Best compact cordless reciprocating saw for plumbing service calls

A full-size demolition saw is a lot to carry for one awkward pipe cut. A compact cordless recip earns its spot on a plumbing service van by getting into the repair, taking the right blade and sharing batteries with tools already in the bag.

For an M12 service kit, choose Milwaukee’s 2520-20 FUEL HACKZALL. For a DeWalt 20V MAX kit, choose the ATOMIC DCS369B. Makita XRJ08Z is the pick for LXT crews who want spring-assisted blade ejection; Bosch GSA18V-24N fits a Bosch 18V kit with an in-line body and a 0.94-inch stroke. These exact listings are bare tools: budget space in the bag for a compatible battery and charger too.

Quick picks for the service bag

Your kit or priority	Pick	Why it earns the spot
M12 batteries already power your plumbing tools	Milwaukee M12 FUEL 2520-20	A 5/8-inch stroke, variable speed and QUIK-LOK blade changes on the M12 platform
DeWalt 20V MAX batteries in the van	DeWalt ATOMIC DCS369B	A 12.5-inch body, pivoting shoe and tool-free blade release
Frequent blade changes between repair tasks	Makita XRJ08Z	Spring-assisted blade ejection and wood, all-purpose and metal starter blades
Bosch 18V batteries already on charge	Bosch GSA18V-24N	In-line design, variable trigger and wood/metal blades included

Start with the battery shelf. A second charger and a different spare pack are extra things to remember on a busy morning. Change platforms for a feature you will use, rather than a bigger voltage label.

Published specifications side by side

Saw	Stroke length	No-load strokes per minute	Published weight and basis	Battery platform	Exact listing
Milwaukee 2520-20	5/8 inch	0–3,000	3.2 lb on the current 2520-20 product page	Milwaukee M12	Bare tool
DeWalt DCS369B	Not listed on the current US product page	Up to 2,800	3.13 lb, tool only	DeWalt 20V MAX	Tool only
Makita XRJ08Z	7/8 inch	0–3,100	4 lb without battery; 5.5 lb with battery	Makita 18V LXT	Tool only
Bosch GSA18V-24N	0.94 inch	0–3,100	3.75 lb in the technical table; rounded to 3.8 lb in the overview	Bosch 18V / AMPShare	Bare tool

Compare the weight basis as well as the number. Makita supplies both bare and battery-fitted figures; Milwaukee and Bosch’s current specification tables label their figures simply as weight. Your battery choice changes what you carry. No-load SPM describes the mechanism, not a timed cut through your particular pipe and blade.

The Milwaukee manual supplies stroke and speed; its current product specifications supply the displayed weight. Compare those with the DeWalt US page, Makita specifications and Bosch GSA18V-24N specifications.

Milwaukee M12 FUEL HACKZALL: best for an M12 service bag

Why you’ll like it: If an M12 drain tool or press tool is already part of your routine, the 2520-20 keeps the cutting tool on that same battery system. Its brushless motor, variable-speed trigger and compact layout suit a carry-in repair kit without adding a full-size recip to every call.

The manual specifies a 5/8-inch stroke and up to 3,000 SPM. The QUIK-LOK clamp accepts HACKZALL and SAWZALL blades, giving you a familiar blade format when moving between materials.

Good to know: The 2520-20 is the bare-tool pick, not the 2520-21XC battery kit. Milwaukee’s product page explicitly excludes the XC4.0 pack. Bring the compatible M12 battery and charger from your kit.

DeWalt ATOMIC DCS369B: best for DeWalt 20V MAX crews

Why you’ll like it: The ATOMIC is a straightforward addition to a DeWalt service van: a 12.5-inch body, a variable trigger and a pivoting shoe to keep contact with the work. The LED helps illuminate the cutting area when the repair is tucked into a cabinet or utility space.

DeWalt lists 3.13 lb for the tool-only saw and up to 2,800 SPM. The tool-free release handles blade swaps; the supplied belt hook gives it a parking spot between tasks.

