Best Cordless Grease Guns

Cordless grease guns are powered by batteries. They are convenient to use and are usually among the most powerful grease guns. They are able to inject grease at high pressures which is not possible using a standard pneumatic or other kind of grease guns.

Best cordless/Electric grease guns

Here is the list of the best cordless grease guns

  • DEWALT DCGG571M1 20V MAX
  • Lumax LX-1175 Handyluber 12V Cordless Grease Gun
  • Milwaukee 2646-20 M18 2-Spd Grease Gun
  • Lincoln Lubrication 1242 12 Volt DC Cordless Rechargeable Grease Gun
  • Alemite 596-A1 Battery-Powered Grease Gun

1. DEWALT DCGG571M1 20V MAX

This is the most popular of the electric grease guns listed in different marketplaces like Amazon, Home Depot etc. It is powered by a 20V Li-on battery that can last up to 16 standard size cartridges, that’s a long time. It delivers up to 10000psi of pressure and has a flow rate is 5oz /minute which is more than that of many competitors.

Its variable speed trigger allows operation at different speeds. The anti-debris mechanism it has keeps the pumping mechanism from damages due to dirt. It also has an LED light which can be used for greasing dark parts of a machine. It comes with a 42” long flexible hose which is ample. The package comes with a shoulder strap, a fast charger and a kit box. The Dewalt cordless gun is covered under a 3 year warranty with 1 year free service.

2. Lumax LX-1175 Handyluber 12V Cordless Grease Gun

The Lumax LX-1175 is powered by a 12V battery (1500mAh). It is not as solidly built as the Dewalt gun mentioned above but both are vastly different cost wise. The battery once charged to full can last up to 5 standard sized cartridges of grease. It can build up to 7000psi of pressure and deliver a flow of 3.5oz per minute.

This is definitely the cheapest electric grease gun in my list. Costing around 100 bucks this also comes with a 30” flexible hose, a 1 hour fast charger and a carrying case. It is light-weight and easy to handle. It also has a 1 year warranty for manufacturing defects.

3. Milwaukee 2646-20 M18 2-Spd Grease Gun

This electric gun can produce up to 10000psi but they haven’t mentioned its flow rate anywhere. It has a 2-speed trigger suitable for fast/slow grease delivery. One notable feature is a pre-set greaser counter. This is a patent pending feature that allows users to dispense a preset amount of grease; this really comes in handy for newbies and professionals alike.

It uses an 18V battery which has a run time of upto 10 standards size cartridges in one go. It also comes with a shoulder strap, LED-light and a 48” flexible hose. It also has standard features like air-bleeder and a lock on/off trigger. The plunger rod with markings indicate how much grease is left in the barrel, this is also a useful feature to many. Its grease flow rate is 10oz/minute, that’s more than any other electric grease guns I reviewed here. This grease gun is covered under a 5 year warranty.

4. Lincoln Lubrication 1242 12 Volt DC Cordless Rechargeable Grease Gun

The Lincoln electric grease gun is powered by a 12V battery. It can deliver grease at a pressure of 6000psi. A 30” flexible hose that comes with the unit helps to deliver grease to less accessible locations of a machine. It can accommodate a standard 14oz grease cartridge. It can also be loaded by bulk or grease pump.

A 110V fast charger and a carrying case with extra slots for an additional battery and 2 cartridges are included in the purchase. This machine is covered under a 1-year warranty.

5. Alemite 596-A1 Battery-Powered Grease Gun

This cordless grease gun is the powerful of all. With a 20V (2500mAh) Lithium-ion battery it delivers up to 10000psi of pressure. It can deliver 6oz of grease per minute. What is interesting is that you can adjust the flow rate. There is a low-flow rate setting which limits the grease flow to 4oz/minute and a high-flow setting which allows 6oz/minute flow.

Its battery is super long lasting. It can last up to 23 grease cartridges for high speed operation and 24 for low speed setting. This is also more than that of any other cordless guns I checked. Its patented automatic follower makes grease loading easier. This can be filled via cartridges, in bulk or by pump.

In addition it has a grease meter, cartridge level indicator and battery capacity gauge all displayed via an LCD screen displayed on the handle. The grease gauge reading can be seen in ounces and grams. The LCD screen turns red if there are any problems like stalling, low battery or low grease levels. I should say it is pretty convenient.

 It has an LED flash light for easily greasing dark areas, the patented air-flow technology increases battery and motor life. And this grease gun is covered by a 5-year warranty! (The battery and the charger are under 2-year warranty)
