The Milwaukee 6370-21 Corded 8" Metal Cutting Saw Kit is a corded metal cutting circular saw built for contractors who cut steel roofing, decking, framing members, plate, and other common jobsite metal. This is a metal cutting circular saw designed for fast, dry cutting of steel and other metal materials. Model Number: 6370-21. If you need cleaner cuts, less heat, and less time spent dealing with burrs and scorch marks, this saw is aimed right at that problem.

What makes this saw matter is how it cuts. Milwaukee's dry-cut approach shears the material instead of grinding through it like an abrasive wheel. In practical terms, that means cooler material after the cut, a virtually spark-free wake, and edges that are cleaner and more usable right away. On a metal job, that helps with handling speed, reduces cleanup, and cuts down on the extra finishing work that slows crews down.

The motor is rated at 15 amps with a 3,700 RPM no-load speed, which gives this corded circular saw the power needed for repeated metal cutting without waiting on batteries or dealing with power drop as the day goes on. Milwaukee also pairs that motor with premium cermet-tipped blades, which are designed to cut faster, stay sharp longer, and stand up better than typical abrasive wheels or basic carbide options. If cost per cut matters to your shop or crew, blade life is a real part of the value here.

Capacity is another big reason to look at this saw. With a 2-9/16 inch depth of cut at 90 degrees, it can make one-pass cuts through many common metal construction materials where smaller saws force you to flip the workpiece and cut again. That is a time saver on roofing and decking, and it is also safer and easier when handling larger sheets or awkward sections that are better left in place during the cut.

Milwaukee also put real thought into control and jobsite use. The saw includes a lower guard retraction lever for plunge cuts, which is especially useful for starting cuts in corrugated roofing and similar material. The lever sits adjacent to the side handle so the user can keep both hands on the tool while entering the cut. Add in the on-board sight line and blade point-of-entry indicators, and this saw gives the operator better visual control when accuracy matters.

Chip and spark management is another strength. The durable blade shield and integral ChipTank are there to deflect and collect hot chips and shavings instead of throwing them everywhere. That makes the work area easier to manage and helps reduce the usual mess that comes with metal cutting. The quick-release shield latch also speeds up waste disposal and blade changes, which matters when downtime adds up over a full day of cutting.

From a build and handling standpoint, this Milwaukee metal cutting saw is clearly meant for steady use, not occasional hobby duty. The rear and side handles use soft gripping surfaces, and the side handle is angled forward to reduce wrist strain while improving control in different cutting positions. The spindle lock also simplifies blade changes, and the grounded corded design with a 15 foot cord gives you familiar, predictable power on the job.

This saw makes the most sense for metal roofing contractors, steel framing crews, deck installers, general contractors, and fabrication users who want a dedicated metal cutting circular saw instead of forcing a standard saw into the job. If you regularly cut sheet metal, structural shapes, grating, or steel plate and want cleaner results with less rework, this is the kind of purpose-built tool that earns its space in the truck.

Milwaukee 6370-21 Corded 8" Metal Cutting Saw Kit Means Business

If you cut metal often enough to be annoyed by sparks, rough edges, and constant cleanup, this is the kind of dedicated saw that pays for itself in saved time.

• Who it's for: Roofing crews, deck installers, metal framing contractors, and fabrication users who need a purpose-built metal cutting circular saw for repeated steel cutting.
• Why it stands out: The cold-cut design, one-pass depth, chip containment, and plunge-cut capability solve real problems that generic circular saw setups do not.
• Worth knowing: This is a corded saw and it is not light, but that tradeoff buys you consistent output and the kind of capacity that makes sense for serious metal work.

• Is this a cordless or corded saw? It is a corded metal cutting circular saw powered by 120V AC.
• What blade size does it use? It uses an 8 inch blade with a 5/8 inch arbor.
• How deep will it cut at 90 degrees? The maximum depth of cut at 90 degrees is 2-9/16 inches.
• Does it have a spindle lock? Yes, the saw includes a spindle lock for blade changes.
