DeWalt 60V Max Flexvolt Chainsaw Review: The Battery-Powered Beast That Defies Convention

Let’s get one thing straight: I’ve spent the better part of fifteen years smelling like 50:1 premix and bar oil. I’ve owned every legendary saw from the Stihl MS 261 to the Echo CS-590 Timber Wolf. For a long time, the idea of a battery-powered chainsaw was, frankly, a joke—a toy for people who needed to trim a few stray branches on a Sunday afternoon.

But the DeWalt 60V Max Flexvolt isn’t a toy. It’s a statement.

When I first lugged this yellow-and-black unit out into a stand of downed Hickory after a late-season storm, I was skeptical. I expected it to bog down the moment I buried the dogs into the bark. Instead, I found a tool that challenged my fundamental understanding of “lugging power.” This isn’t just an electric motor; it’s a high-torque system designed to mimic the grunt of a 40cc to 50cc gas engine.

In this teardown, we are going to look past the marketing fluff. We’re going into the MOSFETs, the thermal throttling, the ergonomics of that oversized battery, and how it holds up when the temperature drops and the wood gets hard.

Strategic Comparison: The Battery vs. Gas Power Struggle

Before we dissect the internals, let’s see how this Flexvolt monster stacks up against the established hierarchy of prosumer saws.

Technical Engineering Deep-Dive: The “Engine” That Never Idles

When we talk about gas saws, we talk about port timing, magnesium crankcases, and air filtration. With the DeWalt 60V, we have to shift our vocabulary toward electronics and electromagnetism.

The Brushless Heart

The DeWalt 60V utilizes a high-efficiency brushless motor. In a traditional brushed motor, you have physical contact (brushes) that creates friction, heat, and eventually, failure. By going brushless, DeWalt allows the saw to electronically commute the magnetic field. This results in nearly 90% efficiency compared to the 70% seen in older DC motors.

What does this mean in the cut? It means torque. The moment you pull that trigger, you get maximum torque. There is no “spool-up” time like you find on the Echo CS-310. You hit the trigger, and the chain is instantly at its peak surface feet per minute (SFM).

The Flexvolt Secret Sauce

The “Flexvolt” branding isn’t just a gimmick. The engineering behind the battery pack is actually quite brilliant. These batteries are designed to switch between 20V (parallel) and 60V (series) depending on the tool they are plugged into. Inside the 60V chainsaw, the battery connects in a way that pulls a massive amount of current across all cells simultaneously.

However, heat is the enemy of any battery system. During my testing, I noticed that the saw uses a sophisticated MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) controller. This controller monitors the thermal load of the battery cells and the motor windings. If you’re buried in a 14-inch log of frozen white oak and you’re leaning on the saw too hard, the electronics will actually “throttle” the power to prevent the motor from melting its own insulation. It’s a “brain” that gas saws like the Husqvarna 130 simply don’t have.

The Bar and Chain Geometry

DeWalt ships this with an Oregon-branded 16-inch bar (though an 18-inch is available). The chain is a low-profile, 3/8” pitch, .050” gauge. For the hardcore loggers out there, this might seem “dainty.” But there’s a reason for it: Kerf.

A narrower kerf (the width of the cut) means the motor has to remove less wood material to make its way through the log. If you were to put a heavy-duty .325” pitch chain from a Stihl MS 271 on this, you’d likely kill the battery in ten minutes. The engineering choice here is a balance between cutting speed and energy conservation.

Real-World Performance: Bucking, Limbing, and the Sound of Silence

I took the 60V Max into a woodlot in Northern Michigan. The task was simple: buck up a fallen Sugar Maple for firewood.

The Torque Curve

In a gas saw, you have a specific power band. You need to keep the RPMs high to keep the torque up. If the RPMs drop, the saw stalls. With the DeWalt, the torque curve is almost flat. I purposely tried to stall the saw by pushing down with about 20 pounds of force mid-cut. The electronics didn’t stall; they growled. The motor pulsed as the controller pushed more “juice” to maintain chain speed. It felt less like a mechanical tool and more like an industrial force of nature.

