EXL Chain vs LGX: Which Oregon Chainsaw Chain Performs Best? (Pro Guide)

EXL Chain vs LGX: Which Oregon Chainsaw Chain Performs Best? (Pro Guide)

As a seasoned logger and firewood enthusiast, I’ve spent countless hours wrestling with chainsaws, felling trees, and splitting wood. Over the years, I’ve learned that the heart of any good chainsaw is its chain. A dull or poorly chosen chain can turn a manageable task into a frustrating ordeal. Two of their most popular chains, the EXL and the LGX, often leave users wondering: which one is truly the best?

The truth is, there’s no single “best” chain. The ideal choice depends on your specific needs, the type of wood you’re cutting, and even your chainsaw model. Think of it like choosing the right tires for your truck – you wouldn’t put mud tires on a vehicle primarily used for highway driving, would you? Similarly, selecting the right chainsaw chain is about matching the tool to the task.

Customizability is key. Chainsaw chains are not one-size-fits-all. Understanding the nuances of each chain type allows you to optimize your cutting performance, extend the life of your equipment, and most importantly, stay safe while working. In this guide, I’ll break down the key differences between the Oregon EXL and LGX chains, drawing on my personal experiences and technical knowledge to help you make an informed decision. I’ll also share some hard-earned wisdom I have learned over the years, including tips on chain maintenance, sharpening, and safety practices.

Understanding Chainsaw Chain Terminology

Before diving into the specifics of the EXL and LGX, let’s clarify some essential chainsaw chain terminology. This will help you understand the technical specifications I’ll be discussing later.

• Pitch: The distance between any three consecutive rivets divided by two. This determines the chain’s compatibility with your chainsaw’s drive sprocket and bar. Common pitches include .325″, 3/8″, and .404″.
• Gauge: The thickness of the drive links, which fit into the groove of the chainsaw bar. Common gauges include .050″, .058″, and .063″.
• Drive Links: The number of drive links determines the length of the chain. This number must match the length specified for your chainsaw bar.
• Cutters: The teeth on the chain that do the actual cutting. There are different types of cutters, each designed for specific cutting conditions. These include:
  • Full Chisel: Aggressive cutting, best for clean wood. Requires more skill to sharpen.
  • Semi-Chisel: More forgiving than full chisel, suitable for slightly dirty wood. Easier to sharpen.
  • Micro-Chisel: Rounded cutters, very durable and forgiving, ideal for dirty or frozen wood.
• Rakers (Depth Gauges): Small projections in front of each cutter that control the depth of the cut. Properly filed rakers are crucial for efficient cutting.
• Anti-Vibration Designs: Features designed to reduce vibration transmitted to the operator, improving comfort and reducing fatigue.
• LubriTec™: Oregon’s proprietary lubrication system designed to keep the chain and bar oiled for reduced friction and longer life.

Oregon EXL Chain: The Workhorse

The Oregon EXL chain (also known as the 72EXL) is a popular choice for professionals and serious homeowners alike. It’s known for its durability, reliability, and ability to handle a variety of cutting conditions.

Key Features of the EXL Chain:

• Type: Semi-Chisel
• Intended Use: General purpose cutting, felling, limbing, and bucking.
• Wood Types: Suitable for both hardwoods and softwoods.
• Gauge Options: Available in .050″, .058″, and .063″.

• Blued Cutters: Provides improved corrosion resistance.

EXL Chain Performance and Handling

From my experience, the EXL chain excels in situations where you need a balance of cutting speed and durability. It’s not the fastest chain on the market, but it’s incredibly reliable, even when cutting dirty or knotty wood. I’ve used EXL chains extensively for firewood processing, and they’ve consistently held up well against the grit and grime that inevitably comes with the job.

One thing I appreciate about the EXL is its ease of sharpening. The semi-chisel cutters are more forgiving than full chisel cutters, making them easier to maintain, especially for those who are new to chainsaw maintenance. This is a significant advantage, as a properly sharpened chain is essential for both safety and efficiency.

EXL Chain: Technical Specifications

• Steel Alloy: Oregon uses a proprietary steel alloy for its chains, designed for high strength and wear resistance. While the exact composition is proprietary, it’s known to include elements like chromium and nickel for enhanced hardness and corrosion resistance.
• Hardness: The cutters are typically hardened to a Rockwell C hardness of 58-60 HRC. This provides a good balance of wear resistance and toughness.
• Tensile Strength: The chain’s tensile strength is typically around 9,500 lbs. This is a critical factor in preventing chain breakage, especially when cutting large diameter logs.
• Lubrication Requirements: Oregon recommends using a high-quality bar and chain oil with a viscosity of SAE 30 or higher. The LubriTec™ system helps distribute the oil evenly along the chain and bar, reducing friction and wear.

