Assuming this is a home-workshop situation and youre drilling a hole through a sheet of copper and its getting too hot - almost anything oily will work. There are several types of high-speed machine oils that are made for the purpose (heat dissipation) but many use mineral oil because it cleans up easily and is cheap. Mazola from the kitchen, sun tan lotion, etc. CAUTION: avoid overheating when using any lubricant. It can get hot enough to catch on fire. Watch your drill bit and if you see steam/vapors - STOP, give it a rest and start in again. Use a sharp drill bit and common sense. Also, depending on your situation, water works fine also.
Use a titanium bit for best results. Clamp the piece of copper to a piece of wood if possible, so that the wood supports it from underneath, and give the drill bit a place to go once it goes through the copper. Wear safety gloves and glasses to keep from being injured by small shards of metal. When you drill through it, use a fast spinning speed with the drill, but don't apply a lot of pressure, just allow the drill bit to slowly work its way through the metal.
Copper is found in mines and oil is found in oil wells.
