DEWALT’s cordless chainsaws in our sources are the US 20V MAX DCCS620 (12″) and 60V MAX FLEXVOLT DCCS670 (16″), and the UK 18V XR DCM565 (30 cm) and 54V XR FLEXVOLT DCMCS574 (45 cm), DCMCS575 (50 cm) and DCMCST635 top-handle (35 cm). Chain part numbers change with bar length and market, so match the chain to your bar.

Pitch, gauge & drive-link count decoded — match any chain yourself.
DEWALT does not use one chain across its range — the part number changes with bar length and market. In the US, 12″ bars take DWO1DT612 and 16″ bars DWO1DT616T (both 3/8″ LP .043″; DEWALT does not state the drive-link count). In the UK, the 30 cm chain is DT20676-QZ (3/8″, 1.1 mm, 45 drive links). We did not find DT20700 on DEWALT’s UK or Australian sites.
DeWalt 20V MAX vs 60V MAX FLEXVOLT Chainsaw Chains
DEWALT’s saw pages and manuals mostly give bar lengths and part numbers rather than pitch, gauge or drive links, so the figures below come from DEWALT’s chain and bar pages and, where stated, Oregon’s part finder.
20V MAX Compact (DCCS620)
12″ bar. The DCCS620 manual lists service bar N594322 and chain N580237. DEWALT’s 12″ chain DWO1DT612 is 3/8″ LP .043″; DEWALT does not state its drive-link count. Oregon’s US part finder lists R45 (90PX, 45 drive links) for the DCCS620. We have not tested runtime.
60V MAX FLEXVOLT (DCCS670, DCCS690)
16″ bar (18″ optional). The DCCS670 manual lists service chains N594321 (16″) and N594318 (18″). DEWALT names its 16″ replacement chain DWO1DT616T (3/8″ LP .043″, drive links not stated). Oregon lists R56 (90PX, 56 drive links) for the DCCS670. We have not tested runtime or cutting capacity.
We did not find a DEWALT page or manual for the DCCS690 or DCCS690M1. Oregon’s R56 page lists the DCCS690 and DCC690M1 among the saws R56 fits.
UK-Market Models (DCM565, DCMCS575)
The DCM565 has a 30 cm bar, and its manual lists the same service bar and chain numbers as the DCCS620 (N594322 / N580237). DEWALT UK sells a 30 cm chain, DT20676-QZ (3/8″, 1.1 mm, 45 drive links), but its page does not name the saw. The DCMCS574 has a 45 cm bar (DT20687 bar and chain set) and the DCMCS575 a 50 cm bar; DEWALT does not give pitch, gauge or drive links for either on the pages we hold.
DeWalt OEM chain part numbers
DEWALT gives different chain part numbers by bar length and market: DWO1DT612 for 12″ bars and DWO1DT616T for 16″ bars in the US, and DT20676-QZ for 30 cm bars in the UK. For the UK DCMCS574 DEWALT sells the DT20687 bar and chain set, and for the DCMCST635 top-handle saw the DT20692 chain (.325″ LP).
We hold no published DEWALT warranty term for replacement chains and no price comparison with other brands.
DeWalt Chains for 12″ and 30 cm Bars
For the DCCS620, DEWALT’s 12″ chain is DWO1DT612. The UK DCM565 manual gives the same service chain number (N580237) as the DCCS620; DEWALT UK’s 30 cm chain DT20676-QZ has 45 drive links, but its page does not name the saw. Oregon lists R45 (45 drive links) for the DCCS620.
DeWalt Chains for 16″ Bars
For the DCCS670, DEWALT’s 16″ chain is DWO1DT616T (service chain N594321; N594318 for the optional 18″ bar). Oregon lists R56 (56 drive links) for the DCCS670. The UK DCMCS575 has a 50 cm bar, so a 16″ chain does not fit it, and we did not find a DEWALT chain part for it.
Oregon Cross-Reference for DeWalt Chainsaws
Oregon’s US part finder lists R45 (90PX045G) for the DCCS620 and R56 for the DCCS670. We did not find the DCCS or DCM models in Oregon’s UK finder.
| Bar Length | Drive Links | DeWalt OEM | Oregon Equivalent |
|---|---|---|---|
| 12″ (DCCS620) | 45 (Oregon R45) | DWO1DT612 (US) | Oregon R45 (90PX045G) |
| 16″ (DCCS670) | 56 (Oregon R56) | DWO1DT616T (US) | Oregon R56 |
Oregon lists R45 and R56 as 90PX chains (3/8″ LP, .043″), which Oregon classes as low kickback.

