Electricians today face tighter deadlines, more complex wiring, and the constant need to move between rough-in, trim-out, and service calls. Cordless tools have become essential for keeping pace without being tethered to an outlet. In 2025, the best cordless tools for electricians combine lightweight ergonomics, long runtime, and smart power management — qualities that Milwaukee’s M12 and M18 platforms deliver in spades. Whether you’re bending conduit, cutting PVC, or installing cable trays, this guide breaks down the must-have cordless solutions for electrical work.

Why Cordless Tools Are a Game-Changer for Electrical Work

Cordless tools eliminate the hassle of extension cords, reduce tripping hazards, and give you the freedom to work in tight attics, crawlspaces, or outdoor job sites where power isn’t available. For electricians, the ability to quickly switch between drilling, cutting, fastening, and even plumbing prep (like PEX expansion) with a shared battery system saves serious time. Milwaukee’s M12 line is particularly popular for its compact size and surprising power, while the M18 system handles heavier tasks with ease. The M12 12V Lithium-Ion Cordless Combo Kit with Two 2.0Ah Batteries, Charger and Bag (5-Tool) is a great entry point, offering a versatile set for everything from drilling to cutting.

Cutting Tools: Conduit, PVC, and Cable

PVC Shears and Shear Kits

Cutting PVC conduit and pipe is a daily task for many electricians. Manual shears work, but they can fatigue your hand after dozens of cuts. Cordless shears speed up the process dramatically. The M12 12V Lithium-Ion Cordless PVC Shear Kit with One 1.5 Ah Battery, Charger and Hard Case is a top choice — it makes clean, burr-free cuts in schedule 40 and 80 PVC with a simple trigger pull. The compact size fits easily into a tool bag, and the hard case keeps everything organized. For electricians working on underground or exposed conduit runs, this tool is a time-saver.

Reciprocating Saws for Demolition and Conduit Work

When you need to cut through metal studs, threaded rod, or old conduit, a reciprocating saw is indispensable. Milwaukee’s M18 FUEL line offers industry-leading cutting speed and vibration control. The M18 FUEL 18V Lithium-Ion Brushless Cordless HACKZALL Reciprocating Saw with (1) 5.0 Ah, (1) 2.0 Ah Battery and Charger is a compact powerhouse that fits into tight spots where a full-size Sawzall won’t go. Its orbital action reduces binding, and the included batteries give you all-day runtime. For electricians who do a mix of rough-in and remodel work, this is one of the best cordless tools for electricians in 2025.

Fastening and Stapling Tools

Cable Staplers for Low-Voltage and Structured Wiring

Running low-voltage cable (like Cat6, speaker wire, or thermostat cable) requires secure, code-compliant stapling. A cordless cable stapler beats a hammer and manual stapler in speed and consistency. The M12 12 Volt Lithium Ion Cordless Cable Stapler w/1 in. Insulated Cable Staples 600 Per Box (2-Pack) is purpose-built for this job. It drives insulated staples that won’t crush or cut the cable, and the two-pack of staples keeps you working without reloading. This tool is especially valuable for security system installers, data center techs, and residential electricians pulling low-voltage lines.

Plumbing Prep for Electricians: Water Transfer and Heat

Submersible Water Transfer Pumps

Electricians often encounter wet basements, flooded trenches, or need to drain pipes before working on fixtures. A cordless submersible pump saves the day. While not a traditional electrical tool, the M12 12-Volt Lithium-Ion Cordless 9 GPM 0 HP Submersible Stick Water Transfer Pump w/M12 4.0Ah Batt and Charger is a compact solution that fits in a 5-gallon bucket. It moves up to 9 gallons per minute — plenty for draining small areas. The included battery and charger ensure you’re ready on the spot. For electricians who also handle some plumbing (like sump pump installs), this tool bridges both trades.

Compact Heat Guns for Shrink Tubing and Bending

Heat guns are essential for heat-shrink connectors, bending PVC conduit, and thawing frozen pipes. Cordless heat guns offer portability where an extension cord won’t reach. The M18 18-Volt Lithium-Ion Cordless Compact Heat Gun with (1) 2Ah Battery delivers up to 1,100°F and features a compact body for one-handed use. It heats up quickly and has two speed settings, making it ideal for precise shrink-wrap work on control panels or outdoor junction boxes. The included 2.0Ah battery keeps it light enough for overhead work.

Batteries and Charging: The Backbone of Your Cordless Fleet

No tool guide is complete without discussing batteries. Milwaukee’s M18 REDLITHIUM XC batteries offer extended runtime and fade-free power. If you’re running multiple high-drain tools on a crew, consider bulk battery packs. The M18 18V Lithium-Ion XC Extended Capacity Battery Pack 5.0Ah (10-Pack) is an economical way to keep an entire team charged. Each battery provides 5.0 amp-hours, enough for a full day of drilling, sawing, or heat-gun work. With ten packs, you can rotate batteries through a multi-bay charger and never lose momentum.

M12 vs. M18: Which Platform for Electricians?

Electricians often debate M12 vs. M18. The M12 system (12V) excels in compact, lightweight tools like ratchets, shears, and cable staplers. It’s ideal for finishing work and tight spaces. The M18 system (18V) delivers more power for cutting, drilling, and heavy demolition. Many electricians carry both — M12 for trim-out and M18 for rough-in. Milwaukee’s cross-platform battery compatibility (both use the same charger) makes mixing easy. For a well-rounded kit, start with the M12 combo kit and add M18 saws or heat guns as needed.

How to Choose the Right Cordless Tools for Your Business

Consider your daily tasks: if you do mostly service work and panel changes, focus on compact tools like the M12 ratchet and PVC shear. If you’re doing new construction or heavy commercial, invest in M18 saws and high-capacity batteries. Always buy kits that include batteries and chargers — tool-only purchases can save money if you already have a platform, but kits offer the best value for starting fresh. Check the battery amp-hour rating: 2.0Ah is fine for light tools, but 5.0Ah or 8.0Ah is better for saws and heat guns.

Final Recommendations for 2025

The best cordless tools for electricians in 2025 are those that combine power, portability, and reliability. Milwaukee’s M12 and M18 platforms deliver on all fronts. For cutting PVC and cable, the M12 PVC Shear and Cable Stapler are unbeatable. For demolition and conduit work, the M18 HACKZALL or Super SAWZALL are top performers. And for specialty tasks like water transfer and heat shrinking, the M12 pump and M18 heat gun fill essential gaps. By investing in a shared battery system, you streamline your tool inventory and reduce downtime.
