Are impact drill bits better than non-impact?
Is the impact function even utilized in drilling applications? I thought impact function was for driving large lag screws, for example

I'm honestly not sure, other than the ability to drive them with an impact driver. There can be a few cases for this off the top of my head, but all revolve around that-- if you only have your driver, or your driver is shorter than your drill and you need to utilize that.

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

I've debated buying these every time, but I never considered needing in the flexi-click offset. Instantly made me buy it finally 🤣

I have one set and the smaller size ones are easy to break. Maybe i should get a softer non impact set instead.

Sometimes you need to drill farther. These can go into a bit holder instead having to get a special long one. If you run into this enough you probably just buy the longer one but the hex ending can have a few more uses.

I've switched over to impact bits, and find it a MAJOR hassle to go back to chuck based alternatives,the power and ease of swap does it for me

Prefer these types of drill bits. I use them at work often. Though not ideal, in a pinch, I use it in an impact driver. Otherwise I use them in my drill driver. The utility to able to use it in either is useful.

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