Quick answer from a licensed plumber: On DeWalt 20V batteries, the DeWalt DCS359E1 kit: battery, charger and two blades included, four speed modes and a 4.2-degree oscillation angle, per DeWalt. On Bosch 18V, the GOP18V-40N bare tool, which stops itself at the end of a cut. For corded work, the DeWalt DWE315K kit, with a universal accessory adaptor and a depth guide. Use it for flush cuts on pipe and stubs and for clean drywall access holes, with a bi-metal blade for metal and plastic.

Our pick for most plumbers: the DeWalt DCS359E1 20V MAX XR oscillating multi-tool kit. Check the DeWalt DCS359E1 on Amazon

An oscillating multi-tool is the plumber’s tool for small, controlled cuts in finished spaces: trimming an old pipe or stub flush with the wall, cutting a clean opening in drywall to reach a valve or a trap, or notching around a pipe. This page compares three, two cordless and one corded, all sold by Amazon.com when we checked. Every spec comes from the makers’ own manuals and product pages.

Figures from DeWalt’s DCS359E1 and DWE315K pages and DCS359 manual, and Bosch’s GOP18V-40N page and manual. Each linked tool was sold by Amazon.com and in stock on October 5, 2026.

What Plumbers Use a Multi-Tool For

Flush cuts on pipe and stubs. Cutting an abandoned line or a stub flush with a wall or floor. DeWalt’s DCS359 manual lists plunge cutting and flush cutting among the jobs it is designed for.
Drywall access holes. A neat opening to reach a valve, a trap or a leak, sized so a patch or an access panel covers it. DeWalt lists drywall among the materials the DCS359 cuts, and Bosch’s GOP18V-40 manual gives plunge cuts in drywall as a job for its bi-metal plunge blade.
Plastic pipe. DeWalt lists PVC and plastic for the DCS359, and Bosch’s GOP18V-40 manual lists removing excess copper or PVC pipe as a flush-cutting job.

Plumber’s note: a multi-tool cut is not a square, deburred end. For a new joint you will solder, press or glue, cut with a proper tool from our pipe cutter picks or PEX cutter picks. The multi-tool is for the cut those tools cannot reach.

Pick the Blade for the Material

The tool only moves the blade. Bosch lists its Starlock bi-metal plunge cut blades for wood and non-hardened metal, including wood with nails, with a 1.5-inch immersion depth in every width it lists. Its bi-metal flush cut blade has a segmented edge for straight or flush cuts. Bosch says Starlock blades also work with OIS-compatible tools from other brands, including Makita.

Check the mount before you buy blades. DeWalt’s DCS359 takes universal-fit, Starlock and Starlock Plus accessories, with an adapter and a longer pin for Starlock Plus. The Bosch GOP18V-40N takes Starlock, StarlockPlus and StarlockMax. DeWalt includes a universal accessory adaptor with its corded DWE315K kit for most other brands. We do not link blades: the Diablo oscillating blade listings we found on Amazon were mostly from third-party sellers or down to a few left.

Best Cordless Kit

DeWalt DCS359E1 20V MAX XR Oscillating Multi-Tool Kit

20V MAX, 1.7Ah battery and charger included · brushless · 4.2-degree oscillation angle · four speed modes, about 8,000 to 20,000 OPM · lock-on and lock-off · LED work light · 11.7 in. long, 2.88 lb (DeWalt spec list) · 3-year limited warranty

This is the multi-tool I would point a plumber to who already runs DeWalt 20V batteries. DeWalt says it makes cuts through wood, metal, drywall, PVC and plastic, and its manual lists plunge cutting and flush cutting among the jobs it is built for. That covers the two cuts plumbers make most with this tool: trimming a pipe or stub flush with a wall or floor, and cutting a clean opening in drywall to get at a valve or trap.

