Not a drill pro?
Drilling a straight hole with your drill without the bit going all over the place is not so easy for a DIY novice.
Then this trick is for you.
With the help of an old CD, you will be able to drill straight holes as cleanly as a DIY master.
1. Get an old CD.
2. Place the CD hole exactly where you want to drill a hole.
3. Place the drill bit in the center of the CD hole.
4. Turn on the drill.
Voila, you have drilled a perfectly straight hole with your drill :-)
