1. DEWALT 20V MAX Grease Gun Kit

  • Brand: DEWALT
  • Manufacturer: DEWALT

The DEWALT 20V MAX Grease Gun Kit is the premium option in this lineup, offering a robust motor capable of delivering up to 10,000 PSI and a high-volume pump pushing 5.0 oz/min. Its 42-inch flexible hose and integrated LED light make it ideal for hard-to-reach areas, while the variable speed trigger allows precise control. This kit includes a 4.0 Ah lithium-ion battery and charger, ensuring extended runtime and convenience for users tackling demanding tasks. The build quality is excellent, with thoughtful features like a pump filter screen to prevent contamination and an air-bleeder valve for easy priming.

Performance-wise, the DCGG571M1 excels in heavy-duty applications, such as maintaining industrial machinery or large agricultural equipment. The high-pressure output ensures efficient lubrication even for clogged grease fittings, while the ergonomic design minimizes user fatigue during extended use. However, at 14.8 pounds, its weight may be a concern for users seeking portability. Overall, this model is a top choice for professionals who prioritize reliability and comprehensive features.

DEWALT 20V MAX Grease Gun

2. DEWALT 20V MAX Grease Gun

  • Brand: DEWALT
  • Manufacturer: DEWALT

The DEWALT DCGG571B is a slightly stripped-down version of the DCGG571M1, offering similar core features without the included battery and charger. Like its premium counterpart, it delivers 10,000 PSI and a 5.0 oz/min flow rate, making it suitable for high-flow applications. It retains the 42-inch flexible hose and LED light for accessibility in tight or dark spaces. The bare tool option is ideal for users who already own DEWALT 20V MAX batteries, allowing them to save on upfront costs.

In terms of performance, the DCGG571B matches the DCGG571M1 in output and efficiency, but its lighter weight (8 pounds) makes it more portable. This model is best suited for users who need a reliable grease gun but don’t require a complete kit. However, the lack of included batteries and charger means additional purchases may be necessary for first-time DEWALT users.

Pros

  • 10,000 PSI motor for high-pressure applications
  • 42-inch flexible hose for accessibility
  • LED light for improved visibility
  • Lightweight design enhances portability
  • Cost-effective for existing DEWALT users

Cons

  • Brand: Milwaukee
  • Manufacturer: Milwaukee

The Milwaukee 2646-20 M18 Grease Gun stands out as the budget option in this comparison, offering a competitive price without sacrificing essential features. Its 10,000 PSI operating pressure and 48-inch flexible hose provide excellent reach and performance for most maintenance tasks. Unique features include a pre-set grease counter dial for precision and lock-on/lock-off trigger functionality for convenience. However, like the DEWALT DCGG571B, this model is sold as a bare tool, requiring separate purchases of batteries and a charger.

This grease gun is particularly suitable for users seeking affordability without compromising on performance. Its ergonomic design and intuitive controls make it user-friendly, while the longer hose enhances accessibility. However, the absence of included batteries and charger may deter first-time buyers. Additionally, it lacks advanced features like an integrated LED light, which could impact usability in dimly lit environments.

Pros

  • Affordable price point
  • 10,000 PSI operating pressure
  • 48-inch hose for extended reach
  • Pre-set grease counter dial for precision
  • Lock-on/lock-off trigger for convenience

The STEINBRÜCKE GGP-008 offers impressive specifications, including a maximum pressure of 12,000 PSI and a 40-inch flexible hose for accessibility.

This model is best for users who need high pressure and flexibility but are willing to take a chance on a less-established brand.

Pros

  • 12,000 PSI for superior pressure output
  • Dual operation modes for versatility
  • High-quality 4000mAh lithium battery
