Milwaukee sells several M18 chainsaws. In the UK it lists the M18 FCHS (40 cm), M18 FCHS35 (35 cm) and M18 FCHSC (30 cm), the M18 FTHCHS30 and FTHCHS35 top-handle saws, the twin-battery M18 F2CHS50 and the 20 cm M18 FHS20. In the US, its 16″ M18 FUEL chainsaw is the 2727-20. Milwaukee gives its own chain and bar part numbers and does not give an Oregon part code, so match the pitch, gauge and drive-link count it lists for your saw.

M18 FUEL 2727-20 Chainsaw — Chain Specifications
Milwaukee’s US 2727-20 is a 16″ M18 FUEL chainsaw that Milwaukee lists as running on one M18 battery. Its manual also lists a 14″ bar (49-16-2756) with a 52-link chain (49-16-2749).
Exact Chain Specification
| Specification | Value |
|---|---|
| Pitch | 3/8″ Low-Profile (LP) |
| Gauge | .043″ (1.1mm) |
| Drive Links | 56 (16″ bar) |
| Bar Length | 16″ (406.4 mm per Milwaukee’s manual) |
| Milwaukee chain / bar | 49-16-2715 / 48-09-3001 (A041 tail mount) |
Milwaukee gives 3/8″ LP, .043″ and 56 drive links for the 16″ 2727-20 bar. A chain with the same three figures matches that bar; we have not tested other brands on it.
Milwaukee Bar & Chain Part Numbers
Milwaukee lists replacement bar 48-09-3001 (16″, A041 tail mount, 56 drive links) and chain 49-16-2715 for the 2727-20, but no Oregon part code. Oregon’s 160SDEA041 is a 1.3 mm (.050″) bar, so it does not match the 2727-20’s .043″ chain.
Oregon Chains for Milwaukee M18 FUEL 2727-20
Oregon’s US part finder lists 90PX056G and R56 for the 2727-20. R56 is Oregon’s 90PX loop: 3/8″ LP, .043″, 56 drive links, for 16″ bars.
Oregon R56 (90PX)
Oregon lists R56 as an AdvanceCut 90PX chain for 16″ bars, and Oregon classes 90PX as low kickback.
Other Oregon Listings
In the US listing we checked, Oregon’s finder lists 90PX056G and R56 for the 2727-20. Oregon’s UK finder does not list the 2727; for the UK M18 FCHS (40 cm, 1.1 mm, 56 DL) Milwaukee does not name an Oregon chain.
Other Brands
Other makers sell 3/8″ LP .043″ chains in 56-link lengths. We have not tested them on Milwaukee saws; check the three figures in the table before buying.
Milwaukee vs Competition — Chainsaw Chain Specs Comparison
How does the M18 FUEL 2727-20 compare to DeWalt and Makita cordless chainsaws in terms of chain compatibility?
| Brand / Model | Bar Length | Pitch | Gauge | Drive Links | Chain Source |
|---|---|---|---|---|---|
| Milwaukee M18 FUEL 2727-20 | 16″ | 3/8″ LP | .043″ | 56 | Milwaukee 49-16-2715; Oregon’s US finder lists R56 |
| DeWalt DCCS670 | 16″ | Not stated by DEWALT | Not stated by DEWALT | — | Oregon’s US finder lists R56 (3/8″ LP .043″, 56 DL) |
| Makita DUC405Z | 16″ (40 cm) | 3/8″ LP | .043″ (1.1 mm) | 56 | Makita 196208-3 (EU parts list); Oregon R56 has the same spec |
Milwaukee and Makita publish 3/8″ LP, .043″ and 56 drive links for these 16″ saws; DEWALT’s page does not state them, and Oregon lists R56 (same spec) for both the 2727-20 and the DCCS670. Each maker sells replacement chains under its own part numbers.
Replacement Chain Options for M18 FUEL
Your main options:
Option 1: Milwaukee’s Own Chains
Milwaukee lists chain 49-16-2715 for the 16″ 2727-20 (US) and chain 4932464873 for the 40 cm M18 FCHS (UK).
Option 2: Oregon Direct
Oregon’s US part finder lists R56 / 90PX056G for the 2727-20.
Option 3: Other Brands
Check the pitch, gauge and drive-link count against the table; we have not tested other brands on Milwaukee saws.
Option 4: Unbranded Chains
Unbranded chains are sold with the same three figures; we have not tested them.
Whichever you choose, match 3/8″ LP, .043″ and the drive-link count for your bar.
M18 FUEL 3004-20 (8″) — Separate Chain
Milwaukee’s 3004-20 (M18 FHS20 in the UK) uses a 20 cm (8″) bar with 3/8″ LP, .043″ chain and 33 drive links (US chain 49-16-2750, bar 49-16-2751; UK chain 4932480176, bar 4932480169), and Milwaukee lists one M18 battery for it.
Its chain does not fit the 16″ saw because the drive-link count is different. Use the 33-link chain Milwaukee lists, or another chain with the same pitch, gauge and drive-link count.

How we compile this guide
We cross-reference compatibility details against manufacturer specifications where available, official tool manuals, and the physical standards that govern fitment (bore sizes, arbor diameters, voltage platforms, connector types). We prioritise primary sources over retailer listings, flag anything we can’t confirm, and re-verify the data on a regular cycle. Where we give a buying recommendation, we tell you the reasoning — not just the link. More on our method →
