For electricians comparing Milwaukee power tools, my best overall pick is the Milwaukee 2226-20 Non-Contact Voltage Detector and GFCI Receptacle Tester, since it combines two useful checks in one device. The 2235-20 400 Amp Clamp Meter is a focused choice for current measurements, while the M12 HACKZALL suits compact cutting tasks. The main tradeoff is between diagnostic coverage and specialized cutting power: testers support electrical checks, while the saws and cutting tools address particular installation jobs. No single item replaces a complete, correctly rated electrical test kit or suits every site task. Read on for the full comparison and guidance on matching each tool to your work.

Key Takeaways
- The 2226-20 earns the leading spot for breadth: it combines non-contact voltage detection with GFCI receptacle testing, though it is not a substitute for a multimeter.
- The clamp meters serve different needs: the 2235-20 is the more clearly specified choice for work up to 400 amps, while the 2237-20 is a separate clamp-meter option whose specifications should be checked against the job.
- Electrical diagnostics and material cutting are distinct buying decisions: the circuit breaker finder targets circuit identification, while the oscillating tool, HACKZALL, cut-off tool, and nibbler suit different cutting tasks.
- M12 tools favor compact jobsite handling: the 2426-20, 2420-20, and 2522-20 can suit lighter or more confined work, but buyers need to account for the separate battery and charger requirement.
- The M18 FUEL 10-Gauge Nibbler has the narrowest role: it is aimed at sheet-metal cutting, so its larger platform and specialized purpose make less sense as a general first purchase.

Milwaukee 2226-20 Non-Contact Voltage Detector and GFCI Receptacle Tester
For electricians who need to check outlets as well as spot live conductors, the 2226-20 combines two useful testing jobs in one kit. Its non-contact detector covers 50–1000V AC, while the receptacle tester checks wiring and GFCI protection with visual and audible indicators. That makes it a more targeted choice for installation and troubleshooting work than the Milwaukee 2235-20 Clamp Meter, which measures current, voltage, and resistance but is not described as including a GFCI outlet test. The tradeoff is specialization: this kit does not provide the clamp meter’s broader electrical measurements, and the detector’s stated range begins at 50V AC. Choose it for frequent outlet verification; skip it if one meter for current and voltage measurements matters more.
Pros:- Pairs non-contact voltage detection with a GFCI receptacle tester
- Checks outlet wiring and ground-fault protection
- Uses both visual and audible indicators
- Specified for residential, commercial, and industrial use
Cons:- The stated voltage detection range begins at 50V AC
- Does not provide the current, resistance, and continuity measurements offered by the 2235-20 Clamp Meter
Best for: Residential electricians and service technicians who regularly verify outlet wiring and GFCI protection alongside checking for AC voltage.
Not ideal for: Electricians seeking one instrument for current, voltage, resistance, and continuity measurements; the 2235-20 Clamp Meter covers more measurement tasks.
- Model:2226-20
- Voltage detection range:50–1000V AC
- Test functions:Non-contact voltage detection and GFCI receptacle testing
- Indicators:LED, visual, and audible

- Color:Red/Black
- Number of items:1
Our verdict“Choose the 2226-20 when outlet and GFCI checks are routine; pick a clamp meter instead when broader measurements take priority.”
Milwaukee 2235-20 400 Amp Clamp Meter
The 2235-20 is the lineup’s practical general-purpose clamp meter: it measures AC current to 400A, AC/DC voltage to 600V, resistance, and continuity, with True-RMS readings for varied electrical loads. A backlit display and built-in work light support checks in dim panels, while the included test leads let it handle more than clamp-only measurements. Compared with the Milwaukee 2237-20 Clamp Meter, it has a smaller 1.0-inch jaw and a lower current ceiling, so it is less suited to larger or bundled conductors. In return, its stated capabilities cover many routine service checks without the 2237-20’s broader measurement range. The main compromise is reach: the jaw opening can limit access around crowded conductors, and this model does not include automatic calibration.
