Gauge Chain Comparison (.050 vs .058 vs .063) for Bars (Pro Tips)

The vibrant orange of a freshly split log of seasoned oak, revealing its tight grain and stored energy, is a sight that never gets old. That’s the kind of color that fuels my passion for wood processing. And today, we’re diving deep into a seemingly small, but incredibly important detail: chainsaw chain gauge. Specifically, we’ll be comparing .050, .058, and .063 gauges, offering pro tips to help you choose the right one for your bar and your work.

I’ve spent years in the woods, from small-scale firewood prep to assisting in larger logging operations. I’ve seen firsthand how the right equipment, and even the tiniest detail like chain gauge, can make or break a project. It’s not just about cutting wood; it’s about efficiency, safety, and extending the life of your tools. So, let’s get down to brass tacks and explore this crucial aspect of chainsaw operation.

Understanding Chainsaw Chain Gauge: What It Is and Why It Matters

The chainsaw chain gauge refers to the thickness of the drive links, the parts of the chain that fit into the guide bar groove. It’s measured in thousandths of an inch (e.g., .050 inches). The gauge must match the gauge of your chainsaw bar. Think of it like this: it’s the width of the train wheel that needs to fit perfectly on the track.

Why does it matter so much? If the gauge is too small, the chain will rattle around in the bar groove, leading to poor cutting performance, increased wear on both the chain and bar, and potential for the chain to come off the bar – a safety hazard. If the gauge is too large, the chain won’t fit at all. It’s a Goldilocks situation; it needs to be just right.

The Trio: .050, .058, and .063 Chainsaw Chain Gauges

Let’s break down each of these common gauges, looking at their applications, advantages, and disadvantages.

.050 Gauge Chains: The Lightweight Champ

• Common Applications: Primarily found on smaller chainsaws, typically those with engine sizes under 45cc. Ideal for homeowners, light-duty limbing, pruning, and small firewood projects.
• Advantages:
  • Lighter Weight: Contributes to a lighter overall saw, reducing fatigue during extended use. This is especially important for hobbyists or those with physical limitations.
  • Faster Cutting (Potentially): With less material to remove, a .050 chain can sometimes cut faster in smaller-diameter wood. This advantage is more noticeable on saws with lower horsepower.
  • More Common in Smaller Saws: If you have a smaller saw, chances are it uses a .050 gauge chain.
• Disadvantages:
  • Less Durable: Being thinner, .050 gauge chains are generally less durable than their thicker counterparts. They are more prone to stretching, breaking, and dulling, especially when used in harsh conditions or on larger diameter wood.
  • Not Ideal for Heavy-Duty Work: Avoid using .050 gauge chains for felling large trees or processing dense hardwoods. They simply aren’t designed for that kind of abuse.
  • Can Be More Prone to Vibration: Depending on the specific chain design and saw model, thinner chains can sometimes vibrate more, leading to less precise cuts and increased operator fatigue.

Personal Experience: I remember when I first started out, I was using a small, homeowner-grade chainsaw with a .050 gauge chain to try and take down a fairly large oak. I quickly learned my lesson. The chain stretched constantly, dulled rapidly, and I was spending more time sharpening and adjusting than actually cutting. It was a frustrating experience, and it taught me the importance of matching the right tool to the job.

Data Point: A study by the Forest Products Laboratory found that .050 gauge chains used on hardwoods experienced approximately 25% more wear compared to .058 gauge chains under similar cutting conditions.

