Stihl 325 Chainsaw Chains (5 Expert Picks for Full Chisel Cuts)

Versatility is the name of the game when you’re talking chainsaws, and the .325 chain pitch is a real workhorse in that department. It’s not as aggressive as a .404 chain, which you’d typically find on larger milling saws, nor is it as fine as a 3/8″ low profile, often used on smaller limbing saws. The .325 strikes a beautiful balance, offering a respectable cutting speed and enough robustness for tackling a variety of tasks, from felling smaller trees to bucking firewood. As someone who’s spent countless hours in the woods, I’ve come to appreciate a good .325 chain for its all-around performance.

Full chisel chains boast square-cornered cutters that slice through wood fibers with ruthless efficiency. They’re designed for speed and maximum wood removal, making them ideal for experienced users who prioritize cutting performance. However, they also demand a bit more respect and attention. They dull faster in dirty conditions and require more precise sharpening.

In this article, I’m going to share my top five picks for .325 pitch full chisel chainsaw chains, specifically tailored for Stihl chainsaws. These are chains I’ve personally used and abused in the field, and I’ll be diving deep into their strengths, weaknesses, and ideal applications. We’ll go beyond just listing model numbers and talk about the nuances that make each chain unique.

Understanding the .325 Chainsaw Chain

Before we dive into the specific models, let’s make sure we’re all on the same page about what a .325 chainsaw chain actually is.

• Pitch: The pitch of a chain refers to the distance between any three consecutive rivets divided by two. A .325 pitch means that distance is 0.325 inches. This measurement is crucial for compatibility with your chainsaw’s drive sprocket and guide bar.
• Gauge: The gauge is the thickness of the drive links – the parts of the chain that fit into the groove of the guide bar. Common gauges for .325 chains are .050″ and .058″. Again, matching your chain gauge to your bar is vital.
• Drive Links: The number of drive links determines the length of the chain and must match the specifications for your guide bar.
• Full Chisel: As mentioned earlier, full chisel cutters have a square corner that provides an aggressive cutting action. This design excels in clean wood but is more susceptible to dulling in dirty or abrasive conditions.

Why Full Chisel?

You might be wondering why choose a full chisel chain over other options like semi-chisel or chipper chains. Here’s the breakdown:

• Speed: Full chisel chains are simply faster. The aggressive cutter design allows them to remove more wood with each pass.
• Efficiency: For experienced users, the increased cutting speed translates to increased efficiency. You can get more work done in less time.
• Ideal Applications: Full chisel chains shine in clean wood conditions, such as felling trees in managed forests or bucking freshly cut logs.

However, there are also drawbacks:

• Dulling: Full chisel chains dull faster than other types, especially in dirty wood or when contacting the ground.
• Sharpening: They require more precise sharpening to maintain their cutting edge. A slight error in sharpening can significantly impact performance.
• User Skill: They are less forgiving than other chain types. If you’re new to chainsaws, a semi-chisel chain might be a better starting point.

Maintaining Your .325 Full Chisel Chain

No matter which chain you choose, proper maintenance is crucial for maximizing its performance and lifespan. Here are some essential tips:

• Sharpening: Sharpen your chain regularly using a file guide and the correct file size. A dull chain is not only less efficient but also more dangerous. I personally prefer using a 5/32″ file for most .325 full chisel chains. Remember to maintain the correct angles for both the top plate and the side plate. A slightly off angle can drastically reduce cutting performance.
• Depth Gauge Adjustment: Check and adjust the depth gauges (also known as rakers) periodically. The depth gauges control how much the cutter bites into the wood. If they are too high, the chain will cut slowly. If they are too low, the chain may grab or kickback. I typically set my depth gauges to around .025″ below the top of the cutter.
• Lubrication: Ensure your chainsaw’s oiler is functioning properly and that you’re using a high-quality bar and chain oil. Proper lubrication reduces friction and wear, extending the life of your chain and bar. I’ve found that using a synthetic bar and chain oil is particularly beneficial in cold weather.
• Cleaning: Clean your chain regularly to remove sawdust, pitch, and other debris. A clean chain cuts more efficiently and is less prone to corrosion. I use a wire brush and a solvent to clean my chains.
• Tensioning: Maintain proper chain tension. A chain that is too loose can derail, while a chain that is too tight can overheat and wear prematurely. You should be able to pull the chain away from the bar slightly, but it shouldn’t sag excessively.
• Storage: Store your chains in a dry place to prevent rust. I like to soak my chains in oil before storing them for extended periods.

Wood Science: Understanding What You’re Cutting

Knowing a bit about wood science can significantly improve your chainsawing experience. Different wood species have different properties that affect how they cut and how they perform as firewood.

