Forstner bits are the best way to get a clean hole in wood. Harbor Freight has a 1/4" to 1" set for about $10 and a set that goes to 2 1/8" for $40.
For best results drill until the pilot tip comes out the other side. Then turn the work over and finish drilling from the back. This prevents splintering on the backside.
Be careful using spade bits of 1 inch or so on fragile box lids, one slip could tear it apart, better to mark around the size of the hole, drill a small hole inside and use a fret saw with a thin multi-angled blade to cut out the hole, makes a neater job! (-:

Those 7/8 inch ones just press in, really easy.

I use these from Gitty, I was thinking they were 1 inch but they are actually 7/8. My mistake. You can see them on quite a few of my builds.

I use the 1 inch grommets from Gitty, and cut a 7/8 inch hole with a forstner bit, they press in real nice and tight.