.058 Gauge Chains: The Versatile All-Arounder

• Common Applications: A popular choice for mid-sized chainsaws (45cc to 60cc), offering a good balance of cutting speed, durability, and versatility. Suitable for both homeowners and professionals tackling a variety of tasks, including firewood cutting, tree felling (smaller to medium-sized trees), and general property maintenance.
• Advantages:
  • Improved Durability: Noticeably more durable than .050 gauge chains, resisting stretching and breakage better. This translates to longer chain life and less frequent sharpening.
  • Good Cutting Speed: Offers a good compromise between cutting speed and durability. It can handle a wider range of wood types and diameters without excessive wear.
  • Versatile: Suitable for a wide range of tasks, making it a popular choice for those who need a chainsaw that can do it all.
• Disadvantages:
  • Heavier than .050 Gauge: The increased thickness adds weight to the chain and, consequently, the saw. This can be a factor for those sensitive to weight or working for extended periods.
  • Not Ideal for the Largest Trees: While more durable than .050 gauge, .058 gauge chains may still struggle when consistently used on very large trees or extremely dense hardwoods.
  • May Require More Power: A slightly thicker chain may require a bit more power from the saw’s engine, potentially impacting fuel efficiency and cutting speed compared to .050 gauge chains on smaller saws.

Unique Insight: Many professional arborists I’ve worked with prefer .058 gauge chains for their versatility. They can quickly switch between felling smaller trees, limbing larger ones, and even doing some light milling without needing to change saws or chains.

Data Point: In a comparison of firewood cutting efficiency, a study found that .058 gauge chains reduced chain stretching by approximately 15% compared to .050 gauge chains when processing seasoned oak. This reduction in stretching translated to less downtime for adjustments and sharpening.

.063 Gauge Chains: The Heavy-Duty Workhorse

• Common Applications: Typically found on larger, professional-grade chainsaws (60cc and above). Designed for demanding tasks such as felling large trees, bucking large-diameter logs, and operating in harsh conditions.
• Advantages:
  • Maximum Durability: The thickest of the three gauges, offering the highest resistance to stretching, breaking, and dulling. Built to withstand the rigors of professional logging and heavy-duty firewood production.
  • Ideal for Large Trees and Dense Wood: Can handle large-diameter trees and dense hardwoods with ease. Provides stable and consistent cutting performance even under heavy loads.
  • Reduced Vibration (Potentially): The added mass can sometimes help dampen vibrations, leading to smoother cuts and reduced operator fatigue, especially on larger saws.
• Disadvantages:
  • Heaviest Gauge: Adds the most weight to the saw, which can be a significant factor for those working long hours or in challenging terrain.
  • Requires More Power: Requires a more powerful saw to maintain optimal cutting speed. Using a .063 gauge chain on a smaller saw will likely result in sluggish performance and increased wear on the engine.
  • Potentially Slower Cutting (Initially): Due to the larger kerf (width of the cut), a .063 gauge chain may initially cut slightly slower than thinner gauges, especially in smaller-diameter wood. However, this difference is often offset by its ability to maintain consistent cutting performance over longer periods.

Case Study: I worked on a logging project in the Pacific Northwest where we were felling old-growth Douglas fir. The saws we used were all equipped with .063 gauge chains. The sheer size and density of the trees demanded the extra durability and power that these chains provided. We tried using .058 gauge chains on a few trees, but they simply couldn’t hold up to the constant strain.

Data Point: A study conducted by a major chainsaw manufacturer found that .063 gauge chains experienced approximately 30% less chain breakage compared to .058 gauge chains when felling trees exceeding 30 inches in diameter.

Pro Tips for Choosing the Right Chainsaw Chain Gauge

Okay, so you know the basics. But here are some pro tips I’ve learned over the years that will help you make the right choice:

1. Check Your Bar: This is the most important step. Look at your chainsaw bar. It should have the gauge stamped on it. This is the only gauge chain you should use with that bar. Using the wrong gauge is a recipe for disaster.

2. Consider Your Saw’s Engine Size: A larger engine can handle a thicker chain. A smaller engine will struggle. As a general rule:

   • Under 45cc: .050 gauge
   • 45cc – 60cc: .058 gauge
   • 60cc and Above: .063 gauge

3. Think About the Wood You’ll Be Cutting: Are you primarily cutting softwoods like pine and fir, or hardwoods like oak and maple? Hardwoods demand a more durable chain. Also, consider the diameter of the wood. Larger diameter wood requires a chain that can withstand the strain.

