Best Chainsaw for Milling: What Power, Bar Length, and Setup Do You Actually Need?
If you are looking for the best chainsaw for milling, the right answer depends on the size of the logs you want to cut, how often you mill, and how much weight you want to handle. Bigger is not always better. For many people, a lighter professional saw is the better long-term choice.
Chainsaw milling puts much more strain on a saw than normal cross-cutting. You are making long rip cuts with more friction, more heat, and more constant load on the engine, bar, and chain. That is why a saw that feels strong enough for firewood may feel underpowered when milling boards or slabs.
How Much Power Do You Need for Chainsaw Milling?
A practical minimum for chainsaw milling is around 50 cc / 3 kW with at least an 18-inch (450 mm) bar. That is enough for many small to medium logs, especially if your chain is sharp and your setup is efficient.
For regular milling, many users prefer something in the 60–80 cc range. These saws have more reserve power, which helps keep cuts smoother and faster, especially in hardwood or wider slabs.
If you plan to mill large logs often, or want to run longer bars, then an 80 cc+ chainsaw starts to make more sense. These larger saws are faster in demanding cuts, but they also cost more, use more fuel, and are more tiring to handle.
What Bar Length Is Best for Milling?
The best bar length for milling depends on the size of the logs you actually want to mill.
- 18-inch (450 mm) bar: good for smaller logs and lighter setups
- 20-inch (500 mm) bar: a very practical all-round choice
- 24–28-inch (600–700 mm) bar: better for wider logs, but requires more power
- 28-inch+ (700 mm and above) bar: usually best with larger professional saws
A longer bar does not automatically mean better milling. If the powerhead is too small for the bar and the wood, cutting becomes slow, rough, and harder on both the saw and the operator.
What Setup Matters Most?
The chainsaw is only one part of a good milling setup. For better results, focus on the full system:
- a sharp chain suitable for ripping cuts
- good chain lubrication
- a stable mill that is easy to set up accurately
- realistic matching of saw size to log size
In practice, a well-matched medium saw with a sharp chain often performs better than an oversized setup used badly.
Gas vs Electric Chainsaw for Milling
Gas chainsaws are still the most common choice for milling, especially for larger logs and long work sessions. They are easier to refuel in the field and there are more high-power options available.
But electric chainsaws are now a real option for some users. They are quieter, easier to start, and lower-maintenance. Their main limits are runtime and battery cost, especially if you want to mill for long periods.
One good example is Swamp Road Baskets, who shares several videos of cutting lumber with a Nature Tools ClampMill and an electric chainsaw. You can see the channel here: youtube.com/@swamproadbaskets.
Which Chainsaws Do We Actually Use?
For smaller and medium-sized milling work, Mattias mostly uses a Stihl MS261. It is a good example of a saw that sits close to the practical minimum while still being powerful enough for real milling work.
For larger and more demanding jobs, Donald has lately been using a Stihl MS500i. When you choose a bigger chainsaw for milling, the work usually gets faster, smoother, and more enjoyable. Donald’s Stihl MS500i shows how a high-power setup can make even large projects, like milling lumber for a cabin, feel practical and fun.
Here is a video of Donald milling with his MS500i:
What Is the Best Chainsaw for Milling?
For most people, the best chainsaw for milling is a good professional saw in the 50–60 cc range with an 18–20 inch bar. That size is often the best balance of power, weight, cost, and everyday usability.
If you mill larger logs regularly, step up to a bigger saw. If you mill smaller logs and value simplicity, a mid-size saw may be the smarter choice. And if you prefer lower noise and less maintenance, an electric saw can also be a valid option today.
The best chainsaw milling setup is the one that matches your real use: enough power, enough bar length, a sharp chain, and a system that makes milling straightforward and repeatable.
Frequently Asked Questions
What size chainsaw is best for milling?
For most people, a professional chainsaw in the 50–60 cc range with an 18–20 inch bar is the best balance for chainsaw milling.
Can you mill with a 50cc chainsaw?
Yes, a 50 cc chainsaw can work well for milling small to medium logs, especially with a sharp ripping chain and a good milling setup.
Is an electric chainsaw good for milling?
An electric chainsaw can be good for milling smaller logs and shorter sessions. Its main limits are battery runtime and sustained power in longer cuts.
Do you need a ripping chain for chainsaw milling?
A ripping chain or a chain sharpened for ripping cuts usually gives smoother results and is better suited to chainsaw milling than a standard cross-cutting setup. That said, we often use a regular chain ourselves, and for many smaller milling setups it works well. Where a ripping chain tends to matter more is on bars over 22 inches, where smoother cutting and lower strain become more important.
