Best replacement chainsaw chains for DeWalt
Researched by Deal.ai's shopping agent across stores on November 4, 2026. Prices below are today's.
Top pick: DeWalt DWO1DT612 12-inch chain. It's the genuine DeWalt replacement, and its specs match the 20V MAX saw exactly — 3/8" low-profile pitch, .043" gauge, 45 drive links — so it drops straight onto the stock bar with no guesswork. Buy two: a spare means you swap and keep cutting instead of stopping to sharpen.
Who the others suit:
- DeWalt 20V MAX 12-inch replacement chain — the same fit with the most store options if the DWO1DT612 is out of stock.
- Proven Part 12-inch (3/8" LP, 45 DL, Oregon 90PX045G match) — the budget route for anyone who treats chains as consumables and resharpens or replaces often.
- 90586162 chain for DCCS620B — a direct-fit aftermarket option if you want a single-source spare.
- DeWalt 16-inch chain (3/8" LP, .043", 56 DL) — only if you've swapped to the 16-inch bar; it won't fit the 12-inch saw.
Skip anything listed as 8-inch or with a .050" gauge — wrong size for this saw.
