Things to Put into Consideration Before Buying the Best Cordless Grease Gun
Cordless grease guns are not born equal. Some deliver superior performances than others. Finding the best is therefore not an easy task given the numerous options available. However, when you are armed with this buying guide, be sure to end up with the best of the best.
1. Amount of Pressure The Gun Generates

Delivery of the required amount of pressure is what makes a grease gun good at its job. Depending on the nature of the particular task you will be doing, you might want certain amounts of pressure to be delivered by the gun.
You need to choose the amount of pressure carefully as it determines how well the parts will be lubricated. All in all, you need the highest pressure that your budget can allow. For high-pressure professional needs, 10,000 PSI should generally ensure proper greasing for you.
However, some people might not need such powerful performances. You could need a gun to grease your bikes, washing machines or even treadmills. With these tasks, a 5,000 PSI greasing gun would provide you with optimal performances.
2. Grease Gun Types
Cordless grease guns are available in three types. These include hand operated, air operated and battery powered. All these have their own sets of advantages and suit various applications. The types that you choose should meet your style, application and budget.
a) Hand operated
These types are also called pump, traditional or manual grease guns. To operate them, you have to squeeze a handle so that enough air pressure is generated to push out the lubricant through the nozzle. The Piston grip guns always fall into this category.
If you want versatile tools and you have the willpower of squeezing the grease out, then this could be your choice.
b) Air/pneumatic grease guns
Instead of squeezing the grease out manually, these types use air pressure from a compressor to force the lubricant out through the nozzle. To use these, you would have to own a compressor too and contend with the loud noise produced.
c) Battery powered
If cords are a hindrance to your job, then ditch them for the battery-powered grease guns. And when the power from the battery runs out, you simply plug it into recharge and continue with your job.
Their portability is one of the most enduring features of these types of grease guns. You would be able to use it anywhere you want.
3. Battery life
For the battery-powered grease guns, battery life is an essential consideration that you will have to make. The best cordless grease gun should have a considerably longer battery life. When you are working in a remote place without a power outlet, you should not be inconvenienced.
A longer battery life is also useful when you need to work without interruptions. Having to stop working to recharge is not what a DIY enthusiast always wants. If the battery can last you through several projects, the better for you.
The battery should also have the capacity to deliver a consistent performance even when running low. You would not want the performance to reduce when running low on power. Better still, there should be an indicator that shows how much power is still stored.
4. Grease gun fittings
If you want to bring the best out of your greasing work, you need to ensure that the gun has the proper fitting. These fittings also allow you to get access to other equipment. In some quarters, these are referred to as nipples, alemite fittings or Zerk fittings. They are available in a number of options namely:
5. Grease gun adapters, Connectors and couplers
Most of the grease guns that you can find around have a standard adaptor. The most common is the hydraulic coupler. However, there are several others that you can choose from.
6. Grease meter
How do you know that you have applied the right amount of grease to a bearing? In most cases, you don’t, and this creates a problem. Applying less grease shortens the joint and bearing life while too much leads to wastages.
The best cordless grease guns come with a meter for monitoring how much grease has been squeezed out for a more economical application. It could be digital or analog, but it helps you apply the right amount of grease recommended by manufacturers.
7. Grease loading mechanism
Every grease gun has its own way of being loaded with grease. Refreshing the grease supply is not an easy task. Therefore you need a gun with an easier method. The most common methods include suction, bulk re-fill or suction fill.
The choice that you make depends on your gun preferences and how you are comfortable using any of them.
8. Accessories
Apart from these features, the best cordless grease guns also have other features to make using them a lot easier. It could be a comfortable handle, an LED light for use in dim areas or color corded gun caps to avoid contamination of various grease lubricants.
There are certain types of guns that you can vary the speed at which the grease is dispensed. This is useful when you are performing different jobs needing different amounts of grease.

Overview
The CarBole Grease Gun is ideal too for agricultural, automotive, trailers, marine and industrial uses. If your job involves any of these areas, then you could find this grease gun quite useful.
This grease gun produces a maximum pressure of about 10,000 PSI, of which 6,000 PSI is usable as the working pressure. This pressure produced should be sufficient enough to perform most of your greasing and lubrication jobs.
The barrel of this tool is made of anodized aluminum so that it is rust free. The presence of rust in the barrel greatly reduces the efficiency of the tool. You, therefore, have to use greater efforts to squeeze out the lubricant.
To withstand the immense pressure generated by the lubricant, an aluminum head that is die-casted is fitted with the gun to withstand the pressure. This aluminum head and barrel greatly reduce the overall weight of the grease gun. Less weight means less strain on you as the user.
For ease and flexibility of use, a 12-inch heavy duty flexible hose that has been triple reinforced is included in the package. With such a strong built, the hose cannot burst even when under pressure. Besides the hose, there is also a 5 3/8-inch grease pipe plus a coupler.
And since you will be using your hand to operate this grease gun, it is fitted with a heavy-duty aluminum pistol grip. Consequently, this makes one-handed operation a lot easier, just as the pistol handles the constant squeezing.

