Chainsaw Chains: A Deep Dive

Let’s start with the basics. Chainsaw chains aren’t just loops of metal; they’re precision-engineered cutting tools designed to work in harmony with your saw. The two most critical measurements are pitch and gauge, and understanding them is the first step to choosing the right chain.

Pitch: The Spacing Between Rivets

The pitch of a chainsaw chain refers to the distance between any three consecutive rivets divided by two. It’s measured in inches, and the most common pitches are .325 and 3/8.

• .325 Pitch: This pitch is generally found on smaller to mid-sized chainsaws. Chains with a .325 pitch offer a good balance between cutting speed and smoothness. They tend to vibrate less than 3/8 chains, making them more comfortable for extended use.
• 3/8 Pitch: This pitch is more common on larger, more powerful chainsaws. 3/8 chains are more aggressive and can remove more material per cut, making them suitable for felling large trees and processing thick logs.

Data Point: A study by the Forest Engineering Research Institute of Canada (FERIC) found that chainsaws equipped with 3/8 pitch chains showed a 15-20% increase in cutting speed when felling trees over 16 inches in diameter compared to those with .325 pitch chains.

Gauge: The Drive Link Thickness

The gauge of a chainsaw chain refers to the thickness of the drive links, which are the parts of the chain that fit into the groove of the chainsaw bar. The gauge is measured in inches, and the most common gauges are .050 and .058.

• .050 Gauge: This is a thinner gauge, and it’s often found on smaller to mid-sized chainsaws. Chains with a .050 gauge create a narrower kerf (the width of the cut), which means the saw requires less power to cut through the wood.
• .058 Gauge: This is a thicker gauge, and it’s more common on larger chainsaws. Chains with a .058 gauge are more durable and resistant to stretching, making them suitable for heavy-duty applications.

Why Gauge Matters:

Using the wrong gauge chain can be dangerous and damage your chainsaw. If the chain is too thin, it will wobble in the bar groove, leading to inaccurate cuts and potential kickback. If the chain is too thick, it won’t fit in the bar groove at all.

Stihl Chains: A Cut Above the Rest?

Stihl is renowned for its high-quality chainsaws and accessories, and their chains are no exception. Stihl chains are made from high-grade steel and are designed for durability, sharpness, and performance.

Unique Features of Stihl Chains:

• Oilomatic Lubrication System: Stihl chains feature a patented Oilomatic lubrication system that channels oil directly to the chain rivets, reducing friction and wear.
• Pre-Stretched Chains: Stihl pre-stretches its chains during manufacturing, which minimizes stretching during initial use and reduces the need for frequent adjustments.
• Chromium-Plated Cutters: Stihl cutters are chromium-plated for increased hardness and wear resistance, ensuring long-lasting sharpness.

Stihl Chain Types: Understanding the Options

Stihl offers a variety of .325 and 3/8 chains to suit different needs and applications. Here’s a look at some popular options:

• .325″ Rapid Micro (RM): This is a low-vibration chain ideal for general-purpose cutting. It’s known for its smooth cuts and ease of sharpening.
• .325″ Rapid Super (RS): This is a high-performance chain designed for professional use. It features a square-cornered cutter for aggressive cutting and fast chip removal.
• 3/8″ Rapid Micro (RM): Similar to the .325 RM, this chain offers smooth cuts and reduced vibration but with the added cutting power of a 3/8 pitch.
• 3/8″ Rapid Super (RS): This is Stihl’s top-of-the-line chain for professional loggers and arborists. It’s designed for maximum cutting speed and efficiency.

Choosing the Right Chain: A Practical Guide

Now that you understand the basics of chain pitch, gauge, and Stihl’s chain offerings, let’s talk about how to choose the right chain for your specific needs.

Factors to Consider:

• Chainsaw Model: The most important factor is the chainsaw model. Your chainsaw’s manual will specify the correct pitch and gauge for your saw. Never deviate from these specifications.
• Type of Wood: The type of wood you’ll be cutting also influences chain selection. Softer woods like pine and cedar are easier to cut and can be handled by either .325 or 3/8 chains. Hardwoods like oak and maple require more aggressive chains, such as the 3/8 Rapid Super.
• Cutting Application: The type of cutting you’ll be doing also matters. For general-purpose cutting and limbing, a .325 Rapid Micro chain is a good choice. For felling large trees and bucking thick logs, a 3/8 Rapid Super chain is more appropriate.
• User Skill Level: If you’re a beginner, I recommend starting with a .325 Rapid Micro chain. It’s easier to control and less prone to kickback than a 3/8 chain.

Here’s a simple table to help you decide:

My Personal Experiences: Chain Selection in Action

Over the years, I’ve learned a lot about chain selection through trial and error. Here are a few examples:

• Firewood Processing: When I’m processing firewood, I primarily use a Stihl MS 261 with a .325 Rapid Micro chain. It provides a good balance of cutting speed and efficiency for bucking smaller logs.
• Felling Large Trees: When I need to fell a large oak or maple tree, I switch to my Stihl MS 462 with a 3/8 Rapid Super chain. The added power and aggressiveness of the 3/8 chain make the job much easier and faster.
• Limbing: For limbing, I often use a smaller Stihl MS 170 with a .325 Rapid Micro chain. The lightweight and maneuverability of the saw, combined with the smooth cutting of the .325 chain, make it ideal for this task.

Pro Tips: Chain Maintenance and Sharpening

No matter how good your chain is, it won’t perform well if it’s not properly maintained. Here are some pro tips to keep your Stihl chain in top condition:

• Sharpen Regularly: A dull chain is not only inefficient but also dangerous. Sharpen your chain every time you refuel your saw, or more often if you’re cutting dirty or abrasive wood.
• Use the Right Tools: Invest in a good quality chainsaw file and a depth gauge. Using the wrong tools can damage your chain and make it difficult to sharpen properly.
• Maintain Proper Depth Gauge Settings: The depth gauges (also known as rakers) control how much the cutters bite into the wood. If the depth gauges are too high, the chain won’t cut effectively. If they’re too low, the chain will be too aggressive and prone to kickback.
• Clean Your Chain Regularly: Sawdust and pitch can build up on your chain, reducing its performance and lifespan. Clean your chain regularly with a brush and solvent.
• Lubricate Properly: Use a good quality bar and chain oil to keep your chain properly lubricated. Insufficient lubrication can cause excessive wear and tear on the chain and bar.
• Check Chain Tension: Regularly check the chain tension and adjust as needed. A loose chain can derail and cause damage to your saw.

Step-by-Step Guide: Chainsaw Chain Sharpening

Sharpening your chainsaw chain is a crucial skill for any chainsaw user. Here’s a step-by-step guide:

1. Secure the Saw: Place your chainsaw in a vise or clamp it securely to a workbench.
2. Identify the Cutting Angle: Determine the correct cutting angle for your chain. This information can be found in your chainsaw’s manual or on the chain packaging.
3. File Each Cutter: Using a chainsaw file that matches the diameter of your chain’s cutters, file each cutter at the correct angle. Make sure to maintain a consistent angle and pressure.
4. Check Depth Gauges: Use a depth gauge tool to check the height of the depth gauges. If they are too high, file them down to the correct height.
5. Test Your Work: After sharpening, test your chain on a piece of wood. The chain should cut smoothly and efficiently.

Industry Insights: Trends and Innovations

The chainsaw industry is constantly evolving, with new technologies and innovations emerging all the time. Here are a few trends to watch:

• Battery-Powered Chainsaws: Battery-powered chainsaws are becoming increasingly popular, offering a quieter and more environmentally friendly alternative to gas-powered saws.
