Let’s dive in!
The Age-Old Chainsaw Sharpening Dilemma: Dremel vs. File – A Pro Woodworker’s Take
As a seasoned woodworker and someone who’s spent countless hours prepping firewood and felling trees, I’ve wrestled with the same question many of you have: What’s the best way to sharpen a chainsaw? Is it the modern convenience of a Dremel chainsaw sharpener kit, or the traditional, time-tested method of filing? It’s a question that’s more than just about sharpness; it’s about efficiency, cost, and ultimately, the longevity of your chainsaw. I’m going to share my insights, learned through years of experience (and a few mistakes along the way), to help you make the right choice.
Understanding the Stakes: Why Chainsaw Sharpness Matters
Before we get into the nitty-gritty of sharpening techniques, let’s understand why a sharp chainsaw is crucial. It’s not just about making the job easier; it’s about safety, efficiency, and the health of your equipment.
- Safety First: A dull chain requires more force to cut, increasing the risk of kickback. Kickback, according to the Consumer Product Safety Commission (CPSC), is a leading cause of chainsaw injuries. A sharp chain bites into the wood smoothly, reducing the likelihood of this dangerous event.
- Efficiency: A sharp chainsaw cuts faster and requires less effort. This translates to less fuel consumption, reduced wear and tear on the saw, and less fatigue for you. I remember one particular job where I was felling a large oak with a dull chain. I was constantly fighting the saw, and it took me nearly twice as long to finish the job compared to when I used a properly sharpened chain.
- Chain and Saw Longevity: A dull chain puts extra strain on the saw’s engine and bar. This can lead to premature wear and tear, resulting in costly repairs or replacements. A sharp chain allows the saw to work as intended, extending its lifespan.

My Personal Journey: From Dremel Disaster to Filing Finesse
My first foray into chainsaw sharpening was with a Dremel kit. I was excited by the promise of quick and easy sharpening. However, my initial attempts were disastrous. I overheated the chain, rounded off the cutters, and ended up with a chain that was duller than before I started. I learned the hard way that speed isn’t everything; precision and control are paramount.
Discouraged, I turned to a seasoned logger in my community, a man named Old Man Hemlock (a nickname earned from his skill in felling massive hemlocks). He patiently taught me the art of filing. He emphasized the importance of maintaining the correct angles, using a sharp file, and taking my time. It was a slow and deliberate process, but the results were undeniable. My chainsaw cut smoother, faster, and with less effort.
Deep Dive: The Art and Science of Chainsaw Sharpening
Whether you choose a Dremel or a file, understanding the principles of chainsaw sharpening is essential.
Understanding Chain Anatomy
A chainsaw chain consists of several key components:
- Cutters: These are the teeth that do the cutting. Each cutter has a top plate and a side plate, which form the cutting edges.
- Depth Gauges (Rakers): These control the depth of the cut. They sit slightly lower than the cutters.
- Tie Straps: These connect the cutters and depth gauges, forming the chain.
- Drive Links: These fit into the bar groove and are driven by the sprocket.
Key Angles and Measurements
Maintaining the correct angles and measurements is crucial for optimal cutting performance.
- Top Plate Angle: This is the angle of the top plate relative to the chain. It typically ranges from 55 to 60 degrees.
- Side Plate Angle: This is the angle of the side plate relative to the chain. It typically ranges from 60 to 75 degrees.
- Depth Gauge Setting: This is the height difference between the depth gauge and the cutter. It typically ranges from 0.025 to 0.030 inches.
- Hook: The hook angle is the angle of the tooth in relation to the direction of travel.
These angles can vary slightly depending on the type of chain and the type of wood you’re cutting. Consult your chainsaw’s manual for specific recommendations.
Step-by-Step Guide to Filing a Chainsaw
Here’s a detailed guide to filing a chainsaw, based on my years of experience and the wisdom passed down from Old Man Hemlock:
- Secure the Chainsaw: Clamp the chainsaw in a vise or use a stump vise to hold it securely.
- Choose the Right File: Use a round file that matches the size of the cutter. Your chainsaw manual will specify the correct file size.
- Use a Filing Guide: A filing guide helps maintain the correct angles and depths. There are various types of filing guides available, from simple clip-on guides to more sophisticated models.
- Position the File: Place the file in the cutter, aligning it with the filing guide. Ensure the file is at the correct top plate and side plate angles.
- File the Cutter: Use smooth, even strokes to file the cutter. File from the inside of the cutter outwards. Avoid applying too much pressure, as this can damage the file or the chain.
- Count Your Strokes: Count the number of strokes you use on each cutter. This will help ensure that all cutters are sharpened equally.
- Sharpen All Cutters: Sharpen all the cutters on one side of the chain, then flip the chainsaw and sharpen the cutters on the other side.
