With the right technique and a few simple tools, you can achieve professional-level sharpness right in your own workshop. This guide is designed for everyone, from the weekend warrior cutting firewood to the seasoned arborist felling trees for a living.
Why a Sharp Chainsaw Matters (More Than You Think)
- Safety First: A dull chain requires more force, increasing the risk of kickback. A sharp chain bites into the wood effortlessly, reducing the chance of accidents.
- Efficiency: A sharp chainsaw cuts faster and requires less effort, saving you time and energy.
- Chainsaw Longevity: Forcing a dull chain puts unnecessary strain on your chainsaw’s engine, shortening its lifespan.
- Cleaner Cuts: A sharp chain produces cleaner, more precise cuts, which is crucial for everything from felling trees to crafting woodworking projects.
- Fuel Efficiency: Believe it or not, a sharp chain actually improves your chainsaw’s fuel efficiency. It requires less power to cut, so you’ll use less gas.
Dremel Chainsaw Sharpening: The Arborist’s Secret Weapon
While file-sharpening is the traditional method, using a Dremel with a chainsaw sharpening stone offers several advantages:
- Precision: A Dremel allows for more precise sharpening, especially on smaller chains.
- Speed: With practice, you can sharpen a chain much faster with a Dremel than with a file.
- Accessibility: A Dremel can reach tight spaces that a file might struggle with.
- Consistency: It’s easier to maintain consistent sharpening angles with a Dremel, leading to a more uniform cut.
What You’ll Need
- Dremel Rotary Tool: A variable-speed Dremel is ideal.
- Chainsaw Sharpening Stone Set: Choose a set with stones that match the size of your chainsaw’s cutters.
- Depth Gauge Tool: To check and adjust the depth gauge (raker) height.
- Flat File: For adjusting the depth gauges.
- Safety Glasses: Essential for protecting your eyes from flying debris.
- Gloves: To protect your hands.
- Vice or Chainsaw Vise: To secure the chainsaw bar.
- Marker: For marking the starting tooth.
Understanding Your Chainsaw Chain
Before you even think about firing up your Dremel, it’s crucial to understand the anatomy of your chainsaw chain. A chainsaw chain isn’t just a loop of metal; it’s a sophisticated cutting tool with several key components:
- Cutters (Teeth): These are the sharp, chisel-like blades that actually do the cutting. Each cutter has a top plate and a side plate, which form the cutting edges.
- Depth Gauges (Rakers): These small projections in front of each cutter regulate how deeply the cutter bites into the wood. They’re crucial for preventing the chain from grabbing too aggressively and causing kickback.
- Tie Straps: These connect the cutters and depth gauges, forming the chain’s backbone.
- Drive Links: These fit into the groove of the chainsaw bar and transmit power from the engine to the chain.
Different Chain Types
- Full Chisel: These chains have square-cornered cutters that offer the fastest cutting speed in clean wood. However, they dull quickly in dirty or abrasive conditions.
- Semi-Chisel: These chains have rounded corners on the cutters, making them more durable and forgiving in less-than-ideal conditions. They’re a good compromise between cutting speed and durability.
- Low-Profile: These chains have a shallower cutting angle and are designed for safety and reduced kickback. They’re often found on smaller, homeowner-grade chainsaws.
Chain Pitch and Gauge
- Pitch: This refers to the size of the chain and is measured as the distance between three consecutive rivets divided by two. Common pitches include .325″, 3/8″, and .404″.
- Gauge: This refers to the thickness of the drive links and must match the groove width of your chainsaw bar. Common gauges include .043″, .050″, .058″, and .063″.
Pro Tip: Always consult your chainsaw’s owner’s manual to determine the correct chain type, pitch, and gauge for your specific model.
