DEWALTGrease Gun 20V MAX, Cordless Electric Grease Gun 42” Hose, 10,000 PSI, Variable Speed Triggers, Tool Only (DCGG571B)

At work 1 of the guys has a gun like this works great pushes through some plugged grease fittings easily. Sorry I didn't use my gun yet it is same so should be good

I wish I had bought this years ago. My tractor has a lot of grease fittings, this works great. So much easier than pumping the manual gun. The hose is just the right length. Even Zerk fittings that have dried grease, this gun has enough power to purge the dried grease. I recommend changing the coupler with one that has a lever to lock and release it. I first purchased a cheaper off-brand grease gun and returned it for a better quality (Dewalt). Dewalt has an over-pressure relief valve! If you have a clogged Zerk fitting the over-pressure relief protects your hands from a burst hose (an important safety issue). I wish it had a place to park the grease fitting when not in use.

Frankly, you can get by with a much lesser grease gun than this, and it would probably be tough to justify for anybody but a well equipped professional or a really hard core do-it-your-selfer. This thing was not cheap.....Having said that, anybody who has spent anytime under a car, truck, or RV trying to grease hard to find and access grease fittings knows the frustration of trying to keep the coupler from going crooked or popping off altogether from a difficult fitting, all while trying to pump the gun in a confined space. For me it usually results in grease leaking out everywhere and neighbors closing their windows to avoid the profanities.This gun changes all that. Some have called it a game changer, and they may not be wrong...After one particularly hot, sweaty, frustrating job where I ended up trashing 4 non-working-at-the-time, cheapy to not-so-cheapy conventional chinese grease guns and 2 air operated china guns I decided to break down and buy something decent. (I don't know...Is Mexican made automatically better?)I'm already married to the Dewalt 20v/60v stuff, so choosing a brand was pretty much a no brainer.So, in for a dime, in for a dollar.....I also bought and installed a LockNLube coupler right out of the box along with a LockNLube 90 degree coupler for use when necessary. (The LockNLube coupler simply clips firmly to the 90 adapter. Too Cool....) When using the straight coupler, if you can get the coupler on the fitting, it's not coming back off until you want it to. When using the 90, you may have to hold it in place, but that's a whole lot easier when you don't need 3 hands like you do with a pump gun. (The LockNLube is killer, and probably 50% of what makes this rig great. I personally wouldn't get one without the other.)I was always disappointed with both of my air operated, hand held grease guns. They worked well on most fittings, but it seemed like every job had at least one plugged fitting the air powered guns couldn't handle, resulting in having to go sift through my tub full of oil dripping, old conventional grease guns in hopes of finding one that works well enough to to bust through the dirt/dried grease. Not so with the Dewalt. I have yet to encounter a fitting it couldn't blast through. I read a review of someone who claimed the opposite, that their gun couldn't push grease through much of anything without the relief valve popping off. I'm pretty sure that had to be a defective unit. I have been a mechanic for about 45 years now, and this is easily the strongest gun I have ever used.Overall I can usually finish in a fraction of the time, without all the frustration. It's worth every damn penny to me.......

Love this grease gun,makes a choir feel fun.

Works great

Works great and it’s fast and easy to get into small places

I really didn't want to spend this much money on a grease gun, but I bought a tractor and I really didn't want to hand pump every fitting on all the attachments. I already have Dewalt tools and 20V Batts, so I made the jump. 100% happy with this decision. I greased the tractor and all attachments in under 15min using 1.5 tubes of grease. It primed immediately, every joint had grease push out both sides and my hand doesn't hurt. This brings a chore down to a quick task and I'm positive my tractor will age slower due to this purchase. I do have other items to use this on. If you only have one or two things to grease maybe once or twice a year, use the hand guns. If you have 10 fittings or more with regular need this tool will make a real quality of life improvement for you and encourage you to grease things proactively.
