If you have made the switch to a battery-powered chainsaw like the Milwaukee M18 FUEL, you already know the benefits. There is no mixing two-stroke fuel, no pulling a starter cord until your shoulder aches, and no exhaust fumes filling up your shed or 4x4.
The Milwaukee M18 has become a favourite for Aussie campers, 4WD enthusiasts, and arborists because it is instant, powerful, and quiet. But to get the absolute best performance out of this machine—especially in Australian hardwood—you need the right setup at the business end of the saw.
Here is why upgrading to a Semi-Chisel chain and carrying a spare loop are the best moves you can make for your Milwaukee chainsaw.
1. Why Battery Saws Love Semi-Chisel Chains
Most chainsaws come out of the box with standard chains designed for speed in soft, clean timber. However, Australian conditions are different. We deal with dry, dusty hardwood like Red Gum and Ironbark, which can be tough on cutting edges.
For the Milwaukee M18, we highly recommend an Alpine Chain Co Semi-Chisel Chain.
-
Stays Sharper Longer: The "Semi-Chisel" profile has a slightly rounded working corner on the cutter tooth. This rounded edge is far more durable than the square corner of a full-chisel chain. It holds its edge significantly longer when cutting hard, dry, or dirty wood.
-
More Forgiving: If you are cutting firewood out bush, your wood is likely covered in dust, grit, or mud. Semi-chisel chains are more forgiving of these abrasive conditions, meaning you spend less time filing and more time cutting.
-
Smooth Efficiency: Semi-chisel chains typically feed smoother with less vibration. This smoothness helps maintain consistent RPMs, which is great for maximising the runtime of your M18 High Output batteries.
2. The Golden Rule: "Two is One, One is None"
Whether you are clearing a track on a 4WD trip or tidying up the backyard, nothing stops work faster than a rocked chain. Hitting a hidden nail in a fence post or grazing the dirt can dull a chain instantly.
Trying to hand-file a chain in the middle of a job (or in the rain) is frustrating. That is why professional arborists and experienced woodcutters always carry a spare chain loop.
-
Instant Swap: If you dull your chain, simply swap it for your sharp spare loop in under two minutes. You can get back to work immediately and sharpen the damaged chain later in the comfort of your workshop.
-
Pinch Insurance: If you get your bar pinched in a log (it happens to the best of us), having a spare chain allows you to remove the powerhead, fit the spare bar/chain combo if you have one, or simply gives you a backup if the original chain got damaged during the rescue.
3. Getting the Right Fit for Your Milwaukee
Milwaukee chainsaws use a specific "Narrow Kerf" system to reduce friction and extend battery life. It is critical to use a replacement chain that matches these specs perfectly to avoid damaging your sprocket or bar.
