Milwaukee M18 FUEL Metal Cutting Circular Saw Review – 2782-20

M18 Metal Circular Saw

The Milwaukee FUEL M18 5-3/8″ Metal Saw is a compact and lightweight metal cutting saw designed for electrical, mechanical, plumbing, HVAC and general construction contractors. The M18 saw, model number 2782-20, has a Brushless PowerState Motor for longer battery life and more power.  Milwaukee claims this saw will make over 370 cuts of 3/4″ EMT on a single battery charge, almost doubling the battery life of the prior model 2682-20.  Because of the saw’s lightweight, 6.5 lbs, it is easy to use for overhead cuts or full day work with less fatigue. To help cut thin metal that could have some vibration, Milwaukee added an extra-large cut guide to help keep the users line of cut in view.  There is also an impact resistant window with a LED light allowing excellent line of site for precise cuts, no matter the lighting.  The stainless steel shoe reduces chip build-up to prevent surface marring. The M18 Metal Saw comes with a  5-3/8″ 30T Carbide-Tipped Metal Saw Blade that makes cool, burr-free cuts through EMT, strut, threaded rod, sheet metal, angle iron and other ferrous materials.

Cool Cuts

This type of metal cutting, including much larger miter saws, are very popular for cutting metal in Europe.  Watching some of the very intricate and accurate cuts made by these cool cutting circular saws had me very interested in them.  Because our garage is used for storing cars and also metal work, we try to limit the amount of cutting that can put metal dust or fine particles in the air.  They can attract in areas of cars or car covers and scratch the car if they are moved or rubbed.  Metal circular saws create much larger chips that are easier to clean up and are not hot.  Immediately after your cut, the metal can be handled without worry of burning or cutting your hand from burrs.  The ability to cut metal in this manner makes this saw great for the construction trades.  Work can keep moving and be completed faster because there is no waiting over hot metal or deburring of edges.


Out of the few metal cutting saws that wehave used like this, Milwaukee has the lowest RPM.  This gearing of the motor seems to add more torque and is a great strategy for better cuts.  The lower RPM is that it allows for easier cuts over thin metal, like metal siding and roofing.  The cut speed seems to be about the same as higher RPM saws, but the saw and cut line are more controllable.  The blade used by Milwaukee could also have something to do with how well it cuts.  When doing a combination of wood and metal cutting, the saw was a bit slower, but still very accurate and controlled.  These saws are not designed to cut wood, but it is a benefit that it can easily cut sheathing if needed.


Milwaukee has a great design for a small metal saw that is light weight and has solid ergonomics to be used overhead if need be.  The LED light and clean sight of the cut line is excellent.  We enjoyed the saws smooth and vibration free feeling.  If you do a fair amount of metal cutting and have not used a saw like this we suggest you check them out.  Metal circular saws make less of a mess with little to no heat buildup.
