Should I Choose a 3/8 or 1/2 Stubby Impact Wrench for My DIY Projects?
Asked by CraftyElephant77
I'm planning to buy my first stubby impact wrench during Ohio's no sales tax holiday, but I'm stuck on whether to go with a 3/8 or a 1/2. I don't have any impact sockets yet. I've heard that a 3/8 might be cheaper, especially since it uses smaller sockets, but I also think it could be convenient to only need one socket set when I eventually get a 1/2 M18 impact. Most of my work will be DIY on a 1949 Packard and some tasks on my daily vehicles. What do you all think?

I vote for the 1/2 impact. The thing is, a lot of 3/8 socket sets max out at 22mm, so if you're planning on tackling bigger jobs later on, the 1/2 will cover you better in that regard.

If you're looking to save some cash, the 3/8 impact is the way to go. It not only costs less, but also means cheaper socket sets. Plus, both sizes pretty much accomplish the same tasks for DIY projects.

Honestly, if you can swing it, having both is the best option. I use my 3/8 for everyday tasks and pull out the 1/2 for the heavy stuff, like truck rims or suspension work. The 3/8 is tough and reliable for daily use, and it’s super versatile!

I just worked with some mechanics at a shop, and they mainly stick to using regular chrome sockets even with their impacts. They only roll out the 1/2 impacts for heavy-duty work like suspension parts, so you might find you don't need the 1/2 as much as you think!

The M12 3/8 impact is a solid choice for most tasks. If you sometimes need a stronger tool, just buy the specific sockets for those heavier jobs. I use adapters to switch between sizes, which works great! Also, check out Astro's 'nano' impact sockets; they're a perfect fit with the M12.
