[Product Review] TEKTON Manual Impact Driver 

That's why these are great for screw removal. Aircraft maintainers have used them for many decades on panel screws.

@@obfuscated3090 I just got one and it's a clever design. The impact on the back pushes the bit into the screw really well just as it turns.

Better still, leave them out. The lug nuts do the job just fine.

this tool provides a downward force as well as a turning force. the cordless impact just provides turning force. even if you push the cordless as hard as you can into the stuck screw, the manual impact driver will be stronger downward. also, you're very likely to break bits with the cordless because it's got so much more torque.

precision / fine control. The same reason you likely still own basic screw drivers alongside power tools.

Go ahead use your cordless impact on a rusted/seized philips head and after you strip the head or break the the bit you'll understand why you need one.

for hard to remove one, i use manual allen key, impact cordless, and impact wired , cant open and the allen key head become loose, i use this tools and it unscrew without much effort. use it on my bike rusty brake disc screw. i just use the made in china one, cheap.

@@pizza_bootySo basically, grab your hammer drill instead. (Commonly used in other parts of the world cause everything is build out of brick and concrete) Most west Americans don’t know what that is so they use those manual tools their grandparents had. 😂 This is why you will ever see them used for mechanics since there is not much use elsewhere and even on a car nowadays this is about the only part you will use it on. “No matter how hard your press this provides more pressure” 🤦 I guess this is the result of the American way of teaching math. As in, not at all. 😂

I also have a Noname one, and it never worked. I think it's broken or I'm missing something understanding how to use it.

You have to push upward to turn them.
