DeWalt DCGG571M1 | Cordless Grease Gun

Greasing shafts, ball joints and bearings by hand can become time-consuming. This is especially true if you’re using large equipment with a lot of moving parts. If you have a workshop, are a farmer with a number of mechanized implements or even a DIY homeowner with gardening tools and vehicles that need regular greasing, an electrically powered grease gun will certainly make your life a lot easier.

These days, battery power is the way to go. Cordless power tools are so easy to use and very convenient. With major improvements in both battery and electric motor design, these tools now offer much longer working times than older versions.

The DeWalt DCGG571M1 cordless grease gun is a fantastic tool for the job and is very reasonably priced. Considering that it comes with the DeWalt reputation for quality and innovative design, it’s hard to find anything in the same price range that compares. It forms part of their 20V Max range of battery operated tools and shares the same battery with more than a hundred other quality DeWalt tools.

What’s even more impressive is that it’s able to use the new DeWalt FlexVolt battery which offers up to five times more working time than their older batteries. We’ll compare the DeWalt DCGG571M1 with its closest rival, the Lincoln Lubrication 1844. The Lincoln costs quite a bit more and is another quality item that may have a slight advantage over the DeWalt. Is it worth paying extra for the Lincoln when the DeWalt DCG571M1 does very much the same job? Only you can decide on this. After reading our review of the two options, you should be better able to make the distinction and be able to make an informed decision.

DeWalt DCGG571M1 | Cordless Grease Gun

Features:

• Powerful motor delivers 10,000 max psi to power through clogged grease fittings.
• High-volume pump pushes up to 5.0 oz/min high-flow applications.
• Up to 16 cartridges per charge with a single DEWALT 20V MAX Battery (4.0 Ah)
• Variable speed trigger offers precise control of the grease flow
• 42″ extra long and flexible hose designed for reaching hard to access grease fittings.
• Bright LED light assists in locating hard to see grease fittings in low-light situation
• Innovative pump filter screen prevents dirt and contamination from clogging the pump mechanism.
• Integrated no-mar foot design allows operators to rest the tool on flat surfaces
• Air-bleeder valve assists in pump priming after cartridge changes

The familiar sight of the DeWalt black and yellow branding always gives me a sense of confidence. So, from the start I’m impressed. Please forgive my bias toward the brand but I’m sure many will agree, it’s hard to find fault with DeWalt tools.

The DeWalt DCGG571M1 is extremely powerful. In fact, in some instances, it may be a little too powerful. So you should be aware of this when greasing sealed bearings where the seals can become damaged by the high pressure. What kind of pressure are we talking about? It’s able to push out 10000 PSI which is great at forcing grease through nipples that have become clogged by dirt.

Volume certainly isn’t a problem as it moves the grease at a rate of 5 OZ/min and a variable control trigger means that you have infinite control over the flow speed. So whether you’re greasing a small ball joint or a large prop shaft, you can decide how fast you push the grease through.

Using the 4AH 20V lithium-ion battery will allow you to work through up 16 cartridges on a single charge – it has a 14.5 OZ cartridge capacity. Changing the cartridges is made extra easy with a self-bleeding valve that helps to remove the air when priming.

At 9.5 LBS it can become a little heavy if you’re holding it one hand for a long time. Though this is not too much of a problem and it has a convenient shoulder strap. It also has a very nice base that allows it to stand upright when you place it down. This means that you can rest it on the ground if you’re working in a situation where this is feasible. With a really good pipe length of 42”, there are a lot of situations where this is possible. The pipe also has spring guards at the nipple fitting and at the gun body to prevent it from kinking.

One of the benefits of using an electric grease gun is that you have the benefit of a LED light that makes things easier when you’re working under a vehicle or any of those awkward places that one so often finds in these situations.

There can be no doubt that the DeWalt DCGG571M1 is an excellent piece of equipment and worth every cent of its very reasonable price. If I were to find anything lacking, it would probably be the fact that you can’t control the pressure, 10,000 PSI can be a bit high for some applications. Other than this, it earns full marks, just as one would expect from the brand. You also have the benefit of the DeWalt 3-year warranty, 1-year free service plan, and a 90-day money back guarantee. Service and spares for DeWalt equipment are a given and you can always expect the best when it comes to dealing with their agents.

Lincoln Lubrication 1844 / Review

Includes 2 batteries (NiCad) : Cordless grease gun

Features:

• Powerful high-torque motor
• 7,500 psi working output pressure
• 9 oz/min grease output at 1,000 psi (H)
• Air purge valve for immediate prime
• Check-ball accessibility allows easy cleaning of contaminated or hardened grease
• Slotted HD casting accepts shoulder strap
• 2-speed output selection
• High-capacity battery
• One-hour smart charger
• 30” high-pressure whip hose with spring guards and coupler

Overview

The Lincoln Lubrication 1844 may have a slight advantage over the DeWalt but, considering that it’s more expensive than the DeWalt DCGG57M1, I would expect something for the extra cash.

The Lincoln comes with a neat carry case which, in itself, wouldn’t make me want to pay extra for this one – but it’s nice. You also get two batteries as part of the kit. Even this won’t convince me to pay more for the Lincoln, the 18V lithium-ion battery used in this one, doesn’t quite compare to the DeWalt. With the Lincoln, you can expect to get about 10 cartridges to a battery charge. When compared to the 16 that one can expect from the DeWalt DCGG571M1, the extra battery is more of consolation prize.

Where I prefer the Lincoln Lubrication 1844 is that it has a 2-speed transmission. So you can choose to use it at high pressure with a lower volume when you need to push through stubborn dirt and old grease, or choose to use a lower pressure with a higher volume. The advantage of this only comes in when you feel that the high pressure might damage some of the seals on the item that you’re greasing. Otherwise, the high pressure of the DeWalt combined with a great volume is actually better for most situations.

When you’re greasing a heavy shaft, having both pressure and volume makes the job that much easier. Even at high-pressure, the Lincoln doesn’t quite push as hard as the DeWalt, the Lincoln has a maximum pressure of 7500 PSI.

If the DeWalt DCGG571M1 seems a little heavy for you, then this one won’t make you very happy. It weighs 16 LBS. In all other respects, it’s an even match between the two. The Lincoln also has a quality hose with spring protection. They don’t give specs for the hose length but from the measurements I’ve been able to get, it’s not as long as long the DeWalt. The Lincoln also has a LED light and has the added advantage of an LCD screen that gives you the battery status and tells you much grease is left in the cartridge.

The Lincoln Lubrication 1844 is, like the DeWalt, a very high-quality item and manufactured to excellent standards. Their 5-year warranty and 100-day satisfaction guarantee are proof of this. You can certainly buy this item with complete confidence.

DeWalt DCGG571M1 vs Lincoln Lubrication 1844?

If I were to choose between the two, I don’t think I’d consider it worth paying extra for a carrying case an LCD screen. So I’d probably go with the DeWalt, but I do usually sway toward DeWalt products when comparing them to most others. The only real disadvantage to the DeWalt is the high pressure which, in most cases, is an advantage. Though there may be some times when that pressure proves to be too much for sensitive seals.
