    • Good and so much better than manual greasing.
Style: Grease Gun Only
Amazing to have electric power over fighting with hand held manual method. Takes so much of the guess work out. Yes reviews are correct lack of light and the hose it too short. Priming is fast and easy. Made greasing 2 vehicles in no time while it was cold outside. Worth the upgrade. Still was questionable on the tight fit of toyota 4x4 driveshaft. Not entirely sure it went in. Might consider a lube lock head upgrade later on. ... show more

    • Makes Greasing Simple: Just Squeeze and Go!
Style: Grease Gun Only
This grease gun has made the chore of greasing my tractor and implements significantly easier—it's as simple as squeezing the trigger! The unit works well, and the included DeWalt fitting performs exactly as expected. I did purchase a separate tip (not yet installed) that looks like it will be even more user-friendly, but honestly, the tool is already a huge time-saver right out of the box. Highly recommend this grease gun! ... show more

Review Image by Jessica Jessica
As any DIY enthusiast or professional mechanic knows, greasing up machinery and equipment is a necessary chore. But with the DeWalt DCGG571B, it’s a chore that gets a turbo boost. Here’s why this grease gun deserves a nod: Performance: The DCGG571B is like the Usain Bolt of grease guns—up to 50% faster than manual ones. No more cranking that handle until your arm feels like spaghetti. This cordless wonder delivers grease with the efficiency of a well-oiled machine. Battery-Powered Convenience: It runs on DeWalt’s 20V MAX batteries—the same ones you use for your other DeWalt tools. Pop in a battery, and you’re ready to grease. No cords, no fuss. Pressure and Volume: Need power? This gun cranks out up to 10,000 PSI (that’s a lot of pressure!) and delivers 5.0 ounces of grease per minute. Whether you’re lubing up heavy machinery or your trusty tractor, it’s got the muscle. Smart Design: DeWalt thought this through. The innovative pump filter screen keeps dust and debris out of the pump mechanism, prolonging the tool’s life. Plus, the 42-inch hose lets you reach tight spots, and the built-in LED lights illuminate dark corners. User-Friendly Features: The no-mar foot design means you can rest the gun on flat surfaces without leaving marks. And when you swap cartridges, the air bleeder valve makes priming a breeze. Weight and Warranty: At 9.5 pounds, it’s not feather-light, but it’s manageable. And DeWalt’s got your back with a 90-day money-back guarantee, 1-year free service, and a 3-year limited warranty. ... show more

    • Great grease gun

Works great. Get a quick fitting for zerk fitting or youre gonna be pulling a lot. Super quick and no hand pain from pumping.

    • Ease of use
Style: Grease Gun Only
I watched a video online on how to use my Dewalt grease gun, which made it easy to load my gun and use it. First time out, I was able to grease my tractor and excavator in less than 15 minutes. Doing this with a manual grease gun is a lot messier and slower. My first impression is that this is a great tool. ... show more

    • Great product but heavy
Style: Grease Gun Only
I bought this product because I trust the name dewalt and it didn’t let me down. It works flawlessly as I expected. Now understand this unit is heavy for what it is but the hose is long enough you can sit it on the ground and still use it. So why the 4 stars. I bought and quick connect adapter to go on the end. I tried everything in my tool box to take the end off but never did succeed. I endured up buying a completely different hose so I could use the adapter. I’m not sure as to why it would not come off. It was like someone had put it on with lock-tight. . ... show more

    • Makes greasing equipment easier.
Style: Grease Gun Only
If you have a lot of greasing to do - maybe bought a tractor and 3 or 4 implements to go with it, and the tractor has a loader and a bucket or forks on the front of it so you have a LOT of zerks to grease, a gun like this makes the job a lot easier. I went with Dewalt because I have the batteries, and so far the DeWalt gun has worked great. Easy to load, easy to use, no issues. ... show more
