The 8 Best Hydraulic Cable Crimpers
Updated by · How we research
Eight hand-pump and cordless lug crimpers compared by wire range, dies and build quality. The TEMCo TH0005 leads for its 10 AWG to 600 MCM reach. When users buy our independently chosen editorial selections, we may earn commissions to help fund the Wiki.
Tonnage on a crimper's box says little about the joint it makes. What matters is a die that matches the lug and the cable, closing into a clean hex with every strand packed inside the barrel. This guide covers hand-pump and cordless tools for battery banks, welding leads, RV and solar wiring, from small wire to service cable.
Editor's Notes
October 23, 2026, by Ezvid Wiki Editors:
The TEMCo TH0005 moves to the top. It spans more wire sizes than any other hand pump we'd trust, and its owners rarely report a failure. The TEMCo TH0006 joins it as the smaller sibling for battery cables.
We dropped the Milwaukee 2678-22BG, Klein Tools BAT207T144H and Greenlee HK12ID. They are fine utility tools, but they cost thousands and none was in stock at a usable price, so Milwaukee and Greenlee now sit in the special honors. The Goplus 16 Ton is no longer available, the CKE Swaging Tool 680579343953 is a cable-railing swager, and the Yescom 10 Ton was one of a crowd of look-alike 10-ton clones, so we kept just one of those.
Evidence here is thinner than we'd like. Only the TH0006 has been through a published crimping test, so most of this ranking rests on die charts, wire ranges and the cracked heads and loose dies that turn up again and again in owner reports of the cheap clones.
Earlier notes

It was a busy round of updates that transformed these rankings considerably. While our previous list comprised a collection of wallet-friendly choices from lesser-known tool companies, this round of updates found half of those options to be unavailable. As a result, we wound up removing the Chromex Tools 16 Ton, Penson Tool and TMS WL-YQK-300.
We also noticed that the Z ZTDM 16T and Goplus 16 Ton appeared to share virtually the same design, so we removed the former and retained the latter, noting that – although the 16T was a bit more affordable – the 16 Ton seemed to be supported by better user reviews. We also added the CKE Swaging Tool 680579343953 to our list – a compact, budget pick that comes with a set of cable-cutting pliers and a bonus pair of work gloves – but beyond that, we wanted to focus our new additions on top-end options that are suitable for use by professionals.
The Klein Tools BAT207T144H and Milwaukee 2678-22BG are two battery-powered models that earned spots at the top of our list with their automatic convenience. Both options come with a charger and a pair of batteries, but it should be noted that, while the Milwaukee runs on its proprietary line of M18 batteries, the Klein Tools option is powered by 20-volt DeWalt cells — which may provide a bit of extra incentive to purchase, if you’re already invested in the company’s popular line of power tools.
The Greenlee HK12ID is a manual model, but it’s still quite a convenient choice, via the virtue of its dieless design, which allows you to take on conductors as small as #4 AWG and as large as 1,000 kcmil without ever changing hardware. It’s backed by a one-year warranty, which is alright, but coming from a company that’s known for its lifetime guarantees, it also might strike some as lackluster assurance.
If the models on this list are bigger than what you had in mind, you might want to check out our generalized list of cable crimpers, which includes several smaller models.

This tool generally requires a learning curve with significant room for user error. After practice, however, these models will give you professional-quality results. User priorities can vary based upon factors like die strength, weight, price, or how often the tool will be used. While it’s on the pricier end, the Temco TH0005 offers a long warranty and proves to be a high-quality, dependable choice.
Special Honors
Greenlee Greenlee makes the dieless and die-type battery crimpers that utility and industrial electricians use, including the HK12ID, which handles very large copper and aluminum conductors without changing dies. Expect contractor pricing through electrical distributors. greenlee.com
Milwaukee Tool Milwaukee's M18 Force Logic crimpers take U-style dies listed with major lug makers, which matters for inspected work. They are sold as contractor kits through distributors and cost far more than a hand pump. milwaukeetool.com
Match The Die To The Lug, Not The Tonnage
A good one shows a clean, centered hex, strands filling the barrel with none folded back, and no cracks in the lug.
