What to Look for in Best Stihl 20 Inch Chain

Understanding Pitch and Gauge

When selecting a replacement stihl 20 inch chain, the most critical step is matching the pitch and gauge exactly to your saw’s drive sprocket and guide bar groove. The pitch is the distance between drive links, while the gauge represents the thickness of the drive link tang. If you accidentally select a chain with a .063 gauge for a bar designed for .050, the chain will either bind or wobble, leading to dangerous kickback and premature bar wear. Always consult the stamped numbers on your existing bar or the owner’s manual before purchasing. For heavy-duty tasks like clearing fallen timber near irrigation lines or raised beds, ensuring a perfect fit prevents the chain from throwing, which protects both the operator and the delicate infrastructure of your garden layout.

Drive Link Count Accuracy

The number of drive links is the specific count of the teeth that ride inside the guide bar groove. Even if the bar length is 20 inches, a chain with 72 drive links will not fit a saw requiring 81 links. This measurement is non-negotiable because an incorrect count means the chain will either be too short to mount or too long to tension properly. When working in tight garden spaces—such as pruning fruit trees over irrigation zones or clearing brush near raised garden beds—a properly tensioned chain is vital. A loose chain poses a significant safety risk, while one that is too tight creates excessive friction, which can overheat the bar and degrade the chain's temper, shortening its lifespan significantly during routine maintenance.

Cutter Profile and Geometry

Stihl offers various cutter profiles, such as Rapid Micro (RM) and Rapid Super (RS), which dictate how the chain interacts with wood fibers. RM chains feature a semi-chisel design that stays sharp longer in dirty or abrasive conditions, making them ideal for clearing debris near soil contact areas where grit often dulls blades quickly. In contrast, RS chains use a full-chisel profile for aggressive, fast cutting in clean wood. For the average homeowner managing garden beds and small-scale landscaping, a semi-chisel chain is often the superior choice because it offers a balance of durability and cutting speed. It resists the dulling effects of occasional contact with bark or hidden garden stakes, ensuring you spend more time working and less time filing.

Material and Chrome Plating

The longevity of your stihl 20 inch chain is heavily influenced by the quality of the steel and the chrome plating on the cutter teeth. High-quality Stihl chains utilize proprietary steel alloys that resist stretching and heat-induced metal fatigue. The chrome coating acts as a protective barrier against oxidation and wear, maintaining the sharpness of the edge through multiple sharpening cycles. When maintaining a garden, you are often cutting wood that may have been exposed to moisture or soil, which accelerates corrosion. Investing in a chain with high-grade, thick chrome plating ensures that the cutting edge remains effective even when faced with the challenging conditions of outdoor garden maintenance, providing a better return on investment over the life of the chain.

Lubrication Efficiency Features

Effective oil distribution is the unsung hero of chainsaw longevity, and Stihl’s Oilomatic technology is designed to channel lubricant directly to the chain rivets and drive links. When selecting a chain, look for features that promote consistent oil flow, as this reduces the friction between the chain and the guide bar. In a garden setting, where you might be making frequent, short cuts to clear branches around irrigation pipes or raised beds, the saw experiences many start-stop cycles. Proper lubrication prevents the chain from 'blueing' due to heat buildup. A well-lubricated chain runs smoother, requires less engine power to drive, and significantly reduces the risk of the chain snapping during high-torque tasks, keeping your garden operations safe and efficient.

Anti-Vibration and Safety

Modern stihl 20 inch chain designs often incorporate anti-vibration links and low-kickback safety features. These elements are engineered to dampen the energy transferred from the chain to the saw body, which minimizes operator fatigue during long sessions of garden work. If you are managing large raised-bed layouts or clearing significant brush, vibrations can lead to hand-arm vibration syndrome over time. Furthermore, safety-focused chains include specialized depth gauges that prevent the cutter from biting too deeply into the wood, which is the primary cause of kickback. Choosing a chain with these integrated safety features provides an extra layer of protection, especially when working in awkward positions or confined spaces where you have less control over the saw's movement.

Sharpening Compatibility and Maintenance

Consider how easily the chain can be maintained using standard filing tools. A stihl 20 inch chain should be compatible with your existing round files or electric sharpeners. Some chains feature indicators on the cutter tops that show the optimal filing angle, which is incredibly helpful for maintaining consistent performance. If you are a DIY gardener, the ability to touch up your chain in the field is essential for maintaining productivity. A chain that is easy to sharpen ensures that you can keep your cutting edges razor-sharp, which reduces the strain on your chainsaw engine and provides cleaner cuts. Cleaner cuts result in faster healing for pruned trees and shrubs, supporting the overall health of your garden ecosystem.

Frequently Asked Questions

How often should I sharpen my 20-inch Stihl chain?

You should sharpen your chain as soon as you notice the saw pulling to one side or producing fine sawdust instead of wood chips. In a garden environment, if you have accidentally nicked a rock or hit soil while clearing debris near a raised bed, the chain will require immediate attention. Generally, a professional gardener might touch up the chain every two to three tanks of fuel to maintain peak efficiency. Keeping the cutters sharp prevents the engine from overworking and ensures that you are not applying excessive pressure, which can damage the guide bar and the chain drive links over time.

