Milwaukee Cordless 2-Speed Grease Gun

Navigating the world of grease guns can be a bit daunting, but the Milwaukee Cordless 2-Speed Grease Gun, model 2646-20, has certainly made a mark with its impressive features and robust design. After putting this tool through its paces, I have a comprehensive understanding of both its strengths and its shortcomings.

Design and Build Quality

The first thing that struck me about this grease gun is its solid construction. With a weight of 7.6 lbs, it feels substantial in hand, but not overly cumbersome. The stand-up design is practical, allowing the tool to stay upright without tipping over easily, which is a huge plus when working in the field. The inclusion of a shoulder strap capability is thoughtful, although the strap itself is not included, which could have been an added convenience.

One notable feature is the 48-inch flexible hose. This length is incredibly useful for reaching those hard-to-access fittings, though it does require careful handling to prevent dragging the tip through dirt or grime. The hose is durable and flexible, maintaining its shape well and resisting kinks, which is crucial for maintaining consistent grease flow.

Performance

Performance-wise, this grease gun is quite the powerhouse. It boasts a maximum operating pressure of 10,000 PSI, which is more than sufficient for most applications. The two-speed design is a standout feature, allowing users to switch between maximum pressure and maximum flow rate depending on the task at hand. This versatility makes it suitable for a variety of greasing needs, from heavy machinery to more delicate equipment.

One of the most useful features is the pre-set grease counter. This allows for precise dispensing, ensuring you don't over-grease or under-grease your fittings. Coupled with the LED light, which illuminates the work area, this grease gun is designed with user convenience in mind. This is particularly handy in low-light conditions or when working in tight, dark spaces.

Usability

The tool's usability is generally excellent, but it does come with a learning curve. Loading the grease cartridges can be tricky at first. The plunger rod, which has markings for grease level indication, is initially stiff and can be difficult to pull back. Priming the grease gun also requires some patience, and it occasionally loses prime, necessitating a bit of manual intervention to get it going again. However, once you get past these initial hurdles, the tool operates smoothly.

The lock-on/lock-off trigger is another feature that enhances usability. It allows for continuous operation without the need to keep the trigger pressed, reducing hand fatigue during extended use. However, the trigger design could be improved as it sometimes feels a bit too sensitive, especially when working in tight spaces where accidental activation is a risk.

Battery Life

Battery life is one area where this grease gun truly excels. Powered by the M18™ REDLITHIUM™ battery system, it can run through up to 10 grease cartridges on a single charge. This is particularly impressive and a significant improvement over many other cordless grease guns on the market. The ability to use the same batteries across other Milwaukee tools is an added bonus, simplifying battery management for those already invested in the M18 ecosystem.

Drawbacks

Despite its many strengths, the Milwaukee grease gun is not without its flaws. The most significant issue is the priming process, which can be frustrating and time-consuming. This is a common problem with many grease guns, but it’s particularly pronounced here. Additionally, the tool's weight, while indicative of its robust build, can be a drawback for those needing to use it in awkward positions or for extended periods.

Another minor annoyance is the coupler, which can sometimes get stuck on zerk fittings. While this can be mitigated by loosening the tip grip or using a different coupler, it’s an extra step that shouldn't be necessary for a tool at this price point.

Durability and Reliability

In terms of durability, the Milwaukee grease gun stands out. It’s built to withstand heavy use and rough conditions, which is essential for a tool that’s likely to see a lot of fieldwork. The low center-of-gravity design helps prevent tipping and makes it easier to handle, even in less-than-ideal conditions. The 5-year limited warranty also provides peace of mind, ensuring that any manufacturing defects will be addressed.

Conclusion

After thoroughly evaluating the Milwaukee Cordless 2-Speed Grease Gun, I can confidently say that it’s a solid investment for those who need a reliable, high-performing grease gun. Its robust build, powerful performance, and user-friendly features make it well-suited for a variety of applications, from farm equipment to industrial machinery.

While it does have some drawbacks, particularly with the priming process and weight, these are relatively minor issues that can be managed with a bit of practice and adjustment. The impressive battery life and versatility of the two-speed design more than make up for these shortcomings.

In summary, I would recommend the Milwaukee Cordless 2-Speed Grease Gun to anyone in need of a dependable, efficient, and powerful greasing solution. Whether you’re a professional mechanic, a farmer, or someone who regularly maintains heavy equipment, this tool is likely to make your work easier and more efficient.
