DeWalt DCS391D2 20V MAX Circular Saw Kit - 6-1/ 2 Inch Blade and 55 mm Cutting Depth

DeWalt DCS391D2 20V MAX circular saw kit targets users who need a cordless 6-1/2 inch saw that still delivers a 55 mm cutting depth at 90 degrees on construction lumber. Built around DeWalt's 20V MAX battery platform, it packages the DCS391 saw with compact lithium-ion batteries, a charger, and a carry bag for jobsite portability.

Core Specs Of The DCS391D2 Kit

At the heart of the DCS391D2 kit is the DCS391 circular saw, which uses a 165 mm (6-1/2 inch) blade diameter and reaches a maximum cutting depth of 55 mm at 90 degrees and 42.1 mm at 45 degrees according to technical data on a European XR listing for the DCS391 series.Technical data for the DCS391NT saw give the same 55 mm and 42.1 mm depth figures, confirming the geometry used in DCS391D2 kits.

The same BayWa data sheet lists a no-load speed of 0-3,700 per minute, a 165 mm blade diameter, 50 degree bevel adjustment range, and a nominal 18 V XR lithium-ion battery system, matching the configuration DeWalt sells as 20V MAX in the US.The DCS391NT specification table shows a 55 mm cut depth at 90 degrees, 42.1 mm at 45 degrees, a 165 mm blade, and 18 V XR lithium-ion supply.

DeWalt's own documentation for the DCS391 saw explains that the 20V MAX label used in North America corresponds to a maximum initial battery voltage of 20 volts and a nominal voltage of 18 volts, aligning with the 18 V XR value on international manuals.A posted DCS391 circular saw manual notes 18 V nominal voltage, 165 mm blade diameter, and a 55 mm maximum cutting depth, reinforcing the crosswalk between XR and 20V MAX labeling.

Kit Contents And Battery Platform

In its DCS391D2 configuration, DeWalt positions the saw as part of a cordless circular saw kit that includes two compact XR batteries, a charger, and a carry bag alongside the tool and a carbide-tipped blade.An August 2026 product write-up on DCS391D2 names the kit contents as the DCS391 circular saw, two DCB183 2.0 Ah XR compact batteries, one charger, one carry bag, and a 24-tooth carbide blade.

The DCS391 manual lists compatible XR lithium-ion packs including DCB181, DCB182, DCB183, DCB183B, DCB184, DCB184B, DCB185, DCB187, DCB189, and several XR FLEXVOLT options, confirming that the DCS391D2 kit's DCB183 packs fit seamlessly into a broader 20V MAX ecosystem.The compatibility table in the manual lists DCB183 among the usable 18 V XR packs and notes that L2 and M2 kit models ship with two lithium-ion battery packs, a kit box, charger, and manual.

Within DeWalt's cordless line, the XR branding on the DCS391D2 kit indicates an emphasis on efficient motor design and battery runtime compared with older non-XR tools, while still relying on a brushed motor on this particular saw according to independent testing on a German comparison site.A DCS391 overview on WerkzeugMatrix describes the saw as part of the 18 V XR system, with a 165 mm blade, 55 mm depth at 90 degrees, and roughly 3.2 kg bare weight, positioning it as a powerful cordless option that remains compatible with the full XR battery family.

Price Positioning And Related Kits

While US-specific pricing for the DCS391D2 kit is less prominent than for some closely related bundles, a comparable configuration with a higher capacity battery pack gives a sense of where DeWalt places this saw within the cordless lineup.An early September 2026 pricing reference cites $247.12 for the DCS391P1 5.0 Ah kit in US retail as of 09/07/2026, indicating that DeWalt prices the DCS391 saw with battery and charger packages in the mid-tier range of cordless circular saw kits.

European price comparison entries show the DCS391 saw sold either as a bare tool or bundled with batteries and storage, often around the midrange price band for professional cordless circular saws.One Idealo summary of 18 V DeWalt circular saws lists the DCS391 with 460 watt output, 3.8 kg weight, a 165 mm blade, and 55 mm depth at 90 degrees, underscoring the saw's workhorse specification even when sold as a stand-alone tool.

A German retail listing for the DCS391NT version ties those specs to a package that includes a 24-tooth carbide blade and a T-STAK box, with batteries and charger sold separately.The DCS391NT package description mentions a T-STAK VI box, a 24 tooth HM blade, and the same 165 mm, 55 mm, and 42.1 mm figures, suggesting that DCS391-based kits like DCS391D2 share identical cutting hardware with regional differences primarily in enclosed batteries and storage.

How It Compares In The Cordless Saw Segment

Within DeWalt's cordless portfolio, the DCS391-based DCS391D2 kit sits below the most powerful XR and XR FLEXVOLT circular saws but above compact 4-1/2 inch cutters in terms of capability. The DCS391 saw's 165 mm blade and 55 mm cut depth at 90 degrees position it comfortably for one-pass cuts through standard 2x lumber, which is a key benchmark for workhorse framing saws.Independent scoring on WerkzeugMatrix calls the DCS391 the most powerful 18 V cordless hand-held circular saw in its specific comparison test, citing depth of 55 mm at 90 degrees and 42 mm at 45 degrees as key advantages within the XR lineup.

Compared with bare-tool options such as the DCS391NT, the DCS391D2 kit adds batteries and a charger in a way that targets users who may be starting or expanding a 20V MAX XR system rather than buying a single replacement saw.A product profile of DCS391D2 describes the kit as bundling the DCS391 saw with two DCB183 2.0 Ah batteries, a charger, and a carry bag, making it more of a ready-to-use system purchase than the NT bare-tool format.

DeWalt also offers higher-energy kits like the DCS391P2 bundle, which ships the DCS391 saw with two 5.0 Ah batteries according to a European retailer list.One ManoMano overview of DeWalt cordless circular saws references the DCS391P2 kit with two 5.0 Ah packs and a T-STAK box, hinting at a longer-runtime alternative to the compact-battery DCS391D2 configuration.

Use Case, Limits, And Placement

Framing carpenters, remodelers, and serious DIYers who already run DeWalt 20V MAX tools are the natural audience for the DCS391D2 circular saw kit, given its XR battery compatibility and cutting geometry suited to dimensional lumber and sheet goods. The combination of a 165 mm blade, 55 mm depth at 90 degrees, and 42.1 mm at 45 degrees makes it capable of cutting through standard framing stock, while the 50 degree bevel range offers enough angle flexibility for common roof and trim cuts.The bevel angle and depth figures position the saw solidly within the general-purpose circular saw class, though not as a replacement for larger-diameter, higher-power corded framing saws.

In terms of limitations, the DCS391D2 kit relies on compact 2.0 Ah batteries, which trade runtime for lighter weight and portability; users who demand extended cutting sessions on dense stock may gravitate toward kits with 5.0 Ah packs or XR FLEXVOLT saws that deliver more wattage and blade diameter.Comparative notes on DCS391D2 point out that the kit's documented speed of 3,700 per minute and power output of 460 watts sit slightly below the highest-output DCS391 variants, reinforcing its placement as a general-purpose workhorse rather than a top-tier performance saw.

Overall, DeWalt DCS391D2 serves as a practical 20V MAX XR circular saw kit centered on the proven DCS391 hardware, a 165 mm blade, and a 55 mm depth of cut at 90 degrees. Its mid-tier price positioning relative to beefier battery kits and FLEXVOLT models, combined with cross-compatibility across the XR system, makes it a straightforward choice for users who prioritize platform consistency and adequate cutting capacity over maximum runtime and power.
