Why Sharpen Your Chainsaw Chain?
A sharp chainsaw chain is crucial for efficient and safe woodcutting. A dull chain makes your chainsaw work harder, leading to:
- Slower cutting: You’ll spend more time and effort trying to get through wood.
- Increased wear and tear: Your chainsaw’s engine and other components will be strained, leading to premature wear.
- Safety hazards: A dull chain can cause the saw to kickback, which is dangerous for the operator.
- Rougher cuts: The wood will have a jagged finish, often requiring more cleanup.
Regular sharpening ensures your chainsaw performs at its best and remains a safe tool to use.
The Dremel Advantage for Chainsaw Sharpening
While dedicated chainsaw files and sharpening kits are common, many users discover that a Dremel rotary tool chainsaw setup offers surprising convenience and precision, especially for touch-ups or when a specialized tool isn’t readily available. The versatility of a Dremel, combined with the right accessories, makes it a capable tool for keeping your chainsaw chain sharp.
Key Dremel Accessories for Chainsaw Sharpening
To successfully sharpen your chainsaw chain with a Dremel, you’ll need specific attachments. The most common and effective are:
- Dremel chainsaw file attachments: These are specifically shaped bits designed to mimic the profile of a traditional chainsaw file. They come in various diameters to match different chain pitches.
- Dremel grinding stone chainsaw bits: These are more aggressive and can be used for reshaping or significant dullness, though care must be taken not to remove too much metal.
- Dremel chainsaw sharpener attachment: These are often guide-like attachments that help maintain the correct angle for sharpening.
The best Dremel bit for chainsaw sharpening is typically a round file bit that matches the specific chain pitch. Consult your chainsaw manual or the chain manufacturer to determine the correct size.
What You’ll Need: A Dremel Chainsaw Sharpening Kit
While you can buy individual bits, a comprehensive Dremel sharpening kit chainsaw often includes a variety of bits and accessories that can be useful. At a minimum, ensure you have:
- Dremel Rotary Tool: A reliable Dremel tool is your base.
- Appropriate Dremel Bit for Chainsaw Chain: This is the most critical component. Look for round, burr-style bits designed for metal filing. Common sizes are 5/32-inch, 3/16-inch, and 7/32-inch, corresponding to chain pitches.
- Guide Attachment (Optional but Recommended): Many kits or standalone accessories offer a guide that helps maintain a consistent sharpening angle.
- Safety Gear: Always wear safety glasses and gloves.
- Work Surface: A stable surface for your Dremel.
- Chainsaw: The chain you intend to sharpen.

Step-by-Step Guide: How to Sharpen A Chainsaw With A Dremel
Now, let’s get down to the practical steps of sharpening chainsaw chain Dremel style. This process focuses on sharpening the cutter teeth of your chainsaw chain.
Step 1: Preparation and Safety First
Before you even plug in your Dremel, prioritize safety:
- Wear Safety Glasses: Metal filings can fly.
- Wear Gloves: Protect your hands from sharp edges and the heat generated.
- Secure the Chainsaw: Place the chainsaw on a stable, flat surface. Ensure it won’t move during the sharpening process. Some users clamp the chainsaw bar to a workbench.
- Identify Chain Pitch: This is vital for selecting the correct Dremel chainsaw file. Look for markings on your chainsaw chain or consult your chainsaw’s manual. The pitch is the distance between rivets, typically measured as 3/8-inch, .325-inch, or .404-inch.
Step 2: Selecting the Correct Dremel Bit
Choosing the right Dremel bit for chainsaw chain is paramount for an effective sharpening job.
- Match the Bit Diameter to the Chain Pitch: The round file bit should snugly fit the gullet (the curved part) of the cutting tooth.
- For a 1/4″ pitch chain, use a 1/8″ file.
- For a .325″ pitch chain, use a 5/32″ (4mm) file.
- For a 3/8″ pitch chain, use a 13/64″ (5.5mm) file.
- For a .404″ pitch chain, use a 3/16″ file.
- Check for Wear: Ensure the Dremel grinding stone chainsaw bit or file bit isn’t worn out. A worn bit won’t sharpen effectively.
