This tool offers remarkable qualities that are sure to impress beginners and veterans alike, though its professional design and price tag make it a favorite among experts most of all. Regardless, the Dewalt electric grease gun is a prime example of a high-quality cordless gun and would be an ideal tool for anybody with convenience in mind.

Key Features We Like:

  • Powerful motor is able to deliver a maximum of around 10,000 psi

These previously reported issues should be kept in mind if you consider this product, though we are sure for many people this product's powerful motor and flow rate will more than balance these issues out. While maybe not the most reliable product on this list, we still consider this gun to be an ideal choice for those looking to begin their greasing experience.

Buyer's Guide- Things to Consider

Here we will look at some of the features that you need to take into account if you want to find the best product for your needs. Go through these features and then decide on the product that not only fulfills your budget but also your job requirements.

Types of Machinery/ Volume of Grease:

A key factor that any buyer should consider before deciding which product is the right fit for them is the application of the tool. What machinery is it being used for? The type of machinery that the gun is being used on will determine a number of other factors, including the volume of grease that will be needed for any given job. Different types of guns are recommended for different jobs, with low-volume jobs it is recommended that manual application grease guns, such as pistol grip guns are used.

Whereas, for high-volume jobs such as the previously mentioned wind-turbine upkeep and farming, it far more ideal for both battery-operated and pneumatic style guns to be used, such as the many options we have listed previously. Though, many also attest to the fact that when using a pneumatic style grease gun, the process can become inconvenient, as the user is required to drag an air hose around with them wherever they go. When deciding between purchasing a manual and battery-operated gun, the first question should be of the scale of your job and the amount of grease needed. This should make deciding between the two far easier.

Operator Energy/ Fatigue:

Another factor that plays an important role in deciding which grease fun type will best fit your needs is to consider your own energy levels as the user and operator of the device. As the name implies, manual devices are pumped by hand, whether lever or pistol grip, and as such you should ensure before purchasing such a product that you are physically capable of this level of physical labour. There are many reasons that this may not be a realistic option for many, whether due to age, injury, disabilities, or other factors, there is no shame in this fact at all and we simply recommend that these users look into either a battery-operated or pneumatic product over its manual alternatives.

That being said, it should be noted that levels of operator fatigue are reported far more commonly with lever grip products as these must be reloaded and often operated with both hands, and often a great deal of struggle. If you are still set on purchasing a manual gun but are worried about operator fatigue and your own energy levels, then we recommend the use of a pistol grip gun instead, such as the Slippery Pete Pistol Grip Grease Gun from our list.

Noise Output/ Hearing Protection:

A final thing that should be considered by any customer before they purchase is the noise levels involved with the greasing process and how this differs depending on the type of gun that is being used. Pneumatic guns, in particular, are often noted to have a very high noise output, being so loud that operators are often advised to wear ear protection to prevent damage. With this in mind, you should consider the jobs that you intend to use this tool for and whether this noise may cause any issues. For example, those primarily using their guns for day-to-day household jobs are not likely to want such a high level of noise, especially if they live in a residential area where they may receive complaints.

In order to reduce this risk, as well as to ensure that your own and other's hearing is not affected by this noise, we advise against this specific kind of gun being used in such an environment when it can be avoided. In this case, we advise instead that a pistol-grip or battery-operated device may be a better fit for the user's needs and surroundings. In the end, it's the choice of the individual whether they decide to endure the very high decibel levels of a pneumatic gun, but we feel it is something that customers should at least know about before they purchase one.

Frequently Asked Questions

What are the Main Differences between the Four Grease Gun Types?

When it comes to grease guns, there are centrally four different types that most people will come to know, lever grip manual types, pistol grip manual types, pneumatic types, and battery-operated types. Each different type is ideal for different tasks and has a range of advantages and disadvantages; we will briefly run through them each and the key differences between these four types:

  • Lever Grip (Manual) - This was the first and is often still the most common type of grease gun on the market. It is hand-operated and ideal for smaller, low-volume jobs. These guns provide grease to the specific area, this grease is forced through and out of the gun's aperture by hand pumps. While simple, this method often leads to a great deal of fatigue due to its physical nature.
  • Pistol Grip (Manual) - This type of gun is a variation of the original lever-type grease gun. However, pistol grip guns allow for a one-handed pumping process, which is preferable to many people. While it dispenses grease at a slower rate than its lever grip competitors, its one-handed design and less energy-consuming operation makes these types still popular today even against electric models.
  • Pneumatic - This type of gun utilises compressed air that is directed into the gun by a hose, this hose is operated by a trigger that the operator can pull. A favourite of many, pneumatic guns are ideal for larger jobs that require a high volume of grease. As opposed to manual guns, operator fatigue with this type is practically unheard of.
  • Battery-operated - This is a low-voltage battery-powered gun type that works in a similar way to the previous type, pneumatic grease guns. However, on top of this battery-operated guns offers the additional benefit of being cordless, adding convenience and portability to the tool.

Which Couplers/ Adapters/ Connectors are Best for Me?

A coupler/adapter/connector can be your best friend in a pinch! Grease guns often come with a standard connection adapter, such as a hydraulic coupler, but there are many other variations of these connectors, adapters and couplers that can be alternated depending on the task at hand. The standard hydraulic coupler is the most common and by far the most versatile example of one of these connection adapters, being appropriate for a find range of jobs and environments.

On the other hand, a 90-degree adapter is excellent for jobs that are in confined areas and that therefore require a 90-degree bend in the process. A needle-end adapter provides a thin and very precise amount of grease and is ideal for jobs where precision is key. Ultimately, we can't decide which of the wide range of connection adapters that are out there will suit you and your gun the best. Still, just as with the gun itself, we advise that you find the best grease gun coupler for you. One that meets your specific needs when a particularly tricky job comes around.