The 5 Pro Arborist Secrets for Dremel Chainsaw Sharpening
Okay, let’s get to the meat of the matter. Here are five pro arborist secrets that will elevate your Dremel chainsaw sharpening game:
Secret #1: Mastering the Angle: The Key to a Razor-Sharp Edge
The angle at which you sharpen your chainsaw chain is critical. It determines the aggressiveness and efficiency of the cut. The correct angle varies depending on the chain type and manufacturer’s recommendations, but here are some general guidelines:
- Top Plate Angle: This is the angle between the top plate of the cutter and the side of the chain. Typically, this angle is between 25 and 35 degrees.
- Side Plate Angle: This is the angle between the side plate of the cutter and the direction of chain travel. Typically, this angle is between 60 and 75 degrees.
How to Achieve the Correct Angle with a Dremel
This is where the magic happens. I use a simple trick that makes it easier to maintain the correct angle consistently.
- Visualize the Angle: Before you start sharpening, take a close look at the cutters on your chain. Notice the angle of the top plate and side plate. This will give you a visual reference.
- Use a Guide (Optional): Some Dremel sharpening kits come with a guide that helps you maintain the correct angle. If you have one, use it!
- The “Eyeball” Method (My Preferred Approach): With practice, you can learn to “eyeball” the correct angle. Here’s how:
- Hold the Dremel at a slight angle, aligning the sharpening stone with the top plate of the cutter.
- As you move the Dremel, gradually adjust the angle to match the existing angle of the cutter.
- Pay close attention to the sparks. They should be directed away from you and should be consistent. If the sparks are erratic, it means you’re not holding the Dremel at the correct angle.
- Practice, Practice, Practice: The more you practice, the better you’ll become at maintaining the correct angle. Don’t be afraid to experiment and find what works best for you.
Data Point: Studies have shown that maintaining the correct sharpening angle can increase cutting efficiency by up to 20%.
Secret #2: Depth Gauge Domination: Achieving the Perfect Bite
The depth gauges (rakers) are just as important as the cutters. They control how deeply the cutters bite into the wood. If the depth gauges are too high, the cutters won’t be able to engage properly, and your chainsaw will cut slowly or not at all. If the depth gauges are too low, the chain will grab aggressively, increasing the risk of kickback.
How to Check and Adjust Depth Gauges
- Use a Depth Gauge Tool: This tool has slots that correspond to the correct depth gauge height for different chain pitches. Place the tool over the cutters and depth gauges. If the depth gauges protrude above the tool, they need to be filed down.
- File the Depth Gauges: Use a flat file to carefully file down the depth gauges until they are flush with the depth gauge tool. Be careful not to file them down too much.
- Round the Front Edge: After filing, use the file to slightly round the front edge of the depth gauges. This will help prevent them from digging into the wood.
Pro Tip: It’s better to err on the side of caution when adjusting depth gauges. It’s easier to file them down further than it is to add material back.
Case Study: I once worked with a logger who was struggling to cut through hardwood. After checking his chainsaw, I discovered that his depth gauges were too high. After filing them down to the correct height, his chainsaw cut through the hardwood like butter.
Secret #3: The “Less is More” Philosophy: Gentle Grinding for Lasting Sharpness
When sharpening with a Dremel, it’s tempting to grind aggressively to remove material quickly. However, this is a recipe for disaster. Overheating the cutters can weaken the steel and cause them to dull prematurely.
The Key is Gentle Grinding
- Use a Light Touch: Apply only light pressure to the Dremel. Let the sharpening stone do the work.
- Keep the Dremel Moving: Don’t dwell on one spot for too long. Keep the Dremel moving smoothly and consistently.
- Cool the Cutters: If you notice the cutters getting hot, stop sharpening and let them cool down. You can also dip the chain in water to help cool it down.
- Multiple Passes: It’s better to make several light passes than one heavy pass. This will help prevent overheating and ensure a more consistent sharpening job.
Data Point: Overheating the cutters during sharpening can reduce their lifespan by up to 50%.
Secret #4: Consistency is King: Sharpening Every Cutter Equally
A sharp chainsaw is only as good as its weakest cutter. If some cutters are sharper than others, the chain will cut unevenly and be more prone to kickback.
