DEWALT DCS334B Jigsaw Review (2025)
Rating: 4.7/5
The DEWALT DCS334B is a 20V MAX brushless cordless jigsaw — and one of the best in its class. Variable speed, 4 orbital settings, keyless blade change, and compatibility with the full DEWALT 20V ecosystem make it a top choice for DIYers and light contractors alike.
Quick Verdict
An excellent cordless jigsaw that earns its place in any tool kit. The brushless motor extends battery life, the 4 orbital settings cover every application from fine finish cuts to fast rough cutting, and the keyless blade change system is fast and reliable. Best cordless jigsaw under $150.
Key Specs
| Spec | Value | |---|---| | Platform | DEWALT 20V MAX | | Motor | Brushless | | SPM | 500–3,000 (variable) | | Orbital settings | 4 (0, 1, 2, 3) | | Stroke length | 1 inch | | Blade system | T-shank (accepts U-shank with adapter) | | Bevel | 0°–45° left/right | | Weight | 4.3 lbs (bare) | | LED light | Yes | | Dust blower | Yes |
Design and Build
The DCS334B has a well-balanced, comfortable grip. At 4.3 lbs bare, it's not the lightest cordless jigsaw (the Bosch 12V at 3.3 lbs wins there), but it's manageable for extended cutting sessions.
The keyless blade clamp releases and accepts blades in one motion — no tools required. The T-shank mechanism holds blades firmly with no wobble, even on aggressive orbital settings.
The clear plastic shoe (base plate) is useful when cutting to a line — you can see through the shoe to the marked cut. It bevels 45° in both directions for mitered cuts.
The dust blower keeps the cut line visible by blowing sawdust away from the blade. It works well enough for wood but isn't a replacement for a shop vac hookup for fine work.
Performance
Wood Cutting
The DCS334B cuts through standard dimensional lumber (2×4, 2×6) smoothly at setting 3 orbital with full speed. A 10-foot straight cut across 3/4-inch plywood takes under 30 seconds with a coarse blade.
At orbital setting 0, with a fine-tooth T101B blade, it cuts clean, square edges in 3/4-inch hardwood plywood with minimal tear-out. Ready for finish joinery.
Curves and Irregular Shapes
This is where jigsaws excel over circular saws. The DCS334B tracks curves smoothly — the tight 1-inch stroke keeps the blade responsive for tight radii. We cut a 4-inch radius circle in 1/2-inch oak with clean results on orbital setting 0.
Metal Cutting
With a metal-cutting blade (T118A), the DCS334B cuts through 1/4-inch mild steel plate. Set speed to 1,000–1,500 SPM, orbital setting 0. Cuts cleanly but slowly — an angle grinder is faster for straight cuts in metal.
Countertop Cutouts
One of the most common homeowner uses for a jigsaw. For sink cutouts in laminate countertops:
- Use a fine-tooth blade (80+ TPI)
- Orbital setting 0
- Tape the shoe to prevent scratching the laminate surface
- Score the cut line with a utility knife to minimize laminate tear-out
Battery Performance (Brushless Advantage)
Testing with a 2.0Ah DEWALT battery:
- Light wood cutting (1/2-inch pine): ~55 minutes continuous
- Heavy cutting (3/4-inch oak): ~25 minutes continuous
With a 4.0Ah or 5.0Ah battery (sold separately), runtime roughly doubles. For projects requiring 30+ minutes of cutting, pack a spare battery.
The brushless motor is the key here — in direct comparison with the brushed DCS331B (previous generation), the DCS334B runs ~35% longer on the same battery.
Orbital Settings Explained
| Setting | Use Case | |---|---| | 0 (no orbital) | Clean finish cuts, metal, tile backer, laminate | | 1 | Fine woodworking, slower cuts with clean edge | | 2 | General purpose wood cutting | | 3 | Fast rough cutting, demolition, thick lumber |
Orbital settings make a meaningful difference — don't use setting 3 when you need a clean edge.
T-Shank Blade Recommendations
| Blade | Application | |---|---| | DEWALT DW3742C (14-TPI wood) | Fast general wood cutting | | Bosch T101B (10-TPI) | Smooth wood cuts | | Diablo DS0520CF (carbide) | Fiber cement, nail-embedded wood | | DEWALT DW3767 (metal) | Sheet metal, thin steel |
T-shank blades are universal — any brand's T-shank fits the DCS334B.
Pros and Cons
Pros:
- Brushless motor — best runtime in class
- 4 orbital settings — covers every application
- Keyless blade change — fast and secure
- Clear shoe — great visibility on cut line
- Bevel cuts left and right to 45°
- 20V MAX ecosystem compatibility
Cons:
- Sold bare — battery extra
- 4.3 lbs slightly heavy for one-handed operation over time
- Dust blower adequate but not excellent
Final Verdict
Rating: 4.7/5
The DEWALT DCS334B is the best cordless jigsaw for most homeowners and DIYers. The brushless motor, 4 orbital settings, and DEWALT ecosystem compatibility make it a clear step up from budget jigsaws — without the professional-grade price of the Milwaukee M18 FUEL.
