The best part of working with machines is the efficiency and the convenience they give you. Tools make work easier and should reduce your efforts when doing work. When the efficiency of the machines is compromised, the efforts applied to doing the job are increased, adversely influencing the outcomes.
Often, the efficiency of the machines is affected when energy is lost through friction between the moving and stationary parts of the machines. You do not need to destroy or dump your tool in such an instance. Instead, you should apply a lubricant to reduce the frictional forces.
The lubrication of the machine parts makes them slippery and plays an essential role in bearing, machine function, and longevity by reducing wear and tear. The friction can be reduced by greasing the parts.
However, the market is characterized by numerous grease guns, and getting the best to suit your purpose can be challenging. We have done the leg work for you, tested, described, and listed the best cordless grease gun models suitable for different greasing applications. We have also provided a comprehensive and informative buyer’s guide to help you make the best purchase decision.

What is a Grease Gun
A grease gun is a standard workshop and garage tool used to lubricate machine parts. The grease gun applies the lubricant to particular points through an aperture to a grease fitting. The channels behind the grease fittings direct the grease to where the lubrication is required.
The lubrication helps reduce friction between the moving and steady parts of the machine, and this helps improve the engine’s efficiency. The lubrication also helps improve the lives of the tools, reducing wear and tear due to frictional forces in the process.
Why you need a grease gun
- Minimized wastage. A grease gun gives you control of the amount of oil from the gun to the grease fittings. You also control when you should release the trigger and when you shouldn’t. In the process, you can control the grease usage, preventing wastage. You only release the trigger when and where the oil is needed and ensure that you release the required amounts.
- It improves the longevity of your machine. The gun helps enhance the life of your machine. This ensures you do not consistently invest in another gun, saving you money and time.
- Improved saturation. The gun constricts the oil or grease precisely where needed and gives you the best greasing output. The constriction or saturation ensures you aim to the point that requires greasing, also minimizing wastage.
- Enhanced speed and accuracy. With the grease gun, you are assured of accuracy and application at the right speed. The grease guns come with different flexible inches of the hose. The hose sizes ensure that you target the right grease fittings, improving the accuracy. You can pull the trigger to ensure speed by varying the pressure, depending on how fast you intend to do the greasing.
Generally, a grease gun is an essential tool you should consider having within your garage or workshop and within your homes to work within your lawns. The tool ensures enhanced productivity and accuracy and minimizes wastage. It helps save costs, hence an economic tool.
Why you should choose Cordless grease guns
Corded grease guns are hard to use, especially in hard-to-reach areas. The cordless type will help you reach various areas where the corded one may not reach, thus facilitating greasing. The cordless guns are portable and thus facilitate easy movement.
Also, since they are battery-powered, you can effectively recharge the batteries or change them if the batteries are compatible with those of the other models in your tool collection. Thus, the cordless tools give you the convenience and efficiency to execute various grease fitting projects.

Best Cordless Grease Gun Buyers’ Guide 2024
What to Consider when Choosing the Best Cordless Grease Gun
PSI Level
The pressure produced by different models varies from one tool to the other. The higher the PSI value, the faster the machine dispenses grease and, thus, an essential consideration when making a purchase decision.
Most products we have reviewed have PSI ranges between 4500 to 12000PSI. When you are working on a construction site or a professional, you can go for a model with a higher PSI value from 6000PSI since such a model will provide you with a high-pressure output for extended use.
On the other hand, if you are working on fragile machinery or products, you should choose a model with a low PSI level below 6000. In such a case, you should also consider a lightweight or more basic model for light work.
Size
The size of the grease gun you buy is also an essential determinant in making purchase decisions. If you’re a professional or have multiple workshops or garages, movements between these places will be involved.
We recommend the smaller model rather than a standard-size tool if you need to travel with your tool.
The only disadvantage with such a tool is that it can have fewer features and reduced pressure levels and may not be applied for extended usage. In such a case, it would be great for use on a small scale, within homes, and in your lawns.
Warranty
One of the most compelling features you need to consider before investing in any brand is the warranty period. Undoubtedly, some products, whether new or used, sometimes come with manufacturing products that we may not identify at the time of purchase.
We recommend that you go for a model with at least a one-year warranty to cover the defects that you may experience during the period to be covered by the manufacturers. It also prevents organizations from selling counterfeit goods.
The duration of a warranty an organization gives always translates to the amount of trust an organization has in its products. The higher the warranty, the more durable and efficient the tool is worth your investment.
Handle grip
Comfort is an essential feature when you are deciding on the best cordless grease gun to buy. The comfort allows for extended use with the machine and improves the convenience and efficiency of your work output.
A handle grip is essential when buying the best cordless grease gun, ensuring the machine’s comfort.
Various models come with a comfortable, rubberized pistol grip, while some are suitable to operate single-handedly. The pistol grip handle and the knurled barrels improve the grip and the holding comfort when you use the machine.
You should also consider having a feel of the model you want to buy and evaluate if you will be comfortable working with the tool. Look for a well-built handle on a grease gun.
Conclusion
Choosing the best cordless grease gun can be daunting, especially when buying for the first time. The robust information in the internet sources even makes it more confusing, and your determination to get the best model for your project can be thwarted by such monotonous information online.
However, I have researched and listed the twelve best models and provided essential features to help you make the best purchase decision. Feel free to read through and get the best model to serve you right.
