Stihl MS 180 Chain Size: What Chain Fits (Australia Guide)
Share
Chain stretched, dull, or thrown a tooth? If you've got a Stihl MS 180, here's the good news: it's one of the easiest saws in the country to buy a chain for, because nearly every MS 180 sold in Australia runs the same spec. You'll find replacement chains in our chainsaw chains and bars collection — but give this guide two minutes first so you order the right one the first time.
The Quick Answer — MS 180 Chain Specs
The MS 180 is a 32 cc homeowner saw, and it runs a low profile chain. Here's the full spec:
| Bar length | Pitch | Gauge | Drive links | Chain type |
|---|---|---|---|---|
| 14" | 3/8" LP | .043" (1.1 mm) | 50 | Low profile |
| 16" | 3/8" LP | .043" (1.1 mm) | 55 | Low profile |
In Australia, the 16 inch bar is the common setup, so most MS 180 owners need a 3/8" LP pitch, .043" (1.1 mm) gauge, 55 drive link chain. If you've got the shorter 14 inch bar, the only thing that changes is the drive link count — 50 instead of 55. Pitch and gauge stay the same.
Handy to know: the 16 inch MS 180 chain is the same chain that fits the Stihl MS 170, MS 171 and MS 181 on their 16 inch bars — all four saws run 3/8" LP, .043" (1.1 mm), 55 drive links. If you've also got an MS 170 in the shed, see our Stihl MS 170 chain size guide — one spare chain covers both saws.
What the Three Numbers Actually Mean
Every chainsaw chain is defined by three measurements, and all three have to match your bar. Two out of three doesn't cut it — literally. If you want the full deep-dive, our pitch, gauge and drive links explained guide covers it properly, but here's the short version for the MS 180.
Pitch — 3/8" LP
Pitch describes the size of the chain's links. The MS 180 runs 3/8" LP, where LP stands for low profile — a lighter, narrower-cutting chain made for smaller saws. Be careful here: standard 3/8" pitch chain also exists, it's a physically bigger chain for bigger saws, and the two do not interchange. If your bar stamp shows "3/8 P", that P is Stihl's marking for low profile — same thing as 3/8" LP.
Gauge — .043" (1.1 mm)
Gauge is the thickness of the drive links — the tabs on the underside of the chain that sit down inside the bar groove. The MS 180 uses .043" (1.1 mm) gauge, the thinnest of the common gauges. A .050" (1.3 mm) chain won't seat in the MS 180's groove properly, and a chain that doesn't sit right in the groove isn't safe to run.
Drive links — 50 or 55
The drive link count sets the chain's overall length. Chains aren't sold by bar inches alone — a "16 inch chain" only fits if the drive link count matches too. For the MS 180 that's 50 drive links on the 14 inch bar and 55 drive links on the 16 inch bar.
MS 180 vs MS 180 C — What the Letters Mean
Stihl's model naming trips up a lot of owners. You'll see saws badged MS 180, MS 180 C and MS 180 C-BE, and people understandably wonder whether the chains are different.
Plain English version: the letters after the number refer to different versions of the saw, not a different model family. Our fitment data covers the MS 180 itself — the specs in the table above. If your saw is badged MS 180 C or MS 180 C-BE, don't guess from the badge: the saw will tell you exactly what it runs. Read the bar stamp, or send us a photo of the bar and chain and we can usually confirm it in a couple of minutes.
How to read your bar stamp
Every guide bar has its spec stamped or etched near the tail end — the end closest to the engine, usually around the bar bolts. You're looking for three things:
- A pitch marking — on an MS 180 bar, typically "3/8 P" (that's 3/8" LP)
- A gauge marking — shown as 1.1 mm, .043, or both
- A drive link count — e.g. "55"
If the stamp has worn off — common on older saws that have had a hard life — the chain itself is your backup: count the drive links using the steps below. Or honestly, just photograph both sides of the bar plus the chain and send it through. We do this for customers every week.
How to Count Drive Links
If you're not sure which bar your MS 180 has, counting the drive links on the old chain takes about a minute:
- Take the chain off the saw (saw off, cooled down).
- Find the drive links — the fin-shaped tabs on the inside of the loop that run in the bar groove. These are what you count, not the cutters on top.
- Mark one drive link with chalk, a paint pen or a zip tie.
- Work around the loop counting every drive link until you're back at your mark.
- Got 50? You've got the 14 inch bar. Got 55? That's the 16 inch.
If your count comes up as something else entirely, a previous owner may have fitted a non-standard bar — go with what's stamped on the bar, not what the saw "should" run. And if the bar itself is on the way out (flared rails, pinched groove, heavy wear on the underside), it's often better value to replace bar and chain together — have a look at our chainsaw bar and chain combos.
