Why Choose a Dremel for Chainsaw Sharpening?

Several factors make the Dremel an attractive option for chainsaw sharpening:

Cost Savings: Professional sharpening can cost $15-$30 per chain. A Dremel and a set of sharpening stones can pay for themselves after just a few uses.
Convenience: Sharpen your chain whenever and wherever you need to, without waiting for a shop to open or dropping off your saw.
Precision: With practice, you can achieve a very sharp edge, maintaining the correct angle and depth for optimal cutting performance.
Portability: Dremels are compact and easy to transport, making them ideal for sharpening in the field.

Understanding Chainsaw Chain Anatomy

Before diving into the sharpening process, it’s crucial to understand the different parts of a chainsaw chain. This knowledge will ensure you sharpen each component correctly.

Cutters (Teeth): These are the primary cutting elements of the chain. Each cutter has a top plate and a side plate, which are sharpened to create a sharp edge.
Depth Gauges (Rakers): These control the amount of wood each cutter takes with each pass. They need to be filed down periodically to maintain optimal cutting performance.
Tie Straps: These connect the cutters and drive links, holding the chain together.
Drive Links: These fit into the guide bar groove and are driven by the chainsaw’s sprocket.

Essential Tools and Materials

To effectively sharpen your chainsaw with a Dremel, you’ll need the following tools and materials:

Dremel Rotary Tool: A variable-speed model is preferred for better control. I recommend the Dremel 4000 or 4300.
Chainsaw Sharpening Kit: This kit includes the correct size grinding stones for your chain pitch. Ensure the kit matches your chain type (e.g., .325″, 3/8″).
Depth Gauge Tool: A flat file and depth gauge tool are essential for maintaining the correct depth gauge height.
Gloves: Protect your hands from sharp edges and metal filings.
Eye Protection: Safety glasses or a face shield are crucial to prevent eye injuries from flying debris.
Vise or Chain Vise: A vise or chain vise will hold the chain steady during sharpening, improving accuracy and safety.
Marker: A permanent marker helps mark the starting tooth, ensuring you sharpen each cutter.
Cleaning Brush: A wire brush helps remove metal filings from the chain after sharpening.

Choosing the Right Sharpening Stone

Selecting the correct grinding stone is crucial for achieving a sharp and durable edge. The stone’s size and shape should match the cutter’s profile and chain pitch.

Stone Size: Use the Dremel’s recommended stone size for your chain pitch. A .325″ pitch chain typically requires a 5/32″ stone, while a 3/8″ pitch chain needs a 3/16″ or 7/32″ stone. Always refer to the chain manufacturer’s recommendations.
Stone Material: Aluminum oxide stones are suitable for general-purpose sharpening, while silicon carbide stones are more aggressive and better for harder chains or heavily damaged cutters.
Stone Shape: Conical or cylindrical stones are commonly used. Conical stones are ideal for sharpening the curved part of the cutter, while cylindrical stones are better for the top plate.

Setting Up Your Work Area

A well-organized workspace is essential for safe and efficient sharpening.

Lighting: Ensure adequate lighting to clearly see the cutting edges.
Ventilation: Sharpen in a well-ventilated area to avoid inhaling metal filings.
Stability: Securely mount your vise or chain vise to a stable surface. I use a small portable workbench that I can easily move around.
Organization: Keep your tools and materials within easy reach.

Step-by-Step Guide to Chainsaw Sharpening with a Dremel

Follow these steps to sharpen your chainsaw chain with a Dremel:

Step 1: Chain Preparation and Inspection

Clean the Chain: Use a wire brush to remove dirt, oil, and debris from the chain. This ensures the grinding stone doesn’t become clogged.
Inspect the Chain: Look for damaged or broken cutters. Replace the chain if there are significant issues. Minor damage can often be repaired with careful sharpening.
Secure the Chain: Place the chain in a vise or chain vise, ensuring it is held firmly in place.

Step 2: Setting the Dremel Speed and Angle

Speed: Start with a low to medium speed setting on your Dremel. Too high a speed can overheat the cutter and damage the steel. I typically start around 15,000 RPM and adjust as needed.
Angle: Maintain the correct sharpening angle as specified by the chain manufacturer. This is typically around 25-30 degrees for the top plate and 60 degrees for the side plate. Use the Dremel’s guide attachment if available, or practice maintaining the angle visually.