Limbing Efficiency

This is where the DeWalt 60V absolutely destroys gas saws like the Echo CS-400. When you’re limbing, you spend a lot of time moving branches, repositioning your feet, and checking your surroundings. With a gas saw, you’re either idling (wasting fuel and inhaling fumes) or you’re restarting the saw.

With the DeWalt, the silence between cuts is therapeutic. You make a cut, the chain stops instantly (thanks to the electronic brake), and you can hear the birds. You move the branch, pull the trigger, and you’re back in the wood. The reduction in operator fatigue from the lack of vibration and noise cannot be overstated. After four hours of limbing, my hands didn’t have that “tingling” sensation that usually follows a session with my Husqvarna 435.

Bore-Cutting and Felling

I wouldn’t recommend this as your primary felling saw for 20-inch hardwoods, but for anything under 12 inches, it’s remarkably capable. I performed a bore cut to test the kickback and the nose geometry. The Oregon chain is a “low-kickback” design, which makes it a bit sluggish when trying to initiate a plunge cut, but it’s safe. The balance of the saw remains consistent even as the battery drains—unlike a gas saw where the balance shifts as the fuel tank empties.

Ergonomics & Operator Comfort: The Yellow Architecture

DeWalt’s design language is very “construction-site.” Everything is chunky, rubberized, and designed to be used with heavy gloves.

1. The Wrap Handle: It’s a thick, plastic-molded handle with a decent rubber overmold. It’s wider than the handle on the Stihl MS 170, which gives you better leverage for lateral cuts.
2. Weight Distribution: The saw is “tail-heavy” because of the 9.0Ah or 12.0Ah battery. When you’re holding it at your side, the bar naturally wants to point up. However, once the bar is in the wood, that weight helps you apply downward pressure.
3. The Chain Brake: It has a satisfying, mechanical “clunk.” It’s an inertia-activated brake, meaning if the saw kicks back, the force will trip the brake even if your hand doesn’t hit the guard.
4. The Oil Cap: This is a weak point. It’s a screw-on cap that can be a bit finicky to thread when it’s covered in sawdust and oil. I much prefer the “flip-cap” design found on modern Stihl models.

Historical Context: From “Yellow Tools” to “Logging Tools”

DeWalt’s journey into the chainsaw world was rocky. Their early 40V attempts were essentially glorified hedge trimmers. They were underpowered and the batteries overheated constantly.

The 60V Max Flexvolt represents the “Redemption Era” for DeWalt’s Outdoor Power Equipment (OPE) line. They stopped trying to compete with “homeowner” electric saws and started aiming at the prosumer gas market occupied by the Husqvarna 440. This saw shares DNA with their high-end hammer drills and impact drivers—tools designed to be dropped, kicked, and worked hard.

By utilizing the Flexvolt battery, DeWalt solved the biggest hurdle of electric saws: the ecosystem. If you already own DeWalt’s 60V circular saw or grinder, the barrier to entry for this chainsaw is non-existent. You buy the “tool-only” and you’re ready to clear brush.

Maintenance & Serviceability: The “No-Mix” Lifestyle

One of the biggest selling points of the DeWalt 60V is what you don’t have to do.

• No Spark Plugs: You’ll never spend 20 minutes in the woods pulling a cord and wondering if your plug is fouled.
• No Air Filter Cleaning: While there are cooling vents that you should blow out with compressed air occasionally, there is no pleated paper filter to get clogged with fine dust.
• No Fuel Mixing: This is the big one. No more storing stabilizing fuel, no more “is this 40:1 or 50:1?” confusion.

The “Maintenance” you do need to do:

1. Bar Oil: This saw is a “thirsty” oiler. It goes through bar and chain oil faster than most gas saws I’ve used. Check the reservoir every time you swap the battery.
2. Chain Tensioning: The DeWalt uses a dual-nut retention system for the bar. I much prefer this over the “tool-less” tensioners found on the Husqvarna 120. Tool-less tensioners tend to back off under heavy load; the DeWalt’s nuts stay put.
3. Battery Contacts: Keep the contacts clean. If sawdust gets packed into the battery terminal, you’ll get intermittent power loss. A quick blast of air or a wipe with a dry cloth fixes it.

