Should My Chainsaw Chain Be 30 or 35 Degrees? (Explained)

When selecting a chainsaw chain, one of the most important decisions is the cutter angle – typically 30 or 35 degrees. But which should you choose? This comprehensive guide examines the pros and cons of each to help you decide.

What is a Cutter Angle?

The cutter angle refers to the angle between the top plate of the cutter and the side plate. Most chainsaw chains have a cutter angle of either 30 or 35 degrees. This angle determines:

• How aggressively the chain cuts
• The size of the wood chips
• Sharpening requirements
• Cutting smoothness

Understanding the implications of this angle will ensure you select the best chain for your needs.

30 Degree Chainsaw Chains

Pros

• More Aggressive Cutting: The narrow 30 degree angle allows the cutter to penetrate wood faster. This makes the chain better suited for professional use where fast and efficient cutting is required.
• Smaller Wood Chips: 30 degree chains produce very small, almost powder-like chips. The smaller chips clear out of the cut path easier.
• Easier to Sharpen: Only having to sharpen one angle instead of two makes maintenance simpler.

Cons

• More Vibration: More steel in contact with the wood causes increased vibration and operator fatigue. Not ideal for occasional users.
• Require More Power: The aggressive cutting takes more power from the chainsaw. Underpowered saws may bog down with a 30 degree chain.
• Decreased Cutting Smoothness: Chatter and roughness may occur as the narrow cutters take uneven bites of wood.

The extreme aggression of 30 degree chains makes them best suited for professional full-time use where speed is essential. The increased vibration and power demand also makes them unsuitable for most hobbyist or casual users.

35 Degree Chainsaw Chains

Pros

• Smoother Cutting: The slightly rounded 35 degree edge helps the cutter glide through wood effortlessly. This greatly reduces vibration and chatter for maximum smoothness.
• Less Fatiguing: With less steel touching the wood at once, these chains are significantly less jarring and uncomfortable for the operator. The smooth cut makes them joy to use.
• Lower Power Requirement: The rounded cutters require less power to penetrate wood. This prevents bogging down and overworking most chainsaw engines.
• Longer Lasting: The decreased aggression means less stress on each cutter. This leads to a longer lifespan before sharpening is required.

Cons

• Slower Cutting Speed: These chains trade off some cutting aggression for smoothness. Professionals requiring maximum productivity may want more speed.
• Larger Wood Chips: The 35 degree edge creates longer curly chips that take more effort to discharge from the cut area.
• Two Sharpening Angles: Maintaining both the top and side plate angles requires more skill during sharpening.

While 35 degree chains don’t cut as quickly, their balanced smoothness and lower power needs make them ideal for most casual users and homeowners. The ability to run longer between sharpenings also makes maintenance easier.

Tips for Deciding Between 30 or 35 Degrees

When choosing a cutter angle, first consider how you will use your chainsaw. Here are some tips:

For Occasional Use – A 35 degree chain is likely the best choice. The smooth cut makes projects enjoyable rather than a chore. Lower vibration and power needs also prevents early fatigue for those not accustomed to using chainsaws regularly.

For Professional Use – Professionals who use chainsaws daily will likely prefer a 30 degree chain. The aggressive cutting action increases productivity so more jobs can be completed each day. Operators who are experienced with managing chainsaw forces can also better handle increased vibrations.

For Underpowered Saws – Chainsaws with lower horsepower or electric models run the risk of bogging down with an aggressive chain. The lower power demand of 35 degrees makes them a great match for these saws.

For Felling Large Timber – Felling big trees requires long cuts through thick wood. A 30 degree chain stays sharp longer when making long cuts and won’t slow down deep inside the trunk.

For Cutting Hardwood – Hardwoods like oak and maple quickly dull chain cutters. Using a 30 degree chain allows cutting more wood before sharpening becomes necessary.

Recommendations By Chainsaw Size

The optimal chain angle also depends on the size of your chainsaw:

Electric & Battery Chainsaws Under 14” – Small electric saws work best with 35 degree chains in standard .043” gauge. The smooth cut helps compensate for the low power, while narrower gauge prevents undue bogging.

Gas Chainsaws 14”-18” – Homeowner grade mid-size saws can utilize either 30 or 35 degree chains effectively. Gauge choice depends on wood type rather than cutter angle. Operators should choose based on use case.

Large Displacement Professional Saws 20”+ – The most powerful professional grade saws 20” and above almost universally utilize 30 degree chains. At .050”+ gauge, the aggressive chains take full advantage of the high power and torque.

When in doubt, check your operator’s manual – most will indicate optimum chain types including recommended gauge and angles. Using a chain outside specifications can impact safe operation.

Additional Factors When Selecting Chains

While cutter angle represents a critical choice, there are other considerations when selecting chains:

Gauge – Thickness of drive links, which impacts durability and chip flow. Follow manufacturer specifications.

Pitch – Spacing between each cutter, which must match bar groove width. Typically .325” or 3/8”.

Chain Type – Such as skip vs full comp, and low profile vs full chisel.

Length – Chains must match bar length to ensure adequate tension.

Drive Link Count – The number of drive links must match the chainsaw model.

Consulting an expert can ensure optimal chain selection for your saw, cutting needs, and experience level.

FAQ

Still have questions about chainsaw chain angles? Here are answers to some frequently asked questions:

What are the main differences between 30 and 35 degree chains?

30 degree chains cut faster but cause more vibration, while 35 degree chains provide a smoother cut with less operator fatigue. 30 degree chains stay sharp longer when cutting thick or dirty wood.

Can I use a 30 degree chain on a smaller electric chainsaw?

It’s not advisable. The aggressive chain can overwork a compact electric saw leading to bogging or premature wear. Stick to 35 degrees.

Should I choose gauge or angle first when selecting a chain?

Always begin by confirming the gauge specified by your saw’s manual. Once the correct gauge is chosen, then decide on angle based on your usage.

Do some chainsaws require a specific degree chain?

Most chainsaws work with either 30 or 35 degree chains. Some specialty saws designed for carving or other niche tasks may dictate a specific chain angle. When in doubt, check your manual.

Can I sharpen a 30 degree chain to 35 easily?

No. Converting chain angles requires special tools and expertise. It’s best to select the correct angle initially rather than attempting to alter it after purchase. Buy 2 chains in different angles if required.

Conclusion

Whether you should choose a 30 vs 35 degree chain depends greatly on your usage patterns and chainsaw model. Keeping your individual needs and capabilities in mind, rather than just going with the most aggressive option, ensures optimal performance and enjoyment of your saw.

Consult experts, manuals, and the tips in this guide to make the right decision. With the proper chain for your needs, you’ll experience smooth, efficient, and safe cutting for years to come.
