Dremel Tool for Chainsaw Sharpening (Pro Tips for Woodcutters)

Let’s talk about upgrading your chainsaw sharpening game with a Dremel tool. I’ve spent years felling trees and processing wood, and I know how crucial a sharp chain is. A dull chain means wasted effort, increased risk of kickback, and a whole lot of frustration. While traditional files have their place, a Dremel offers a faster, more precise way to keep your chainsaw cutting like new. This guide is based on my own hands-on experience and will walk you through everything you need to know, from choosing the right Dremel and accessories to mastering the sharpening technique.

Dremel Tool for Chainsaw Sharpening: Pro Tips for Woodcutters

Why Choose a Dremel for Chainsaw Sharpening?

For years, I stubbornly stuck to hand filing. “If it ain’t broke, don’t fix it,” I thought. But after a particularly grueling week of cutting dense oak for firewood, I decided to give a Dremel a try. The difference was remarkable.

• Speed and Efficiency: A Dremel significantly reduces sharpening time compared to hand filing. What used to take me 20-30 minutes per chain now takes 10-15 minutes.
• Precision: The small grinding stones allow for precise sharpening, ensuring consistent angles and depth.
• Accessibility: Dremels can reach tight spots and angles that are difficult to access with a file.
• Versatility: A Dremel isn’t just for chainsaws. You can use it for other tasks around the workshop, like grinding, cutting, and polishing.

While a Dremel won’t replace hand filing entirely (I still carry a file for quick touch-ups in the field), it’s become an indispensable tool in my sharpening arsenal.

Selecting the Right Dremel Tool

Not all Dremels are created equal. Here’s what to look for when choosing a Dremel for chainsaw sharpening:

• Corded vs. Cordless: Corded Dremels offer consistent power, which is crucial for maintaining consistent grinding speed. Cordless Dremels provide more freedom of movement, but you’ll need to keep the battery charged. I prefer a corded model for sharpening in my workshop and a cordless model for occasional touch-ups in the field.
• Variable Speed: A variable speed Dremel is essential. You’ll need to adjust the speed depending on the type of chain and the grinding stone you’re using.
• Motor Power: Look for a Dremel with a motor that can handle extended use without overheating. A motor with at least 1.0 amp is recommended.
• Ergonomics: Choose a Dremel that feels comfortable in your hand and allows for precise control. A lightweight model with a good grip is ideal.

My Recommendation: The Dremel 4000 is a solid choice for chainsaw sharpening. It’s corded, has variable speed, and offers plenty of power.

Essential Accessories for Chainsaw Sharpening

The Dremel itself is only half the equation. You’ll also need the right accessories:

• Sharpening Stones: These are the heart of the system. Choose stones specifically designed for chainsaw sharpening. They come in various sizes and shapes to match different chain pitches.

  • Diameter: A smaller diameter stone (e.g., 5/32 inch) is for smaller chains, while a larger diameter stone (e.g., 7/32 inch) is for larger chains.
  • Shape: Most sharpening stones are cylindrical or conical. Cylindrical stones are good for general sharpening, while conical stones are useful for reaching tight corners.
  • Material: Aluminum oxide stones are a good general-purpose choice.
  • Sharpening Attachment/Guide: This is crucial for maintaining consistent sharpening angles and depth. A good guide will help you achieve professional-quality results, even if you’re a beginner. Look for guides that are adjustable to fit different chain pitches and sharpening angles. The Dremel A679-02 Sharpening Attachment is a popular choice.
  • Depth Gauge Tool: This tool helps you ensure that the depth gauges (rakers) are properly set after sharpening the cutters.
  • Safety Glasses: Protect your eyes from flying debris.
  • Gloves: Protect your hands from cuts and abrasions.
  • Dust Mask: Protect your lungs from dust and metal particles.

Understanding Chainsaw Chain Anatomy

Before you start sharpening, it’s important to understand the different parts of a chainsaw chain:

• Cutters (Teeth): These are the parts that actually cut the wood. Each cutter has a top plate and a side plate.
• Depth Gauges (Rakers): These control the depth of the cut. If the depth gauges are too high, the chain won’t cut effectively. If they’re too low, the chain will grab and kick back.
• Tie Straps: These connect the cutters and depth gauges.
• Drive Links: These fit into the groove of the guide bar and pull the chain around.

