Milwaukee 750 MCM Crimper Kit

Milwaukee tools have been a constant companion in my toolkit, and their 750 MCM Crimper Kit (model 2779-22) is no different. This crimper, designed to handle #8 - 750 MCM copper and aluminum connectors, stands out for its blend of innovation and practicality. Over the past few weeks, I’ve had the chance to put it through its paces, and here's my in-depth take on it.

Design and Build Quality

At first glance, the Crimper is visually impressive and feels exceptionally well-built. Weighing in at 11.3 lbs, it strikes a balance between being robust yet manageable. The lightweight and balanced design are immediately noticeable, making it easier to handle for extended periods. The tool's 350-degree rotating head is a game changer for accessibility, allowing you to maneuver it into tight spots effortlessly. This rotational capability is particularly useful in cramped electrical boxes or when working in confined spaces.

The crimper's overall design screams durability. The machining is precise, and the components fit together flawlessly. One feature that stands out is the click-lock system for the dies, which ensures they stay securely in place during use.

Performance and Usability

Performance-wise, the Milwaukee crimper doesn’t disappoint. One of its standout features is the Predictive Force Monitoring (PFM) system, which guarantees consistent pressure throughout the crimping process. This ensures that every crimp is reliable and up to standard. I appreciated the Auto-complete function that guarantees full pressure is achieved before completing the crimp. This feature, combined with the pre-crimp battery check, means you won’t find yourself stuck halfway through a job because of insufficient power.

Speaking of power, the kit comes with both a 5.0 Ah and a 9.0 Ah battery, providing ample runtime for most tasks. The battery setup is straightforward, and the included charger works efficiently. The lithium-ion batteries are part of Milwaukee’s M18 system, meaning they are interchangeable with other tools in the lineup, which adds a layer of convenience.

ONE-KEY Technology

The integration of ONE-KEY technology is another feather in the cap for this tool. This feature allows you to track and manage the tool's data through a smartphone app. While this might seem like a gimmick to some, it’s incredibly useful for professionals who need to keep tabs on their equipment. The app provides not just the location of the tool but also diagnostic information and usage history, which can be crucial for maintenance and ensuring the tool’s longevity.

Crimping Efficiency

In practical use, the crimper performs exceptionally well. The force applied during crimping is substantial, and the resulting connections are rock solid. This tool dramatically reduces the physical effort required compared to manual crimpers. The fact that it holds the lug and crimp together seamlessly with one hand free to manage the wire is a significant upgrade. This efficiency translates into quicker job completion times, which is always a plus in the field.

Limitations and Issues

However, no tool is without its drawbacks. One minor gripe is that the crimping dies are sold separately, which can be a bit of a hassle and an additional expense. It would have been more convenient if the kit included a basic set of dies to get started.

A more pressing issue is the reliability concerns some users have reported. While my experience has been largely positive, there are instances where the tool failed to operate correctly after a few uses. This inconsistency can be worrying, especially considering the high price point. Having to send the tool back for repair or replacement can disrupt work schedules significantly.

Comparison to Competitors

In comparison to other crimpers like Burndy, the Milwaukee 750 MCM Crimper holds its own. It matches or exceeds the performance of similar tools while offering the added benefits of the ONE-KEY system and predictive force monitoring. However, it is slightly bulkier, which might be a consideration for those who prioritize a more compact design.

Final Thoughts

Overall, the Milwaukee 750 MCM Crimper Kit is a high-quality, high-performance tool that brings several innovative features to the table. Its ease of use, combined with robust build quality and advanced technology, makes it a valuable addition to any professional electrician's arsenal. The rotating head, predictive force monitoring, and ONE-KEY technology are standout features that elevate this tool above many of its competitors.

Would I recommend the Milwaukee 750 MCM Crimper Kit? Absolutely. Despite some concerns about reliability, the positive aspects far outweigh the negatives. Its efficiency, ease of use, and advanced technology make it a worthy investment for professionals who need a dependable and powerful crimper for heavy-duty electrical work. For those willing to invest in a tool that promises precision and longevity, the Milwaukee 750 MCM Crimper Kit is a solid choice.