Pros:- Measures AC current, AC/DC voltage, resistance, and continuity
- True-RMS readings support measurement across varied loads
- Backlit display and built-in LED work light aid dim-panel work
- Includes test leads and two AAA batteries
Cons:- The 1.0-inch jaw may be restrictive around larger or bundled conductors
- Current measurement is limited to 400A, below the 2237-20’s 600A range
- Automatic calibration is not included
Best for: Electricians doing routine residential and light commercial diagnostics who want clamp, voltage, resistance, and continuity functions in one meter.
Not ideal for: Technicians who frequently clamp larger or bundled conductors or need readings above 400A; the 2237-20 offers a wider jaw and higher current range.
- Model:2235-20
- AC current:Up to 400A
- AC/DC voltage:Up to 600V
- Resistance:Up to 4,000 ohms
- True-RMS:Yes
- Jaw size:1.0 inch

- Display:Black on white with backlight
- Power:2 AAA batteries
Our verdict“Choose the 2235-20 for routine electrical measurements, but step up to the 2237-20 if jaw clearance and higher current capacity matter.”
Milwaukee 2426-20 M12 12V Cordless Oscillating Multi-Tool, Tool Only
For electricians adapting boxes, trimming materials, or sanding in tight spots, the 2426-20 offers several tasks in one compact cordless tool. Its 12 speed settings span 5,000–20,000 OPM, giving the operator room to adjust the action for cutting, scraping, sanding, or grinding. The universal adapter also helps broaden accessory choices beyond the supplied wood blade and sanding pieces. Compared with the Milwaukee 2420-20 M12 HACKZALL, this multi-tool is better suited to controlled, close-up work and surface finishing, while the HACKZALL is the more direct choice for reciprocating cuts. The limitation is power availability: this is a tool-only listing, so buyers need a compatible M12 battery and charger, and runtime depends on the battery selected. It is a versatile add-on, not a substitute for a dedicated cutter on sustained heavy work.
Pros:- Handles cutting, grinding, sanding, trimming, and scraping
- Offers 12 speed settings from 5,000 to 20,000 OPM
- Universal adapter supports most competing accessories
- Compact 1.63-pound tool weight suits close-up work
Cons:- Battery and charger are sold separately
- Runtime depends on the separately purchased battery
- A multi-tool is less suited than a dedicated saw to sustained reciprocating cuts
Best for: Electricians who need a compact tool for careful cutouts, trimming, scraping, and sanding during installation or retrofit work.
Not ideal for: Buyers without an M12 battery and charger, or crews focused on sustained reciprocating cuts better handled by the 2420-20 HACKZALL.
- Voltage:12V
- Speed settings:12
- Speed range:5,000–20,000 OPM
- Tool weight:1.63 lbs
- Length:10-1/4 inches

- Included accessories:Universal adapter, wood cutting blade, sanding pad, five assorted sanding sheets
- Power source:Cordless electric
Our verdict“Pick the 2426-20 for varied, precise finishing and cutout tasks if you already have M12 batteries; choose the HACKZALL for saw-focused work.”
Milwaukee Electric Circuit Breaker Finder with LED
When the job is to match a receptacle or circuit to its breaker, this transmitter-and-receiver kit is more purpose-built than either clamp meter in this roundup. It is designed for 120V electrical panels, and the receiver’s LED helps make the panel easier to see while identifying the target breaker. That focused function can save time during residential and commercial circuit tracing, but it does not replace a meter: the Milwaukee 2235-20 Clamp Meter measures current, voltage, resistance, and continuity, while this finder is for tracing circuits. Its stated operating voltage is 120V, which narrows its usefulness compared with the voltage detector in the 2226-20 kit. Choose it for breaker identification on compatible systems; skip it if you need a general electrical diagnostic tool or must work outside its stated voltage compatibility.
Pros:- Includes both a transmitter and receiver for circuit identification
- LED improves visibility while working at a panel
- Designed to help locate the correct breaker
- Listed for residential and commercial use
Cons:- Compatibility is specified for 120V electrical panels
- Circuit tracing does not replace the measurement functions of a clamp meter
Best for: Electricians and maintenance technicians tracing circuits in compatible 120V residential or commercial panels.
Not ideal for: Technicians who need to measure current, voltage, resistance, or continuity, or who work on systems outside the stated 120V compatibility.
