A grease gun is a tool used in the garage or workshop that is used to transfer lubricating material (usually grease) to certain components. Working with grease is a messy and smelly job, not to mention slippery. When you’re working with delicate components, it’s best to keep your hands or gloves clean; having grease all over your hands may contaminate the parts and affect the overall output of your work. To keep things tidy and comfortable to handle, you can use a grease gun as a dedicated container for grease instead of using a tub and slathering your hands with the messy stuff.
If you’re saying that grease guns are simple and don’t need a lot of technology to work, you’re wrong. Grease applicators are the simple kind of grease guns which can contain grease and a simple pump. The pump allows you to push out the grease in the reservoir like how you would pump out the lotion from its bottle. Real grease guns often use powerful motors to pump out the grease instead of a manually-operated pump. These motors allow you to push out the grease with constant pressure that gives you the ability to push out the old grease and replace it with the new one. This feature saves you time from disassembling the part and scrubbing out the old grease.
Grease guns usually come as wired tools or wireless battery-operated. Both tools work the same, but the battery-operated cordless grease gun gives you the benefit of mobility around your working area. Check out this compilation of the best cordless grease guns you can buy today.
DeWALT DCGG570B 18V Cordless Grease Gun
The powered grease gun saves you time in the application of grease on components. The DeWALT DCGG570B Cordless Grease Gun uses a powerful motor to achieve a maximum pressure output of 9000 psi; this powerful output allows you just to push out the old grease that’s inside the fitting and replaces it with the new one. It gives you the benefit of saving time from removing much of the disassembly required for cleaning.
The grease gun is powered by an 18-volt battery that is used to power the powerful motor. Using an electric design, you can take advantage of variable speeds thanks to the trigger mechanism of the grease gun. The reservoir included is a machined steel canister that can handle tremendous amounts of pressure from the motor. The pump can achieve a high flow of up to 5 ounces per minute which is high enough for grease gun standards.
The machine comes fitted with a long 42-inch ultra-durable and flexible hose. This hose is designed to handle the extreme pressure of the grease while keeping the grease flow rate constant. As a touch of convenience, the tool includes a bright LED light for lighting up dark spots on a part. The machine can be used either in wired or wireless modes. You don’t get a battery in the package so unless you order a battery; this tool can’t be used right out of the box.
Lincoln Lubrication 1244 PowerLuber 12-Volt Cordless Grease Gun
The Lincoln Lubrication model 1244 PowerLuber is a complete package right after you order it. The kit comes in a durable Pelican case the houses everything you need from the tool, the battery, and the charger. The whole package includes an extra 12-volt battery which you can use to quickly replace the pre-installed battery if it runs out while you’re working. Also, you don’t need to worry about running out of batteries; the included charger is a quick charger which means you can juice up a spare battery quickly.
The grease gun itself uses hard plastics and metal for its construction. The plastics keep you away from the risk of electrocution from the powerful motor and the metal components ensure that the crucial parts are made with durability and heavy-duty in mind. The grease gun is fitted with a 30-inch rubber hose with an integrated spring flex guard which improves the strength of the hose. The motor’s smooth running is ensured by using a 2-inch needle bearing final drive.
While the grease gun is more expensive than the DeWALT, it only has a maximum output pressure of 6000 psi; however, the DeWALT comes as a tool only; the extra cost of the Lincoln Lubrication 1244 PowerLuber comes from the extra batteries, charger, and carrying case. 6000 psi is decent enough for most applications, so you’re not losing much in the power department.
Lincoln Lubrication 1242 12-Volt DC Cordless Rechargeable Grease Gun
The little brother of the Lincoln Lubrication 1244, the model 1242 is mostly identical to the 1244 with the difference being the 1244 is the newer model. The 1242 uses a 12-volt motor that gives you a maximum pressure output of 6000 psi, this is good enough for most applications and is faster and more effective than manual application methods. The cylinder and hose are designed to keep grease in and the air out. It results in consistent output that’s free from air pockets that may affect the overall quality of the craft on the part.
You can give high praises to Lincoln Lubrication’s designers for making a comfortable tool to use. Instead of orienting the motor horizontally like most power tools, the motor for the model 1242 PowerLuber is positioned vertically to provide a balance in weight. What this means is handling the 1242 more comfortable compared to grease guns with a standard design. The machine uses the same mix of hard plastics and high strength metal components for heavy duty use. The battery used is a 12-volt Nickel Cadmium rechargeable battery that is compatible with Lincoln Lubrication’s quick charger. The grease canister is fitted with a machined steel and hardened piston to improve the durability.
The whole package comes with a custom carrying case where you can keep the grease gun and enough room for a spare battery and extra grease cartridges.
Milwaukee 2446-21XC M12 12-Volt Cordless Grease Gun
If you’re looking for a long endurance grease gun with a powerful output, you can’t go wrong with the Milwaukee 2446-21XC M12 (what a mouthful) Cordless Grease Gun. The grease gun is designed to be compact and easy to use. The footprint of the grease gun is smaller than most grease guns of its class, and this makes for easy storage and handling. Instead of putting the motor along the handle or like a pistol, the designers are Milwaukee put the motor right next to the grease canister. The result is a stable design that changes the way you hold grease guns.
Instead of holding the grease gun like a typical power tool such as a drill with its pistol-like ergonomics, you hold the Milwaukee Grease Gun horizontally and allow the weight of the motor and grease canister to hang vertically. This way, you can hold the grease gun like a bag and just let the weight hang from your fingers, no more aching wrists after extended periods of time using the grease gun. Speaking of long periods, the 12-volt battery on the grease gun can squeeze all the grease from up to seven grease canisters on a single full charge; and this is done with an 8000-psi power output. Talk about efficiency!
Neiko 12000A 12V Cordless Grease Gun
The Neiko 12000A is the by far the lowest priced grease gun on this list. If you’re looking for something affordable, the Neiko 12000A is the best choice for you. What makes this grease gun one of the best, is because of how it maintains affordability while still achieving a relatively robust power output. Apart from performance, there’s also value in the overall package of the grease gun. For the price of only a portion of big brand grease gun’s total cost, the Neiko 12000A includes a carrying case, a spare battery, and a charger for the batteries.
Everything sounds too good to be true right? Well, the grease gun comes with a few quirks. First of all, the build quality is on the questionable side. The first inspection of the tool reveals that is mostly made of plastic apart from the grease canister. This plastic build is one of the major reasons why this tool costs so cheap. The other steel components are found on the motor and the grease canister fittings. Apart from that, everything else is ABS plastic.
The charger that’s included is a quick charger that gets your batteries juiced up in an hour. The 1300mAH capacity batteries are enough to go through a few canisters, and the setup includes a smart vent valve to eliminate air pockets from the system which ensures a stable flow of grease from the machine to a particular part.
If you’re working on a car, motorcycle or any other job that requires some lubrication, grease guns are your best friend. Not only do grease guns keep your hands clean when working on components, but these also save you time compared to working with manually pumping grease from a grease applicator, or worse; getting your hands dirty with a tub of grease. If you’re looking for a grease gun, you only need to consider the best value for your money; get a grease gun that’s decently priced and has a solid build. Apart from all of that, as long as you care for it, grease guns are relatively durable.
