I need to drill a hole in a shelf that's half an inch deep but I don't want to drill a hole through the shelf. What's the best way of doing that? I have a drill and i was thinking of showing just a half an inch of the drip bit. This way, I can force the drill to drill all the way to the end of the drill bit and not go through the shelf. However, a part of the drill bit's thread is being held by the drill for grip. Would using the drill and the drill bit in this way cause damage?

Yes, the drill chuck will mar the finish of the shelf. There is a slight chance of damage to the chuck. Plus, choking down on the bit, like that, obscures your view of the hole (the drill and chuck block it) -- making precision harder to accomplish.
The correct way to do this is to use a drill stop.

Drill stops are less likely to slip than tape or zip-ties, and are much better for precise and/or repeated drilling.
If marring the finish is an issue, clamp a piece of 1/8th plywood over the site and adjust the drill stop accordingly.
PS: A piece of wood over the hole is usually a good idea anyway, when drilling finished surfaces. It helps reduce both splintering and the scratching that occurs when flakes of drilled wood or metal whip around the bore site.