- Model:2222-20
- Minimum operating voltage:120 volts
- Compatible devices:120V electrical panels
- Included components:Transmitter and receiver
- Dimensions:10 x 6 x 2 inches
- Color:Grey
- Standards:UL, CE, IEC 61010-1
Our verdict“Choose this finder for locating breakers on compatible 120V circuits, not as a replacement for the 2235-20’s diagnostic measurements.”
Milwaukee 2237-20 Clamp Meter
The 2237-20 is the stronger pick for conductors that challenge smaller clamp meters: its 1.3-inch jaw and thin profile help it fit around larger or bundled wires, and its current range reaches 600A AC/DC. It also adds non-contact voltage detection, frequency, capacitance, resistance, and continuity functions, making it more measurement-flexible than the Milwaukee 2235-20 400 Amp Clamp Meter. The white-on-black display and LED work light are useful in dim work areas, while True-RMS supports readings across varied loads. That broader range does not mean it suits every job: it is still limited to 600A and 600V, and its larger jaw may be unnecessary for routine measurements on smaller conductors. Pick it when access and measurement headroom matter more than keeping to the 2235-20’s simpler specification set.
Pros:- 1.3-inch jaw and thin profile accommodate larger or bundled conductors
- Measures AC/DC current and voltage up to 600A and 600V
- Includes non-contact voltage detection, frequency, capacitance, resistance, and continuity
- High-contrast display, LED work light, and True-RMS measurement
Cons:- Current and voltage ranges stop at 600A and 600V
- The wider jaw may be unnecessary for work focused on smaller conductors
Best for: Electricians who regularly measure larger or bundled conductors and want a clamp meter with a wider jaw and multiple diagnostic functions.
Not ideal for: Technicians who work mostly on smaller conductors and need only routine readings; the 2235-20 covers core measurements with a smaller jaw.
- Model:2237-20
- Jaw opening:1.3 in (33 mm)
- Current range:0–600A AC/DC
- Voltage range:0–600V AC/DC
- True-RMS:Yes
- Frequency measurement:Yes
- Resistance measurement:Up to 6 kΩ
- Display:White-on-black high-contrast LCD
- Battery and warranty:2 x AA batteries included; 5-year warranty
Our verdict“Choose the 2237-20 for greater jaw clearance and expanded measurements; the 2235-20 is a better fit for routine work with smaller conductors.”
Milwaukee 2420-20 M12 12-Volt Cordless HACKZALL Reciprocating Saw (Tool Only)
For electricians who need to trim conduit, cut small framing sections, or handle quick demolition in tight spaces, the 2420-20 HACKZALL is the most compact saw in this group. At 2.1 pounds, it is easier to maneuver overhead than the M18 FUEL 10-Gauge Nibbler, which is built for sheet-metal cutting and weighs considerably more. Its variable-speed trigger gives you a way to ease into cuts, while compatibility with HACKZALL- and SAWZALL-style blades makes blade choice flexible. The tradeoff is its brushed motor, rather than the brushless design in the nibbler and 2522-20 cut-off tool, and this is a bare tool with no battery or charger listed. Choose it for portable rough cutting, not sustained sheet-metal work.
Pros:- Light 2.1-pound body supports overhead and confined-space cuts
- Accepts both HACKZALL- and SAWZALL-style blades
- Variable-speed trigger helps control starts and cut pace
- Battery fuel gauge indicates remaining runtime
Cons:- Brushed motor differs from the brushless motors in the 2522-20 and M18 FUEL nibbler
- Bare tool; battery and charger are not listed as included
Best for: Electricians who already own M12 batteries and need a light saw for occasional conduit cuts, access openings, or compact demolition.
Not ideal for: Crews making frequent, long cuts in sheet metal or buyers without M12 batteries who want a ready-to-use kit.
- Model:2420-20
- Power source:Cordless
- Voltage:12 volts
- Motor:Brushed
- Blade compatibility:HACKZALL- and SAWZALL-style blades
- Weight:2.1 pounds
- Dimensions:10 × 6 × 2.25 inches
- Included components:Bare tool
- Warranty:5-year limited warranty
Our verdict“Choose this compact HACKZALL for light, varied cutting in tight electrical work areas if you already have M12 batteries.”
