DEWALT DCGG571M1 (Electric Cordless)

Dewalt is one of “THE BRANDS” when it comes to producing heavy application tools. we had to include a product from Dewalt. Rest assured that DEWALT 20V MAX Cordless Grease Gun is the best Cordless grease gun in the market.

What does it offer? In one word-“everything”. It’s powerful, durable, and efficient. Attached with a powerful motor (that can deliver up to 10,000 PSI), you can do your job efficiently. The motor is backed up by a  lithium-ion battery which is capable of pushing 16 cartridges per single charge.  As the pump can push up to 5 oz. per minute, this product from Dewalt is perfect for heavy applications. With its 42-inch flexible hose, it’s easy to reach the most difficult area.

Overall, we’ll use 3 words to describe this little tool- “Efficient”, “Durable”, and “Convenient”. In fact, most people(who bought it) would agree

MILWAUKEE’S ‎2646-20 (Electric Cordless)

This is the second product on our list and it is as good as the first one. In fact, some of its features are even better than the first one. First of all, it has a larger hose(48″). Secondly, it’s lighter and easier to move around. With 10,000 PSI of operating pressure, it sets the groundwork for heavy application. Furthermore, other cool features include an onboard LED light, a lock-on/lock-off trigger, and a 2-speed function. Overall, it’s a great grease gun to have and it is worth your money.

Lincoln LIN1844 (Electric Cordless)

Firstly, let’s get one thing clear. This product from Lincoln is not the cheapest out there. We have done our level best to make sure that most of our tools are affordable yet good. But we still decided to include it because of its superior performance. Its 18-volt powerful and heavy-duty battery can deliver up to 10 grease cartridges. Furthermore, with 7500 PSI, it does a pretty decent job. Plus its 2-speed transmission feature makes it even more dynamic. To make your life easier, it also offers other minor yet effective features. For example, you’ll get a carrying case and it’s really easy to grip this tool. But the best aspect of this tool is that it’s the most durable tool on our list. This is where it stands out.

  • Lasts longer.
  • Easy to use.
  • Dynamic and versatile


  • very expensive

Astro APT-101 (Mini)

So far all of our products have been slightly on the expensive side because all of them are electric grease guns and all of them are designed for professionals. It’s time to change that. Let’s talk about something that is affordable but offers great features at the same time. We will talk about manual grease guns that are made for common DIY enthusiasts and professionals from now on.

Astro Pneumatic Tool 101 Mini Grease Gun is exactly that kind of product. It will not give you the performance of a lifetime but if you are tight on budget, then this is the right tool for you. It’s compact, lightweight, and convenient. It can hold up to 3 ounces of lubricant and you can operate it with only one hand. That’s how easy it is to use. Even though it’s not designed for heavy-duty applications, you can use it roughly when needed.

Astro APT-101 Mini Grease Gun


  • Very affordable.
  • Easy to use.
  • Lightweight, simple and versatile.


  • Not ideal for heavy application

Lumax LX-1152 (Pistol Grip)

Let’s talk about a tool from Lumax. The design is nothing extraordinary. It’s rather simple which isn’t bad because a simple design is relatively convenient for many users. First of all, let’s talk about the PSI. With  7,000 PSI, it does a pretty good job. Corrosion won’t be an issue with this tool because of its chrome-plated finish. It’s easy to handle the tool because of its design. Its 18″ flex hose may not be the longest hose in the market but it will do a decent job. But the best aspect of this tool is that it’s affordable.

Lumax LX-1152 Pistol Grip Grease Gun


  • Affordable.
  • Easy and convenient.
  • No corrosion.


  • The flex hose is a bit short.

Lincoln LIN1134 (Pistol Grip)

We have another product from Lincoln but this one is not as expensive as the last one. In fact, this is one of the most affordable grease guns you will find in the market. Developing up to 7,500 psi, the Lincoln 1134 Extra Heavy Duty Pistol Grip Grease Gun does its job perfectly. As it features an 18-inch whip hose and a 6-inch rigid extension, you can do all sorts of lubrication jobs with it. That’s the beauty of this tool. Not only it’s durable, but it’s also quite comfortable. Its special pivot angle makes it easy to use. Overall, Lincoln 1134 Extra Heavy Duty Pistol Grip Grease Gun is quite handy if you are looking for a good yet affordable grease gun. That’s why we had to put it on our list and rest assured that you won’t be disappointed with it.