Pros & Cons: The SAWOFF Edge

Pros

• Instantaneous Power: No warm-up, no idling, just pure torque the moment you need it.
• Quiet Operation: Perfect for suburban neighborhoods or areas with noise ordinances. You won’t wake the neighbors at 7 AM.
• Zero Emissions: No breathing in blue smoke while you’re hunched over a log.
• Flexvolt Ecosystem: If you are already on the DeWalt platform, this is a no-brainer.
• Metal Dogs: Real metal bucking spikes that actually bite into the wood, unlike the plastic nubs on the Echo CS-352.

Cons

• Oil Leakage: Like many DeWalt saws, this one likes to “mark its territory” in the garage. If you store it with oil in the reservoir, expect a puddle.
• Weight: With a 12.0Ah battery, this saw is heavier than a Stihl MS 261, which has significantly more cutting power.
• Thermal Cutoff: On extremely hot days (95°F+), if you are pushing the saw hard in thick hardwood, the battery will go into thermal protection mode and shut down until it cools.
• Bar Guard: The plastic housing around the bar nuts feels a bit “consumer-grade” compared to the magnesium covers on pro-level gas saws.

Final Verdict: Is It “Pro-Grade”?

The DeWalt 60V Max Flexvolt is the best “farm and ranch” saw for the person who doesn’t want to deal with the headaches of internal combustion. It is perfect for storm cleanup, trail maintenance, and bucking firewood.

However, it is not a replacement for a 60cc professional saw like the Echo CS-590 if you are dropping 30-inch oaks all day. The battery technology just isn’t there yet for 8-hour-a-day, high-intensity logging.

But for the 90% of users who need a reliable, powerful tool that works every time they pull the trigger, this is the gold standard of cordless. It has the “snap,” it has the “growl,” and it has the “muscle” to get the job done.

SAWOFF Rating: 4.6 / 5

FAQ: Everything You Need to Know

1. How long does the battery actually last?

In my experience, a 9.0Ah Flexvolt battery will give you about 60 to 70 cuts in 6-inch diameter pine. If you are bucking 12-inch oak, expect that to drop to around 30-40 cuts. It’s always best to have two batteries on the charger if you’re doing serious work.

2. Can I use a 20V Max battery in this saw?

No. The 60V tools require the Flexvolt batteries. While Flexvolt batteries work in 20V tools, 20V batteries do not work in 60V tools like this chainsaw.

3. Does it require special bar oil?

No, any high-quality bar and chain oil will work. I recommend a “tackier” oil in the summer to prevent it from flinging off the chain at high speeds.

4. Why is my DeWalt 60V leaking oil?

This is a common complaint. The gravity-fed oiling system on these saws doesn’t have a perfect seal when the saw is sitting. To prevent this, store the saw on its side (oil cap up) or drain the oil if you aren’t going to use it for a few months.

5. Can I put an 18-inch bar on the DeWalt 60V?

Yes, you can. DeWalt even sells a version with an 18-inch bar. However, keep in mind that the longer the bar, the more friction the motor has to overcome, which will slightly reduce your battery runtime.

6. How does the chain speed compare to a gas saw?

The DeWalt 60V has a chain speed of about 15 m/s. For comparison, a professional gas saw like the Stihl MS 261 clocks in at over 25 m/s. The DeWalt compensates for the slower speed with higher torque—it doesn’t “zip” through wood, it “grinds” through it.

7. Is the chain brake electronic or mechanical?

It’s both. There is a physical mechanism that stops the chain via a brake band, but there is also an electronic cut-off that kills power to the motor the instant the brake is engaged.

8. What is the “SAWOFF” tip for this saw?

Replace the stock Oregon 90PX chain with a slightly higher-quality semi-chisel chain once it wears out. You’ll find the saw stays sharper longer in “dirty” wood (wood with mud or sand on the bark). Just make sure you match the gauge (.050”) exactly.