Step 3: Sharpening the Cutters

Mark the Starting Tooth: Use a permanent marker to mark the first cutter you sharpen. This helps you keep track of your progress.
Sharpen the Top Plate: Hold the Dremel at the correct angle and gently grind the top plate of the cutter. Use light, even strokes, following the original angle of the cutter. Avoid applying too much pressure, which can overheat the steel. I usually make 2-3 passes per cutter.
Sharpen the Side Plate: Rotate the Dremel and grind the side plate of the cutter. Again, use light, even strokes and maintain the correct angle. Pay attention to the shape of the cutter and try to maintain its original profile.
Repeat: Sharpen each cutter in the same manner, working your way around the chain. Ensure you sharpen each cutter to the same length and angle for consistent cutting performance.

Step 4: Filing the Depth Gauges

Check Depth Gauge Height: Use a depth gauge tool to check the height of the depth gauges (rakers). The depth gauges should be slightly lower than the cutters.
File the Depth Gauges: Place the depth gauge tool over the depth gauge and file down any protruding material with a flat file. File evenly to maintain the correct profile.
Round the Front Edge: Use the file to slightly round the front edge of the depth gauge. This helps prevent the chain from grabbing or kicking back.

Step 5: Final Inspection and Cleaning

Inspect the Chain: Check each cutter to ensure it is sharp and evenly sharpened. Look for any remaining damage or imperfections.
Clean the Chain: Use a wire brush to remove any remaining metal filings from the chain.
Lubricate the Chain: Apply chain oil to the chain to lubricate the cutters and prevent rust.

Advanced Techniques for Dremel Chainsaw Sharpening

Once you’ve mastered the basic techniques, you can explore advanced methods to further improve your sharpening skills.

Using a Chainsaw Sharpening Attachment

Dremel offers a chainsaw sharpening attachment that can help you maintain a consistent angle and depth. This attachment is particularly useful for beginners or those who struggle to maintain a steady hand.

Attachment Setup: Attach the sharpening attachment to your Dremel and adjust the guide to match your chain pitch.
Sharpening Process: Place the attachment against the cutter and grind the top plate and side plate, following the guide. The attachment helps maintain the correct angle and depth, resulting in a more consistent sharpening job.

Freehand Sharpening Techniques

Experienced users may prefer freehand sharpening, which allows for more control and customization.

Visual Guides: Use visual cues to maintain the correct angle and depth. Pay attention to the shape of the cutter and try to replicate it with each pass.
Practice: Freehand sharpening requires practice. Start with a scrap chain and experiment with different angles and pressures until you achieve the desired results.

Addressing Common Sharpening Issues

Uneven Sharpening: Ensure you sharpen each cutter to the same length and angle. Use a marker to track your progress and visually inspect each cutter after sharpening.
Overheating: Avoid applying too much pressure or using too high a speed. Overheating can damage the steel and reduce the cutter’s lifespan.
Incorrect Angle: Maintain the correct sharpening angle as specified by the chain manufacturer. Use a Dremel guide attachment or practice freehand sharpening until you can consistently maintain the correct angle.
Dull Edge: If the chain is still dull after sharpening, check the grinding stone for wear. Replace the stone if it is worn or clogged. Also, ensure you are applying enough pressure and using the correct sharpening angle.

Understanding Chain Pitch and Gauge

The chain pitch and gauge are critical measurements that determine the chain’s compatibility with your chainsaw and the correct size of the sharpening stone.

Chain Pitch: The pitch is the distance between any three consecutive rivets on the chain, divided by two. Common chain pitches include .325″, 3/8″, and .404″. The pitch determines the size of the cutters and the overall aggressiveness of the chain.
Chain Gauge: The gauge is the thickness of the drive links that fit into the guide bar groove. Common chain gauges include .043″, .050″, .058″, and .063″. The gauge must match the width of the guide bar groove for proper chain operation.

Maintaining Your Chainsaw Chain

Proper chain maintenance is essential for extending the life of your chain and ensuring optimal cutting performance.

Regular Sharpening: Sharpen your chain regularly, ideally after each use or when you notice a decrease in cutting performance. A sharp chain cuts faster, smoother, and safer.
Chain Lubrication: Keep your chain well-lubricated with chain oil. Proper lubrication reduces friction and wear, extending the life of the chain and guide bar.
Chain Tension: Maintain the correct chain tension. A properly tensioned chain should be snug against the guide bar but still able to be pulled around the bar by hand.
Chain Cleaning: Clean your chain regularly to remove dirt, oil, and debris. Use a wire brush or solvent to clean the chain, and then lubricate it with chain oil.
Chain Storage: Store your chain in a dry place to prevent rust. Consider using a chain case or bag to protect the chain from damage.
