Tekamo 1/2" Impact Wrench, HIGH Torque & Compact Package Combined
Written by Luis Montes Updated On October 30, 2026
The Tekamo 1/2" XS impact wrench is among the best stubby pneumatic impacts on the market, thanks to the combination of its ultra-short compact head, high torque, and neat directional change switch location and design.
Granted, cordless impacts are more versatile. However, they are bulkier than air impacts and, as of 2026, still can’t match pneumatic torque power. So for bolts in really tight spots (especially when corrosion is at play), where long tools aren’t an option, the Tekamo 1/2" stubby impact wrench will prove to be a worthy addition to your toolbox.
In this article, we’ll highlight the tool's key features, compare it with similar stubby impacts, and share results from cordless vs. air model comparison tests showing that the latter delivers more power.
Tekamo 1/2" Stubby Impact Wrench Features
The Tekamo 1/2 XS impact wrench is tiny, in a good way.
Despite its 4.5" head, it can generate 500 ft-lbs of tightening torque and up to 811 ft-lbs of loosening torque.
We like that the power-control wheel and directional-change switch sit right behind the trigger, making this impact wrench a true one-handed tool.
However, our favorite feature is the two opposite levers on the directional change switch, letting you choose between forward and reverse with both thumbs instead of awkwardly using your index finger.
Impact Force Values Comparison
As you can see in the table below, compared to the competition, the Mueller Kueps 1/2" XS is an overall well-rounded option: compact and powerful, with easy-to-reach, one-hand operation controls.

Can Cordless Impact Wrenches Replace Pneumatics?
Not in the context of this article, that is: being able to deliver high torque in tight spots.
As we mentioned at the beginning of this post, cordless impacts are not as powerful as pneumatic impacts, at least for the time being, especially on reverse torque. Here are the results from an online test in which the Milwaukee 2855-20 M18 FUEL 1/2" (a very popular cordless stubby) is compared against several 1/2" compact air impact wrenches:

Conclusion
The Tekamo 1/2” Stubby impact wrench design balances size, power, and user controls to craft an air tool that can deliver up to 811 ft-lbs of loosening torque in hard-to-reach spaces.
Although cordless impact wrenches are more convenient, they aren't as powerful or as compact as stubby air options. If your excuse is that hauling a hose is inconvenient, swivels and whip hoses greatly solve this problem.
If you’re looking for a stronger option without sacrificing compactness, the Tekamo 3/4" impact wrench qualifies as a stubby version despite its larger drive. We have an article that reviews its features and compares its size to similar models from other brands. Don’t miss it.
