Milwaukee M18 Force Logic 750 MCM Dieless Crimper

The Milwaukee M18 Force Logic 750 MCM Dieless Crimper recently put on a crimping clinic and displayed the company’s knack for innovation. An inline design and proprietary Auto Distance Control makes it the lightest battery-powered 750 MCM crimper on the market. Our crew at G&G Electric gave it a test run wiring up large cables at a regional airport. The job site provided the perfect proving ground for the Milwaukee 2877-22.

Need a Lift?

The airport job required working up in a lift, wrestling stiff cables into a shallow box, and crimping in tight spaces. In other words—perfect examples of the advantages of the remarkably light and maneuverable Milwaukee M18 Force Logic 750 MCM dieless crimper.

The benefits of a battery-powered crimper of any kind over the hydraulic or manual pump versions that we used for so many years should seem obvious. There’s also a clear advantage when using a dieless crimper. For those new to crimping: someone could have forgotten the dies in the truck—or worse, back at the shop! That’s incredibly inconvenient when you find yourself up on a lift. And there’s no tethering dies when working at height, so inherent convenience and safety features come along with dieless crimpers.

The Milwaukee 2877-22 Grip Style

Of course, the Milwaukee M18 750 MCM dieless crimper has dieless competitors. Most use a pistol-grip style much like this model’s (die-d) predecessor we reviewed a few years ago.

The barrel-grip inline design shaves the weight down to 9 pounds from 11.3—and that comes before adding dies. Even DeWalt’s pistol-grip dieless crimper comes in at 11.2 pounds. We were very grateful for the weight reduction as we contorted ourselves and the cables to get proper crimps on the barrels!

Sometimes. it took multiple hands to get everything situated properly on this job. Not a factor of the tool, we simply had some very tight locations in which to work.

The inline design also makes the Milwaukee 2877-22 dextrous in tight, shallow spaces. Simply put the barrel in the clevis for the first crimp or open the access latch and slip the jaw around the barrel for the second crimp. You can hold the Milwaukee M18 Force Logic 750 MCM dieless crimper out further from your body with less fatigue than the heavier, pistol-grip versions. And the 180° rotating head helps, too.

Crimping With Confidence

There’s no need to adjust the crimper across the size range because its Auto Distance Feature detects and adjusts to provide the appropriate crimp. As you may have seen with other crimpers, the tool will only begin the crimp if the battery has enough power to complete it. And you know it supplied the proper amount of pressure when the green light illuminates.

The Milwaukee M18 750 MCM Dieless Crimper can certainly make crimping heavy cable a one-person job, but we found it much easier with two of us, especially as we became acquainted with the tool. If you don’t have a lot of cable to work with, you may just need a hand wrestling it into place for the proper crimp.


Crimpers often fall among the most expensive power tools on the job. The Milwaukee M18 Force Logic 750 MCM dieless crimper kit is no exception at $4,599. Although it’s the only inline design in the group, here’s a look at some competitors.
