DeWalt Cordless Grease Gun

The DeWalt DCGG571B Cordless Grease Gun is a powerhouse in the realm of lubrication tools, and after using it extensively, I can confidently say it's a game-changer for anyone regularly maintaining heavy machinery or vehicles. With its impressive features and robust build, this tool makes what used to be a tedious and messy task into something almost enjoyable.

Performance and Features

One of the standout features of this grease gun is its motor, which delivers up to 10,000 PSI. This kind of pressure is more than sufficient for even the most stubborn grease fittings. In practice, I found that the high-volume pump, capable of delivering up to 5 ounces per minute, made quick work of greasing my old backhoe, which has some challenging and often clogged fittings.

The variable speed trigger is another great feature, allowing me to control the flow of grease precisely. Whether I needed a slow, controlled application or a quick burst, the adjustable speed made it easy to adapt to different fittings and conditions. The 42-inch flexible hose is a thoughtful addition, providing the reach needed to access difficult or awkwardly placed grease fittings without wrestling the tool into position.

Usability

The tool's usability is further enhanced by its built-in LED light. This may seem like a small addition, but when working in low-light conditions or underneath equipment, the bright LED provides much-needed visibility. The integrated no-mar foot design is another subtle yet useful feature, allowing the tool to rest stably on surfaces without causing damage or getting dirty.

One of the minor frustrations I encountered was with the pump filter screen, which is designed to prevent clogging. While this is useful for keeping the grease flow smooth, it can sometimes cause issues if the grease itself is of lower quality or if it's very cold. Removing the screen helped in these situations, but it’s something to be aware of if you’re working in low temperatures or with less-than-premium grease.

Loading and Maintenance

Loading the grease gun and priming the pump is straightforward, thanks to the air-bleeder valve. This feature eliminates air pockets that can disrupt the flow of grease, making the process of changing cartridges almost hassle-free. However, during the initial uses, I did experience some minor issues with air locks when changing tubes. It’s not a deal-breaker, but it can be inconvenient if you’re in the middle of a large job.

The tool's design also includes a shoulder strap, which I found invaluable given the unit's weight. It’s not the lightest tool, but the strap helps distribute the weight and makes it easier to carry around a job site. This is particularly useful if you’re moving between multiple pieces of equipment.

Durability and Build Quality

As with other DeWalt tools, the build quality of this grease gun is excellent. The tool feels sturdy and well-made, capable of withstanding the rigors of regular use. I’ve used it in various weather conditions, and it has performed reliably each time. The three-year factory warranty is a nice peace of mind, although I haven’t had any issues that required me to use it.

Comparisons and Alternatives

While the DeWalt grease gun performs admirably, I did have the opportunity to compare it directly with the Milwaukee M18 dual-speed grease gun. The Milwaukee model seemed to handle tougher fittings and colder temperatures with a bit more ease, and it didn’t experience the same relief valve issues that the DeWalt did under high pressure. However, the compatibility of the DeWalt with my existing battery system was a significant advantage, making it a more convenient choice for me.

Conclusion and Recommendation

In conclusion, the DeWalt DCGG571B Cordless Grease Gun is a highly effective and practical tool for anyone who regularly maintains equipment with multiple grease fittings. Its high-pressure capability, variable speed control, and thoughtful design features like the flexible hose and LED light make it a top contender in the cordless grease gun market.

Would I recommend this tool? Absolutely. If you are dealing with heavy machinery, tractors, or other equipment that requires regular greasing, this tool will save you time and effort. It’s a worthwhile investment that pays off in productivity and ease of use. Just be mindful of the minor issues with the pump filter screen and air locks, and you’ll find this grease gun to be an indispensable addition to your toolkit.
