What this is
Two replacement chains in one of two common 16” sizes: 3/8” low-profile pitch, .043” gauge, 56 drive links (Oregon 90PX056G). It is the factory size on DeWalt’s 60V DCCS670 and DCCS690, Milwaukee’s M18 FUEL 2727-20, Makita’s XCU04 and XCU09, Toro’s 60V 51850 / 51851, several Greenworks 40V saws, Echo’s CCS-58V and the Harbor Freight Atlas 56938.
The two 16-inch sizes
Both common 16” chains have 3/8” low-profile pitch and 56 drive links. The gauge is what separates them:
| Gauge | Examples |
|---|---|
| .043” | DeWalt DCCS670, Milwaukee 2727-20, Makita XCU04, Toro 51850, EGO CS1600 — this chain |
| .050” | Husqvarna 135, Ryobi RY40550, Makita UC4051A, WEN 40417 — our .050” 16” chain |
The gauge is stamped on the tail of the bar. EGO owners: we also have a page written just for the EGO CS1600 and CS1610.
Fitting it
The DeWalt DCCS670 has a tool-free tensioning knob with a bar-adjust locking knob. On the Milwaukee 2727-20 you turn the tensioning screw with the adjustment tool, then tighten the bar nuts; Milwaukee asks for a low-kickback chain equivalent to the original or ANSI B175.1-certified.
