Is the impact function even utilized in drilling applications? I thought impact function was for driving large lag screws, for example

Great set, I've had mine for years and have only had to replace a few smaller ones (~1/8" probably). I personally use mine with the flexi-click/chameleon offset adapter, since it only accepts hex shanks. Same would go for the Milwaukee offset solution, I would think. You can also use them without any "-click" adapter in a pinch, since a hex hole drives those adapters.
Mine have a decent amount of... run-out? like if you look at them while turning (even in a standard drill chuck) they orbit the center slightly, as if they are a little bent. Could be the age of mine, but I suspect it is because they are not unibody. If you want something cheap as an EDC, these are great. Otherwise look at something unibody, if they even make hex shank bits like that. Edit: just checked and the 5/16, 3/8, and 1/2 are unibody, fwiw

The con is they are more expensive than the drill bits without ¼ shanks.
