In order to avoid dry friction, lubrication is applied to the moving parts with a grease gun. However, overeager novices might be inclined to grease (and over-grease) everything. That’s not what you need. Over-lubrication brings its own set of problems. It attracts dirt and grime, and it makes everything messier than needed.
Grease guns come in different shapes and sizes; There are four types available — cordless, pistol grip, lever, and hand pumps — all manufactured for different purposes.
The Best Grease Guns
1. DEWALT Cordless Grease Gun
Dewalt's grease gun tops our list for all the right reasons.
For starters, it’s able to deliver grease of up to 5 ounces per minute. Talk about high-flow! And not only that — it’s armed with a potent motor that can generate a maximum of 10,000 PSI of pressure, which makes it easy to go through all grease fittings. So, if you have a clogged fitting that’s making your life hell — this grease gun is a good solution.
Another handy feature is it's fitted with a bright LED light, which is not that common in these tools. It helps you to locate hard-to-see areas, and you can also use it in low-light settings. It’s also equipped with a 20V MAX XR Premium Li-Ion (4.0Ah) battery, which allows up to 16 cartridges per charge.
What’s more, the handle has a nice grip, and the gun comes with an extra-long and flexible hose (42 inches) attached to it. So, you don’t have to twist your arm at impossible angles to reach those secluded areas. There’s also a variable speed trigger that will give you more control over what you’re doing. You can then easily adjust the grease flow. Both these features ensure maximum precision.
This grease gun delivers lubrication with as little mess as possible. It even has an integrated no-mar foot design. It allows you to put the grease gun down without it tipping over and spilling the grease.
2. Milwaukee Cordless Grease Gun
The first thing you’ll notice about Milwaukee M12 is that it has an ergonomic handle. If you’re wondering why that’s the first thing you’ll notice, the answer is — no cramping! The handle is ideal for prolonged use.
What’s more, the entire gun weighs only 7.2 pounds. Compared to some other grease guns on the market, it’s light as a feather, so it’s perfect for those who need to use it often or for longer periods at a time.
Upon applying full pressure, this grease gun has the ability to deliver over 8,000 PSI for a heavy-duty application, and it can deal with a maximum of seven cylinders per charge.
However, the best feature of this beauty is the additional equipment. It comes with a grease coupler, a carrying case, a 30-minute charger, an M12 XC battery, and a flex hose.
Furthermore, the integrated fuel gauge and hose storage increase productivity and ensure there’s less mess to clean up afterward.
The gun is quite durable, even though it comes with a five-year warranty. So in a nutshell, M12 12-Volt is one of the better options available. It’s simple to operate and surprisingly efficient.
3. Lincoln PowerLuber Grease Gun
When it comes to cordless grease guns, the Lincoln PowerLuber is your best bet.
Lincoln's PowerLuber can deliver pressure up to 10,000 PSI high, which makes it ideal for heavy-duty uses. It comes with a two-speed grease output digital selector. You can easily shift from high-volume to low-volume, dispensing the grease with just a simple click of a button.
Still, what caught our attention is its digital display. It shows grease output rates, battery life, and alerts for any blocked fittings. So, it does half the job for you. It’s as much a diagnostic tool as it is a lubricating tool.
The PowerLuber comes with a three-point base, designed to keep the tool stable on flat surfaces for easy handling and cleaning. And you can’t ignore the built-in LED lights either. These can have a huge impact on your productivity because now those late nights in the garage will be much more effective.
4. Alemite Pistol Grip Grease Gun
If you’re not interested in traditional grease guns, then you should definitely consider the Alemite 555-E. The innovative features make the whole lubing process convenient and practically effortless.
The Alemite 555-E Pistol Grip Grease Gun comes with a dual mode lever that allows you to use it in a few different ways. You can either choose to have high-pressure delivery or high-volume output — whatever you need at that moment. The cylinder can generate up to 7500 PSI, which is more than enough to carry out heavy-duty applications. Furthermore, it can hold 16 oz of grease but weigh less than 4 lbs.
Another notable feature is the way you can load up the gun with grease. Generally, these guns either allow bulk loading or the use of a grease cartridge, but this gun offers both options.
As you know, putting extreme pressure on a device can lower its longevity. So it’s natural that you’re worried about the lifespan. Grease guns are big investments, and it’s important that you choose one that will be handy for years to come. You don’t have to worry with the Alemite 555-E. It comes with a bleeder valve that ensures our one-time investment lasts you for years.
5. GreaseTek Pistol Grip Grease Gun
Pistol grip grease guns are not only durable but easy to handle. They are also quite reliable. So, what’s the issue? The price. If you want a good grease gun but don’t want to blow a hole in your wallet, go for the GreaseTek Premium Pistol Grip Grease Gun.
It can carry up to 400cc of grease and apply 1oz per 40 strokes. Furthermore, it has an 18” hose that comes with a coupler, which makes adding some grease in the tiniest corners not just possible but effortless too.
In addition, the device also offers you full control over the grip while operating it. The knurled barrel doesn’t allow the gun to slip out of your hand.
However, there’s one downside to this device — you may have some issues with the fittings. The cartridge size isn’t as big as with other grease guns. So, if you need a suitable gun for small jobs, then GreaseTek Premium is an adequate choice. However, if you need it for massive machinery, you might want to look elsewhere.
It also doesn’t look as impressive as some other grease guns on our list. But for an affordable product, and despite the downsides, it still has a lot to offer. In fact, its dual-positioning grease loader gives us more options when it comes to operating the device.
What to Look for in a Grease Gun
Before you pick a grease gun there are several things to consider. To start with there are 4 different types. Next you need to determine if it has enough power for the machinery you're working with. Lastly, ease of use and purpose.
Types of Grease Guns
As mentioned earlier, there are four types you can choose from:
Lever grease guns are the most popular and readily available. They are user-friendly — you simply have to stroke the lever for the grease to come out. You can also control the flow as well as the pressure by altering your stroke length. However, these are only suitable for lighter applications.
As the name says, pistol grip grease guns are quite similar to pistols in terms of design. So you only need one hand to use them. Position the device on the target area and pull the trigger to release the grease — it’s that simple.
It’s great even for lefties, which is a commendable feature. As many left-handed people know, not all tools are ambidextrous. More importantly, pistol grip guns are ideal to use in confined spaces where you can’t fit a bigger device.
When you use multiple corded tools, it’s easy to get all tangled up. In order to look like a proper mechanic opt for the cordless, portable grease guns. They won’t restrict your movements, and they will dispense the grease easily. No need to grip the pump like a maniac — a light push will do just fine.
These types of grease guns come equipped with small, portable pumps. In order to make them work, you have to use the pump to build pressure so that the grease comes out.
Hand pump grease guns are quite powerful and versatile. However, they are not the easiest to handle, which makes them the least favorite choice of “amateur greasers.”
Ease of Use
There are a few things that can make a grease gun user-friendly. Look for a long, flexible hose if you want to lubricate tough-to-reach areas or an anti-slip rubber barrel sleeve that’ll make handling the device and changing the cartridge easy.
Fitted LED lights can help you grease at night too, so make sure the gun has those as well.
