Best Cordless Jigsaws 2026: 20V, Orbital & Variable Speed

The Milwaukee 2645-20 M18 18-Volt Cordless Jig Saw runs on the M18 battery platform -- compatible with 250+ M18 tools, making battery sharing practical across a full cordless tool collection. Orbital action settings (0-3) improve cutting speed in wood by up to 50% over non-orbital cutting. The tool-less T-shank blade change swaps blades in under 10 seconds without tools. Electronic speed control maintains consistent speed under load. Sold as bare tool -- requires an M18 battery. For Milwaukee M18 owners, this is a natural addition to the collection. For new buyers, factor in one M18 battery and charger kit cost.

The BLACK+DECKER BDCJS20B 20V MAX Cordless Jig Saw covers the fundamental jigsaw function -- variable speed trigger, T-shank blade compatibility for wide blade selection, and the 20V MAX platform shared across BLACK+DECKER's cordless tool line. Sold as a bare tool; pairs with any BLACK+DECKER 20V MAX battery. Without orbital action or the electronic speed control of premium jigsaws, it cuts slightly slower in wood and bogs more under heavy load, but for occasional cuts in plywood, trim, and drywall it is entirely adequate. The 20V MAX platform also includes circular saws, drills, and sanders for users building out a cordless tool kit.

The DeWalt DCS331B is the entry-level option in the DeWalt cordless jigsaw lineup — a 20V MAX bare-tool jigsaw that runs on the same battery as DeWalt drills, circular saws, and impact drivers in the 20V ecosystem. Variable speed reaches 2,500 SPM (strokes per minute), covering a range from slow, controlled scrollwork in thin material to faster cutting through lumber and plywood. Keyless blade change allows T-shank jigsaw blades to swap without tools, which matters during mid-project blade changes. The orbital action setting adjusts blade movement for more aggressive cutting in wood or finer, more precise movement in metal and laminates. The DCS331B uses a brushed motor, which is the primary trade-off versus the newer DCS334B in this category. Brushed motors are less energy-efficient, generate more heat under sustained cutting loads, and have a shorter service life than brushless designs. The 2,500 SPM ceiling is also lower than the DCS334B. For a homeowner or occasional user already in the DeWalt 20V ecosystem who wants a capable jigsaw at the lowest entry price without buying into a new battery platform, the DCS331B covers the common tasks — cutting curves in plywood, notching drywall, trimming door casings — reliably. For a contractor or frequent user, the brushless DCS334B is the better long-term investment despite the higher upfront cost.

The Bosch JS120BN is a 12V Max cordless jigsaw built around one distinguishing characteristic: weight. At 2.9 lbs it is the lightest jigsaw on this page by a meaningful margin — a practical advantage during overhead cuts, vertical panel work, and extended cabinetry detail sessions where arm fatigue accumulates over a day. Variable speed reaches 2,300 SPM with orbital action for material-matched cutting. The compact form factor and low mass make it particularly well-suited for finish carpentry and precision curved cuts where control matters more than raw cutting speed. The 12V platform is the meaningful trade-off. Compared to the 18V and 20V tools on this page, the JS120BN has less torque in reserve for pushing through dense hardwood, thick dimensional lumber, or stacked material. For light-duty tasks — cutting curves in 3/4-inch plywood, trimming MDF shelving, scribing cabinetry to walls — 12V is entirely adequate. For framing cuts, deck boards, or repeated cuts through 2-inch hardwood, an 18V or 20V tool is more appropriate. The Bosch 12V battery system is smaller than the 18V/20V platforms at Milwaukee, DeWalt, and Makita, so buyers should confirm they either already own Bosch 12V batteries or are comfortable starting in that ecosystem. At $129.99 for the bare tool, it is the precision-focused specialist on this page.