Standard vs Tungsten Carbide on the MS 180
The MS 180 ships with standard low profile chain, and for light pruning and the occasional weekend job, standard chain is fine — it's cheap and it cuts well when it's sharp. The catch is the "when it's sharp" part. Australian conditions are hard on chain: dry hardwood, dusty logs, bark full of grit. Standard chain dulls fast, so you either sharpen often (our chainsaw sharpening guide shows you how) or you put up with a slow, smoky cut.
The upgrade worth knowing about is tungsten carbide tipped chain. Carbide-tipped cutters hold their edge through dirty firewood and seasoned hardwood, lasting up to 10x longer than standard chain between sharpens. If most of your MS 180's work is cutting firewood, that's the difference between touching the chain up every couple of tanks and barely thinking about it for the season. See the full comparison in our tungsten carbide vs standard chain guide, or browse the GoldStrike tungsten carbide range — and if you can't spot your spec listed, ask us and we'll point you in the right direction.
Common Mistakes That Catch MS 180 Owners Out
These are the ones we see most often:
- Buying by bar length alone. "16 inch chain" covers dozens of different chains. Pitch, gauge and drive links all have to match — length by itself tells you almost nothing.
- Grabbing an MS 211 chain. Same 16 inch bar, same 3/8" LP pitch, even the same 55 drive links — but the MS 211 runs .050" (1.3 mm) gauge, not the MS 180's .043" (1.1 mm). They look near identical on the shelf and they are not interchangeable.
- Assuming every Stihl runs the same chain. The MS 230 and MS 250 run .325" pitch in .063" (1.6 mm) gauge — a completely different chain. Bigger farm saws are different again: see our Stihl Farm Boss chain size guide if there's an MS 271 or MS 291 in the shed too.
- Mixing up 3/8" LP and standard 3/8". Same fraction, very different chain. The MS 180 takes low profile only.
- Counting cutters instead of drive links. The drive links are the fins underneath that ride in the bar groove. Count those.
Here's how the MS 180 sits against the other common 16 inch Stihls:
| Model (16" bar) | Pitch | Gauge | Drive links |
|---|---|---|---|
| MS 170 | 3/8" LP | .043" (1.1 mm) | 55 |
| MS 171 | 3/8" LP | .043" (1.1 mm) | 55 |
| MS 180 | 3/8" LP | .043" (1.1 mm) | 55 |
| MS 181 | 3/8" LP | .043" (1.1 mm) | 55 |
| MS 211 | 3/8" LP | .050" (1.3 mm) | 55 |
| MS 230 | .325" | .063" (1.6 mm) | 62 |
| MS 250 | .325" | .063" (1.6 mm) | 62 |
| MS 271 Farm Boss | .325" | .063" (1.6 mm) | 67 |

FAQ
What size chain fits a Stihl MS 180?
A 3/8" LP pitch, .043" (1.1 mm) gauge low profile chain — 50 drive links for the 14 inch bar or 55 drive links for the 16 inch bar. The 16 inch setup is the most common one in Australia.
Is the chain size the same on the MS 180 C-BE?
The letters on Stihl badges refer to versions of the saw rather than a different model family. Our fitment data covers the MS 180 itself, so for a C or C-BE don't assume — check the pitch, gauge and drive link count stamped on your bar, or send us a photo and we'll confirm it for you.
Will a Stihl MS 170 chain fit my MS 180?
On 16 inch bars, yes — the MS 170 and MS 180 both run 3/8" LP, .043" (1.1 mm), 55 drive links, so the chains swap straight over. The MS 170's 12 inch chain (44 drive links) won't fit the MS 180's 14 inch bar (50 drive links), though, so match the bar lengths first.
How many drive links does an MS 180 chain have?
50 on the 14 inch bar, 55 on the 16 inch bar. If you're not sure which bar you have, count the drive links on your old chain or check the number stamped on the bar.
Can I run a tungsten carbide chain on my MS 180?
The spec has to match the saw — 3/8" LP, .043" (1.1 mm), and your drive link count. Carbide-tipped chain holds its edge up to 10x longer than standard chain, which is a genuine upgrade if you're cutting dirty or seasoned hardwood. Check the GoldStrike tungsten carbide range for your size, and if it's not listed, get in touch and we'll sort you out.
TL;DR — Quick Reference
- MS 180 chain spec: 3/8" LP pitch, .043" (1.1 mm) gauge, low profile
- 14 inch bar = 50 drive links · 16 inch bar = 55 drive links (16" is the common one in Australia)
- Same 16 inch chain as the MS 170, MS 171 and MS 181
- Not the same as the MS 211 (.050"/1.3 mm gauge) or MS 230/MS 250 (.325" pitch, .063"/1.6 mm gauge)
- MS 180 C / C-BE badge? The bar stamp is the source of truth — or send us a photo
- Tungsten carbide tipped chain lasts up to 10x longer between sharpens
