Hart 20V Cordless Grease Gun

Hart Grease Gun Fleshes Out Cordless Line for Mechanics

The Hart line of cordless DIY tools continues to expand…and at this point, the 20V line has grown pretty deep. Case in point: the Hart 20V Grease Gun. This somewhat niche tool joins the lineup to simplify the process of greasing down your fittings.

What’s the Big Deal?

The Hart 20V Grease Gun doesn’t do anything that any other cordless grease gun doesn’t also do. However, the beauty of this product is that, if you’re already using the Hart 20V battery platform, you now have access to a pretty capable grease applicator.

It works with any 13.7 oz to 14.5 oz grease cartridges. And, with a max pressure of up to 10,000 psi, it can push up to 7.5 oz. of lubrication into your fittings in about a minute.

Like we said earlier, the Hart 20V Grease Gun doesn’t reinvent any wheels or anything. Or, to spin that more positively, it easily keeps up with other cordless grease guns on the market. And it does it on a battery platform that you can pick up by running down to your local Walmart.

We honestly had no idea Hart Tools would include specialty products like this but it indicates a move towards meeting the needs of a much wider group of users than we initially suspected. Best of all—it only looks like that trend should continue into the foreseeable future.

Other Features

  • 30″ flexible hose for easy access to various grease fittings
  • Integrated LED light for us with hard to reach grease fittings
  • Steel tube provides maximum durability


You can pick up the Hart 20V Grease Gun at your local Walmart or at the online store. Currently, it comes as a bare tool and retails for $119.

Very similar to Milwaukee’s.
We can clearly see that Hart tools are made by TTI
