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 want 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.Kit configuration and core specs put it in the workhorse segment of cordless circular saws.

Core Specs And Kit Contents

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.Documented cutting depth values confirm its ability to handle common framing cuts on 2x material in a single pass. The same listing notes a no-load speed of 3,700 per minute and a power output of 460 watts for the DCS391D2 configuration.Speed and power data for this kit position it slightly below the highest-output versions of the DCS391, but still within the range expected for a general-purpose cordless saw.

The saw itself is part of DeWalt's XR family and operates on 18V nominal voltage lithium-ion packs, sold in the US as 20V MAX batteries.DeWalt's US product page for the DCS391B saw explains that maximum initial battery voltage is 20 volts, with nominal voltage at 18 volts, which matches the XR labeling used on international manuals.Technical documentation for the DCS391 XR saw links the XR and 20V MAX platforms.

In the DCS391D2 bundle, the saw ships with two compact 2.0 Ah XR batteries labeled DCB183, a charger, and a fabric carry bag.Kit contents listing for DCS391D2 specifies that the kit includes two DCB183 2.0 Ah packs, one charger, and one carry bag alongside the saw and its 24-tooth carbide-tipped blade. With these batteries, the saw is geared toward lighter weight and quick charging rather than maximum runtime per charge.

Design, Handling And Safety Features

The DCS391 architecture used in the DCS391D2 kit emphasizes durability and accurate cutting, with an all-metal magnesium base and guard.Bare-tool description of DCS391 construction highlights the cast magnesium base and guard as key elements for repeatable cuts on MDF, plywood, and timber. The same UK listing reports a tool weight without battery of 3.2 kg and a product length of 360 mm, indicating a compact form factor and manageable mass for single-handed operation in many situations.Size and weight specifications for the DCS391 give a reference frame for handling.

DeWalt builds several control and safety features into the saw chassis. An electronic brake is included to stop the blade shortly after releasing the trigger, reducing the risk of damage or injury around the cut line.Feature list noting brake and lock-off switch also notes a lock-off switch to prevent accidental activation and a spindle lock to simplify blade changes. The bevel angle can be adjusted between 0 and 50 degrees with a tool-free mechanism, and the depth of cut scale is designed for easy readability when dialing in cut settings.Specification overview for the XR 165 mm saw describes bevel capacity and quick adjustment.

For users already invested in DeWalt cordless tools, the DCS391D2 kit slots into the broader XR and 20V MAX ecosystems. The XR manual lists compatibility with multiple battery packs including DCB181, DCB182, DCB183, DCB184, DCB185 and DCB546, covering capacities from 1.5 Ah up to higher-energy options used in demanding applications.Battery compatibility information for DCS391 XR confirms that higher-capacity packs can be paired with the saw to extend runtime beyond what the DCS391D2 kit batteries offer.

US Market Positioning And Price Context

While the DCS391D2 designation appears primarily on European retail pages, the underlying DCS391 saw and its 20V MAX configuration are widely sold in the United States as tool-only and kit versions. A US product page for the DCS391B tool-only model describes the saw as a 20V MAX 6-1/2 inch circular saw with battery and charger sold separately.US listing for the DCS391B saw situates it among DeWalt circular saws aimed at professional and serious DIY users.

For price comparison in the US, the DCS391 tool-only model is listed by Ace Hardware at a regular price of $129.00, with promotional pricing at $99.00 for the bare saw.Ace Hardware pricing for the bare DCS391-type saw places the tool-only version in the $99-$129 band common for 6-1/2 inch cordless saws. Kit configurations that include at least one 20V MAX battery and a charger run higher: a Home Depot listing for the DCS391P1 kit with a 5.0 Ah battery and charger shows a price of $247.12 for the saw, battery, and charger bundle.Home Depot price for DCS391P1 kit aligns with a mid-tier kit positioning.

The DCS391D2 kit, with two 2.0 Ah batteries, charger, and bag, appears on a UK retail page priced at £224.99 according to the listing.UK pricing information for the DCS391D2 kit underscores that this specific bundle is positioned as a fully equipped starter set in its home listing market, pairing the saw with two compact batteries instead of a single higher-capacity pack.

Comparison With Other DCS391 Kits And Alternatives

Compared with the DCS391M2 and DCS391P1 kits, which pair the saw with 4.0 Ah and 5.0 Ah batteries respectively, the DCS391D2 configuration trades maximum runtime for lower battery mass and the convenience of having two separate packs. The same UK retailer explicitly identifies the DCS391D2 as the 2.0 Ah battery version of the DCS391M2, which uses 4.0 Ah packs in its kit.Retail note comparing DCS391D2 and DCS391M2 makes clear that DCS391D2 is optimized around 2.0 Ah XR batteries.

From a US perspective, a bare DCS391-type saw priced at around $99.00 and a 5.0 Ah DCS391P1 kit priced around $247.12 define the ends of the typical range for this tool family.Price band for bare DCS391-type sawPrice band for DCS391P1 kit show how adding batteries and chargers shifts the price upward. DCS391D2, with two 2.0 Ah packs, would logically sit between those points in markets where it is sold, balancing total kit cost against the flexibility of carrying two lighter batteries.

Compared with alternative cordless circular saws of similar size, the DCS391 platform emphasizes a 50 degree bevel capacity and the ability to cut 2-1/4 inches deep at 90 degrees and 1-5/8 inches at 45 degrees on 6-1/2 inch blades as noted in a tool review.Independent review details on cutting depth and pricing places the bare tool in a $99-$149 price band and confirms that the saw retains enough depth to cut through standard 2x material at both 90 and 45 degrees with its stock blade.

Use Cases And Practical Assessment

In practical use, the DCS391D2 kit aligns most closely with the needs of trade carpenters, remodelers, and advanced DIY users who already operate within DeWalt's battery ecosystems and want a compact saw that still offers full-depth cuts on framing lumber. The XR platform compatibility list shows that users can swap in higher-capacity packs for extended cutting sessions, while keeping the kit's included 2.0 Ah batteries ready as lighter backups.Extended battery options for the DCS391 platform confirm that DCB184 and DCB185 packs can be used where more runtime is needed.

Limits show up primarily in runtime and weight trade-offs. The 2.0 Ah batteries supplied in DCS391D2 are well suited to shorter bursts of cutting and tasks like trimming plywood sheets or cutting dimensional lumber for small projects, but they do not match the endurance offered by 4.0 Ah and 5.0 Ah packs found in the DCS391M2 and DCS391P1 kits.Typical applications for the XR circular saw describe the saw as ideal for making quick smooth cuts in MDF, plywood, and timber up to 55 mm.

Overall, DCS391D2 can be understood as a kit-level adaptation of a widely sold US 20V MAX circular saw, tuned via its battery selection toward users who value portability and dual-pack flexibility over maximum runtime per charge. For US shoppers evaluating the broader DCS391 lineup, the concrete differences in battery capacity, kit contents, and price bands between DCS391D2, DCS391M2, and DCS391P1 provide the main basis for choice.