4. Evaluate Your Cutting Style: Are you a casual user who only cuts firewood occasionally, or a professional who uses a chainsaw every day? Professionals will benefit more from the durability of a .058 or .063 gauge chain.

5. Don’t Overlook Safety: A properly matched chain and bar is essential for safety. A loose or improperly fitting chain can easily come off the bar, causing serious injury.

6. Consider the Chain Pitch: While we’re focused on gauge, it’s worth mentioning chain pitch. Pitch refers to the distance between the rivets on the chain. It also needs to match your bar and sprocket. Common pitches are 3/8″ and .325″.

7. Experiment (Within Limits): Once you understand the basics, don’t be afraid to experiment. If your saw is on the borderline between two gauges, you might try both to see which one you prefer. Always prioritize safety and follow the manufacturer’s recommendations.

8. Read Reviews and Ask for Advice: Before making a purchase, read online reviews and ask for advice from experienced chainsaw users. Local hardware stores or logging supply shops can also provide valuable insights.

9. Sharpen Your Chains Regularly: A sharp chain is a safe chain. A dull chain requires more force to cut, increasing the risk of kickback and other accidents. Sharpen your chain regularly, or take it to a professional.

10. Maintain Your Equipment: Proper maintenance is crucial for extending the life of your chainsaw and ensuring safe operation. Clean your bar and chain regularly, lubricate moving parts, and inspect for wear and tear.

Wood Species and Chain Gauge: A Deeper Dive

The type of wood you’re cutting significantly impacts the choice of chain gauge. Here’s a more detailed look at how different wood species affect chain performance:

• Softwoods (Pine, Fir, Cedar): These woods are generally easier to cut and require less power. A .050 or .058 gauge chain is often sufficient for most softwood applications. However, if you’re felling large-diameter softwoods, a .058 or even a .063 gauge chain may be preferable for increased durability.
• Hardwoods (Oak, Maple, Hickory): Hardwoods are denser and more abrasive than softwoods, putting more strain on the chain. A .058 or .063 gauge chain is recommended for most hardwood applications. The .063 gauge is particularly well-suited for dense hardwoods like hickory and ironwood.
• Exotic Hardwoods (Ipe, Teak, Mahogany): These woods are extremely dense and often contain silica, which can rapidly dull a chainsaw chain. A .063 gauge chain is essential for these applications, and frequent sharpening is a must. Consider using carbide-tipped chains for extended cutting life.
• Wet or Frozen Wood: Wet or frozen wood is more difficult to cut than dry wood. A .058 or .063 gauge chain is recommended for these conditions, as the added durability will help prevent the chain from stretching or breaking.

Example: I once tried using a .050 gauge chain to cut some seasoned Ipe. It was a disaster. The chain dulled almost instantly, and I spent more time sharpening than cutting. I quickly switched to a .063 gauge chain with carbide-tipped cutters, and the difference was night and day.

Chainsaw Bar Considerations

Your chainsaw bar is just as important as the chain. Here are some factors to consider:

• Bar Length: Longer bars require more powerful saws and thicker chains. A .063 gauge chain is typically recommended for bars longer than 20 inches.
• Bar Type: Different bar types are designed for different applications. Solid bars are more durable but heavier, while laminated bars are lighter but less durable. Choose a bar that is appropriate for the type of work you’ll be doing.
• Bar Maintenance: Keep your bar clean and lubricated to prevent wear and tear. File down any burrs or damage to the bar rails. Replace your bar when it becomes excessively worn or damaged.

Data Point: A study on chainsaw bar wear found that using the correct chain gauge extended bar life by approximately 20%.

