We remember when Milwaukee Tool showed us their M18 2782-20 metal-cutting circular saw. That cordless saw used a 5-7/8 in. blade and bragged about cutting over 500 pieces of 3/4-inch EMT on a single charge of its 5Ah battery pack. Fast forward to 2020 and we see the introduction of the first cordless 8-inch metal cutting circular saw. It not only delivers more capacity—but as a cold-cutting saw, it targets thick metal…with an appetite.

Corded Performance

According to the company, the brushless motor on the new Milwaukee M18 cordless metal circular saw delivers the performance of 15A corded metal cutting circular saws. They also tell us the 4,000RPM 2982-20 saw can work through a wide range of applications (like plate steel and corrugated decking) up to 30% faster than some competitive corded metal-cutting circular saws.

One of the major talking points of Milwaukee bringing this saw to the M18 cordless line revolves around its runtime. With the kitted 8.0 Ah battery, the M18 cordless metal circular saw cuts through 120 ft of corrugated decking on a single charge. Plus, should you run through the battery over the course of the day, the kitted rapid charger gets you back to a full charge in around an hour.

Milwaukee 2982-21 Features

The Milwaukee Cordless Metal Cutting Circular Saw comes with a variety of features that improve the user experience. It comes with overload protection in the form of an indicator light that alerts the user if he’s pushing the saw too hard. This also keeps you from overheating and over-discharge. A blade shield also protects you from a shower of hot sparks, collecting the metal chips as you cut. Users of the corded saw should find most of the blade and blade cover features very familiar.

The Milwaukee Cordless Metal Circular Saw has a blade cut capacity of 2-9/16″. It features an adjustable depth, electric blade brake, and dual-action trigger as an extra safety precaution.

Side By Side

As a point of comparison, we looked at the corded Milwaukee 6370 8″ Metal Cutting Saw which we reviewed several years ago. It has a 15A motor and 2-9/16 in. depth of cut. The blade speed tops out around 3700 RPM. The new 8-inch saw should prove capable of a similar performance to this corded model. As far as the stated 30% speed increase, we need to do some testing as some of that may include improvements to the blade as well as the power of the brushless motor to maintain cutting speed under load.

The Skilsaw Outlaw Metal Cutting Saw also makes for a good comparison. This 8-inch 15A saw uses a worm drive system with a blade speed of 3900 RPM. Seeing this type of cutting tool in a cordless form factor should grab the attention of metal fabricators everywhere.

We do love that Milwaukee kept the same excellent plunge lever that you can reach with your thumb. We wish all plunge saws worked this easily.

Sorry, but Makita has had a battery powered metal saw out for some time now.