Can I use a non-Stihl chain on a Stihl chainsaw?

While it is technically possible to use aftermarket chains, it is highly recommended to stick with genuine Stihl parts. Stihl engineers their chains to match the specific geometry of their guide bars and sprockets, ensuring optimal oil flow and tensioning. Using a generic chain may lead to increased wear on your guide bar or, worse, a poor fit that increases the risk of the chain jumping the track. For the safety of your garden equipment and your own personal protection, the slight cost savings of generic chains rarely outweigh the reliability and performance benefits of the authentic Stihl product line.

How do I know if my chain is stretched too far?

A chain is stretched too far when you can no longer tension it properly using the adjustment screw on your chainsaw. If the tensioner is at its maximum limit and the chain still hangs loosely beneath the guide bar, the metal has physically elongated due to heat and wear. You should never attempt to shorten a stretched chain by removing a link, as this compromises the structural integrity of the chain. Once a chain reaches this state, it is time to replace it. Continuing to run a stretched chain is dangerous and will cause rapid, irreversible damage to the guide bar groove and the drive sprocket.

What is the difference between RS and RM chains?

The RS (Rapid Super) is a full-chisel chain designed for maximum cutting speed in clean, dry wood, making it perfect for felling larger trees. The RM (Rapid Micro) is a semi-chisel chain that is more forgiving and holds its edge longer, especially when cutting wood that might be dirty or near ground level. For garden tasks like pruning branches that might have dirt or grit on the bark, the RM chain is usually the better choice. It offers a more balanced performance profile, reducing the need for constant sharpening while still providing enough speed for typical residential landscape maintenance and clearing tasks.

How does soil contact affect my chain's lifespan?

Soil contact is the fastest way to destroy a chainsaw chain. Dirt and grit contain silica, which is incredibly abrasive and will dull a sharp chain in seconds. When you are working near raised beds or clearing brush that touches the ground, try to elevate the wood or use a 'bucking' technique that avoids hitting the earth. If you do hit the dirt, stop immediately and inspect the cutters. You will likely find the edges rounded over or chipped. Continuing to cut with a chain that has hit the ground will lead to excessive heat, which can permanently ruin the temper of the steel.

Does the chain pitch affect the cutting speed?

Yes, the pitch—the distance between drive links—directly influences how the saw handles the wood. A larger pitch like 3/8" is generally more aggressive and removes more wood per stroke, which is great for heavy-duty clearing. A smaller pitch like .325" is often smoother and easier to control, which is preferred for precision pruning in delicate garden areas. However, you cannot simply change the pitch of your chain; the pitch must match the drive sprocket on your saw. Always ensure that your replacement chain matches the original specifications of your chainsaw to avoid mechanical failure and ensure safe, efficient operation during your gardening projects.

Why is my chain smoking while I cut?

A smoking chain is a clear sign of excessive friction and heat, usually caused by a lack of lubrication or a dull chain. First, check that your chain oil reservoir is full and that the oil pump is functioning correctly by observing if a fine spray of oil is being thrown from the tip of the bar. If the oiling system is fine, the chain is likely dull, forcing you to push harder to make the cut. Stop immediately, let the saw cool down, and sharpen or replace the chain. Ignoring the smoke will lead to a ruined guide bar and potentially a seized engine.

How do I store my chainsaw chain to prevent rust?

If you are storing your chains for an extended period, clean them thoroughly to remove all wood chips and sap, then coat them lightly with fresh bar and chain oil. Store them in a cool, dry place, preferably in a sealed container or their original packaging. Moisture is the primary enemy of steel chains, especially in garden sheds where humidity levels can fluctuate. Keeping the chain oiled prevents oxidation on the rivets and cutters. When you are ready to use the chain again, check the tension after the first few cuts, as the chain may need a slight adjustment as it warms up.

Can I use a 20-inch chain on a 18-inch bar?

No, you absolutely cannot use a 20-inch chain on an 18-inch bar. The chain length must match the guide bar length exactly. A chain that is too long will be impossible to tension, leading to a loose chain that will inevitably derail from the bar. Derailment is extremely dangerous and can cause severe injury to the operator or bystanders. Always match the chain length to the specific bar length of your chainsaw. If you are unsure about the size, measure the bar from the front of the saw housing to the tip and check the drive link count stamped on the tail of the bar.

How does cold weather affect chain performance?

In cold weather, the metal of the chain becomes more brittle, and the chain oil becomes thicker, which can hinder proper lubrication. Before starting heavy work, let your saw warm up and run the chain at a low speed to ensure the oil is flowing freely to the bar. You may also need to adjust your chain tension more frequently in cold weather, as the metal components contract. Always use a high-quality, winter-grade bar oil if you are working in freezing temperatures to ensure that the chain remains well-lubricated and does not bind, which helps maintain safety and performance during winter garden cleanup.
