Milwaukee 1" High Torque Impact Wrench w/ ONE-KEY™

The Milwaukee 1" High Torque Impact Wrench w/ ONE-KEY™ (Model 2867-20) is an ambitious attempt to bring the power and convenience of cordless tools to the realm of heavy-duty applications. As a professional who often needs reliable and powerful tools for demanding tasks, I had high expectations for this impact wrench. After extensive use, I found that it has both notable strengths and some significant shortcomings.

Design and Build Quality

The first thing I noticed about this impact wrench is its robust build. The tool is constructed from reinforced nylon, giving it a sturdy feel while keeping the weight manageable at 10.64 lbs. The compact design, measuring 10.9 inches in length and 9.69 inches in height, makes it easier to maneuver in tight spaces compared to its bulkier pneumatic counterparts. The integrated LED light is a thoughtful addition, providing ample illumination in poorly lit work areas. The built-in lanyard loop adds a layer of safety, especially when working at heights.

Performance

Milwaukee advertises this tool with up to 1,800 ft-lbs of nut-busting torque and 1,500 ft-lbs of fastening torque. While these numbers are impressive on paper, my real-world experience revealed a more nuanced picture.

Torque and Power

In lighter applications, such as removing or fastening bolts on commercial trucks and general repair work, the impact wrench performed admirably. It effortlessly handled tasks like loosening yoke nuts and head bolts, tasks that typically demand substantial torque. However, when it came to more challenging applications, like removing semi-truck wheel nuts that had been on for a long time, the tool struggled. Despite using a fully charged Milwaukee M18 REDLITHIUM High Output HD12.0 battery, it sometimes failed to deliver the promised torque, requiring additional effort or alternative tools to complete the job.

Battery Performance and Overheating

Battery life is another critical factor for any cordless tool, and this impact wrench is no exception. Using higher capacity batteries like the 12.0Ah significantly improves performance, but the tool is quite demanding on the battery. During extended use, especially on heavy-duty tasks, the impact wrench tends to overheat. This overheating issue necessitates breaks in between tasks, which can be a significant drawback when working on time-sensitive projects. The absence of a battery strap to secure the battery can also lead to it rattling loose under high-torque applications, which is another inconvenience.

ONE-KEY™ Technology

The inclusion of ONE-KEY™ technology is a double-edged sword. On the one hand, it offers customizable tracking and management, allowing for tailored power settings and tool tracking via a smartphone app. This feature can be incredibly useful for fleet management and ensuring the tool is always operating at its optimal settings. On the other hand, the complexity of setting up and managing this feature might be off-putting for those who prefer straightforward, plug-and-play tools. For seasoned professionals who may not see the need for such digital integration, this could be seen as an unnecessary complication.

Usability and Comfort

Despite its power limitations in some scenarios, the impact wrench is quite user-friendly. The 4-mode drive control allows for adjustable power settings, making it versatile for various tasks. The ergonomic design and relatively lightweight build reduce user fatigue, even during prolonged use. However, the tool’s tendency to pulse or slip during free spin can be irritating and potentially hazardous, especially when working in confined spaces.

Versatility and Application

While the impact wrench excels in certain areas, it’s essential to recognize its limitations. It’s not a one-size-fits-all solution and should be viewed as a complementary tool rather than a replacement for more traditional pneumatic impacts. For quick jobs or when working in remote locations without access to air compressors, this tool is a time-saver. However, for more demanding applications that require consistent high torque, traditional air-powered tools still hold an edge.

Conclusion

In conclusion, the Milwaukee 1" High Torque Impact Wrench w/ ONE-KEY™ is a mixed bag. It brings the convenience and mobility of cordless tools to heavy-duty applications, but it falls short of delivering the consistent power that its specifications promise. Its build quality, ergonomic design, and innovative features like ONE-KEY™ technology are commendable, making it a useful addition to a professional’s toolkit. However, its performance inconsistencies and tendency to overheat during extended use are significant drawbacks.

Would I recommend this tool? It depends on your specific needs. If you frequently work in remote locations where access to air compressors is limited, and you need a portable, high-torque solution for moderate tasks, this impact wrench can be a valuable asset. However, if your work demands consistent, high-torque performance for heavy-duty applications, you might be better served sticking with traditional pneumatic tools or waiting for an updated model that addresses these performance issues.

Ultimately, the Milwaukee 1" High Torque Impact Wrench w/ ONE-KEY™ has its place, but it’s not the all-encompassing solution that some might hope for. It’s a specialized tool with clear strengths and notable weaknesses, making it essential to consider your specific requirements before making an investment.
