The Lincoln 917 High Pressure Pneumatic Grease Pump is designed for professional use, especially suited for those needing to handle large 120 lb grease drums. It operates at a strong 50:1 pressure ratio, which means it can efficiently deliver thick grease to tough lubrication points. Its pneumatic (air-powered) operation makes it easier to use compared to manual grease guns, reducing effort and speeding up work. The 7-foot hose offers good flexibility to reach grease fittings that are hard to access.

Durability is supported by a sturdy painted exterior, a drum cover, and a roll-around base for mobility, making it practical in busy workshop environments. The included follower plate helps ensure you get the most grease out of the drum without leaks or waste. It is compatible with common grease types (NLGI 1 and 2), which covers most industrial and automotive applications.

The unit is quite heavy (over 46 pounds), which might make it less convenient for quick jobs or smaller setups. Also, as a pneumatic tool, it requires an air compressor, so it's not ideal for users without that equipment. This grease gun is an excellent choice for professional or heavy-duty use, providing reliable, high-pressure grease delivery with good capacity and ease of use in demanding environments.

The 42-inch flexible hose is a nice touch, making it easier to reach tight or hard-to-see grease points, especially with the helpful built-in LED light illuminating dark areas. The variable speed trigger allows you to control grease flow smoothly, which can prevent over-greasing and waste. It also features useful elements like an air-bleeder valve for easy pump priming and a no-mar foot that lets you set the tool down without damaging surfaces. Durability-wise, the tool feels solid and well-made, backed by DEWALT's 3-year warranty.

At nearly 15 pounds, it’s somewhat heavy, which might be tiring for extended use. The plastic body, while durable, may not feel as rugged as some all-metal alternatives.

This grease gun suits professionals or serious DIYers who value power, portability, and precise greasing control, especially when working in hard-to-reach areas.

Milwaukee’s reputation and the positive user rating (4.3 out of 5 stars from over 700 reviews) suggest it performs well in typical automotive or equipment maintenance tasks. The kit comes with two compact batteries, ensuring you have backup power when one runs low. Users have reported that it’s easy to use and handle, which is important for anyone who wants a straightforward tool that doesn’t require much effort or learning.