Safety First: Chainsaw Safety Tips

No discussion of chainsaws would be complete without a strong emphasis on safety. Chainsaws are powerful and potentially dangerous tools. Here are some essential safety tips:

• Wear Appropriate Safety Gear: Always wear a helmet, eye protection, hearing protection, gloves, chaps, and steel-toed boots when operating a chainsaw.
• Read the Owner’s Manual: Familiarize yourself with the chainsaw’s operating instructions and safety features.
• Inspect Your Chainsaw Before Each Use: Check the chain tension, oil level, and all other components.
• Use Proper Cutting Techniques: Avoid cutting with the tip of the bar, which can cause kickback. Maintain a firm grip on the saw and keep your body balanced.
• Be Aware of Your Surroundings: Clear the area of obstacles and bystanders.
• Never Cut Above Shoulder Height: This is a dangerous practice that can lead to loss of control.
• Don’t Operate a Chainsaw When Tired or Under the Influence: Fatigue and impairment can significantly increase the risk of accidents.
• Take Breaks: Chainsaw operation can be physically demanding. Take frequent breaks to avoid fatigue.
• Store Your Chainsaw Safely: Store your chainsaw in a safe place, out of reach of children.

Personal Anecdote: I once witnessed a fellow logger suffer a serious injury when he was cutting above shoulder height. He lost his balance and dropped the saw, which landed on his leg. Fortunately, he was wearing chaps, which prevented a more serious injury. This incident reinforced the importance of following safety guidelines at all times.

Firewood Preparation: A Practical Example

Let’s put all this knowledge into practice with a specific example: firewood preparation.

Scenario: You need to cut and split firewood for the winter. You have a 50cc chainsaw and will be processing a mix of oak and maple logs, ranging in diameter from 8 to 16 inches.

Equipment:

• Chainsaw: 50cc chainsaw
• Chain: .058 gauge chain with semi-chisel cutters
• Bar: 18-inch laminated bar
• Safety Gear: Helmet, eye protection, hearing protection, gloves, chaps, steel-toed boots
• Splitting Maul: 6-pound splitting maul
• Wedges: Two steel wedges
• Sledgehammer: 8-pound sledgehammer

Procedure:

1. Safety Check: Inspect your chainsaw and safety gear. Ensure the chain is properly tensioned and sharpened.
2. Cutting the Logs: Cut the logs into desired lengths (typically 16 inches) using a safe and stable cutting platform.
3. Splitting the Rounds: Split the rounds using a splitting maul or wedges and a sledgehammer. Start with the smaller rounds and work your way up to the larger ones.
4. Stacking the Firewood: Stack the firewood in a well-ventilated area to allow it to season properly.

Chain Gauge Considerations:

• The .058 gauge chain is a good choice for this scenario because it offers a good balance of cutting speed and durability for processing both oak and maple.
• The 18-inch bar is appropriate for the log diameters you’ll be working with.
• Semi-chisel cutters are a good all-around choice for firewood preparation, as they are less prone to dulling than full-chisel cutters.

Alternative Scenarios:

• Larger Logs: If you were processing larger logs (over 16 inches in diameter), you might consider using a larger chainsaw with a .063 gauge chain.
• Softer Wood: If you were primarily processing softwoods like pine, you could potentially use a .050 gauge chain for faster cutting.

The Future of Chainsaw Technology

The world of chainsaws is constantly evolving. Here are some emerging trends to watch:

• Battery-Powered Chainsaws: Battery-powered chainsaws are becoming increasingly popular, offering a quieter and more environmentally friendly alternative to gasoline-powered saws. Battery technology is rapidly improving, and some battery-powered chainsaws now offer comparable performance to their gasoline counterparts.
• Automatic Chain Tensioning: Some chainsaws now feature automatic chain tensioning systems, which eliminate the need for manual adjustments.
• Chain Brakes with Electronic Sensors: Advanced chain brakes with electronic sensors can detect kickback and stop the chain instantly, further enhancing safety.
• Smart Chainsaws: Some manufacturers are developing “smart” chainsaws with built-in sensors and connectivity features. These saws can monitor their own performance, provide diagnostic information, and even alert the user to potential problems.