  • Easy and comfortable.
  • Durability is excellent.
  • Affordable.


  • The flex hose is a bit short.

Bravex SW-02 (Pistol Grip)

This little tool is so popular that we had to include this one. What is so good about it? What’s the reason for all the positive feedback it has. First of all, the canister is made of a cold-drawn steel tube. Basically, it means that you won’t have to worry about the durability of this tool. Plus, it’s designed in such a way that there is no chance of grease leakage. Gripping it is easy because of its “non-slip rubber grip”. Using it is pretty convenient. The 18-inch flex hose is not as long as some of the other flex hoses but it does a job. Most of these features look pretty good. However, there is an issue with the PSI. Working pressure can go up to 6000 PSI which is not bad. But we have seen better. But overall, the product is pretty decent for its price.

Bravex SW-02 Pistol Grip Grease Gun


  • Durable.
  • Affordable.
  • The non-slip rubber group makes it easy to handle.


  • The PSI could have been a bit better. 

REXBETI LN0909 (Pistol Grip)

This is another popular yet affordable product in the market. For some reason, it looks quite good. the design is nothing extraordinary but somehow the color and the design go well together. Its 18-inch long flex won’t do a brilliant job but it’ll get the job done. It has a strong handle which gives you the leverage you need. So using it is not really uncomfortable. With 6000 PSI working pressure, you won’t get that cutting-edge performance. But it does all right if you think about the price. To prevent rust, they have added lubricating oil to the gun.

REXBETI LN0909 Pistol Grip Grease Gun


  • Not too pricey.
  • Easy to use.
  • Lasts longer.


  • Better PSI could have made it perfect

LockNLub LNL252 (Pistol Grip)

We are almost done with our list. Now, this is an interesting tool. You may ask why it’s interesting? Well, when we looked at it for the first time, we had a very poor impression because it just did not look good. However, all of that changed after we used it. The PSI can go up to 8000. It feels more than that when you use it in real-time. Its ergonomic grip and lightweight design will make sure that you feel comfortable while using it. Furthermore, the loop-and-lock design makes sure that the coupler is secure and clean when you are not using it. A 20-inch hose will help you out to reach the “hard-to-reach” areas. It’s not cheap but it’s not expensive either. You’ll find the price quite reasonable.

LockNLub LNL252 Pistol Grip Grease Gun


  •  Lightweight and ergonomic.
  • Powerful and versatile.
  • Durable


  • Some customers did not find it convenient

Lincoln LIN1162 (Pneumatic)

This is the last product on our list and it’s the 3rd product from Lincoln. For us, this is the best one from Lincoln because it offers almost everything at a very affordable price.

Let’s talk about the features it offers. First of all, the PSI is max 6000. Secondly, the hose is 30 inches long which is really great. Because of its variable-speed trigger, you can easily control the grease flow. Furthermore, the design is absolutely stunning. Not only it looks good but it’s also designed in a way that makes it convenient and easy to use. Just take a look at the handle. Its ergonomic handle with a rubber grip makes things really easy for newbies.

  • Well-designed and durable.
  • Controlling the grease flow is as easy as it gets.

Grease Gun Buying Guide

Before we talk about our recommended products, let’s talk about the methods you should use to buy a grease gun. So, what should you know before you decide to buy a grease gun? At first, need to know some of the basic stuff and then learn about the technical details. Overall, you’ll need to be extremely cautious before buying a grease gun. Let’s talk more about it-


Before buying a grease gun, you should know which company manufactured it. This is something that most people do. If you buy something produced by a prominent company, it will be a good product more often than not. It’s a fact. Most well-known brands want to make sure that their reputation is intact. That’s why most of the products they make are good.

