The air bleeder valve is a practical feature for quick priming, reducing downtime, while the lock-on/lock-off trigger enhances user convenience by allowing continuous operation without constant pressure on the trigger.

Additionally, the pre-set grease counter dial offers precision in application, which is beneficial for tasks requiring exact amounts of grease. This grease gun is cordless, operating on an 18-volt lithium-ion battery (not included), which eliminates the need for a separate power source and enhances portability. The build quality appears robust with its metal construction, promising durability. However, the fact that batteries are not included could be seen as a drawback, requiring an additional purchase if you do not already own Milwaukee M18 batteries.

The product's weight of 4.21 pounds might be a consideration for prolonged use. Nonetheless, the 5-year tool warranty is a reassuring aspect, reflecting the manufacturer’s confidence in its durability. This tool is ranked #13 in Grease Guns and fits well within the automotive category, making it ideal for professionals and serious DIY enthusiasts who need a reliable and powerful grease gun.

With a 7-foot high-pressure hose, it can easily reach difficult fittings, adding to its versatility.

The heavy-duty control valve and universal swivel provide better handling and control, which simplifies the greasing process, especially in tight spaces. The 4-wheel band-dolly is a notable feature, making it easy to maneuver the unit around the shop, enhancing user convenience. The build quality is robust, with a steel exterior that promises durability and longevity.

Its 39-inch hose provides good reach into tight or hard-to-access spots, and the 2-in-1 rotating handle adds comfort and flexibility by allowing you to switch between pistol and straight grip depending on the job. The build quality is robust with a reinforced steel barrel, and it includes useful accessories like multiple couplers and a shoulder strap to reduce fatigue during extended use.

This grease gun supports both standard grease cartridges and bulk grease, adding convenience depending on your preferred supply method. The built-in LED light is a helpful feature for working in dim conditions. It is important to note that the tool is sold without batteries or charger, so a compatible DeWalt 20V battery is required to operate it. Additionally, weighing over 10 pounds, it may feel a bit heavy for some users, which could affect ease of use.

If you already own DeWalt batteries and are looking for a powerful, versatile cordless grease gun, this model delivers solid performance and useful features. However, the weight and need to purchase batteries separately are factors to consider before making a purchase.
