  6. Move to the next tooth and repeat – Continue sequentially until all teeth are sharpened.
  7. Test the sharpness – Carefully check that each tooth has been sharpened to a sharp edge.

Using this process, you can efficiently sharpen each tooth to the ideal 30 degree angle. Take your time and double check your work. A Dremel makes it easy to maintain a deadly sharp chain.

Chainsaw Maintenance Tips

In addition to regular sharpening, proper chainsaw maintenance helps ensure safe operation and less downtime. Here are key maintenance tasks to perform daily, weekly, and monthly.

Daily Maintenance

Daily upkeep goes a long way towards keeping your chainsaw in tip-top shape:

  • Test the trigger – Ensure it engages and disengages properly for safe starting and stopping.
  • Clean the chainsaw – Remove any sawdust, sap, and debris after each use.
  • Check chain tension – Tighten if loose to the proper tension specified by manufacturer.
  • Inspect the air intake vent – Clear any obstructions and clean filter as needed.
  • Check nuts, bolts, and screws – Tighten anything loose to prevent vibration damage.

Weekly Maintenance

Perform these tasks weekly for optimal performance and safety:

  • Check anti-vibration wear and tear – Inspect mounts and rubber dampeners. Replace deteriorated vibration isolators.
  • Inspect the spark plug – Clean or replace as needed for strong ignition.
  • Clean the carburetor – Use compressed air to blow out any debris.
  • Check the fuel filter – Replace if clogged to maintain proper fuel flow.

Monthly Maintenance

For maximum chainsaw life, make sure to do monthly:

  • Check the chain brake band – Replace worn brake bands immediately for safety.
  • Inspect the drive sprocket – Replace if worn, chipped, or damaged.
  • Clean the bar groove – Remove built-up sawdust to avoid guide bar damage.
  • Inspect the lubrication hole – Clear any obstructions to maintain oil flow to the bar and chain.

Staying on top of maintenance activities helps ensure your chainsaw performs optimally when needed.

Chainsaw Sharpening Alternatives

While a Dremel is an excellent option, there are other methods available for sharpening your chainsaw chain:

Hand File

The traditional manual approach uses a round file and filing guide. Pros are low cost and portability. Cons are slower and easy to make filing errors.

Portable Power Sharpener

These electric sharpeners are compact and allow sharpening in the field. Drawbacks are less precision and difficulty detecting sharpening errors.

Benchtop Sharpener

Stationary shop sharpeners mount the guide bar and use grinding wheels. Very precise but less portable. Good for heavy duty use.

Each system has pros and cons. For most users, a Dremel provides the best balance of affordability, precision, speed, and ease of use. But evaluate your usage and needs.


Regularly sharpening the chain on your chainsaw using a Dremel rotary tool is simple and effective. The precision and control of a Dremel allows properly sharpening each tooth to maximize cutting effectiveness. Make sure to take safety precautions and properly maintain your chainsaw. Keeping the chain razor sharp will boost performance and safety. Let me know if you have any other chainsaw or Dremel questions!

Frequently Asked Questions

How often should I sharpen my chainsaw?

You should sharpen your chainsaw chain after every 2-3 typical uses, or immediately if you notice any loss of cutting speed or performance. This helps maximize cutting efficiency and prevents premature chain/bar wear.

What is the correct angle for sharpening a chainsaw?

Most chainsaw cutter teeth should be sharpened to a 30 degree angle. Use a sharpening guide attachment on your Dremel to ensure this proper angle on each tooth.

How do I know if my chainsaw chain is dull?

Signs your chain is dull include needing extra force to cut, increased sawdust vs. chips, or the saw veering/binding during cuts. Visually inspect teeth for rounded edges vs sharp points.

Can I use a regular file to sharpen my chainsaw?

Yes, round hand files can be used to sharpen chainsaw chains. However, it is slower and you must maintain the filing angle manually. Files are a good portable option but a Dremel is much easier and precise.

How do I maintain the proper tension on my chainsaw chain?

Consult your owner’s manual for the proper tension. There should be just enough sag in the chain midway between the guide bar ends to pull on it and have the tie straps enter the groove.

What type of oil should I use for my chainsaw?

Use good quality bar and chain oil designed specifically for chainsaws. It contains additives to help the oil stick during cutting and not sling off the spinning chain too quickly. Never use motor oil.

How can I prevent my chainsaw from overheating?

Keep the ventilation intake free of debris, maintain proper chain tension, sharpen chain regularly, lubricate bar adequately, and avoid prolonged use at maximum revs. Allow cooling between cuts.