EXL Chain: Advantages

• Cost-Effective: Generally more affordable than the LGX chain.

EXL Chain: Disadvantages

• Cutting Speed: Not as fast as the LGX chain in clean wood.
• Aggressiveness: Less aggressive than full chisel chains, requiring more pressure when cutting hardwoods.
• Susceptibility to Dullness: Can dull more quickly than full chisel chains when cutting extremely dirty wood.

Oregon LGX Chain: The Speed Demon

The Oregon LGX chain (also known as the 73LGX) is designed for speed and efficiency. It features full chisel cutters that provide aggressive cutting performance, making it a favorite among professional loggers and those who prioritize speed above all else.

The full chisel cutters slice through clean wood with minimal effort, allowing you to fell trees and buck logs in record time. I remember one particular job where I was tasked with clearing a large stand of pine trees. Using an LGX chain on my Stihl MS 462, I was able to cut through those trees like butter. The speed and efficiency were truly impressive.

However, the LGX chain’s aggressive cutting performance comes with a trade-off. Full chisel cutters are more susceptible to damage from dirt and debris, and they require more frequent sharpening. They are also less forgiving than semi-chisel cutters, meaning that even a slightly dull LGX chain can become difficult to control.

LGX Chain: Technical Specifications

• Steel Alloy: Similar to the EXL chain, the LGX chain uses a proprietary steel alloy designed for high strength and wear resistance.
• Hardness: The cutters are typically hardened to a Rockwell C hardness of 59-61 HRC. This slightly higher hardness provides increased wear resistance, but also makes the cutters more brittle.
• Tensile Strength: The chain’s tensile strength is comparable to the EXL chain, typically around 9,500 lbs.
• Lubrication Requirements: Similar to the EXL chain, Oregon recommends using a high-quality bar and chain oil with a viscosity of SAE 30 or higher. The LubriTec™ system is particularly important for the LGX chain, as the aggressive cutters generate more heat and friction.

LGX Chain: Advantages

• Cutting Speed: Significantly faster than the EXL chain in clean wood.
• Aggressiveness: Full chisel cutters provide exceptional cutting power.
• Efficiency: Allows you to cut more wood in less time.
• Vibration Reduction: Vibe-Ban™ chassis reduces vibration, improving operator comfort.
• Professional Grade: Preferred by many professional loggers.

LGX Chain: Disadvantages

• Durability: Less durable than the EXL chain, especially when cutting dirty wood.
• Sharpening: Requires more frequent and precise sharpening.
• Cost: Generally more expensive than the EXL chain.
• Forgiveness: Less forgiving than semi-chisel chains, requiring more skill and experience to use safely.

Maintaining Your Chainsaw Chain: A Pro’s Tips

No matter which chain you choose, proper maintenance is essential for maximizing its performance and lifespan. Here are some tips I’ve learned over the years:

• Sharpen Regularly: A sharp chain is a safe chain. Sharpen your chain every time you refuel your chainsaw, or more often if you’re cutting dirty wood.
  • Filing Angle: Maintain the correct filing angle for your chain. This is typically around 30 degrees for semi-chisel cutters and 25 degrees for full chisel cutters. Refer to your chainsaw’s manual for specific recommendations.
  • Raker Depth: Check and adjust the raker depth after every few sharpenings. Too much raker depth can cause the chain to grab and kick back, while too little raker depth will reduce cutting efficiency.
• Lubricate Properly: Use a high-quality bar and chain oil. Check the oil level frequently and refill as needed.
  • Oil Flow: Ensure that the oiler is functioning properly and that the oil is reaching the chain. A dry chain will quickly overheat and dull.
  • Winter Lubrication: In cold weather, use a winter-grade bar and chain oil that is designed to flow at lower temperatures.
• Clean Regularly: Remove sawdust and debris from the chain and bar after each use. This will help prevent wear and tear.
  • Bar Groove Cleaning: Clean the bar groove regularly to ensure proper chain lubrication.
  • Sprocket Cleaning: Inspect and clean the drive sprocket regularly to ensure proper chain engagement.
• Store Properly: Store your chainsaw with the chain and bar protected from the elements. This will help prevent rust and corrosion.
  • Chain Storage: Consider storing your chains in a container of oil to keep them lubricated and prevent rust.
• Chain Tension: Maintain the correct chain tension. A chain that is too loose can derail, while a chain that is too tight can overheat and wear prematurely.
  • Tension Check: Check the chain tension before each use and adjust as needed.
  • New Chains: New chains will stretch more quickly than used chains, so check the tension more frequently during the first few hours of use.