How to Achieve Consistent Sharpening
- Mark the Starting Tooth: Use a marker to mark the first cutter you sharpen. This will help you keep track of your progress and ensure that you sharpen every cutter.
- Count Your Strokes: Count the number of strokes you make on each cutter. This will help you maintain consistency.
- Compare the Cutters: After sharpening, compare the cutters to each other. They should all look and feel the same. If some cutters are duller than others, go back and sharpen them again.
- Rotate the Chain: Sharpen every other cutter on one side of the chain, then rotate the chain and sharpen the remaining cutters. This will help distribute the heat evenly and prevent the chain from becoming warped.
Pro Tip: Invest in a good quality chainsaw vise. This will make it much easier to hold the chain securely and sharpen it consistently.
Secret #5: The “Touch-Up” Technique: Maintaining Sharpness on the Go
The best way to keep your chainsaw chain sharp is to touch it up frequently. A quick touch-up after each use can prevent the chain from becoming severely dull and extend its lifespan significantly.
How to Touch Up Your Chainsaw Chain
- Inspect the Chain: Before each use, inspect the chain for any damage or dullness. If you notice any problems, address them immediately.
- Sharpen Lightly: Use the Dremel to lightly sharpen each cutter. You don’t need to remove a lot of material. Just a few strokes will do.
- Check the Depth Gauges: Check the depth gauges and file them down if necessary.
- Clean the Chain: After sharpening, clean the chain with a brush and lubricate it with chainsaw oil.
Idiom Alert: An ounce of prevention is worth a pound of cure. A little touch-up now can save you a lot of time and effort later.
Troubleshooting Common Chainsaw Sharpening Problems
Even with the best techniques, you may encounter some problems when sharpening your chainsaw chain. Here are some common issues and how to resolve them:
- Chain Cuts Unevenly: This is usually caused by inconsistent sharpening. Make sure you’re sharpening every cutter equally and maintaining the correct angle.
- Chain Kicks Back: This can be caused by several factors, including dull cutters, depth gauges that are too low, or an incorrect sharpening angle. Check all of these factors and make adjustments as needed.
- Chain Dulls Quickly: This can be caused by overheating the cutters during sharpening, using the wrong type of sharpening stone, or cutting dirty or abrasive wood. Use a light touch when sharpening, choose the correct sharpening stone, and avoid cutting dirty wood whenever possible.
- Dremel Overheats: This is usually caused by using too much pressure or running the Dremel at too high of a speed. Use a light touch and reduce the speed of the Dremel.
Real Example: I was once helping a friend sharpen his chainsaw, and he kept complaining that the chain was dulling quickly. After watching him sharpen, I realized that he was using way too much pressure on the Dremel. I showed him how to use a light touch, and his chain stayed sharp much longer.
Chainsaw Sharpening Stone Selection: Choosing the Right Tool for the Job
Not all chainsaw sharpening stones are created equal. Choosing the right stone for the job is crucial for achieving optimal results. Here’s a breakdown of the different types of chainsaw sharpening stones and their uses:
- Aluminum Oxide Stones: These are the most common type of chainsaw sharpening stone. They’re relatively inexpensive and work well on most types of chainsaw chains.
- Silicon Carbide Stones: These stones are harder and more aggressive than aluminum oxide stones. They’re ideal for sharpening very dull or damaged chains.
- Diamond Stones: These stones are the most expensive and durable option. They’re ideal for sharpening carbide-tipped chains.
Stone Grit
The grit of the sharpening stone refers to the size of the abrasive particles on the stone. A coarser grit is used for removing material quickly, while a finer grit is used for honing and polishing the cutting edge.
- Coarse Grit (60-80): Used for sharpening very dull or damaged chains.
- Medium Grit (100-120): Used for general sharpening.
- Fine Grit (220-400): Used for honing and polishing the cutting edge.
