Hi, Charles. I believe that you can drill into most rock with a hammer drill and carbide tipped drill made for hammer drill use. Don't plan on having your $29.95 3/8" VSR drill lasting too long in this application. You have to buy or rent a heavy duty hammer drill.
Also, the metal pieces that you put in the holes are called feathers and wedges. You might check with a stone mason to see if you can rent, buy or borrow these. You can usually find a stone mason that does this kind of work pretty close to a large cemetary. This process works about the same way the fire and ice method does, by creating a line of tension across a plane in the rock. The break then follows the line of tension from a small initial crack.