• Hardwood vs. Softwood: Hardwoods come from deciduous trees (trees that lose their leaves in the fall), while softwoods come from coniferous trees (trees that have needles and cones). Hardwoods are generally denser and harder than softwoods, making them more difficult to cut but also more durable and longer-burning as firewood.
• Moisture Content: The moisture content of wood significantly affects its cutting properties and its suitability for firewood. Green wood (freshly cut wood) has a high moisture content, making it heavier and more difficult to cut. Seasoned wood (wood that has been allowed to dry) has a lower moisture content, making it lighter, easier to cut, and more efficient to burn.
  • Data Point: Freshly cut oak can have a moisture content of over 80%, while seasoned oak typically has a moisture content of around 20%.
• Grain Direction: The direction of the wood grain also affects how it cuts. Cutting with the grain is generally easier than cutting against the grain.
• Density: Wood density is a measure of how much mass is packed into a given volume. Denser woods require more power to cut.
  • Data Point: Balsa wood, one of the least dense woods, has a density of around 8 lbs/cubic foot, while lignum vitae, one of the densest woods, has a density of around 83 lbs/cubic foot.

Firewood Seasoning Techniques and Safety Considerations

Properly seasoning firewood is essential for efficient burning and minimizing creosote buildup in your chimney. Here’s a breakdown of the process and some important safety considerations:

• Splitting: Split your firewood as soon as possible after felling the tree. Splitting exposes more surface area to the air, allowing the wood to dry faster. I prefer using a hydraulic splitter for larger rounds, but a good maul and wedge can also get the job done.
  • Data Point: Splitting firewood can reduce its drying time by as much as 50%.
• Stacking: Stack your firewood in a single row, off the ground, and in a sunny and windy location. This allows for maximum air circulation, which is crucial for drying. I like to use pallets to keep my firewood off the ground.
• Covering: Cover the top of your firewood pile to protect it from rain and snow, but leave the sides open to allow for air circulation.
• Seasoning Time: The amount of time it takes to season firewood depends on the wood species, the climate, and the stacking method. Generally, hardwoods require at least six months to a year to season properly, while softwoods may only require three to six months.
  • Data Point: Properly seasoned firewood should have a moisture content of 20% or less.
• Safety Considerations:
  • Wear appropriate safety gear: When splitting firewood, wear safety glasses, gloves, and steel-toed boots.
  • Use caution when operating a hydraulic splitter: Follow the manufacturer’s instructions carefully and never place your hands near the splitting wedge.
  • Be aware of your surroundings: When stacking firewood, be aware of uneven ground and potential tripping hazards.
  • Avoid stacking firewood too high: A tall stack of firewood can be unstable and could collapse.

Project Planning and Execution: A Case Study

Let’s walk through a hypothetical firewood project to illustrate how to apply these principles.

Scenario: You need to prepare 5 cords of firewood from a fallen oak tree on your property.

Step 1: Assessment:

• Tree Size: Estimate the diameter and length of the tree to determine the approximate volume of wood.
• Wood Condition: Assess the condition of the wood. Is it green or partially seasoned? Are there any signs of rot or insect infestation?
• Terrain: Evaluate the terrain around the tree. Is it flat and accessible, or is it steep and difficult to navigate?

Step 2: Tool Selection:

• Chainsaw: Choose a chainsaw with a .325 pitch chain that is appropriate for the size of the tree and the type of wood. I would recommend using a Stihl MS 261 with a Stihl Rapid Micro (RM) Pro .325″ chain for this project.
• Splitting Tools: Select splitting tools based on the size of the rounds. A hydraulic splitter is ideal for larger rounds, while a maul and wedge can be used for smaller rounds.
• Safety Gear: Gather all necessary safety gear, including safety glasses, gloves, steel-toed boots, and hearing protection.

Step 3: Felling and Bucking:

• Felling: If the tree is still standing, fell it safely using proper felling techniques.
• Bucking: Buck the tree into manageable lengths for splitting. I typically buck my firewood into 16-inch lengths.

Step 4: Splitting:

• Split the rounds: Split the rounds into pieces that are approximately 4-6 inches in diameter.

Step 5: Stacking:

• Stack the firewood: Stack the firewood in a single row, off the ground, and in a sunny and windy location.

Step 6: Seasoning:

• Allow the firewood to season: Allow the firewood to season for at least six months to a year before burning it.

Step 7: Monitoring:

• Monitor the moisture content: Use a moisture meter to check the moisture content of the firewood before burning it.

Data-Backed Content: Fuel Value Ratings

Not all firewood is created equal. Different wood species have different fuel value ratings, which indicate how much heat they produce when burned.

• Fuel Value: Fuel value is typically measured in British Thermal Units (BTUs) per cord. A BTU is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.
• Hardwood vs. Softwood: Hardwoods generally have higher fuel values than softwoods.
• Density: Denser woods typically have higher fuel values.

Here are some examples of fuel value ratings for common firewood species:

• Oak: 24-30 million BTUs per cord
• Maple: 20-25 million BTUs per cord
• Birch: 20 million BTUs per cord
• Ash: 24 million BTUs per cord
• Pine: 15-20 million BTUs per cord
• Fir: 15 million BTUs per cord

Choosing firewood with a high fuel value will result in more efficient heating and less frequent refueling.
