If you are tired of using the hand-operated or pneumatic grease guns, then you must try the cordless grease gun as they are easy to use and don’t require much effort.
So if you are looking to buy such a tool, then you are in the right place. We have researched many cordless grease guns according to their pressure output, flow rate, hose length, and much more.
After that, we have selected the best of them and compared them so you can choose the best product. So here are reviews of the best cordless grease guns.
Quick Answer: The Best Cordless Grease Gun
1. DEWALT DCGG571M1 20V Cordless Grease Gun
DEWALT DCGG571M1 is our top pick for the best cordless grease gun. This unit comes with a powerful motor that can easily generate up to 10,000 PSI pressure to let the grease pass through any fittings.
Moreover, you can push as high as 5 ounces of grease per minute using this machine to increase the work speed. Using the included battery, you can use up to 16 cartridges until you run out of power.
Additionally, this battery-powered grease gun features the 42-inch long hose to reach confined areas. Also, the built-in LED lights help you when greasing in low light conditions.
Moving on, the innovative pump filter screen of the machine prevents dirt and contamination from entering the inner mechanism and clogging it.
This battery grease gun includes a 20V 4Ah battery that offers decent runtime, and the variable speed trigger offers precise control of grease flow. And you will get three years of warranty on this product.
2. Ryobi P3410 18V Cordless Grease Gun
Our next product is Ryobi P3410, which also happens to be the cheapest cordless grease gun on our list. It can push the grease at a maximum of 10,000 PSI so you can grease even the toughest clogged fittings.
With a maximum flow rate of 7.5 ounces per minute, you can increase the work efficiency to a great extent. That’s not all; the on-board LED lights help you illuminate the work area.
Also, the 30-inch flexible hose is useful to access hard to reach grease fittings. Additionally, the plunger rod is very convenient and allows the user to know how much grease is left in the tube.
What’s more, the air bleeder valve quickly primes the pump and reduces the air pockets. This unit features the lock-on/off trigger to eliminate the mess from the machine’s accidental startup.
When using 4 Ah battery, it can pump about 19 grease cartridges per charge and note that it is not included in this package. And let’s not forget the included three-year warranty.
3. Milwaukee 2646-20 M18 Battery Grease Gun
Milwaukee is also a great brand that produces reliable products with the solid build quality. The Milwaukee 2646-20 M18 generates the industry-leading 10,000 PSI of working pressure for the user’s convenience.
At 10 ounce per minute, it produces the highest amount of flow rate compared to other battery grease guns in our list.
This battery-powered grease gun comes with the massive 48-inch long flexible hose to reach difficult fittings. For the priming, this unit comes with an air bleeder valve for quick flow.
The Milwaukee cordless tools use the M18 REDLITHIUM system, which is compatible with all their tools, so it gives you greater versatility. Other than that, the lock-on/lock-off switch will prevent a mess if you accidentally press the trigger button.
Sadly, this unit supports up to 10 grease cartridges per charge; however, you can increase the runtime by using the higher amp-hour battery.
4. Lincoln 1884 20V Li-Ion Battery-Powered Grease Gun
Lincoln is a widely known brand for producing the best grease guns, and they even make manual grease guns, air grease guns, and cordless grease guns as well. The Lincoln 1884 PowerLuber includes a dual battery and a charger with the whole package to get you started right off the bat.
When the tool is resting on the surface, its three-point base keeps it upright and stable so you can work efficiently. Also, the grease gun itself is very lightweight and compact, so you can easily access those tight fittings.
The convenient LED light comes in handy when you are working in a dark environment. What I like most about this battery grease gun is its LCD display that shows information like grease output, remaining power, and alerts the operator when fittings are blocked or loss of priming occurs.
Thanks to its two-speed digital output selector, you can choose between low-volume and high-volume dispensing. It delivers 10,000 PSI of operating pressure in both high and low-output settings.
5. Ingersoll Rand LUB5130 Lithium-Ion Cordless Grease Gun
Ingersoll Rand LUB5130 is rated for 6250 PSI pressure output and 2.6 ounces per minute of flow rate. And with this amount of power, you can do more work in less time.
The unit we are reviewing here is a bare tool; however, there is another variant as well that comes with a battery and a charger. Due to its lightweight design (7.2 pounds), you will experience less fatigue even after working for long hours. The ergonomic handle with an over-molded grip will reduce vibrations even further.
What’s more, the optional shoulder strap hook adds more flexibility and support. Ingersoll Rand LUB5130 boasts steel-reinforced metal gears, heavy-duty motor, and robust housing that all increase the machine’s overall life expectancy.
The product is equipped with a standard 30-inch hose that helps the operator reach the tight spots, and you will get three years of swooping warranty on this cordless grease gun.