- Check the Depth Gauges: After sharpening the cutters, check the depth gauges. Use a depth gauge tool to measure the height difference between the depth gauge and the cutter. If the depth gauge is too high, use a flat file to lower it.
- Test the Chain: After sharpening, test the chain by making a few cuts. The chain should cut smoothly and efficiently.
Step-by-Step Guide to Using a Dremel Chainsaw Sharpener Kit
Here’s a detailed guide to using a Dremel chainsaw sharpener kit:
- Secure the Chainsaw: Clamp the chainsaw in a vise or use a stump vise to hold it securely.

- Attach the Grinding Stone: Attach the grinding stone to the Dremel.
- Set the Depth: Adjust the depth guide on the Dremel to the correct setting. This will control the amount of material removed.
- Position the Dremel: Place the Dremel in the cutter, aligning it with the guide. Ensure the grinding stone is at the correct top plate and side plate angles.
- Sharpen the Cutter: Use short, controlled bursts to sharpen the cutter. Avoid applying too much pressure, as this can overheat the chain.
- Sharpen All Cutters: Sharpen all the cutters on one side of the chain, then flip the chainsaw and sharpen the cutters on the other side.
- Check the Depth Gauges: After sharpening the cutters, check the depth gauges. Use a depth gauge tool to measure the height difference between the depth gauge and the cutter. If the depth gauge is too high, use a flat file to lower it.
- Test the Chain: After sharpening, test the chain by making a few cuts. The chain should cut smoothly and efficiently.
The Depth Gauge Dilemma: Rakers Matter!
Don’t underestimate the importance of depth gauges, also known as rakers. They control how deeply the cutter bites into the wood. If the depth gauges are too high, the chain won’t cut effectively. If they’re too low, the chain will be too aggressive and may cause kickback.
- Checking Depth Gauges: Use a depth gauge tool to measure the height difference between the depth gauge and the cutter.
- Adjusting Depth Gauges: If the depth gauge is too high, use a flat file to lower it. File the depth gauge evenly, maintaining its original shape.
Real-World Applications: Sharpening for Different Wood Types
The type of wood you’re cutting can influence your sharpening technique.
- Softwoods (Pine, Fir, Spruce): Softwoods require a more aggressive chain with a lower depth gauge setting. This allows the chain to bite into the wood more easily.
- Hardwoods (Oak, Maple, Ash): Hardwoods require a less aggressive chain with a higher depth gauge setting. This prevents the chain from bogging down in the dense wood.
- Frozen Wood: Sharpening for frozen wood requires extra care. Use a fine-grit file or grinding stone to avoid damaging the chain.
Workflow Optimization: Integrating Sharpening into Your Routine
Sharpening shouldn’t be an afterthought. Integrate it into your regular chainsaw maintenance routine.
- Sharpen Regularly: Sharpen your chain after every few hours of use, or whenever you notice a decrease in cutting performance.
- Clean the Chain: Before sharpening, clean the chain with a brush and solvent to remove dirt and debris.
- Inspect the Chain: Inspect the chain for damage, such as cracks or broken cutters. Replace the chain if necessary.
- Maintain Your Tools: Keep your files and grinding stones clean and sharp. Replace them when they become dull.
Sustainable Timber Selection and Chainsaw Efficiency
Choosing sustainable timber goes hand-in-hand with efficient chainsaw use. Selecting responsibly harvested wood not only benefits the environment but can also impact the longevity of your chainsaw and the frequency of sharpening.
- Density Matters: Denser hardwoods, even when sustainably sourced, can dull a chain faster than softer woods. Being mindful of the wood’s density and adjusting your sharpening schedule accordingly is crucial.
- Contaminants: Sustainably harvested wood is less likely to contain hidden nails, wire, or other contaminants that can severely damage a chainsaw chain.
- Species Selection: Some tree species are naturally easier on chainsaws. For example, cedar tends to be softer and less abrasive than oak.
Case Study: Optimizing Firewood Production with Sharp Chainsaws
I once consulted with a small firewood producer who was struggling to meet demand. Their biggest bottleneck was the time it took to process logs. After analyzing their workflow, I identified that dull chainsaws were a major contributor to their inefficiency.
- The Problem: The producer was only sharpening their chains once a week, regardless of how much they had cut. This resulted in significant downtime and increased fuel consumption.
- The Solution: I implemented a new sharpening schedule, requiring chains to be sharpened at least once a day, or more frequently if needed. I also trained the crew on proper filing techniques.
- The Results: The producer saw a 20% increase in firewood production, a 15% reduction in fuel consumption, and a significant decrease in downtime. This case study highlights the importance of integrating sharpening into your workflow.
Cost Savings and Return on Investment
Investing in proper sharpening equipment and training can yield significant cost savings.