Understanding these components is key to achieving a properly sharpened chain.

Setting Up Your Sharpening Station

A well-organized sharpening station will make the process much easier and more efficient. Here’s what I recommend:

1. Choose a well-lit and ventilated area. Good lighting is essential for seeing what you’re doing. Ventilation will help remove dust and fumes.
2. Secure your chainsaw. Use a vise or a chainsaw stand to hold the saw firmly in place. This will allow you to focus on sharpening without having to worry about the saw moving around.
3. Gather your tools and accessories. Make sure you have everything you need within easy reach: Dremel, sharpening stones, sharpening attachment, depth gauge tool, safety glasses, gloves, and dust mask.
4. Clean your chain. Use a brush to remove any dirt, sawdust, or oil from the chain. A clean chain will make it easier to see the cutting edges and will prevent the sharpening stones from becoming clogged.

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

Now, let’s get down to the nitty-gritty. Here’s a step-by-step guide to sharpening your chainsaw with a Dremel:

1. Prepare the Chain:
   • Clean the chain thoroughly with a wire brush to remove any dirt, oil, or debris. This will help prevent the grinding stones from clogging and ensure a clean, accurate cut.
   • Inspect the chain for any damaged or broken teeth. If you find any, replace the chain or have it professionally repaired.
2. Set Up the Dremel and Sharpening Attachment:
   • Insert the correct size sharpening stone into the Dremel. Refer to your chainsaw’s manual or the chain manufacturer’s specifications to determine the correct stone size. For example, a 3/8″ pitch chain typically requires a 5/32″ stone.
   • Attach the sharpening attachment to the Dremel.
   • Adjust the sharpening attachment to the correct angle and depth. The angle is typically between 25 and 35 degrees, depending on the chain. The depth should be set so that the stone removes a small amount of material with each pass.
3. Sharpen the Cutters:
   • Start with the shortest cutter as a reference point. This will ensure that all the cutters are sharpened to the same length.
   • Hold the Dremel firmly and guide the sharpening stone along the top plate of the cutter, following the original angle. Use light, even pressure.
   • Make several passes, removing a small amount of material with each pass. Avoid applying too much pressure, as this can overheat the stone and damage the cutter.
   • Repeat the process for the side plate of the cutter.
   • Sharpen each cutter on one side of the chain, then flip the saw and sharpen the cutters on the other side. This will help maintain balance and prevent uneven wear.
4. Check the Depth Gauges (Rakers):
   • After sharpening the cutters, check the height of the depth gauges. The depth gauges should be slightly lower than the cutters.
   • Use a depth gauge tool to measure the height of the depth gauges. The tool will have markings indicating the correct height for different chain pitches.
   • If the depth gauges are too high, use a flat file to lower them. File them evenly, maintaining a rounded profile.
5. Test the Chain:
   • After sharpening the chain, test it on a piece of wood. The chain should cut smoothly and aggressively, producing large, even chips.
   • If the chain is not cutting properly, re-sharpen the cutters or adjust the depth gauges as needed.

Detailed Sharpening Steps with Metrics

Let’s break down the sharpening process with specific measurements and guidelines:

• Angle: Aim for a top plate angle of 30 degrees. Use the markings on the sharpening attachment as a guide. This angle provides a good balance between cutting speed and durability.
• Depth: Set the sharpening attachment depth so that the stone removes approximately 0.005 inches (0.13 mm) of material with each pass. This is a very small amount, so use a light touch.
• Passes: Make 2-3 passes per cutter. More passes may be needed if the chain is very dull or damaged.
• Speed: Use a medium speed setting on the Dremel (around 20,000 RPM). Higher speeds can overheat the stone and damage the cutter.
• Pressure: Apply light, even pressure. Let the stone do the work. Avoid pressing too hard, as this can cause the stone to break or wear unevenly.
• Sharpening Time: Aim to spend approximately 30-60 seconds per cutter. This will give you enough time to remove the necessary material without overheating the stone.
• Depth Gauge Setting: For a 3/8″ pitch chain, set the depth gauges to approximately 0.025 inches (0.64 mm) below the cutters. Use a depth gauge tool to ensure accurate settings.