Good to know: DCS369B includes two blades and the belt hook, with battery and charger sold separately. The current US product page lists those contents; its battery-kit variants have different suffixes.

Makita XRJ08Z: best blade-change setup

Why you’ll like it: Makita’s spring-assisted keyless ejection is the feature to choose when your repair jumps from one material to another. Release the blade without reaching for its hot cutting end, then load the blade for the next task. The pivoting shoe and constant-speed control round out a useful LXT service tool.

The 7/8-inch stroke runs at up to 3,100 SPM. Makita gives a 14-3/8-inch overall length and separates the 4 lb bare weight from its 5.5 lb battery-fitted figure.

Good to know: XRJ08Z comes with an 8-inch wood blade, a 6-inch all-purpose blade and a 6-inch metal blade. Battery and charger are separate. The maker’s specification and contents list names the three blades, so you can build out the rest of the pouch around the materials you cut.

Bosch GSA18V-24N: best for Bosch 18V crews

Why you’ll like it: Keep a Bosch battery kit working with an in-line saw that Bosch designs for close-to-the-wall cuts. The 13.3-inch body, LED and variable trigger make a practical combination for placing the blade and easing into a service cut.

The GSA18V-24N has a 0.94-inch stroke and up to 3,100 SPM. Its tool-free blade change keeps the accessory swap simple. Use the exact model number here: the older GSA18V-083B has different specifications.

Good to know: This bare-tool listing includes one wood-cutting and one metal-cutting blade. The current Bosch page identifies Bosch 18V/AMPShare compatibility and notes that CORE18V batteries are sold separately.

Pack the blade for the pipe

A small saw with the wrong blade still makes an awkward repair. Keep material-matched blades together in a pouch, with enough length to clear the work through the whole stroke. A long blade also needs room behind the pipe: look at the exit path before starting the cut.

Milwaukee’s 2520-20 manual accepts different blades for metal, wood and other tasks, and says not to use blades shorter than 3-1/2 inches. DeWalt’s DCS369 instructions call for the shortest suitable blade that extends beyond the shoe and workpiece throughout the cut; jigsaw blades are excluded.

Remove the battery for blade changes, support the work and identify hidden services before cutting, following the tool manual. Keep the shoe against the work as instructed rather than letting the pipe bounce against the blade.

Tip: Pack the spare blade beside the spare battery. Finding the saw is easy; finding the right metal blade halfway through a repair is the part that wastes the visit.

For a press-fitting repair, use the fitting maker’s specified cutting and preparation procedure for the new joint. The recip is handy for removing the old section; our compact pipe press guide covers the press-tool and jaw side of the kit.

Finish the repair and leave a useful record

The saw handles removal, while the rest of the service kit diagnoses and completes the repair. Pair it with an inspection camera when you need a view inside the line, or a drain snake when the call is a blockage rather than a pipe replacement. Keep a compact wet/dry vacuum ready for cleanup.

Make Jobber the handoff after the cut: keep the repair photos, parts and time with the job the office will bill.

In Jobber, add the removed pipe material, replacement parts, time spent and before/after photos to the job record. Notes and attachments let the next person see what changed, with linking options across jobs, quotes and invoices.

HCP alternative: record those same details in a private job note from the field. Keep an internal labor note useful to the office, then enter billable parts and time through your normal invoicing workflow.

A good closeout is short: what failed, what you removed, what you installed, how long it took and a clear photo. That is the difference between a completed cut and a completed service call.

Working on an expansion fitting instead? Our cordless PEX expansion-tool guide matches F1960 tools, head sizes and kit contents to residential repair work.

For a controlled cut in copper water tube, see our powered copper cutter and manual backup picks, with a size chart and cut-end preparation checklist.

Once the cutting and repair work is done, our cordless caulk gun picks help match the sealing tool to the cartridge, battery platform and finished joint.

For a neat cabinet opening or a flush cut beside trim, use our cordless oscillating multi-tool picks: four battery-platform fits and the blade to use on wood, pipe or grout.

For controlled cuts on exposed metal stock, compare the openings and blade sizes in our compact cordless band saw guide.
