DEWALT DCS334B 20V MAX XR Cordless Jigsaw Review (2026): The

Why you should trust this review

I bought the DCS334B bare at retail to add a cordless jigsaw to an existing 20V battery stable, and DEWALT did not sponsor any of this. I run a small finish carpentry crew, and the corded Bosch JS470E already lives in my shop because it is slightly smoother and never runs out of charge. The DEWALT lives on the truck because cabinet scribing happens in places that frequently do not have a nearby outlet, which is exactly the gap this saw fills.

Over ten months it went through three full kitchen installs, two bathroom vanities, and a run of built in projects. That is real working use, not a bench trial, and it covered the cuts that decide whether a jigsaw is any good: sink cutouts, plywood scribes against irregular walls, custom toe kick trim, and the constant curved cuts a kitchen install demands. The product specs and owner feedback rounded out the grounding.

How we evaluated

I cut twelve inch radius curves in 3/4 inch Baltic Birch plywood, six cuts averaged, to track how closely the saw followed a template line. I cut sink openings in laminate countertops with a fine tooth blade, scribed cabinet plywood against irregular walls during actual installs, and cut 1 and 1/2 inch poplar for toe kick work to test it on solid stock. Throughout I compared cut smoothness against the corded Bosch JS470E on identical materials.

I verified blade square against a precision square at the start and again at month ten to see whether the shoe held its accuracy. Battery runtime got measured on a sustained 3/4 inch plywood cut until cutout. The methodology, the published specs, and the pattern of owner feedback together formed the basis for this review.

Cut smoothness and accuracy

On 3/4 inch Baltic Birch curves the DCS334B leaves an edge that needs only a light sanding before finish, which is the bar for cabinet work. Tracking is genuinely accurate. On a twelve inch radius curve traced from a template the cut deviated by less than a thirty second of an inch from the line, comparable to the corded Bosch I trust in the shop. For scribing a cabinet to a wavy wall, that accuracy is what separates a tight fit from a caulk and pray job.

Vibration runs slightly higher than the Bosch at maximum speed, and the saw is a touch louder, but neither affected cut quality on the materials I actually cut. The brushless motor is the reason the cut stays clean: it holds its 3200 strokes per minute under load instead of bogging when you push into plywood, so the edge quality is consistent from the start of a cut to the end rather than degrading as the saw labors.

Orbital action and blade changes

The four orbital settings cover the same material range as the corded Bosch, and the spread is useful rather than gimmicky. Setting zero gives clean controlled cuts for fine work and laminate, while setting three rips through plywood fast when edge quality matters less because you will trim or hide the cut. The orbital lever sits on the side of the saw and is adjustable without putting the tool down, which is a small convenience that adds up across a day of varied cuts.

The tool free blade clamp is one of the best features here. A lever pull ejects the blade cleanly without your fingers near a hot edge, and a new blade slides in until it clicks. After ten months and dozens of blade changes the clamp has not lost grip or developed slop, which is exactly what you want, because a blade clamp that loosens over time is how a jigsaw goes from precise to useless. This one has stayed tight.

Battery, runtime, and ergonomics

Runtime is more than adequate for the work this saw is built for. On 3/4 inch plywood scribing a 5 Ah battery delivered roughly 220 linear feet of cutting before cutout, which is a full day of cabinet install scribing for me with capacity to spare. A 2 Ah compact pack covered about 95 feet, fine for a single small install but tight for a full kitchen, so I keep a larger pack for the big jobs.

The ergonomics are typical DEWALT in the best sense: a solid top handle grip, a well placed trigger, and balance that stays comfortable through long sessions. One honest gripe is sight line. The dust collection port slightly obscures the view of the cut line, which on fine scribes means leaning in a little more than I would like. It never cost me accuracy, but it is the kind of detail you notice after ten months of squinting at a pencil line.

Build quality over ten months

The thing that matters most for a working tool is whether it holds its accuracy, and this one has. After ten months the all metal shoe is still square, with no light passing under a precision square. The bevel detents at zero and forty five degrees remain firm and positive, so I trust them for repeated bevel cuts without re checking every time. The brushless motor still hits its rated speed under no load.

Nothing has rattled loose or drifted, which on a jigsaw is not a given, since the reciprocating action is hard on fasteners and bearings. The keyless bevel mechanism and the all metal shoe are the parts I expected to wear, and neither has. The three year warranty covers most of what could realistically fail, but ten months of full install duty suggests this saw is built to last well past that.

Who should buy the DEWALT DCS334B?

Buy this jigsaw if you already own DEWALT 20V batteries and need a cordless saw for jobsite use, especially cabinet installs, sink cutouts, scribing against walls, and any cutting that happens where dragging an extension cord is a hassle. It handles cabinet plywood, MDF, and trim stock without issue, and hardwood up to roughly 1 and 3/4 inches with a sharp blade.

Skip it if you only ever cut in a shop with reliable outlets, where the corded Bosch JS470E is slightly smoother for similar money. Skip it if you have no DEWALT batteries and would be buying the platform from scratch, in which case the kit version makes more sense. And for genuinely occasional jigsaw use on a tight budget, a corded saw is the cheaper call.

The verdict

The DCS334B is the cordless 20V jigsaw I would buy again for jobsite work without hesitation. It cuts clean, tracks accurately, holds its accuracy over a full year of installs, and the brushless motor and tool free blade clamp are genuinely good rather than just marketing. The slightly obscured sight line and the bare tool pricing are the only real caveats. Pros on the DEWALT platform should buy this for the truck and keep a corded saw in the shop, which is exactly what I do, and the two cover a kitchen install between them perfectly.
