This 16-inch chainsaw chain is the perfect replacement for your Milwaukee 2727-20 and 2727-21HD M18 FUEL 16-inch chainsaws.

Replacement chain fitment for Milwaukee 2727-20 and 2727-21HD

This 16-inch replacement chainsaw chain is made for the Milwaukee 2727-20 and 2727-21HD M18 FUEL 16-inch chainsaws. If you need a fresh chain for smoother cuts and dependable performance, this is the matching replacement identified by Milwaukee part number 49-16-2715.

A worn chain can make even a strong saw cut slowly, pull to one side, or throw fine dust instead of chips. Replacing it with the correct chain helps restore clean cutting and keeps your saw working the way it should.

Will this chain fit your saw?

This chain is intended for the following Milwaukee models:

• Milwaukee 2727-20
• Milwaukee 2727-21HD

It is also identified by Milwaukee replacement chain part number:

• 49-16-2715

The most important fitment point is that your saw is the Milwaukee M18 FUEL 16-inch platform listed above. Since chainsaw chains must match the bar and drive system exactly, it is always smart to confirm the chain details printed on your current bar or in your saw documentation before ordering.

When checking fitment, verify these four chain specs:

• Bar length: 16 inches
• Pitch: match the pitch marked for your saw/bar
• Gauge: match the gauge required by the bar groove
• Drive-link count: match the exact number required by the bar

Even if two chains are both called “16-inch,” they are not automatically interchangeable. A chain can only fit correctly when the pitch, gauge, and drive-link count all match the bar and sprocket setup. If your current chain or guide bar markings match the specifications required for the Milwaukee 2727-20 or 2727-21HD with replacement part 49-16-2715, this is the correct fit.

A quick way to confirm is to look at:

• The model number tag on the saw body
• Any markings stamped or printed on the guide bar
• The packaging or markings on your old chain, if still readable
• Your owner’s manual for the chain specification tied to part number 49-16-2715

Replacing the chain

Replacing the chain is straightforward, but do it carefully.

1. Remove the battery from your Milwaukee chainsaw before doing any service.
2. Loosen the side cover and back off the chain tension so the old chain can be removed from the bar and drive sprocket.
3. Install the new chain around the drive sprocket and along the guide bar, making sure the cutter direction matches the normal forward cutting direction on the top of the bar.
4. Reinstall the side cover and adjust chain tension until the chain sits snugly on the bar but can still be pulled around by hand with a gloved hand.
5. Double-check that the chain is seated properly in the bar groove and around the sprocket before tightening everything fully.
6. Reinstall the battery and test at low effort first, then recheck chain tension after the chain has run briefly.

A new chain can stretch slightly during initial use, so it is normal to check and retension it again after the first few cuts.

Keeping it sharp

A sharp chain cuts faster, safer, and with less strain on the saw.

• Avoid contacting dirt, rocks, metal, or the ground, since even brief contact can dull cutters quickly.
• Keep proper chain tension. A chain that is too loose or too tight can wear faster and cut poorly.
• If cutting performance drops and the saw starts producing fine sawdust instead of larger chips, it may be time to sharpen or replace the chain.

It also helps to inspect the bar regularly for wear and keep the saw clean so the chain can run smoothly.

FAQ

Will this chain fit every Milwaukee 16-inch chainsaw?
No. This replacement is specifically listed for the Milwaukee 2727-20 and 2727-21HD M18 FUEL 16-inch chainsaws. Always confirm your exact model and chain/bar specs.

How do I know if my chain needs replacement instead of sharpening?
If the chain is badly worn, damaged, missing teeth, or no longer holds an edge well, replacement is usually the better option. If it is only mildly dull, sharpening may restore performance.
