Best Chainsaw Chain for Firewood (Australia)
Share
Cutting firewood is a different job to felling a tree. The wood is usually dry and seasoned, the logs are often sitting in the dirt, and you're making hundreds of crosscuts in a session instead of a few big felling cuts. That combination chews through chains faster than just about any other kind of cutting.
This guide covers which chain actually holds up, why semi-chisel beats full chisel for firewood, why a GoldStrike tungsten carbide chain is the pick for dirty or seasoned logs, and which chain size fits the most common firewood saws in Australia.
Why Firewood Cutting Is So Hard on Chains
Plenty of people buy a chain that handles green timber fine, then wonder why it goes blunt halfway through a trailer load of firewood. Three reasons.
Seasoned wood is harder than green wood
When timber dries out, the fibres harden and the moisture that used to lubricate the cut is gone. A red gum log that cut easily when it was green will be noticeably tougher after a year or two of seasoning, and most firewood in Australia is seasoned hardwood. If you're felling green, standing timber instead, that's a different job with different priorities, our guide to the best chainsaw chain for Australian hardwood covers that side of things.
Firewood logs live on the ground
This is the big one. Felled logs sit in dirt, get dragged across paddocks, and carry grit in the bark. Dirt is the number one chain killer, one pass through a gritty patch of bark can round off the cutters on a standard chain. Sand and soil are abrasive enough to take the edge off chrome-plated steel almost instantly, and once the cutters are rounded, the chain rubs instead of cuts.
Firewood is hundreds of cuts, not a few
Felling a tree is a handful of cuts. Blocking up a winter's worth of firewood is hundreds of full-depth crosscuts, session after session, through the densest part of the log. Even in clean wood, that volume of cutting wears an edge down fast.
Semi-Chisel vs Full-Chisel for Firewood (The Short Answer)
Cutter profile matters more for firewood than almost any other job. Here's the quick version:
| Semi-chisel | Full-chisel | |
|---|---|---|
| Cutter shape | Rounded working corner | Square working corner |
| Fastest in | Holds speed in dry, dirty wood | Clean, green softwood |
| Edge life in seasoned/dirty wood | Good, the rounded corner resists damage | Poor, dulls quickly on dirt and dry grain |
| Firewood verdict | The pick | Skip it |
Full-chisel cuts faster while it's sharp, but seasoned hardwood and dirty bark take that edge off quickly, and then it's slower than a semi-chisel that's still cutting. For firewood, semi-chisel is the most common option for good reason. If you want the full breakdown, read our semi-chisel vs full-chisel comparison.
Why Tungsten Carbide Is the Firewood Pick
A standard steel chain is fine for occasional cutting in clean wood. The trouble is, firewood is rarely clean, and that's exactly where tungsten carbide tipped chains earn their keep.
The cutters are tipped with tungsten carbide, one of the hardest materials you can put on a chain. In firewood terms that means:
- Up to 10x longer edge life than a standard chain before it needs sharpening
- Keeps cutting after dirt contact: the grit that would kill a standard chain barely slows carbide down
- Handles seasoned hardwood: dry red gum, box, and ironbark don't round the cutters off the way they do on steel
- Fewer sharpening stops: the saw keeps pulling proper chips instead of dust, so you finish the load instead of finishing at the bench
For a firewood cutter, the maths is simple. If you're going through several standard chains a season, or spending half your cutting time sharpening, one carbide chain that just keeps cutting works out cheaper and faster. Most tungsten carbide chains also come in a semi-chisel profile, so you get the right cutter shape and the harder edge in one chain. For the full side-by-side, see our tungsten carbide vs standard chain comparison.
When a standard chain still makes sense
If you only cut a few clean, green logs a year off a saw horse, a quality standard chain will do the job and costs less upfront, our TUFOZI standard chain range covers that. But if your logs touch the ground, your wood is seasoned, or you cut more than the odd weekend, carbide is the better buy.
Matching the Chain to Your Firewood Saw
Whatever chain type you choose, it has to match your saw on three measurements: pitch (link size), gauge (drive link thickness), and drive link count (chain length). All three are usually stamped on your guide bar near the saw body.
Quick gauge note: 3/8" .063" (1.6 mm) is the Stihl spec, while .058" (1.5 mm) is the Husqvarna spec, don't mix them up, the chain won't sit in the bar groove properly.
