Usually the boxes of screws come with the bottom, more silver bit. But today’s box had the duller grey, bit with a green lap band. No idea if one is better than the other or not.

Bits like that are used for impact drivers
Huh. I had no idea that one would use an impact driver on Torx screws.
I kind of mentally associate Torx with (delicate) personal electronics and associate impact drivers with big, heavy pieces of hardware with rusty bolts.
Torx is pretty standard for just about any kind of hardware nowadays. It’s actually more appropriate for construction than delicate electronics as it allows a lot more torque with less slipping. One of the benefits of a Phillips or flathead is that you’ll probably strip the screw before you over torque and break something.
I am using a cordless impact driver, which is like a cordless drill. Rather than what a lot of people imagine, an air driven impact wrench.
Vs
My impact driver accepts the same bits I would use in my cordless drill. I do have some attachments so I can use sockets and such in it for auto repairs. But I now have a cordless impact wrench I use for that more often.
