impact drivers aren't ideal for drilling but if you really want to go through with it you need a set of 1/4" hex shank drill bits like this
An alternative is getting a proper drill bit chuck that fits into you impact driver so that you can use any bits you want (give you the option to get bits specific to the material you're drilling)
But really the best thing to have is a real drill meant for drilling, especially the larger the hole you're trying to drill.
EDIT: the reason impacts aren't ideal for drilling is that by nature they're supposed to start banging away in small powerful knocks when they encounter resistance, and which allows a relatively small motor to drive deep screws or loosen tight bolts, but a drill bit cuts most efficiently when it just powers through and keeps spinning and slicing. If the bit stops and start chipping you're mangling the work and might get your bit jammed. Newer more expensive drills have some power management built in to adjust torque automatically depending on load to try and keep the bit spinning smoothly, which is even better, but even a cheap drill will be better at drilling holes than an impact drive.
That said, for what you're doing, the impact drive will do exactly what you want (for free). So have at it. But if you want to start drilling large holes in those joists, get a drill.
