CHAINSAW SHARPENING With a DREMEL: Lazy or Genius?
How to Sharpen a Chainsaw with a Dremel: A Step-by-Step Guide
A sharp chainsaw is crucial for efficient and safe cutting, but sharpening it by hand can be time-consuming and tedious. That’s where a Dremel tool comes in! Using a Dremel to sharpen your chainsaw is a fast and effective way to restore its cutting power. Here’s how you can get it done like a pro.
Why Use a Dremel for Sharpening?
A Dremel rotary tool offers precision and speed when sharpening chainsaw teeth. With the right attachments, it simplifies the process and ensures consistent results. It’s particularly useful for:
Restoring a dull chain quickly.
Maintaining the correct angle with minimal effort.
Reducing wear on the chain compared to traditional hand files.
What You’ll Need
To sharpen your chainsaw with a Dremel, gather these tools and materials:
Dremel Rotary Tool: Ensure it’s fully charged or plugged in.
Chainsaw Sharpening Attachment Kit: These kits often include guide attachments and sharpening bits.
Safety Gear: Goggles, gloves, and ear protection.
Flathead Screwdriver: For chain tension adjustments.
Cloth or Brush: To clean the chain before sharpening.
Step-by-Step Sharpening Instructions
Step 1: Prepare the Chainsaw
Turn off the chainsaw and ensure it’s cool to the touch.
Remove debris and sawdust from the chain using a brush or cloth.
Adjust the chain tension so it’s snug but still moves freely.
Step 2: Set Up the Dremel Tool
Attach the appropriate sharpening bit to your Dremel. Most chains require a bit diameter of 5/32”, 3/16”, or 7/32” depending on the chain’s pitch.
Secure the sharpening guide attachment to the Dremel, setting the correct angle (usually 25° or 30°, as specified by your chain’s manufacturer).
Step 3: Sharpen the Teeth
Clamp the chainsaw bar in a vice to keep it stable.
Position the Dremel bit inside the first tooth’s cutting edge, aligning it with the guide attachment.
Turn on the Dremel and apply light pressure as you run the bit across the tooth’s edge. It should take 2-3 passes to sharpen each tooth.
Move to every second tooth along the chain, as alternating teeth face opposite directions.
Step 4: Switch Sides
Once all teeth on one side are sharpened, reposition the chainsaw or adjust your angle to sharpen the remaining teeth.
Repeat the same process, ensuring consistency.
Step 5: Sharpen the Depth Gauges (Rakers)
Use a depth gauge tool to check the height of the rakers.
If necessary, file them down slightly with a flat file to ensure they don’t impede cutting performance.
Step 6: Final Check and Cleanup
Inspect the chain for sharpness and consistency.
Wipe down the chain and bar to remove any metal filings.
Recheck the chain tension and make adjustments if needed.
Tips for Success
Maintain a Consistent Angle: Proper alignment ensures even sharpening and optimal performance.
Avoid Over-Sharpening: Removing too much material can shorten the chain’s lifespan.
Work in a Well-Lit Area: Better visibility helps ensure accuracy.
Replace Worn Bits: A dull Dremel bit can damage the chain.
When to Replace Your Chain
Even with regular sharpening, chains wear out over time. Replace your chainsaw chain if:
The teeth are too worn down to sharpen effectively.
Cracks or damage are visible on the chain.
Performance remains poor despite sharpening.
Final Thoughts
Sharpening your chainsaw with a Dremel is a game-changer for anyone looking to save time and effort. With practice, you’ll keep your chainsaw in peak condition, ready to tackle any cutting job efficiently. Invest in a quality Dremel tool and sharpening kit, and you’ll wonder how you ever managed without them!
