Looking for drill bit size?

[RussianGiraffe13]

im wiring my room for ethernet as wifi is just way slower. Im looking for a drill bit that can go through both wood and stone wall. Im assuming a 12inch bit will be needed? and if 12inch is overkill, just to be safe..... also a 1inch diameter. Budget $25 for a drill bit

This is a strange post. Look on line at what's on offer from your nearest hardware shop.

For a 1" diam and 12in long drill bit, it'll probably have to be SDS max masonry drill. You'll need a SDS max drill for it though.

You don't use "a" drill bit for stone and wood.
You use a regular bit for the wood, and a masonry bit for the stone. Assuming, of course, you have a hammer drill to go through the stone.

1" dia hole through stone needs a really good hammer drill. I have one. Do you? And probably more than one bit. 0.5" to start, then the 1".

How are you currently getting power into the room? Might just be better to install wall plates with an Ethernet jack.

Need more info to give a good answer.
Type of stone? thickness of stone?
If thin veneer sandstone you can get by with a cheap bit and drill.
If 6-8 inch thick granite you will definitely need a SDS hammer drill and bit.
If the cable you are running has the ends already attached you can get by with a 5/8 inch bit for one cable in the hole.
If it does not have ends already attached 1/4 inch bit will work for one cable.

There are potentially other solutions rather than drilling holes in the wall.
Powerline devices, for one.
