Milwaukee has officially announced their new M18 Fuel 12″ sliding miter saw, which they say generates the power of a 15A corded 12″ miter saw while being 15% lighter.
The new Milwaukee cordless miter saw is said to have the same cutting capacity as leading 12″ corded miter saws. It also features One-Key connectivity for tracking, inventory management, and securing against unauthorized use.
The new Milwaukee brushless miter saw can deliver up to 330 cuts per charge in 3-1/4″ base board. It can handle horizontal cutting of boards up to 2×14″, vertical cutting of up to 6-3/4″ trim, and nested crown molding up to 7-1/2″.
The new Milwaukee miter saw features a dual bevel design, adjustable stainless steel detent plate, and of course their Shadow Cut Line indicator which shines a light across the blade to produce a kerf-accurate cut line.
The new saw is ideally paired with the Milwaukee M18 12.0Ah HD battery, which is said to provide 50% more power and 33% longer runtime than their 9.0Ah HD battery, and while also running 50% cooler.

Discussion
We saw the new Milwaukee M18 Fuel 12″ sliding miter saw in action at their NPS19 new tool media event, and it cut smoothly.
I don’t think there’s much more to add. Milwaukee rounds out their cordless miter saw lineup with a new higher-powered 12″ sliding miter saw, and it’s ideally equipped with their HD12.0 battery. It’s a cordless 12″ sliding miter saw – one of very few on the market – and is said to have the power and capacity of a corded saw while being lighter.

I think it’s worth noting that the design much more resembles that of their 7-1/4″ sliding miter saw than their first 10″ miter saw.
Here’s a quick intro and demo video from NPS19:
