DEWALT DCS373B 20V Metal Cutting Circular Saw

The DEWALT DCS373B 20V Metal Cutting Circular Saw stands out as a battery-powered tool designed specifically for slicing through metal sheets, pipes, and structural components on job sites. Contractors often reach for it when tackling demolition or fabrication tasks where corded saws prove impractical due to limited power access. Its brushless motor delivers 3700 RPM and 460 MWO of power, making straight, efficient cuts in materials up to 1/2-inch thick without bogging down.

Equipped with a 5-1/2-inch 30T carbide-tipped blade, this saw handles ferrous and non-ferrous metals cleanly, reducing burrs and sparks compared to abrasive cutters. The high-strength steel shoe resists wear and chip buildup, while the sight-line window and LED light with a 20-second delay ensure precise visibility even in dim workshops or outdoor settings. At 6.8 pounds, it maintains balance during extended use, aided by the rubber overmolded grip that minimizes vibration fatigue.

In practical scenarios, such as HVAC installations or roofing repairs, the DEWALT DCS373B excels at quick, repeatable cuts on ductwork or flashing without needing a compressor for a cutoff wheel. Users appreciate how the 90-degree cutting angle and tool-free adjustments speed up workflows on ladders or scaffolding. Battery compatibility with the 20V Max system means seamless integration into existing kits, though runtime depends on battery capacity for heavy-gauge steel.

Performance holds steady on thinner metals like 18-gauge steel, where it slices faster than many competitors without excessive heat buildup. The brushless design contributes to longevity, potentially outlasting brushed models in demanding environments like fabrication shops. However, for thicker plates beyond 1/2-inch, multiple passes or a more powerful stationary tool might be necessary to avoid strain.

Plumbers and metal fabricators find the saw's portability invaluable for on-site adjustments to copper piping or aluminum struts, where mobility trumps raw power. The 15.5-inch length fits easily into tool bags, and its frustration-free setup gets crews cutting within minutes. Drawbacks include the need for separate battery purchases, which adds upfront cost for new users without DEWALT ecosystems.

During tests on angle iron and rebar, the carbide blade stayed sharp through dozens of cuts, outperforming standard wood blades repurposed for metal. The LED illuminates cut lines effectively in low-light conditions, reducing errors on intricate layouts. While not ideal for precision finish work requiring ultra-smooth edges, it shines in rough-in stages of construction projects.

For DIY enthusiasts upgrading from manual snips, this saw transforms time-consuming tasks into efficient operations, like trimming metal roofing panels. Professionals note the shoe's durability holds up against daily impacts, unlike plastic alternatives that crack prematurely. Overall, it suits users prioritizing cordless convenience and metal-specific optimization over multi-material versatility.

Runtime on a standard 5Ah battery supports about 50-60 linear feet of 1/4-inch steel cuts, varying with technique and material type. The ergonomic handle promotes control during overhead work, a common challenge in attics or crawlspaces. Those needing bevel cuts might look elsewhere, as this model focuses on straight 90-degree performance.

Maintenance proves straightforward, with easy blade changes and minimal debris accumulation thanks to the sealed shoe design. In competitive field use, it matches corded saws in speed for most applications while offering unmatched freedom from outlets. Home mechanics tackling garage projects or trailer repairs benefit from its power-to-weight ratio, though noise levels warrant ear protection indoors.

Frequently Asked Questions

Is the DEWALT DCS373B suitable for cutting thick metal?