Step 3: Setting Up Your Dremel
- Insert the Bit: Firmly secure the chosen Dremel bit into the collet of your Dremel tool.
- Choose the Speed: Start with a medium speed (around 10,000-15,000 RPM). Too fast can overheat the bit and the metal; too slow might not remove enough material. Experiment to find what works best.
- Using a Guide (Recommended): If you have a Dremel chainsaw sharpener attachment or a guide jig, attach it now. These guides are designed to help you maintain the correct angle.
Step 4: Sharpening the Cutter Teeth
This is where the actual how to use Dremel to sharpen chainsaw magic happens. You’ll be working on each cutter tooth individually.
- Locate the First Cutter: Start with a cutter tooth that has its “hook” (the cutting edge) facing away from you. Most chains have alternating left and right-facing cutters.
- Position the Dremel Bit: Place the round Dremel bit into the gullet of the cutter tooth. The bit should protrude slightly from the gullet’s opening.
- Maintain the Angle: This is critical. Most chainsaw chains require a sharpening angle of 25-35 degrees relative to the bar.
- Visual Guide: Imagine a line running along the top plate of the tooth. The angle is how much you tilt the Dremel bit upwards from that line.
- Using a Guide: If you have a guide, it will have markings or a fence to help you maintain this angle consistently.
- Without a Guide: You’ll need to develop a feel for this. A common method is to hold the Dremel at an angle that appears to align with the original sharpening marks on the tooth.
- The Filing Motion:
- Start at the Heel: Begin filing at the rear of the cutter tooth (the heel) and move forward towards the tip.
- Apply Light Pressure: Let the Dremel do the work. Excessive pressure can wear out the bit quickly and overheat the tooth.
- Sweep Motion: Use a smooth, sweeping motion.
- Number of Passes: Aim for 3-5 passes per tooth. The goal is to restore a sharp edge, not to reshape the tooth. Listen to the sound; it should be a consistent filing sound, not a scraping or chattering.
- Sharpening Every Tooth: After sharpening one tooth, move to the next cutter of the same orientation. Work your way around the entire chain, sharpening all teeth facing one direction.
- Switch Directions: Once you’ve sharpened all teeth on one side, rotate the chain (if possible, or just work from the other side of the bar) and repeat the process for all the teeth facing the opposite direction. Ensure you maintain the correct sharpening angle for these teeth as well.
Step 5: Checking and Refining
- Visual Inspection: Look at the teeth. They should have a bright, sharp edge. There shouldn’t be any dull, grey material left.
- Depth Gauges (Rakers): The depth gauges, located in front of each cutter, control how much wood the cutter removes. If they are too high, the chain won’t cut efficiently. If they are too low, the chain will cut too aggressively and can be dangerous.
- Checking: Use a depth gauge file, or a flat file guide, and a ruler or specialized depth gauge tool. The top of the depth gauge should be about 0.025 inches (0.6mm) below the cutting edge of the tooth.
- Filing: If a depth gauge is too high, use a flat file or a Dremel with a small flat grinding stone to gently lower it. Be careful not to overdo it. This is a less common requirement than sharpening the cutters themselves. The Dremel file chainsaw teeth is primarily for the cutting edge.
Step 6: Clean Up
- Remove Debris: Brush away any metal filings from the chain and bar.
- Lubricate: Apply a suitable bar and chain oil.
Tips for Success When Using a Dremel Chainsaw Sharpener Attachment
- Consistency is Key: The most important aspect of sharpening is maintaining a consistent angle on all teeth.
- Don’t Over-Sharpen: Removing too much metal will shorten the life of your chain. The goal is to restore the sharp edge, not to grind away the entire tooth.
- Practice on a Spare Chain: If you’re new to this, consider practicing on an old or spare chain to get a feel for the angles and pressure.
- Dremel Chainsaw File vs. Grinding Stone: For routine sharpening, the Dremel chainsaw file (burr bit) is preferred. A Dremel grinding stone chainsaw bit can be useful for more aggressive reshaping but requires more skill to avoid removing too much metal.
- Listen to the Dremel Rotary Tool: A smooth, consistent sound indicates you’re doing it right. Chattering or a strained sound means you might be applying too much pressure or the bit isn’t seated correctly.