Safety First: Chainsaw Safety Practices

Chainsaws are powerful tools that can be dangerous if not used properly. Here are some essential safety practices to follow:

• Wear Appropriate Safety Gear: Always wear a helmet, eye protection, hearing protection, gloves, chaps, and steel-toed boots when operating a chainsaw.
  • Chaps: Chainsaw chaps are designed to stop the chain in the event of a kickback.
  • Gloves: Wear gloves that provide a good grip and protect your hands from cuts and abrasions.
• Maintain a Safe Working Area: Clear the area of obstacles and ensure that you have a clear escape route.
  • Bystanders: Keep bystanders at a safe distance.
  • Footing: Ensure that you have solid footing before starting the chainsaw.
• Use the Correct Cutting Techniques: Learn and practice the correct cutting techniques to minimize the risk of kickback.
  • Kickback Zone: Be aware of the kickback zone at the tip of the bar.
  • Boring Cuts: Avoid boring cuts whenever possible, as they are particularly prone to kickback.
• Inspect Your Chainsaw Regularly: Check the chain, bar, and other components for damage before each use.
  • Chain Damage: Replace the chain if it is damaged or worn.
  • Bar Condition: Check the bar for wear and damage.
• Never Operate a Chainsaw When You Are Tired or Impaired: Fatigue and impairment can significantly increase the risk of accidents.
• Follow the Manufacturer’s Instructions: Always follow the manufacturer’s instructions for operating and maintaining your chainsaw.

A Personal Anecdote: I recall a time when I was rushing to finish a firewood project before dark. I was tired and not paying as much attention as I should have been. As a result, I experienced a kickback that nearly resulted in a serious injury. Fortunately, I was wearing all the necessary safety gear, including chaps, which stopped the chain before it could reach my leg. That experience taught me a valuable lesson about the importance of safety and the need to always be alert when operating a chainsaw.

Troubleshooting Common Chainsaw Chain Problems

Even with proper maintenance, you may encounter problems with your chainsaw chain from time to time. Here are some common issues and how to troubleshoot them:

• Chain Dullness: This is the most common problem. Sharpen the chain regularly to maintain its cutting performance.
• Chain Breakage: This can be caused by excessive wear, improper tension, or hitting a foreign object. Replace the chain if it breaks.
• Chain Derailment: This can be caused by a loose chain, a worn sprocket, or a damaged bar. Adjust the chain tension and inspect the sprocket and bar for damage.
• Chain Overheating: This can be caused by insufficient lubrication, a dull chain, or excessive pressure. Check the oil level, sharpen the chain, and reduce the amount of pressure you’re applying.
• Chain Kickback: This can be caused by improper cutting techniques, a dull chain, or hitting a knot or other obstruction. Use the correct cutting techniques, sharpen the chain, and be aware of the kickback zone.
• Uneven Cutting: This can be caused by uneven sharpening or a damaged bar. Sharpen the chain evenly and inspect the bar for damage.

Advanced Techniques: Optimizing Chain Performance

For those looking to take their chainsaw skills to the next level, here are some advanced techniques for optimizing chain performance:

• Custom Chain Modifications: Some users modify their chains to improve cutting speed or durability. This can involve altering the cutter angles, adjusting the raker depth, or even welding on additional cutters. However, these modifications should only be performed by experienced professionals, as they can affect the safety and performance of the chain.
• Specialty Chains: There are a variety of specialty chains available for specific applications, such as ripping chains for milling lumber or carbide-tipped chains for cutting extremely hard or abrasive materials.
• Chain Selection for Specific Wood Types: Different wood types require different chain characteristics. For example, softwoods like pine and fir are best cut with full chisel chains, while hardwoods like oak and maple may require semi-chisel or even micro-chisel chains.
• Understanding Wood Moisture Content: The moisture content of the wood can significantly affect cutting performance. Green wood (freshly cut wood) is typically easier to cut than dry wood, but it can also be more prone to binding and kickback. Kiln-dried wood, on the other hand, is more difficult to cut but is less likely to bind.

Data Point: According to the US Forest Service, the average moisture content of green wood is around 80-100%, while the moisture content of air-dried wood is typically around 12-15%. Firewood should have a moisture content of 20% or less for optimal burning.

The Future of Chainsaw Chain Technology

Chainsaw chain technology is constantly evolving. Manufacturers are continually developing new materials, designs, and features to improve cutting performance, durability, and safety. Some of the trends I see shaping the future of chainsaw chains include:

• Improved Steel Alloys: New steel alloys are being developed that offer increased strength, wear resistance, and corrosion resistance.
• Advanced Cutter Designs: New cutter designs are being developed that provide faster cutting speeds and improved chip ejection.
• Smart Chains: Some manufacturers are exploring the use of sensors and electronics to monitor chain performance and provide feedback to the operator.
• Bio-Based Lubricants: Environmentally friendly bio-based lubricants are becoming increasingly popular as a sustainable alternative to traditional petroleum-based oils.