It has a brushless motor and a 4.2-degree oscillation angle, per DeWalt. A mode selector gives four speeds, which the manual lists as about 8,000, 12,000, 16,000 and 20,000 oscillations per minute, and the trigger varies speed within each mode. The LED is meant for work under cabinets and between walls; the manual says it stays on for 20 seconds after you let go of the trigger. The lock-on button shuts the tool off on its own after five minutes. The kit includes a 1.7Ah battery, a charger, a fast-cut wood blade, a wood-with-nails blade and a sanding platen.

Kit: battery, charger and two blades included
Cuts wood, metal, drywall, PVC and plastic, per DeWalt
Four speed modes plus variable trigger
Takes universal-fit, Starlock and Starlock Plus accessories, per the manual

Starlock Plus blades need an adapter and a longer pin, per DeWalt
Lock-on shuts off after five minutes of continuous use
Kit blades are for wood and wood with nails, per DeWalt

Verdict: The pick for plumbers on DeWalt 20V batteries who want one kit that is ready to cut.

Best Cordless Bare Tool

Bosch GOP18V-40N 18V Brushless StarlockMax Oscillating Tool

Bosch 18V battery (bare tool) · brushless · 10,000 to 20,000 OPM, six speed settings · 4-degree oscillation angle · Auto-Stop · StarlockMax mount · 11 in. long, 2.7 lb · one blade included · 5-year limited warranty

Bosch names plumbers among the trades this tool is built for. It runs on Bosch 18V batteries and is sold as a bare tool with one blade. The brushless motor gives 10,000 to 20,000 oscillations per minute across six speed settings, and Bosch lists a 4-degree oscillation angle.

Two features suit work inside finished walls. Auto-Stop halts the tool once it reaches the end of the cut, which Bosch says helps prevent damage to the workpiece, and Adaptive Speed Control gives a soft start before the tool climbs to the speed you chose. The StarlockMax mount takes Starlock, StarlockPlus and StarlockMax accessories, and the snap-in lever releases the blade without touching it. Bosch says the vibration design reduces fatigue by 80 percent compared with its predecessor.

Bosch names plumbers among its trades
Auto-Stop at the end of the cut
Takes all three Starlock blade families, per Bosch
5-year limited warranty on Bosch 18V tools

Bare tool: battery and charger sold separately
Only one blade in the box
Bosch lists only Starlock-family accessories for it

Verdict: The pick for plumbers on Bosch 18V batteries, or anyone who wants Auto-Stop for cuts in finished walls.

Corded Kit With Accessories

DeWalt DWE315K Oscillating Multi-Tool Kit

Corded, 3 amp · brushed motor · dual-grip variable speed trigger · 22,000 OPM (DeWalt spec list) · Quick-Change accessory system · universal accessory adaptor · LED · depth/height guide · 29-piece accessory kit and contractor bag · 3-year limited warranty

The DWE315K is DeWalt’s corded kit. It has a 3 amp brushed motor and a dual-grip variable speed trigger, and DeWalt’s spec list gives 22,000 oscillations per minute. The Quick-Change system swaps blades without wrenches, and the universal accessory adaptor fits most brands of oscillating blades, per DeWalt.

It comes with a guide that sets the depth or height of a cut so you can repeat it, an LED light, and a 29-piece accessory kit with a storage box and a contractor bag. DeWalt lists a wood-with-nails blade, a fast-cut wood blade, a semi-circle blade, a sanding pad and 25 sheets of sandpaper. DeWalt does not list any of those blades for metal, so buy a metal-cutting blade for pipe work.

Universal adaptor fits most blade brands, per DeWalt
Depth guide for repeatable cuts
Three blades, sanding pad and paper included
3-year limited warranty

Corded, brushed motor
No kit blade listed for metal
DeWalt lists no oscillation angle for it

Verdict: A plain corded kit for plumbers who want a depth guide and a bag of accessories.

What About Makita and Milwaukee?