Milwaukee 2522-20 M12 FUEL Cut-Off Tool, 12V, Bare Tool
The 2522-20 M12 FUEL Cut-Off Tool is the focused choice when a reciprocating saw is too bulky for a small cut and a nibbler is more tool than the job needs. Its reversible blade rotation gives electricians control over the direction of debris and cutting action, while the ergonomic grip is suited to one-handed positioning. The brushless motor and REDLINK PLUS intelligence add overload protection and performance management, features the brushed 2420-20 HACKZALL does not provide. That does not make this a substitute for the HACKZALL’s wider blade flexibility or the M18 FUEL nibbler’s stated capacity for 10-gauge mild steel. The cut-off tool’s role is compact, controlled cutting; its key limitation is that it arrives as a bare tool, with no battery listed.
Pros:- Brushless motor is designed for power and extended motor life
- Reversible blade rotation offers control over cutting direction
- REDLINK PLUS intelligence provides overload protection
- Ergonomic grip supports one-handed operation
Cons:- Battery is not listed as included
- Its cut-off format is less versatile than the 2420-20’s compatibility with two blade styles
Best for: Electricians with M12 batteries who need a compact tool for controlled, one-handed cutting in confined work areas.
Not ideal for: Buyers seeking a reciprocating saw for varied blade-based cuts or a dedicated tool for repeated cuts through 10-gauge mild steel.
- Model:2522-20
- Power source:Battery powered
- Voltage:12 volts
- Motor:Brushless
- Maximum rotational speed:20,000 rpm
- Dimensions:8.9 × 6.9 × 4.5 inches
- Weight:1.2 kg
- Included components:Unit and instruction guide
Our verdict“Pick the 2522-20 for compact, controlled one-handed cuts if you have an M12 battery and do not need a reciprocating saw or sheet-metal nibbler.”
Milwaukee M18 FUEL 10-Gauge Nibbler (Bare Tool)
When an electrical installation calls for repeated, controlled cuts in sheet metal, the M18 FUEL 10-Gauge Nibbler is the most specialized option here. Its stated capacity covers 10-gauge mild steel, and the brushless motor, variable-speed controls, and 360-degree tool-free die-holder rotation are aimed at maintaining control through turns and changing cut directions. The included chip collection bag also helps contain the waste created by nibbling, unlike the 2420-20 HACKZALL, which is a more general-purpose saw for rough cuts. Specialization brings a real cost in handling: at 9.74 pounds, this is much heavier than either M12 cutting tool, and it is a bare tool with no battery listed. It suits planned sheet-metal tasks better than quick, overhead trimming.
Pros:- Rated to cut 10-gauge mild steel
- Variable-speed controls support managed cutting through turns
- Tool-free 360-degree die-holder rotation adjusts cutting orientation
- Chip collection bag is included
Cons:- At 9.74 pounds, it is substantially heavier than the M12 cutting tools in this roundup
- Bare tool; battery is not listed as included
Best for: Electricians who regularly cut 10-gauge mild-steel panels or enclosures and already use M18 batteries.
Not ideal for: Electricians prioritizing lightweight overhead work, occasional small cuts, or a cutting tool for mixed materials and tasks.
- Model:3476-20
- Power source:Battery powered
- Voltage:18 volts
- Motor:POWERSTATE brushless
- Cutting capacity:10-gauge mild steel
- Weight:9.74 pounds
- Dimensions:14 × 5 × 6 inches
- Included components:Chip collection bag
- Package quantity:1
Our verdict“Choose this M18 nibbler for frequent 10-gauge mild-steel cutting where controlled turns matter more than low weight.”
How We Picked
I ranked these eight options by how directly they support common electrical work, how broad their usefulness is across tasks, and how clearly a buyer can match each tool to a job. Diagnostic tools lead because safe circuit identification and measurement are foundational tasks; the 2226-20 ranks first for combining two checks, while clamp meters follow for current measurement. I placed the circuit breaker finder according to its focused role rather than treating it as a substitute for electrical testing.
For cutting tools, I weighed portability, task specificity, and platform fit. The M12 oscillating tool and HACKZALL have wider potential usefulness across installation and service work than the more specialized cut-off tool and sheet-metal nibbler. I also accounted for kit requirements: bare tools require a compatible battery and charger, and none of these picks should be selected without checking its specifications, accessories, and suitability for the work and electrical environment.

