10 Best Cordless Grease Gun 2026 in the United States

The Milwaukee M18 Cordless 2-Speed Grease Gun Kit is a solid choice if you want a reliable cordless grease gun for automotive or industrial use. It weighs about 13.9 pounds, which is typical for a powerful tool in this category. The kit runs on Milwaukee's M18 battery platform, known for good battery life and consistent power. The 2-speed feature allows better control over grease flow, making it easier to handle different job sizes efficiently.

Customers rate it highly (4.5 out of 5 stars), praising its durability and ease of use. It doesn't come with batteries included, so you'll need to have compatible Milwaukee M18 batteries or purchase them separately. This grease gun is well-suited for professionals or serious DIYers who value power and convenience, but if you need a lighter or more budget-friendly option, there might be simpler models available.

The DEWALT 20V MAX Grease Gun is a solid choice for anyone looking for a reliable cordless tool to handle lubrication tasks, especially in automotive or machinery settings. With a maximum pressure of 10,000 PSI, it can effectively power through clogged grease fittings, making it a strong performer for demanding tasks. Its high-flow pump pushes out up to 5.0 oz/min, catering well to high-volume applications, which is a significant advantage for users needing to dispense grease quickly.

The variable speed trigger allows for better control over the grease flow, which can help prevent wastage and enhance precision. Additionally, the 42-inch flexible hose is a standout feature, enabling users to reach tight spots and difficult angles, which is often a challenge with traditional grease guns. The built-in LED light is a thoughtful addition, helping to illuminate dark work areas, ensuring that you can locate even the most hard-to-see grease fittings.

However, there are some aspects to consider. The tool is sold as a bare unit, meaning it does not come with batteries included, which could be an issue if you do not already own compatible DEWALT batteries. Weighing in at 8 pounds, it may be slightly heavy for prolonged use, particularly in overhead applications.

The Seesii Grease Gun (model B003) is a versatile and powerful tool designed for those who need efficient and easy greasing solutions. Equipped with a high-pressure capability of up to 12,000 PSI and a flow rate of 5.3 oz/min, this grease gun is ideal for heavy machinery, trucks, tractors, and construction equipment. It comes with two 2.0 Ah rechargeable batteries, ensuring extended use and compatibility with Ma-kita 18V batteries, which is a plus for users with existing tools from that brand.

The 39.4-inch flexible hose and built-in LED light make it practical for use in hard-to-reach and low-light conditions, enhancing precision and ease of use. The inclusion of a shoulder strap helps to reduce physical strain during extended use, which can be particularly beneficial in cold weather conditions where flexibility might be impacted. Additionally, the tool offers different loading options, supporting both bulk and 14 oz cartridge loading, which provides users with flexible and cost-effective greasing options.

However, at 11.66 pounds, it is relatively heavy compared to some other cordless grease guns on the market, which might be a drawback for users looking for a lighter tool. The comprehensive kit includes various accessories and a carrying case, which adds value by ensuring everything is organized and easy to transport. Seesii also provides 24 months of technical support and lifetime service, offering peace of mind. This product is best suited for users such as farmers, construction operators, and truck drivers who require a robust and reliable greasing tool for maintaining their equipment.