OEM vs Aftermarket Chains for DeWalt Chainsaws
When your chain dulls or breaks, you have three main replacement options:
Option 1: the OEM DeWalt chain
From DEWALT dealers and online retailers, by DEWALT’s part number for your bar (see above).
Option 2: Oregon and Other Brands
Oregon lists R45 and R56 for the DCCS620 and DCCS670. We have not tested other brands on DEWALT saws; check the pitch, gauge and drive links before buying.
Option 3: Budget Aftermarket (Generic or Amazon Own-Label)
Unbranded chains are sold in the same sizes; we have not tested them.
Whichever you choose, match the pitch, gauge and drive-link count to your bar.

Frequently Asked Questions
What chainsaw chain does a DeWalt DCCS620 use?
DEWALT’s 12″ chain for the DCCS620 is DWO1DT612 (3/8″ LP, .043″); DEWALT does not state its drive-link count. Oregon’s US part finder lists R45 (45 drive links) for the DCCS620.
Is one DeWalt chain compatible with all DeWalt chainsaws?
No. DEWALT uses a different chain for each bar length (DWO1DT612 for 12″, DWO1DT616T for 16″, DT20676-QZ for UK 30 cm bars), and the DCMCST635 top-handle saw uses .325″ LP chain.
Can I use an Oregon chain on my DeWalt DCCS670?
Yes. Oregon’s US part finder lists R56 (3/8″ LP, .043″, 56 drive links) for the DCCS670.
What’s the difference between the DCCS620 and DCM565?
They are sold in different markets: the DCCS620 (US, 20V MAX, 12″ bar) and the DCM565 (UK, 18V XR, 30 cm bar). Their manuals list the same service bar and chain numbers (N594322 / N580237). We have not confirmed that they are otherwise identical.
Are DeWalt and Makita chainsaw chains interchangeable?
Not directly. Makita’s DUC saws and DEWALT’s 12″ and 16″ chains are all 3/8″ LP .043″, but the drive-link count must also match your bar (for example 40 on a Makita 25 cm bar, 45 on Oregon’s 12″ R45 and 56 on a 16″ bar).
How often should I replace my DeWalt chainsaw chain?
We have not tested chain life. Replace a chain that will not hold an edge or has damaged teeth.
Can I sharpen a DeWalt chain instead of replacing it?
Yes. Use the file size given in your saw’s manual or on the chain packaging, or take it to a dealer for sharpening.
What is 3/8 LP vs 3/8 full-pitch chainsaw chain?
They are different chain types. DEWALT’s 12″ and 16″ replacement chains are 3/8″ LP. Oregon’s guidance is 3/8″ low profile for smaller saws and standard 3/8″ for larger petrol saws, and the chain pitch must match the drive sprocket and bar nose sprocket. Order the type your bar or manual lists.
Is the DeWalt 60V MAX DCCS670 any good?
We have not tested it. For the batteries behind rival saws, see our Makita 36V and Milwaukee M18 pages. For detailed brand comparisons and battery compatibility, visit our chainsaw compatibility hub.
Can I use the DeWalt 20V battery on the 60V DCCS670?
DEWALT lists the DCCS670 as a 60V MAX FLEXVOLT saw. A 20V MAX battery is a different platform, so check DEWALT’s page or manual for the battery packs it approves for the saw.
Where can I find my DeWalt chainsaw’s exact bar length?
Check the user manual (from the box or DEWALT’s website) or the label on the saw. DEWALT’s manuals list the service part numbers for the bar and chain.

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 →