Factors to Consider When Choosing Milwaukee Power Tools For Electricians Guide 10
Choosing among these tools starts with the task, not the platform label. I would separate electrical measurement from material removal, then check what your existing kit already covers. These buying factors help prevent paying for a specialized tool that rarely leaves the van or relying on a device that cannot perform the required test.
Prioritize safety ratings and work procedures
Electrical work places more weight on instrument suitability than on convenience features. Confirm the tool’s stated electrical ratings and intended use for the environment where it will be used, and inspect it according to its manual and your workplace procedures. Do not treat a voltage detector, breaker finder, or receptacle tester as interchangeable with a meter. Nor should any device replace de-energizing and verification steps required for the work. Buyers should also check that leads, probes, and accessories are compatible and in sound condition. When a task falls outside the tool’s stated capability, use a properly rated alternative or consult qualified guidance.
Frequently Asked Questions
Can the 2226-20 replace a multimeter for electrical service work?
No. The 2226-20 combines non-contact voltage detection and GFCI receptacle testing, but that does not make it a full multimeter. Buyers who need readings such as voltage values, resistance, or continuity should verify those requirements and select a meter designed for them. Use each instrument only for its stated functions and ratings. A combination device may reduce the number of separate tools for basic checks, but it does not remove the need for other test equipment when the job calls for it.
Which clamp meter should I choose: the 2235-20 or the 2237-20?
Start by comparing the exact functions and ratings in the manufacturer’s documentation for both model numbers. The 2235-20 is identified as a 400-amp clamp meter, but that headline rating alone does not establish which meter suits your full workload. Check the required measurement types, working range, safety rating, and conductor access for your jobs. If your needs are occasional or narrow, avoid choosing based only on a larger number. Select the meter whose documented capabilities match the work you actually perform.
Should I buy an M12 cutting tool or the M18 FUEL nibbler first?
That depends on what you cut most often. The M12 oscillating tool, HACKZALL, and cut-off tool each address different kinds of compact cutting tasks, while the M18 FUEL nibbler is specifically aimed at sheet metal. If service work brings varied materials and tight access, an M12 tool may fill a broader role. If sheet-metal cutting is frequent and central to your work, the nibbler’s focused purpose may justify its place in the kit. Check platform ownership, material requirements, and tool limits before deciding.
Are these Milwaukee tools ready to use if I do not own their batteries?
Several listed cordless tools are explicitly sold as tool-only or bare-tool products, so a compatible battery and charger may be needed separately. The cordless options span M12 and M18 platforms, and batteries are not interchangeable across those platforms. Check the package contents and exact model details before ordering. If you are starting without batteries, account for the complete setup rather than assuming the tool listing includes everything needed to operate it. If you already own compatible batteries, confirm their condition and suitability for the task.
Is a circuit breaker finder a replacement for testing a circuit?
No. A breaker finder is intended to help identify the breaker associated with a circuit; it does not replace a properly rated instrument or required safety checks. Circuit identification and confirming electrical conditions are separate tasks. Follow the finder’s instructions and your workplace procedures, then use the correct test method for the work being performed. Do not rely on a breaker label or finder result alone when safety depends on verifying the circuit state. Choose test equipment based on the specific measurement or verification required.
Conclusion
Best overall: I would choose the 2226-20 for buyers who want two useful checks in one device. Best value: the 2426-20 M12 oscillating tool is the broader cutting pick for users who already own compatible M12 batteries and need controlled, varied cuts. Best premium: the M18 FUEL 10-Gauge Nibbler makes the most sense for electricians with recurring sheet-metal work, not as a general-purpose first tool. Best for beginners: the 2226-20 offers an approachable starting point for basic voltage and receptacle checks, while still leaving room for a properly rated meter as skills and tasks expand. For current measurement, compare the documented capabilities of the 2235-20 and 2237-20; for circuit identification, choose the breaker finder; for compact cutting, pick among the M12 tools by material and cut type. Match the tool to the job, verify ratings and package contents, and build around your existing battery platform.