Here are the most common firewood saws in Australia and the chain each one takes:
| Saw | Bar | Pitch | Gauge | Drive links |
|---|---|---|---|---|
| Stihl MS 170 / MS 180 | 16" | 3/8" LP | .043" (1.1 mm) | 55 |
| Husqvarna 120 / 135 / 235 / 240 | 16" | 3/8" LP | .050" (1.3 mm) | 56 |
| Stihl MS 250 / MS 251 | 16" | .325" | .063" (1.6 mm) | 62 |
| Husqvarna 435 / 440 | 16" | .325" | .058" (1.5 mm) | 66 |
| Stihl MS 271 / MS 291 Farm Boss | 18" | .325" | .063" (1.6 mm) | 74 |
| Husqvarna 450 Rancher | 18" | .325" | .058" (1.5 mm) | 72 |
| Husqvarna 455 Rancher | 20" | 3/8" | .058" (1.5 mm) | 72 |
| Stihl MS 311 / MS 391 | 20" | 3/8" | .063" (1.6 mm) | 72 |
| Echo CS-590 Timber Wolf | 20" | 3/8" | .058" (1.5 mm) | 72 |
Mid-size farm saws on .325" pitch are probably the most common firewood setup going, browse .325 pitch chainsaw chains here. Bigger saws on full 3/8" pitch are covered in our 3/8 pitch chainsaw chain range.
How to Pick: The Quick Flow
- Find your specs. Check the stamp on your guide bar, or read the numbers off your old chain. You need pitch, gauge, and drive link count.
- Cutting seasoned wood, logs off the ground, or a full winter's supply? Go a tungsten carbide semi-chisel chain in your specs. That's the most common option for firewood and the one we'd run ourselves.
- Only cutting occasional clean, green wood off a saw horse? A standard semi-chisel chain will do fine.
- Not sure? Send us a photo of your bar markings or your saw model and we can sort it out pretty quickly.
Looking After Your Chain Between Firewood Runs
Even a carbide chain lasts longer with a bit of care. A few habits that make a real difference:
- Keep the chain out of the dirt. Roll logs onto a bearer or saw horse, knock the worst of the mud and grit off the bark, and never let the bar nose run into the ground at the end of a cut.
- Check tension often. Hundreds of crosscuts heat the chain up and stretch it. A loose chain wears the bar, cuts crooked, and is dangerous.
- Don't skimp on bar oil. Dry wood generates more heat than green wood, so keep the oiler topped up and check it's actually feeding.
- Clean the bar groove and flip the bar every few sessions to even out rail wear, compacted dry sawdust packs into the groove harder than green sawdust does.
- Sharpen at the first sign of dust. Sharp chains pull proper chips. Once you're seeing fine dust and having to lean on the saw, stop and sharpen, a standard chain takes a round file, while carbide needs a diamond sharpener. Our chainsaw chain maintenance guide and how to sharpen a chainsaw chain walk through both.
FAQ
What's the best chainsaw chain for cutting seasoned firewood?
A semi-chisel tungsten carbide chain in your saw's pitch and gauge. Seasoned hardwood is harder and more abrasive than green wood, and carbide cutters hold their edge up to 10x longer than standard steel, so you spend the session cutting, not sharpening.
Is full chisel or semi chisel better for firewood?
Semi-chisel. Full-chisel is faster in clean green softwood, but firewood is usually dry, often dirty, and both of those things blunt a full-chisel edge quickly. The rounded corner on a semi-chisel cutter holds up much better in real firewood conditions.
Why does my chain go blunt so fast cutting firewood?
Almost always dirt. Logs that have been sitting on the ground carry grit in the bark, and one gritty cut can round off standard cutters. Dry seasoned hardwood speeds the dulling up further. Lift your logs off the ground, knock the bark clean, and consider a tungsten carbide chain if it keeps happening.
Will a tungsten carbide chain fit my saw?
If the pitch, gauge, and drive link count match your bar, yes, carbide chains come in the same configurations as standard chains, from small 16" homeowner saws up to big farm saws. Check the table above or send us your saw model.
How often should I sharpen when cutting firewood?
With a standard chain in seasoned hardwood, you might be touching it up every tank or two of fuel, sooner if you've hit dirt. A carbide chain goes up to 10x longer between sharpens, and needs a diamond sharpener rather than a round file when the time comes.
TL;DR: Quick Reference
- Firewood is harder on chains than felling: seasoned wood, dirty logs, hundreds of crosscuts.
- Cutter profile: semi-chisel, not full-chisel.
- Chain type: tungsten carbide for seasoned or off-the-ground logs, up to 10x the edge life, keeps cutting after dirt contact. Standard is fine for occasional clean green wood.
- Fitment: match pitch, gauge, and drive links off your bar stamp. 3/8" .063" (1.6 mm) = Stihl spec, .058" (1.5 mm) = Husqvarna spec.
- Care: keep the chain out of the dirt, watch tension, sharpen at the first sign of dust.
