The Milwaukee 48-22-3078 7-in-1 High-Leverage Combination Pliers is a multi-function electrical hand tool built for wire preparation and termination work. This is a combination pliers designed for electrical installation, wire stripping, wire cutting, twisting, and crimping. Model Number: 48-22-3078. If you do service work, rough-in, panel work, or outlet and switch installs, this tool is meant to cut down the number of separate tools you carry for common wire tasks.

The main draw here is productivity. Milwaukee combines wide jaw pliers for grabbing and twisting wire, a crimper for insulated and non-insulated terminals, a wire stripper, wire cutter, reamer, and bolt cutter into one layout. For real jobsite use, that means less pocket swapping and less back-and-forth to the bag. The stripper handles 8 to 18 AWG solid wire and 10 to 20 AWG stranded wire, which covers a broad range of the branch-circuit and device work electricians deal with every day.

The cutting and prep features are practical, not just there for the box copy. The wire cutter is rated to cut up to (4) 12 AWG wires, so it is built for actual electrical work rather than light trimming only. The bolt cutter handles #6 and #8 bolts, which is useful when you need to shorten common hardware on the spot instead of hunting down a separate cutter. Milwaukee also includes a loop maker, which helps speed up clean conductor loops for device terminations.

For conduit work and box prep, the built-in reamer covers 1/2 in. through 1 in. conduit. That is the kind of feature that saves time because you can deburr without stopping to switch tools. The wide jaw design also helps with grabbing and twisting conductors, especially when you need a little more bite and control than a standard lineman-style nose gives you.

Milwaukee built these electrical pliers with high-leverage handles and a comfort grip, and that matters more than it sounds on repetitive work. Easier cutting and crimping means less hand fatigue through a full day of device installs, trim-out, or service calls. The swing-lock design is another smart touch because it allows faster one-handed operation when the other hand is holding wire, a box, or a fixture. There is also a tether-ready lanyard hole for work where drop prevention matters.

At 9 in. long and about 0.75 lb, the Milwaukee 48-22-3078 7-in-1 High-Leverage Combination Pliers lands in a good middle ground. It is large enough to provide useful leverage, but still compact enough for pouch carry and work inside boxes and tight electrical spaces. The steel construction is what you want in a tool that is expected to cut, strip, twist, and crimp repeatedly.

This tool makes the most sense for electricians, maintenance techs, low-voltage installers, and serious DIY users doing real electrical work. If your day involves cutting conductors, stripping insulation, twisting wires together, and crimping terminals over and over, this pliers tool earns its spot fast. If you only need a basic pair of general-purpose pliers, it may be more tool than you need. But for electrical work, the built-in functions are the whole point.

Milwaukee 48-22-3078 7-in-1 High-Leverage Combination Pliers is the kind of electrical hand tool that actually earns pocket space

If you do enough wire work to get annoyed switching between stripper, crimper, pliers, and reamer, this one simplifies the routine in a way that makes sense.

• Who it's for: Electricians, maintenance techs, and serious DIY users who regularly strip, twist, cut, and crimp conductors.
• Why it stands out: The function mix is right for real electrical work, and the high-leverage design helps it feel like a working tool instead of a compromise tool.
• Worth knowing: This is still a specialized electrical pliers, not a general all-purpose plier for every trade. If you are not doing wire prep often, you may not use all seven functions.

• What wire sizes can it strip? It strips 8 to 18 AWG solid wire and 10 to 20 AWG stranded wire.
• Can it crimp insulated and non-insulated terminals? Yes. The built-in crimper is designed for both insulated and non-insulated terminals.
• Does it ream conduit? Yes. The built-in reamer is designed for 1/2 in. through 1 in. conduit.
• What bolts can it cut? It cuts #6 and #8 bolts.