Makita sells a corded multi-tool kit, the TM3010CX1. We do not link it: when we checked on October 4, its Amazon listing was from a third-party seller. Milwaukee makes M12 and M18 multi-tools, but the Amazon listings we found for them were from third-party sellers too. If you are on Milwaukee batteries, or you want the Makita, buy from a dealer you trust and read the maker’s own specs.

Before You Buy

Match your batteries. The DeWalt DCS359E1 kit includes a battery and charger; the Bosch is a bare tool.
Check the blade mount. Starlock, Starlock Plus, StarlockMax and universal-fit blades do not all fit every tool; see the blade section above.
Buy a blade for metal. The DCS359E1 kit blades are listed for wood and wood with nails, DeWalt lists no kit blade for metal with the DWE315K, and Bosch does not say which blade comes with the GOP18V-40N.
Corded or cordless. Cordless for under-sink and crawl space work; corded if the tool lives on a cart near an outlet.
Plan the access hole. Cut it to a size an access panel or a patch will cover.

Safety: Cutting Into Walls and Floors

Bosch’s GOP18V-40 manual says to use a metal detector to find gas or water pipes hidden in the work area, and warns that cutting into a gas line will cause an explosion and water entering an electrical device may cause electrocution. If you must cut into a wall where wiring may run, it says to disconnect the fuses or breakers feeding the area. DeWalt’s DCS359 manual says to check for hidden wiring, gas lines and other utilities before any cut, and to hold the tool by its insulated gripping surfaces where the blade may contact hidden wiring. Both manuals say never to work in an area soaked with a liquid such as water. DeWalt also says to clamp or support the work, keep your hands out of the cutting area, never reach under the material, wear gloves when changing blades because they are sharp and get hot, and take frequent breaks, because the tool’s vibration can injure fingers, hands and arms over long use.

FAQ

Can an oscillating multi-tool cut copper or PVC pipe?

With the right blade, yes. DeWalt says its DCS359 cuts wood, metal, drywall, PVC and plastic. Bosch lists its Starlock bi-metal plunge blades for wood and non-hardened metal, and the GOP18V-40 manual names removing excess copper or PVC pipe as a flush-cutting job, with a bi-metal plunge blade for flush cutting a copper pipe. Pick a blade its maker lists for metal. For a new joint you will solder, press or glue, a tubing or pipe cutter gives a squarer end.

Will Bosch Starlock blades fit a DeWalt multi-tool?

DeWalt’s DCS359 manual says the tool takes universal-fit, Starlock and Starlock Plus accessories, and that Starlock Plus needs an adapter and a longer pin. For the corded DWE315K, DeWalt says its universal accessory adaptor is for use with most oscillating tool accessory brands; its page and manual do not name Starlock. Bosch says its Starlock blades also work with OIS-compatible tools.

Oscillating tool or reciprocating saw for plumbing?

Use the oscillating tool for controlled cuts: trimming a pipe or stub flush with a wall or floor, and cutting a neat drywall opening. DeWalt’s DCS359 manual lists plunge cutting and flush cutting among its jobs. Use a reciprocating saw for demo and for cutting larger pipe in place.

Can I cut into a wall that is wet from a leak?

Not while it is soaked. DeWalt’s and Bosch’s manuals both say never to work in an area soaked with a liquid such as water, because of the shock hazard. Shut the water off, let the area dry, and then cut.

How do I avoid hitting pipes or wires when I cut drywall?

Bosch’s manual says to use a metal detector to find gas or water pipes in the work area, and to shut off the breakers feeding the area if you must cut into a wall where wiring may run. DeWalt says to check for hidden wiring, gas lines and other utilities before any cut, and to hold the tool by its insulated gripping surfaces.

Bottom Line

Buy the multi-tool that runs on the batteries you already own: the DeWalt DCS359E1 kit or the Bosch GOP18V-40N. For corded work, the DeWalt DWE315K kit. Then buy a bi-metal blade that fits its mount, find the pipes and wires before you cut, and never cut into a wall that is still wet.
