Milwaukee is another brand that is quite well-known for manufacturing high-quality tools and equipment. And the Milwaukee Bare Tool 2446-20 M12 is no exception! This cordless grease gun is pretty durable and easy to use, making it an excellent choice for both beginners and experts.

The Milwaukee Bare Tool 2446-20 M12 is an excellent grease gun, which is apparent from the highly favorable user feedback. Due to the gun’s ergonomic design, you will find it comfortable to use even after working for long hours.

It also features an LED fuel gauge, as well as integrated hose storage that can store the 36-inch long flex hose. These features make this grease gun pretty convenient for users.

The hose features a spring guard that makes it easy to reach tricky spots. It also comes with an air bleeder valve that primes the gun and ensures a quicker grease flow. 

Overall, we found this grease gun to be pretty good and easy to use. However, there is one aspect that can make using this gun a bit inconvenient. It does not come with a battery and charger in the box, so you have to purchase them separately. Therefore, this can also increase your expenses a bit.

2. Lumax Handyluber 12V Cordless Grease Gun - Best for Personal Projects

The LX-1175 Handyluber is another great cordless grease gun manufactured by Lumax. If you are looking for an affordable yet good-quality grease gun for your personal use, then this one is a pretty good choice.

The Lumax LX-1175 Handyluber is a cordless, 12-volt battery-powered grease gun. While it may not be able to provide as great a performance as some higher-powered grease guns, it is more than sufficient for personal use.

Its battery can easily deliver up to 5 cartridges of grease without needing to recharge. Furthermore, we observed that the 7,000 PSI pressure delivered by the motor provides a good flow rate of 3.5 oz/min. This is more than enough for any personal projects that you may have.

Additionally, the durable and lightweight design makes it pretty convenient for users. And of course, the non-slip grip makes it quite comfortable to handle. You’ll also be happy to know that it comes with a 30-inch ultra-flex hose and a chrome-plated barrel that prevents any corrosion. 

The Lumax LX-1175 Handyluber is a great choice for personal or household projects, given the specifications that it comes with. But this also means it is not very well equipped for extensive or commercial usage. If you try to use it in such scenarios, it will become heated and noisy, reducing the gun’s lifespan.

3. Ryobi 18V Cordless Grease Gun - Best for Commercial Purposes

For the next product on our list, we have the P3410 18V cordless grease gun by Ryobi. This grease gun provides you with another affordable option that you can purchase. And thanks to its powerful motor Ryobi, you can use it for commercial purposes as well.

Our overall impression after using this grease gun was quite positive. We found that the 10,000 PSI operating pressure and 7.5 oz/min grease flow rate are quite efficient, especially considering the 18-volt lithium-ion battery that this cordless gun comes with.

The battery is quite efficient and long-lasting. It can easily dispense a whopping 19 grease cartridges before it needs to be recharged. This grease gun features a steel grease tube that is very durable.

Furthermore, this grease gun comes with an air bleeder valve for quick and easy priming. The 30-inch flexible hose makes greasing difficult spots much easier. In addition to that, you can illuminate those dark and difficult-to-reach spots with the in-built LED light.

The Milwaukee 2446-21XC is a well-rounded grease gun that provides good value for money. However, one major flaw that we noticed while using this gun is that it cannot be used for long durations extensively. If you do so, your grease gun will heat up considerably, which can reduce its lifespan.

Aside from the typical device features and specifications, the different additional features really piqued our interest in this grease gun. The grease gun comes with a 3-point base, which we found provides high degrees of stability. It also complements the gun’s lighter weight and comfortable grip pretty well.

In addition, we found that the dual lip follower is really great at minimizing grease wastage and improving workspace cleanliness by eliminating grease bypass. The 8,000 PSI pressure is also sufficient to eliminate any clogged grease fittings in machines.

This grease gun also features an integrated vent valve, which makes priming and preparing the gun a lot easier by removing any trapped air. It also comes with a 5-year warranty on the gun, and a 2-year warranty on the batteries, so you can use it without any worries.

In addition to the above, the gun features an optional shoulder strap hook for added support and convenience. We found this to be quite a practical addition, especially for carrying the gun around conveniently. 

One major drawback of this grease gun is that it is a bit pricier than some of our previous choices. Furthermore, the grease gun also does not come with a battery and charger, and you will need to shell out extra cash for them.

Motor Power

The power of the motor is one of the most important things that you should consider when buying a cordless grease gun. Grease guns can often come with different motors that can output between 5,000 to 10,000 PSI. 

Low-powered grease guns are often cheaper and used for personal uses. Conversely, high-powered grease guns are used more for industrial or commercial purposes and are more expensive. So, you should choose a grease gun based on your usage preferences.

Hose

Before purchasing a cordless grease gun, you should look up the length and flexibility of the supplied hose. This is important because the length and flexibility of the hose will decide whether you can reach the most inaccessible parts of your machine. If your cordless grease gun comes with a small or stiff hose, you will find very little use for it.

Battery

One of the most important features of a cordless grease gun is its battery. Since a cordless grease gun does not come with wired adapters, you need to ensure that the battery power and battery life of the grease gun are decent. If your grease gun has a poor battery life, you will need to recharge it frequently, which can be a bit annoying.

Also, most battery-powered grease guns use lithium-ion batteries, which are low maintenance, and more environmentally friendly while also being more expensive. Conversely, only a few grease guns use nickel-cadmium batteries, which are heavier but relatively cheaper.

Build Quality

A cordless grease gun is an industrial tool, so it needs to be sturdy and durable to withstand any working condition. Therefore the build quality of your grease gun is important. You should only buy grease guns built with high-grade materials so that you can use them for a long time.

Why should I get a grease gun?

Opting for a grease gun elevates the ease and safety of greasing machinery compared to the manual method, which can often be labor-intensive and disorderly, hence an electric cordless grease gun significantly streamlines this process.

Which is the best grease gun to get?

Selecting the best grease gun can vary based on personal considerations such as usage preference and financial capacity, however reputable brands like Dewalt, Milwaukee, or Lincoln are widely recognized for their superior quality grease guns.

Is there a difference between pneumatic and battery-powered grease guns?

The difference between pneumatic and battery-powered grease guns revolves around their operational methods; pneumatic grease guns require user exertion in creating pressure via a pump mechanism while battery-powered grease guns employ an electric motor, powered by batteries, to effectuate the grease discharge, thus increasing convenience.
