wears out the bar groove rapidly.
- Inconsistent Manufacturing: Mass-produced, low-cost chains often have unevenly spaced cutters, leading to vibrations and poor cutting performance.
User Experience and Use Cases
Your intended use dictates the best chain type.
For General Yard Work and Firewood (Occasional Use): A standard, full-chisel or semi-chisel chain made of good steel alloy works perfectly. These are forgiving and easy to sharpen.
For Professional Logging or Hardwoods (Heavy Use): You need maximum durability. Look for full-chisel cutters with chrome plating. These cut extremely fast but require precise sharpening and excellent lubrication.
For Pruning or Small Saws: A smaller pitch (like 1/4 inch) and lighter gauge chain reduce the weight of the cutting assembly, making the saw easier to maneuver overhead.
Chainsaw Chain Buying Guide FAQ
Q: How often should I replace my chainsaw chain?
A: You should replace the chain when the cutters become too short to sharpen effectively, or if the chain stretches significantly and cannot be tensioned properly. Good chains last much longer than cheap ones.
Q: What is the difference between full-chisel and semi-chisel cutters?
A: Full-chisel cutters have a sharp, square cutting edge and cut the fastest in clean wood. Semi-chisel cutters have a slightly rounded edge; they cut slightly slower but handle dirt, sap, and knots much better without dulling as fast.
Q: Can I use a chain with a different pitch than my saw requires?
A: No. You cannot safely or effectively use a chain with the wrong pitch or gauge. It will damage your guide bar and clutch system.
Q: What is “chain stretch”?
A: Chain stretch is not the metal actually stretching. It means the rivets and links wear down, creating slack in the chain’s overall length, causing it to sag on the bar.
Q: Does the bar length dictate the chain length?
A: Yes. The bar length determines the necessary number of drive links. Always match the chain length to the guide bar you are using.
Q: How important is proper chain lubrication?
A: It is extremely important. Oil prevents friction, which stops the chain from overheating and wearing out prematurely. Always check your oil reservoir before cutting.
Q: Where do I find the correct pitch and gauge for my saw?
A: Check the side of your existing guide bar, or consult the owner’s manual for your specific chainsaw model. These specs are always listed there.
Q: Are carbide-tipped chains worth the extra cost?
A: If you frequently cut very hard, knotty, or dirty wood, yes. Carbide tips stay sharp significantly longer than standard steel, reducing downtime for sharpening.
Q: What does “anti-kickback” mean?
A: Kickback is when the saw violently jumps back toward the operator. Anti-kickback features are safety additions, usually smaller, shallower cutters, designed to reduce this dangerous reaction.
Q: Should I buy an OEM (Original Equipment Manufacturer) chain or aftermarket?
A: Aftermarket chains often offer better value and performance upgrades (like better steel). If you match the correct pitch, gauge, and link count, a high-quality aftermarket chain is usually a great choice.
