10 Best Cordless Grease Guns 2025 in Canada

The DEWALT 20V MAX Cordless Grease Gun is a strong choice for anyone needing a reliable and powerful cordless grease gun, especially for tough, clogged grease fittings. Its motor can deliver up to 10,000 PSI, which is excellent for high-pressure tasks. The grease flow rate of 5.0 ounces per minute supports fast, high-volume greasing jobs, saving you time. It offers a 42-inch flexible hose, making it easier to reach grease fittings in tight or awkward spaces. The variable speed trigger adds precise control over the grease flow, which helps prevent over-greasing. The built-in LED light is a nice touch for working in dim or hard-to-see areas.

At 6.7 kg, it’s somewhat on the heavier side, so it might be a bit tiring during long periods of use, but the ergonomic design with a single handle and a no-mar foot helps manage this weight. The inclusion of an air-bleeder valve makes cartridge changes smoother by helping to prime the pump quickly. The grease gun uses a 20V lithium-ion battery, which is common and convenient, though battery life and recharge times depend on usage. It comes with a solid 3-year warranty, adding peace of mind.

For those who want something lighter or for occasional light use, the weight might be a downside. Additionally, while the hose is lengthy, users needing even longer reach may need extensions. This model suits professionals and serious DIYers who want dependable power, good grease flow control, and handy features in a cordless design.

The DEWALT 20V MAX Cordless Grease Gun (DCGG571B) is a powerful and reliable tool designed for those needing a cordless solution to grease hard-to-reach fittings. Its motor delivers a strong 10,000 PSI, allowing it to clear clogged grease fittings effectively. The grease flow rate is a solid 5 oz per minute, which suits both light and high-volume greasing tasks. The 42-inch flexible hose is a great length to access tight or awkward spots, and the bright LED light helps you see clearly in dark work areas, adding convenience.

This tool runs on a 20V battery platform (batteries sold separately), so it offers good power without being tethered to a cord, making it ideal for mobile mechanics or workshop use. Weighing 3.63 kg (around 8 pounds), it’s on the heavier side but includes an ergonomic handle and a no-mar foot design that allows resting the tool safely on surfaces during breaks, which helps reduce fatigue.

The grease gun also features variable speed control for precise application and an air-bleeder valve to easily prime the pump after changing cartridges, enhancing ease of use. The DEWALT grease gun is well suited for professionals or serious DIYers who need a strong, cordless tool capable of high pressure and flow rates with good reach and visibility. While it requires purchasing the battery separately and has some weight to it, its features and performance make it a dependable choice in the cordless grease gun category.

The Milwaukee 2646-20 M18 2-Speed Grease Gun is a strong choice for anyone needing a cordless tool that delivers high pressure with ease. Its standout feature is the impressive 10,000 PSI pressure, which means it can handle tough grease jobs that require more force. The 48-inch flexible hose allows you to reach tight or awkward spots without much hassle, making it versatile for many tasks. Running on an 18-volt lithium-ion battery system (battery not included) gives it good power and cordless convenience, although you’ll need to have or buy a compatible battery separately.

This tool also includes helpful features like an air bleeder valve for quick priming to save time and a lock-on/lock-off trigger that improves comfort during longer use. A unique pre-set grease counter dial helps you keep track of how much grease you’ve applied, which is useful for precision work. Weighing about 4.5 pounds, it’s relatively lightweight and easy to handle, benefiting ergonomics during extended use.

One important consideration is that the product is sold as a bare tool, so you’ll need to invest in the battery and charger if you don’t already own compatible Milwaukee M18 tools. The hose length and cartridge capacity are standard but not exceptional, so if you often need longer reach or larger grease volume per fill, alternatives might be worth exploring. Despite its initial release in 2013, it remains a reliable option with a solid 5-year warranty, reflecting its durability. This grease gun is well-suited for professionals or serious DIYers who want a powerful, cordless device with smart features for efficient and precise grease application.
