DeWalt DCS391D2 20V MAX Circular Saw Kit - 165 mm Blade And 3,700 RPM Cutting Power

DeWalt DCS391D2 20V MAX circular saw kit packages the DCS391 cordless saw with compact XR lithium-ion batteries, a charger and a carry bag for jobsite wood cutting without a cord. Built around a 165 mm carbide blade and a documented 3,700 RPM no-load speed, it is configured to deliver up to 55 mm cutting depth at 90 degrees on dimensional lumber according to technical listings for the DCS391D2 kit.DCS391D2 kit specifications

Core Specs And Kit Configuration

At the heart of the DCS391D2 bundle is the DCS391 circular saw, part of DeWalt's 20V MAX XR cordless platform, which uses a 165 mm (6-1/2 inch) blade and reaches a maximum cutting depth of 55 mm at 90 degrees and 42.1 mm at 45 degrees in the B&Q specification sheet.Depth of cut details The same listing documents a 50 degree bevel capacity, a 3,700 per minute no-load speed and a 460-watt power output for this configuration.Power output and speed

The DCS391D2 kit contents are listed as the DCS391 saw, two DCB183 2.0 Ah XR lithium-ion batteries, one charger and one fabric carry bag alongside the preinstalled 24-tooth carbide-tipped blade, which is intended for general wood cutting.Kit contents listing Technical documentation for the DCS391 XR saw confirms that the saw operates on an 18V nominal XR Li-ion battery pack and lists compatible battery packs including DCB183, which matches the compact 2.0 Ah batteries packaged in the DCS391D2 bundle.DCS391 technical data

Motor, Platform And Cutting Performance

DeWalt positions the DCS391 saw as a 20V MAX cordless sidewinder with a powerful fan-cooled motor; the US product page for the DCS391B tool-only version specifies a 5,150 RPM motor driving the same 6-1/2 inch blade, which represents the higher-output configuration within the family.DCS391B manufacturer specs In contrast, the DCS391D2 kit specification from B&Q documents a 3,700 per minute no-load speed and 460-watt power output, placing this kit slightly below the highest-output 20V MAX configuration but still in the general-purpose cordless circular saw segment.Speed comparison within DCS391 range

Independent testing and reviews of the DCS391 saw in the US confirm that a 6-1/2 inch blade and a 3,700 RPM no-load speed are sufficient to cut through common 2x lumber at both 90 and 45 degrees, and note that the saw uses a bevel capacity of up to 50 degrees for angled cuts.DCS391 circular saw review The Home Depot listing for another DCS391-based kit in the US market likewise highlights a 20-volt motor delivering up to 5,150 RPM, up to 50 degree bevel cut capacity and a design focused on cordless framing cuts with multiple battery options, which places the DCS391D2 kit logically in the same workhorse category even though its documented speed is lower.US DCS391 kit positioning

Direct From DeWalt

The DCS391D2 kit itself does not have a dedicated US manufacturer page, but DeWalt's DCS391B product page provides the core saw specifications that underpin this bundle, including blade size, maximum RPM and bevel capacity.DCS391B saw details Users considering the DCS391D2 kit in the US are effectively getting the same DCS391 saw platform with different battery and charger configurations built around the 20V MAX system.

Comparison With Other 20V MAX Circular Saw Kits

Compared with DeWalt's US DCS391 kits that pair the saw with higher-capacity 4.0 Ah or 6.0 Ah batteries, the DCS391D2 bundle documented by B&Q uses two compact DCB183 2.0 Ah XR packs, prioritizing lower tool-and-battery weight over maximum runtime.Compact battery configuration The Home Depot DCS391BWCB2460C kit, by contrast, combines the same saw platform with one 20V 6.0 Ah battery and one 20V 4.0 Ah battery, driving price and runtime higher than what would be expected for a compact 2.0 Ah-based bundle.Higher-capacity battery kit

In terms of cutting capacity, both configurations share the same 6-1/2 inch blade diameter and the ability to cut through 2-1/4 inch material at 90 degrees and 1-5/8 inch material at 45 degrees in US measurements, which corresponds closely to the 55 mm and 42.1 mm depths documented for the DCS391D2 kit.US depth-of-cut values For buyers comparing kits, the practical difference lies primarily in battery capacity and price rather than in the fundamental saw capabilities, with the DCS391D2 configuration targeting users who prefer a lighter kit with enough runtime for intermittent framing work.

Brand, Manufacturer And Positioning

DeWalt, the trade brand on the DCS391D2 circular saw kit, is part of the DeWalt Industrial Tool Company, which operates as a division of Black & Decker and belongs to the Stanley Black & Decker group at the parent level.DeWalt corporate background Historical brand overviews and ownership summaries describe DeWalt as a flagship professional tools brand wholly owned by Stanley Black & Decker and repositioned as the company's primary professional tools platform after its acquisition in 1960 and the later merger that created Stanley Black & Decker.Ownership overview

In the US, DeWalt product documentation identifies "DEWALT, a division of Black & Decker (U.S.) Inc., 701 E. Joppa Road, Towson, Maryland" as the responsible entity on labels and manuals, situating the DCS391 saw and its related kits within the US arm of the group.US DeWalt corporate identity That positioning aligns the DCS391D2 kit with DeWalt's broader 20V MAX cordless platform aimed at professional contractors and serious DIYers who require cross-compatibility between tools and batteries across multiple jobsite applications.

Use Case And Verdict

Within the landscape of cordless circular saws, DeWalt DCS391D2 20V MAX circular saw kit sits as a workhorse option that pairs a full-size 165 mm blade and 55 mm cutting depth with compact 2.0 Ah batteries and a 50 degree bevel range. The technical data and US reviews of the underlying DCS391 saw confirm that this platform is capable of cutting common 2x lumber and performing framing and general construction cuts while remaining relatively lightweight compared with higher-capacity battery bundles.Practical use case assessment

For US users choosing between kits, the DCS391D2 configuration is best suited to tradespeople and DIY users who already own other 20V MAX tools or who value portability, a 6-1/2 inch blade and a documented 55 mm cutting depth over maximum runtime. Those who need extended cutting sessions or heavier-duty battery capacity may look to US kits that bundle the same saw with 4.0 Ah or 5.0 Ah batteries, but the underlying cutting geometry and bevel capacity remain constant, making the DCS391D2 kit a straightforward way to access DeWalt's 20V MAX circular saw platform with a lighter battery setup.
