Overview
This 2-pack of aftermarket 18-inch replacement chains is designed to fit select Worx chainsaw models. It serves as a drop-in replacement when the original chain becomes dull past the point of resharpening, develops a damaged cutter, or has stretched beyond the tensioner’s adjustment range. Having a spare on the shelf eliminates trips to the dealer mid-project.
Key specifications
- Bar length: 18”
- Pitch: 3/8
- Gauge: .050”
- Drive links: 63DL
- Quantity: 2-pack
- Type: Semi-chisel (aftermarket replacement)
Compatibility
Engineered to match the specifications of select Worx chainsaw models, this chain drops in without modification. Before ordering, verify the three critical numbers — pitch, gauge, and drive-link count — against the stamp on your guide bar. A mismatch in any one dimension means the chain won’t fit safely.
Installation notes
Power down the saw and remove the battery or disconnect it from power before servicing. Remove the side cover or bar-cover plate to expose the bar and sprocket. Slide the worn chain off the bar groove and sprocket, noting the direction of the cutters. Install the new chain with cutting teeth facing forward on top of the bar. Reattach the cover and adjust chain tension — the chain should pull slightly away from the bar rail and snap back without sagging.
Common questions
Q: Will this 2-pack 18” chain fit my WORX WG304.2, and does it match the original chain specs?
Yes. This chain is made for WORX WG304.2, WG304.1, WG304, and WG300 18-inch electric chainsaws that use a 3/8” pitch, .050” gauge, and 63 drive links. As long as your saw and bar match those specs, it should install and tension like the original.
Q: How do I confirm this is the right chain if my bar says 18” but I’m not sure about the rest of the specs?
Bar length alone is not enough, so check that your current chain is 3/8” pitch, .050” gauge, and 63 drive links. If your WORX model is one of the listed WG304-series or WG300 saws and it uses those exact measurements, this is the correct replacement chain.
Q: Any tips for installing and maintaining this chain on a WORX WG304.1?
When installing, make sure the cutter teeth on the top of the bar face forward, then set chain tension so the chain snaps back into the bar groove but still pulls around by hand. For longer chain life, keep the bar groove clean, maintain proper oil flow, and recheck tension after the first few cuts since a new chain can stretch slightly.