Online Customer Reviews

These days, customers or rather consumers do have a strong voice because of the internet. People do tend to share their thoughts about any product. So, it won’t be a bad idea to take advantage of that. Before you buy a grease gun, make sure to check out how people reviewed it. See whether they loved it or hated it. If they hated it, then check out why they had hated it. That way you can filter out a lot of products.


So, you buy a grease gun and after using it for a couple of days, you notice that there are some issues with it. So, what can you do? Well, this is where a credible warranty can help you out. before buying a grease gun, you need to make sure that it is backed up by a warranty. Good brands, that have a solid track record, usually offer that.

Pressure Rating

Now, we are going to get into the technical stuff and the first thing we need to talk about is the PSI. Inside the grease gun, you have grease and that grease needs to come out of the gun easily. For that, it needs to have a high PSI. The higher PSI a grease gun has, the more easily the grease will come out. A grease gun should have at least 6000 PSI. That’s the bare minimum.

Hose Length

The longer the hose, the easier it is to use. The hose should be at least 18 inches long. It’s better if the hose is longer because you can have the access to the “hard-to-reach” areas


The durability of any product is important. So, you must make sure that your grease gun is durable. For your grease gun to be durable, it has to be made with durable material and steel is the most durable material you’ll find. Most grease guns will have steel in them.


Many people think that the handle of the grease gun is not really that significant. But it is extremely important because the convenience of a grease gun depends on its handle.

That begs the question- what kind of handle is ideal for a user?

Well, it’s not a trick question. A grease gun should have an ergonomic handle because that is the sort of handle that is easy to hold.

Electric or Manual- Which one to buy?

By and large, you’ll find two types of grease guns. You’ll find grease guns that are run by batteries and at the same time, you’ll find manual grease guns. So which one should you buy? This is an important question. Grease guns that need batteries are actually suited for professionals who need to work with a grease gun daily. Manual grease guns are usually for DIY enthusiasts. 

Some FAQ about grease gun

If you want your questions about grease guns answered, just ask below in the comment section! We will do our best to answer ASAP.

How to use a grease gun?

Basically, you’ll have to push the handle to pump the grease from the barrel to the hose or tube. That’s the simplest way to describe it. For the long-form, it depends on what type of grease gun you own. No matter which one you have, all grease guns basic is same. You have to load the barrel with a grease cartridge or the other options your gun allows.

How to put grease in a grease gun?

At first separate the barrel and the head. Then pull the follower rod all the way to the back to ensure that it’s securely snug. After that, you need to put the grease cartridge into the barrel. There are two sides of the grease cartridge- the plastic side and the cap side. Make sure to store the grease cartridge cap side down. Then remove the cap and put back the barrel and head together.

How to load a mini grease gun?

The process is similar to a normal grease gun and we actually talked about it already. Just separate the barrel and the head, pull the follower rod, insert the grease cartridge and connect the barrel and the head.

How to load a grease gun without a cartridge?

The thing is there is a way to load a grease gun without a cartridge. But we do not recommend it because it’s easier to use a cartridge instead. But if you do want to know, then we can tell you.
Basically, you can implement the suction loading method where you have to partially submerge the open end of the tube assembly in an open container of grease. At first, you’ll need to clean the grease gun. Then you have to insert the open end of the tube assembly into the open container of the grease. After that, slowly pull back on the T-handle and draw the grease.

How to attach grease gun to zerk fitting?

Fit the extension hose with a coupler. You will see a 4-jaw construction in the coupler. Because of the design of the coupler, it will work well with both standard and metric zerk fittings. So, all you need to do is to put the zerk fitting inside the coupler. Then turn the coupler and you are done.

Is a battery grease gun worth it?

Depends on you. If you need to have a portable grease gun all day long, you do need one. But if you are just a DIY enthusiast, then it will be a complete waste of money.

Does lubricating grease go bad?

Of course, it can go bad. If you do not use it for a long time, then it will ultimately be unusable. If you store the grease container outside, then it will eventually accumulate dust or water on the lid which is not good for the grease. After some time, you won’t be able to use the grease. After buying the grease container, you should use the grease as early as possible.

All of them have their own advantages and disadvantages. We made sure that we have a wide array of guns on our list. That way you can pick the one that suits you.
