Already have the right answers here. Masonry bit, or for an arrowhead, maybe a tile bit. Most arrowheads are made from obsidian, slate, or some other rock/mineral with a defined crystalline structure.
P.S. - someone suggested using water to keep the bit cool- never do that! It will temper the bit, making it brittle, which will cause it to break or dull more rapidly. Oil is waht you should use. Also, don't force the bit, allow it to do the drilling.
P.S. "but you don't have to use a hammer drill" ? I don't remember mentioning a hammer drill-in fact a hammer drill would shatter an arrowhead.

Sometimes they are called masonry bits. Some people recommend tungsten tipped bits as they are supposed to last longer, I'm yet to be convinced. But, generally the more expensive the bit the better it will be for you. You will need a hammer drill and take it slowly - no more than a minute at a time or you will burn the bit out. Buy a couple of spares just in case. Your local hardware store should be able to point you in the right direction for the bit you need.

DIAMOND DRILL BIT! If you are drilling a rock over 1" in thickness it needs to be a diamond. If you go here:

You will find an excellent guide for drilling through rock.
Good luck, Swequin

Buy a carbide drill. Some harder rock requires a diamond drill.

martin couch has the right answer but u dont have to use a hammer drill.
a regular 12V handheld will do just fine.
if you plan on drillin small quantities of arrowheads im pretty sure you dont have to cool it off with oil and such.
hes right about water making it brittle but if you dont plan on using the bit extensively then it really doesnt matter.
carbide or tungsten is the norm.
i usually buy the $40 ones.
i hope this helped

Maybe a " Masonry Bit" but remember to keep dipping in water often to keep it cool when drilling through rock surfaces.

Cabide bits, use oil to cool as needed, regular drill should work, hammer drill on H.D. job. Depending on stone, even carbide won't last all that long, take it easy and steady.

Get a masonry bit.
It's designed to drill through concrete, cinder blocks, etc.

Hardware store. Get the person which is best. Usually carbide, but you need to let it cool, or buy more than one.