The ton figure printed on a hand crimper is a sales number. Bob Vila notes that hand-pump tools are typically rated from 8 to 16 tons (Bob Vila), and most of them build more force than a battery lug needs. What decides the joint is the die. Each die pair closes to a set hex size for one wire gauge, and using the next size up leaves a loose barrel that can heat under load.
Read the die chart before you buy. A 12 AWG to 2/0 set covers car, boat and most RV battery cables. Solar banks and big inverters often run 4/0, and service-entrance or welding work can need 250 to 600 MCM. Dies stamped in American wire sizes save guesswork; some clones ship metric dies with loose AWG equivalents. Half-size dies help when a lug's barrel is a little oversized for the cable.
Then check every crimp. A good one shows a clean, centered hex, strands filling the barrel with none folded back, and no cracks in the lug. A firm pull should not move it (UL 486A-486B crimping summary).
Copper, Aluminum And Code Work
Copper lugs and cable are the easy case. Aluminum is softer and grows an oxide skin, so aluminum lugs usually come pre-filled with an oxide-inhibiting compound, or you add it before crimping (UL 486A-486B crimping summary). Dies sized for copper can also be wrong for aluminum: some makers tell you to step up one die size for aluminum lugs.
For work an inspector will see, the rules get stricter. Connectors are listed under UL 486A-486B with specific tools and dies, and the connector maker's instructions name them. That is why utility crews buy tools whose dies are listed for Burndy, Ilsco, Panduit and Thomas & Betts lugs, such as Milwaukee's U-style dies (The Power Tool Store). A bargain hand pump is fine for your own battery bank, but for service and panel work use the tool and die the lug maker charts.
Crimp only cable that is disconnected and dead, and cut heavy cable with a proper cutter first.
Hand Pump, Cordless Or Utility Tool
Hand pumps cover most home and vehicle work. They are slow on a long run of lugs and tiring on the big sizes, but they need no battery and little care. Bob Vila suggests purging air from the cylinder now and then and replacing the oil seals when the tool starts to lose pressure (Bob Vila). Store it with the release valve open.
Cordless kits do the pumping for you. They make sense for anyone who crimps dozens of lugs at a time, but most on the market come from young brands with short records, so buy where returns are easy.
Above them sit utility-grade battery tools from Greenlee, Milwaukee and Klein. Dieless heads such as the Greenlee HK12ID crimp from about 6 AWG to 1000 kcmil without swapping dies. They cost thousands, which only makes sense for an electrical contractor or a utility crew.
How we researched this
We compared 25 current crimpers, from bargain hand pumps to utility-grade battery tools, read makers' die charts and specifications, Bob Vila's crimping tool tests and a summary of the UL 486A-486B crimping standard, analyzed owner feedback for broken heads, loose dies and leaks, and checked every brand against U.S. Consumer Product Safety Commission recall records. We found no crimping tool recalls.
Frequently asked questions
Is a hydraulic crimper better than a hammer crimper?
For cables of about 6 gauge and up, yes. A hammer crimper dents one side of the lug, and the result depends on your swing. A hydraulic die closes evenly around the barrel every time.
Do 10-ton and 16-ton ratings matter?
Not much. Most hand pumps have more force than a battery lug needs. The wire range and the die list decide what a tool can do; treat ton ratings on budget tools as sales claims.
Can I crimp aluminum lugs?
Yes, with the right die and an oxide-inhibiting compound. Some tools calibrate dies for copper and tell you to use the next size up for aluminum, so check the manual.
Will these crimp hydraulic hose fittings?
No. Hose crimpers use a different die set and head, sized for hose ferrules. These tools are for electrical lugs and splices.
Can I cut cable with a hydraulic crimper?
No. Use a cable cutter first. Some kits include one, but forcing a crimp head through cable can crack it.
Is a cordless crimper worth it?
If you crimp dozens of lugs at a time, it saves your hands and time. For a battery bank or a few welding leads, a hand pump does the same job for much less.
