Can Milwaukee M18 Chain Saw 2727-21HD Replace Gas?

Launching very soon, July 2018, the Milwaukee M18 FUEL 16” Chain Saw 2727-21HD ($399) will be hitting the streets with the new 12.0Ah High Output batteries. The big question on everyone’s mind seems to be can this 18V cordless chain saw beat 36V, 40V, 54V, 60V, 80V but most importantly gas saws? Sure everyone would love to stop messing with gas engines and use a simple battery but a few important things have hindered them taking over the market. Most importantly Power, Price & Runtime! Milwaukee is not first to market here with a cordless chain saw that uses a tool battery but believe they can now address all 3 of these concerns.

Is 18V enough to Power a Chain Saw?

YES – from what we saw in the ash tree demo in the video above and in our hands-on this M18 FUEL 16” has a nice amount of power behind it. We’ve seen the comments that the gas saw had a worn out chain and other nefarious suggestions about this comparison, it does look like a Stihl ms170 or ms180 which would be roughly 32cc, not 40cc. Regardless just looking at the Milwaukee chain saw on its own it makes quick work of this ash log. It has solid power for cutting trees, timber frames, utility poles and about whatever else you might run into with a chain saw. The motor behind this saw delivers 2000+ watts of peak power, that’s 75% higher max power than 35cc Gas and 32% higher max power than 40cc Gas engines.

Chainsaw M18 vs Stihl

This is of course with the Milwaukee High Output 12.0Ah battery which will make a difference here. The new 21700 cells allow these batteries to pull more watts continuously without overheating. It’ll be a big question how much the power drops (or heavy use is limited) using the current M18 batteries with 18650 cells.

Is this a good value at $400?

Good for M18 Users – You got a very wide selection of top of the line gas chainsaws for less than $399, so alone just as a chainsaw not a super deal. This tool along with a handful of other new More Powerful M18 FUEL Tools will all be coming with the new 12.0Ah High Output battery, which the battery alone is $199. If you are an M18 user you are going to want to get a new 12.0Ah monster pack to use with your existing FUEL Sawzalls, circ saws, miter saws, Hole Hawgs, etc this is a great way to get both. When it comes to Outdoor Power Equipment it just seems to make much more sense to use battery packs that are compatible with hundreds of other tools instead of a dedicated system that just powers a string trimmer, blower and chainsaw.

How Much Runtime can a Battery Provide?

M18 Chain Saw Runtime

According to Milwaukee’s testing a single 12.0Ah battery has enough juice to cut an entire Cord of Fire Wood, 25 cuts through 10″ treated utility poles or 150 cuts in 6×6 cedar. That’s an impressive amount of runtime for a single 18V battery, of course the tool can run nearly indefinitely with a couple M18 batteries rotating on the charger. While all you exiting M18 batteries will work we are skeptical what sort of power loss there might be going back to your current 18650 cell M18 batteries with a power hungry tool like this. If you are going to do serious chain sawing you’re going to want more than 1 12.0Ah battery.

More Reasons Gas Power is a Dying Option

Of course there are all the other benefits, saving money on fuel, no worries about gas stabilizer, no engine failure from bad gas/mixing, no safety concerns about cans of gas sitting around or gas spills on other items, less maintenance, easier to start with 1 push, no emissions, safe to use indoors, less noise means safer for users, less disturbing to others, and the list goes on and on.