Overview
The Lincoln Grease Gun is a pneumatic grease gun meant to tackle your industrial lubrication needs. This grease gun is fitted with an automatic variable speed trigger that varies the lubrication speeds. With such a feature, you can apply grease to most lubrication points.
An advanced pumping system provides a priming free grease gun operation. This feature, when combined with the variable trigger, gives an excellent control of the grease flow.
A pumping ratio of 150 pounds per square inch (PSI) provides an efficient use of the air pressure applied. This, in turn, generates a maximum pressure of 6,000 PSI. This kind of grease pressure is enough to lubricate a lot of your DIY needs.
To produce this amount of pressure, an air pressure ranging from between 40 and 150 PSI is needed to run it. As it squeezes out the grease, a 30 inches long grease hose transfers to the lubrication point.
This high-pressure hose can comfortably handle the immense amount of pressure generated. The hose works with an attachment clip and a coupler for better operation ability. In addition, a check valve assembly is incorporated in the design to facilitate a superior grease flow.

The Dewalt 20-volt grease gun is a battery-powered grease gun, being powered by a 20 Volt MAX Lithium-ion battery. This powerful battery then drives the gun’s powerful motor to deliver about 10,000 PSI of power.
With this amount of power, clogged fittings are no longer a challenge to grease. These clogged fittings provide a particular nightmare for DIY enthusiasts like you. I hate greasing those and I guess you do too.
To accommodate the power delivered by the motor, a high-volume pump capable of squeezing about 5.0 ounces of grease per minute is fitted on to the gun.
Additionally, a single charge of the 4.0 Ah DEWALT battery is enough to power you through 16 cartridge changes. With this amount of runtime, you should be able to perform all your tasks uninterrupted for a long while.
All these features make this grease gun suitable for high flow grease applications. As a professional, these are the kind of features that you would find useful in the course of your work.
Another feature you will find useful is the variable speed trigger. You might find a job that requires less power to grease, while the next one would need a greater amount of grease. With a variable trigger, all these tasks will be completed with ease without changing grease guns.
Less grease is therefore wasted in the process with such precise controls. This grease is then channeled through a 42” long flexible high-pressure hose. This hose enables you to reach those hard to reach fittings that are to be greased.
To further assist you in completing your greasing jobs in hard to reach and poorly lit places, this tool comes with an LED light. Locating grease fittings in low light conditions should not be a problem anymore.
This grease gun also features a filter screen within its pumping system. This allows for the filtration of dirt that would otherwise contaminate and clog the pumping mechanism. An interruption-free operation is therefore guaranteed.
There is another unique feature included in the designing of this grease gun. That is the no-mar foot design. With this feature, it is possible to have the tool rest on any flat surface. An air bleeder is incorporated to aid in the priming of the pump after a cartridge change.

The Lincoln Grease Kit is a combination of a cordless grease gun, 2 batteries and a fast charger for a high-pressure greasing job. In return, this tool delivers a performance 5 times that of other manual guns.
The grease gun included in the kit is capable of generating up to about 6,000 PSI pressure for performing your greasing jobs. This pressure, in turn, enables a continuous operating flow rate of 2.6 Ounces per minute.
With the trickiness that comes with the loading of a new tube of grease, operating this grease gun is made easier with the enabling of a 3-way loading system of the gun. No more fumbling with the loading of a new set of grease.
The 12 volts NiCad rechargeable battery is powerful enough to run the gun through 3 grease tubes on a single charge. With such a prolonged battery runtime, recharging is minimized, meaning that you will finish your projects within the scheduled time, and then move to the next.
A flexible grease gun of 30 inches is provided to enable you to reach those hard to reach spots. In this way, you will leave no fitting ungreased. A three-way loading mechanism is provided too to make your refills a lot easier.
For the safety of the motor, a pressure relief valve is fitted in the grease gun design to prevent any possible damage to the motor. This normally occurs when there is excess pressure buildup in the gun.

The Lumax Grease Gun is a pistol grip grease gun meant for the heavy-duty stuff. This particular tool comes with an 18 inches long flexible grease hose. Such a length is appropriate for the difficult to reach grease fittings. Better still, this grip features a chrome material plated to provide the maximum level of protection from corrosion. And because it is contoured, a strong grip is generated.
The tool’s barrel is made from a heavy-duty gauge steel. This barrel can survive lots of the drops that will be taking place as you use it. Additionally, a follower spring (heavy duty) is incorporated into the design to provide a consistent priming each time.
For easy refilling, there is a Posi-lock follower rod that has been ergonomically designed to include a T-handle for a sure grip. With this type of handle, you can refill the barrel at any position. After filling, a heavy-duty follower provides maximum sealing for eliminating any grease bypass.
Every 100 strokes of the grease gun, 115 grams (4 ounces) of grease is dispensed from the nozzle. All these are channeled through the 18 inches of an extension pipe. There are also 4 hardened hydraulic coupler jaws and a non-drip cap.
While using this grease gun, don’t hold the hose. By being able to be loaded in three different ways (suction, grease pump and cartridge), your work is made easier. Up to 7,000 PSI of pressure develops at the heavy-duty cast gun head. Additionally, an air bleeder vents out air pockets in the grease.