Example Scenario: I was recently sharpening a 20-inch chainsaw chain with a 3/8″ pitch. I used a 5/32″ sharpening stone, set the sharpening attachment to 30 degrees, and made three passes per cutter, removing approximately 0.005 inches of material with each pass. I then checked the depth gauges and filed them down to 0.025 inches below the cutters. The entire process took about 15 minutes, and the chain cut like new.

Advanced Techniques and Tips

Once you’ve mastered the basics, here are some advanced techniques and tips to further improve your chainsaw sharpening skills:

• Consistent Pressure: Maintaining consistent pressure is key to achieving even sharpening. Practice applying the same amount of pressure with each pass.
• Cooling the Stone: If the sharpening stone starts to overheat, dip it in water to cool it down. This will prevent it from becoming damaged and will help prolong its life.
• Sharpening in the Field: A cordless Dremel can be a lifesaver in the field. Carry a spare battery and a small selection of sharpening stones.
• Adjusting for Different Wood Types: Softer woods require a more aggressive chain with lower depth gauges. Harder woods require a less aggressive chain with higher depth gauges. Adjust your sharpening technique accordingly.
• Maintaining Your Sharpening Tools: Keep your sharpening stones clean and in good condition. Use a dressing stone to remove any buildup of metal particles. Store your Dremel and sharpening attachment in a safe and dry place.

Common Mistakes to Avoid

Even experienced woodcutters can make mistakes when sharpening their chainsaws. Here are some common mistakes to avoid:

• Using the Wrong Size Sharpening Stone: Using a stone that is too large or too small can damage the cutters and prevent the chain from cutting properly.
• Sharpening at the Wrong Angle: Sharpening at the wrong angle can weaken the cutters and make them more prone to breakage.
• Applying Too Much Pressure: Applying too much pressure can overheat the stone and damage the cutter.
• Ignoring the Depth Gauges: Neglecting the depth gauges can cause the chain to grab and kick back.
• Not Cleaning the Chain: Sharpening a dirty chain can clog the sharpening stones and prevent them from cutting effectively.

Troubleshooting Sharpening Problems

If you’re having trouble sharpening your chainsaw, here are some common problems and solutions:

• Chain is not cutting smoothly: Re-sharpen the cutters and check the depth gauges.
• Chain is grabbing and kicking back: Check the depth gauges and make sure they are properly set.
• Chain is cutting unevenly: Make sure you are sharpening each cutter to the same length and angle.
• Sharpening stone is wearing out quickly: Use light, even pressure and avoid overheating the stone.
• Dremel is overheating: Use a lower speed setting and allow the Dremel to cool down periodically.

• Case Study 2: The Arborist: An arborist was finding it difficult to sharpen his chainsaws in the field. He purchased a cordless Dremel and a sharpening attachment, which allowed him to quickly and easily touch up his chainsaws between jobs. This improved his efficiency and reduced the risk of accidents.
• Real-World Example 1: I was recently cutting down a large oak tree that had been damaged in a storm. My chainsaw chain became dull after only a few hours of use. I used my Dremel to quickly sharpen the chain, and I was able to finish the job without having to switch to a new chain.
• Real-World Example 2: A friend of mine was using a dull chainsaw to cut firewood. He was struggling to make progress and was becoming increasingly frustrated. I showed him how to sharpen his chain with a Dremel, and he was amazed at the difference. He was able to cut through the wood much more easily and efficiently.

Alternative Sharpening Methods

While a Dremel is a great tool for chainsaw sharpening, it’s not the only option. Here are some alternative sharpening methods:

• Hand Filing: This is the traditional method of chainsaw sharpening. It involves using a round file to sharpen the cutters and a flat file to adjust the depth gauges. Hand filing is a slower and more labor-intensive process than using a Dremel, but it can be a good option for quick touch-ups in the field.
• Electric Chainsaw Sharpener: These sharpeners use a grinding wheel to sharpen the cutters. They are faster and more precise than hand filing, but they can be more expensive than a Dremel.
• Professional Sharpening: You can also take your chainsaw to a professional sharpening service. This is the most expensive option, but it can be a good choice if you’re not comfortable sharpening your own chainsaw or if your chain is severely damaged.
