Once the location of the hole is determined, use a punch, or a nail will do, and tap an indentation at that spot. This will prevent your drill bit from sliding.
Then use a regular metal bit, of a size slightly smaller than the screw.
Be sure to use metal screws and not wood screws.

There's probably a better way to mount the air conditioner than having to attach it to the window frame. You really should avoid doing anything to the window in my opinion. A handyman would have a lot of other solutions to mounting the air conditioner.

Use a smaller bit hss first to make a pilot hole, take it easy will snap else. Then use the right sized hole. Would be better to tap a thread and then screw a screw in. Use a bit of cutting compound if necessary.

A self tapping screw is probably your best bet. Use a screw bit in your drill and place the screw where you want. I usually pull the trigger lightly till the screw starts to bite then pull the trigger fully till the screw sets.

you can always go buy "self tapping screws". They create the hole as they are screwed in. Might wanna use a drill and screw attachment to get them in there.

you'll have to use the proper bit - in this case a metal bit. Use a high torque low-speed setting so you have better control of the depth for the punch. once you punch through, use a high speed low torque setting, and gently run the bit back and forth in the hole a couple of times to smooth out and remove any flash (sharp bits).

Use a drill bit meant for use with metal in an electric drill.
