DEWALT 20V MAX Cordless Jig Saw Tool Only (DCS331B) review

This is a document-based assessment, not a hands-on test. The DEWALT DCS331B is a 20V MAX cordless, top-handle jigsaw listed on DEWALT’s US site. Its useful combination is a T-shank clamp, variable-speed trigger, four cut-action positions, an adjustable blower and a bevel shoe. The package warning matters: the B suffix is the tool-only configuration, so the battery and charger are sold separately.

Start with the exact package, not the model family

DEWALT’s US DCS331B page says “Tool Only” and identifies one DCS331 20V MAX saw and two blades in the included-items list. It also says the battery and charger are separate. That means the B package is not an out-of-box power kit even though it includes blades. If a listing mentions a battery, charger or bag, check whether it is the DCS331M1 kit rather than the DCS331B bare tool, and confirm the exact seller’s inventory.

The related DCS331M1 page names the same DCS331 saw, but lists a DCB204 4.0Ah battery, charger, one blade and kit bag. The package images show the distinction clearly: the bare-tool image depicts the saw, while the M1 image depicts a battery, charger and bag with it. The two suffixes are not two different saw mechanisms in the checked product pages; they are a saw package and a kit package. The M1’s included 4.0Ah battery does not establish a particular runtime, and the pages provide no basis for a price or current-stock comparison.

Trigger speed and orbital action do different jobs

DEWALT rates the DCS331 at up to 3,000 strokes per minute and describes a variable-speed trigger. The linked DCS331 manual identifies a trigger switch and a trigger lock button; it does not describe the separate speed dial found on some other DEWALT jigsaws. Trigger pressure changes stroke rate below the tool’s maximum, so the control is not a fixed-speed dial. The cited page and manual do not establish a numeric stroke length or an official cutting-depth figure.

The shoe-side lever selects four actions: position 0 is straight cutting, while positions 1, 2 and 3 add progressively more orbital motion. The manual explains that the orbital stroke moves the blade forward as it cuts. That can make a cut faster and more aggressive, but the tradeoff is a less smooth edge. It is a choice of stroke pattern, not a promise that the saw will cut a curve cleanly or that a specific blade will suit every material.

The manual is explicit about a boundary that should survive any buying summary: do not cut metal or hardwood with orbital action. Its advice for softwood or plastic is a starting point, not a substitute for a work-appropriate blade or a supported workpiece. If the material is unknown, keep the selector on straight action until its properties are clear. The matcher therefore treats broad “wood” as straight-only and reserves the orbital setup for the public Softwood (not hardwood) or Plastic choices.

T-shank fit, shoe adjustment, and surface protection

The DCS331B product page says the lever-action keyless clamp accepts T-shank jigsaw blades. This is stronger evidence than a retailer’s generic compatibility label: a buyer who already owns T-shank blades has a documented interface match, while a U-shank-only blade supply is not a match. DEWALT lists two blades with the bare tool and one with the M1 kit, but the pages do not establish that those included blades cover every material or finish in the manual. Check each blade’s own rating and teeth before using it.

The US product page gives shoe-bevel detents at 0, 15, 30 and 45 degrees. The manual describes the shoe as tilting left or right and discusses the 15-, 30- and 45-degree detents. For an angled cut, verify that the shoe is locked after adjustment and that the actual angle suits the work; a stated detent is not a measured guarantee of angle after wear or setup.

A removable shoe cover is described as helping protect the work surface from scratches. It is a protection feature, not a no-mark guarantee on delicate veneer, laminate or finished stock. Support the work, use a blade made for the desired cut, and test the complete arrangement on scrap if appearance matters. The cited DCS331 sources do not establish an anti-splinter insert or a separate external vacuum-extraction kit, so those should not be assumed from the blower feature.

The blower clears a view; it is not dust capture

DEWALT describes an adjustable dust blower that moves chips away from the cut line. That helps explain what the feature is for, but a blower is not a vacuum extractor and does not capture fine dust. The reviewed US page and manual do not establish an external vacuum connection for this configuration. If dust extraction is essential, verify the accessory and exact saw compatibility in current DEWALT documentation before buying; do not convert a “dust blower” label into a claim of collection.

The page lists no LED work light, and the sources checked here do not characterize the motor as brushed or brushless. Those gaps are intentional in this assessment: the DCS334B sibling is explicitly advertised as brushless and uses a variable-speed trigger plus dial, while the DCS331B page specifies a trigger and a 3,000-SPM maximum. The DCS334B’s motor, dial, light or other features should not be carried across to the DCS331B just because both run on DEWALT 20V MAX batteries.

Who should shortlist it—and what to check first

The DCS331B suits a buyer who wants a cordless top-handle format, already has a compatible DEWALT 20V MAX battery and charger, uses T-shank blades, and wants both straight and orbital settings with a line-clearing blower. It is also a plausible package comparison for someone who would rather receive a battery and charger: DEWALT lists the DCS331M1 with a 4.0Ah DCB204 pack, charger, blade and bag. The M1 is the package variant, not an evidence-backed claim of a different DCS331 chassis.

Pause if the required blade is U-shank, if the job requires orbital action in hardwood or metal, or if a documented vacuum port, LED, brushless motor, runtime figure or cutting-depth limit is essential. None of those unknowns becomes certain because a retailer title mentions the broader DCS family. Confirm whether you are buying DCS331B or DCS331M1, what battery and charger are actually included, whether the stated blade shank suits your stock, and what the manual says for your material. The source-based assessment does not report test cuts, ownership, measured vibration, personal comfort, runtime, present price or availability.
