Ho to make a hole in a shelf? Answered

I need to run some cables up the back of a built in bookshelf.  How can I make a neat hole if my drill will not fit, I am trying to avoid purchasing a 90 deg Chuck?
I thought of using my small electric screwdriver but it does not have the power to drive the bit.


Can't you just dril from the other side? If not try to use the drill bit by hand.

Hi, the issue is the same. There are more than one shelf.
I will try by hand. But I think it is going to be hard going.

its possible to drill a hole with a knife point. one does not simply spin the point, but rather uses a bit more "body english" Easier to show than to explain. One could also use a drill chuck without the drill. Slightly time consuming handwork to turn a drill bit by hand. IIRC, chucks can usually be unscrewed from the drill with an allen wrench.

A little bit far out but it would also work --- Use a soldering iron to char the spot where you want the hole. You should then be able to pick the burnt wood out with a knife. It will take a while and smoke some but it would eventually get through. Be careful not to set anything on fire.

If you have a lot of time and are adventurous you can put a glob of peanut butter on the spot and then get a mouse from the pet store and put the cage over the spot where you want the hole. The vermin will chew its way through after a while.

For the fastest solution, get a grade school kid and point him at the spot. Tell him that under no circumstances is he (or she) allowed to put a hole in that spot. Withing a few hours they will have figured it all out and punched a nice clean hole for you.

I forgot I have said grade schooler at hand...

Shelving is usually pine wood and should be easily holed by a hand reamer or old hand bit or well tooled friend.

I have many well oiled friends. Not may well tooled ones :)

thank you all for your input

Try a flexible drive for your drill.

Thank you Steveastrouk. I saw one at the hardware store... but I fixated on the actual 90 degree Chuck.... :|
The only concern I might have would be on how to apply the downward pressure on the bit as those flexible drives dont seem to cater for it ...

Any thoughts on that ?

A decent one is designed for thrust loads - try it in the shop !

A good sharp bit shouldn't need a lot of force.
