How to Choose the Right Battery Jigsaw for Your Projects? | Match Tool to Battery

Match the jigsaw to your existing battery platform first, then compare stroke rate, orbital settings, bevel stops, blade type, and grip style.

A tool-only jigsaw with no charger in the box is a steal — right up until you realize the battery you own won’t click into it. DEWALT uses the 20V MAX platform; Milwaukee runs on M18, and the two never swap. So the real first move is boring and it saves you a return label: open the drawer, read the label on the pack you already own, and buy inside that family. Once that’s settled, everything else — speed, orbit, bevel, grip — is a short list of specs you can compare in a couple of minutes. The table further down lines up the two platforms side by side.

What Specs Actually Change How the Saw Cuts?

Stroke rate sets your ceiling on speed, orbital settings set your ceiling on aggression, and bevel stops decide whether angled cuts are easy or fussy. Those three numbers matter more than brand loyalty.

Strokes per minute (SPM) is the blade’s up-and-down count. The DEWALT DCS331B 20V MAX runs at 3,000 SPM; Milwaukee’s 2737-series M18 FUEL jigsaws reach 0–3,500 strokes per minute. Higher SPM generally means faster cutting, though blade choice and material still dominate the result.

Orbital action pushes the blade slightly forward on the upstroke, which chews through rough lumber faster and leaves a rougher edge. Both cited platforms offer 4-position orbital action, so you get a clean setting for finished cuts and a fast one for framing. If a saw lists only on/off orbit, you lose that middle ground.

Bevel capacity is the angled-cut range. The DEWALT DCS331B carries 45° bevel capability, and Milwaukee’s D-handle 2737-20 uses a tool-less shoe bevel with detents at 0°, 15°, 30°, and 45°. Positive stops at those angles mean you can set a 45° cut by feel instead of eyeballing a protractor.

Which Grip Style Fits Your Hands and Your Cuts?

D-handle (top-handle) saws favor one-handed control and overhead work, while barrel-grip saws put your hand lower and closer to the work for better curve-tracing.

A D-handle gives you a loop to wrap your fingers around, which helps on plunge cuts and when you’re reaching. Milwaukee’s 2737-20 adds an LED light and a cut line blower, so the blade path stays visible under the dust.

Barrel-grip models sit in a different spot in your hand. The M18 FUEL Barrel Grip Jig Saw 2737B-20 runs 6 speed settings, the same 0–3,500 strokes per minute and 4-position orbital cutting, and offers ambidextrous switches with left and right controls — handy if you’re a left-handed user tired of reaching across the tool. Both cited Milwaukee models use T-shank blades, and the DEWALT switches blades keyless.

What Do People Get Wrong Before They Buy?

The most common mistake is ordering a bare tool without checking the charger, followed closely by buying blades that don’t fit the shank.

• Tool-only means tool only. The DEWALT DCS331B listing is explicit: battery and charger sold separately. If you’re new to the platform, price the kit version before you commit.
• Blade shank mismatch. The referenced Milwaukee jigsaws accept T-shank blades. Grabbing a U-shank pack means a blade that won’t seat properly.
• Judging on price alone. Kit versus bare tool drives most of the sticker difference, so two listings that look identical can be hundreds apart in what’s actually in the box.
• Ignoring dust and sight lines. A dust cover or extraction tube plus an on/off blower keeps the cut line readable, which matters more than most shoppers expect.
• Assuming platforms talk to each other. DEWALT 20V MAX batteries and Milwaukee M18 packs are not interchangeable, full stop. DEWALT does state the DCS335B works with all 20V MAX batteries and chargers, so staying in-family is genuinely worth it.

Weight is the last quiet factor. Bare-tool saws get tiring after a long run of overhead cuts, so if you’ll be holding the saw above shoulder height, a lighter body helps. If you want the shortlist of what actually tested well, our roundup of the best battery jigsaw picks for woodworking narrows it down fast.

Milwaukee also publishes a runtime figure for the top-handle M18 FUEL jigsaw — up to 32 m of cut in 19 mm OSB on a 5.0 Ah pack — though that spec comes from Milwaukee’s European site, which uses metric framing and isn’t a US price or availability source. Treat it as a rough capability signal, not a promise about your board.

Everything here applies to US cordless jigsaws sold through official manufacturer pages and major US retailers. Specs like these are worth checking against the current product page before you buy, since bundle contents and included accessories shift between runs. Milwaukee’s 2737-20 product page lists the full spec set for that model.
