For the casual mechanic, this is likely more than enough power to get you through a majority of common fastening and loosening applications. And, it accomplishes all of this power and portability in a 3.3-lb. frame.

The Hart HPIW01 uses a friction ring for quick socket changes. An integrated LED work light lets you see what you’re doing, even when you’re under your hood or in a space where light isn’t optimal.

Our Thoughts

That 350 foot-pounds number seems to fall under “loosening torque”. Still, even a couple of hundred foot-pounds of fastening torque takes care of a majority of jobs you find in the amateur or hobbyist automotive world. A tool like this can remove most lug nuts from anything from cars and trucks to zero-turn lawnmowers. It also gives you the ability to drive a lug nut on until you hit the impact mechanism—and then finish with a torque wrench to get the exact amount you need.

While not a professional-level tool, the Hart HPIW01 20V impact wrench should find a wide appeal. The 3-year warranty doesn’t hurt either.


Pricing and Availability

Like the rest of the Hart 20V lineup of cordless tools, you can find the Hart 1/2″ Impact Wrench exclusively at Walmart. It’s sold as a bare tool, which lets you keep your options open for how much battery you actually want to commit to. You have a 1.5Ah, 2.0Ah, and 4.0Ah options available.

The Hart HPIW01 retails for $119, and it comes with a 3-year warranty.

I hate to say this but I may have to try this impact out. Majority of my tools are red and have impacts and maybe 60-70 percent of their offerings. But I also have some of the hart products. Mainly got just to check out and to have some spare power tools that I didn’t give two shits about on the job sites in case someone didn’t bring theirs or there way a new guy who still was tooling up (at the time my boss was bringing in guys who Didn’t have hardly anything for tools and most of them… Read more »