Pro Tip: For most chainsaw sharpening jobs, a medium-grit aluminum oxide stone is a good choice. If you’re sharpening a very dull or damaged chain, you may want to start with a coarse-grit stone and then finish with a medium-grit stone.

From Tree to Firewood: A Holistic Approach to Wood Processing
Sharpening your chainsaw is just one piece of the puzzle. To truly master wood processing, you need to understand the entire process, from felling trees to stacking firewood.
Felling Trees Safely
Felling a tree is a dangerous task that should only be attempted by experienced individuals. Here are some basic safety guidelines:
- Assess the Tree: Before felling a tree, carefully assess its size, shape, lean, and any potential hazards, such as dead limbs or power lines.
- Plan Your Escape Route: Clear a path behind you that you can use to escape if the tree falls unexpectedly.
- Make a Notch: Cut a notch on the side of the tree facing the direction you want it to fall. The notch should be about one-third of the tree’s diameter.
- Make a Back Cut: Cut a back cut on the opposite side of the tree, slightly above the notch. Leave a hinge of wood between the notch and the back cut to control the direction of the fall.
- Use Wedges: If necessary, use wedges to help direct the fall of the tree.
- Yell “Timber!”: Before the tree falls, yell “Timber!” to warn anyone in the area.
Technical Requirements: Always wear a hard hat, safety glasses, hearing protection, and chainsaw chaps when felling trees.
De-limbing and Bucking
Once the tree is on the ground, you’ll need to de-limb it (remove the branches) and buck it (cut it into manageable lengths).
- De-limbing: Use your chainsaw to carefully remove the branches. Be careful not to cut into the trunk of the tree.
- Bucking: Use your chainsaw to cut the trunk into lengths suitable for firewood. The length will depend on the size of your fireplace or wood stove.
Best Practices: When de-limbing and bucking, always stand on the uphill side of the log to avoid being pinned by a rolling log.
Splitting Logs
Splitting logs can be done manually with an axe or maul, or with a hydraulic log splitter.
- Manual Splitting: Place the log on a chopping block and swing the axe or maul down on the log. Aim for the center of the log or any existing cracks.
- Hydraulic Log Splitter: Place the log on the log splitter and activate the hydraulic ram. The ram will push the log against a splitting wedge.
Actionable Tips: When splitting logs manually, wear safety glasses and gloves to protect your eyes and hands. When using a hydraulic log splitter, follow the manufacturer’s instructions carefully.
Seasoning Firewood
Seasoning firewood is essential for reducing its moisture content and making it burn more efficiently.
- Stack the Firewood: Stack the firewood in a single row, allowing air to circulate freely around the logs.
- Elevate the Stack: Elevate the stack off the ground to prevent moisture from wicking up into the logs.
- Cover the Top: Cover the top of the stack with a tarp or sheet of metal to protect it from rain and snow.
- Allow Time to Season: Allow the firewood to season for at least six months, or preferably a year.
Moisture Content Targets: The ideal moisture content for firewood is between 15% and 20%. You can use a moisture meter to check the moisture content of your firewood.
Data Point: Seasoning firewood can reduce its moisture content by up to 50%, making it burn hotter and cleaner.
Different wood species have different densities, moisture contents, and burning characteristics.
Hardwoods vs. Softwoods
- Hardwoods: These woods are denser and burn longer than softwoods. They also produce more heat. Examples include oak, maple, ash, and birch.
- Softwoods: These woods are less dense and burn faster than hardwoods. They also produce more smoke. Examples include pine, fir, and spruce.
Specific Wood Species
- Oak: Excellent firewood. Burns long and hot.
- Maple: Good firewood. Burns well and produces a pleasant aroma.
- Ash: Excellent firewood. Burns clean and produces little smoke.
- Birch: Good firewood. Burns quickly and produces a bright flame.
- Pine: Not ideal for firewood. Burns quickly and produces a lot of smoke.
Unique Insights: The best firewood is a mix of hardwoods and softwoods. Hardwoods provide long-lasting heat, while softwoods provide quick ignition and a bright flame.
