Ceramic Flower Pots How Do I Punch A Drainage Hole In Ceramic Flower Pots?

How do I punch a drainage hole in ceramic flower pots? - ceramic flower pots

I bought a couple of ceramic pots at the dollar store and have no drainage holes, surprise, surprise! I've tried a hole with a masonry drill bit and got nothing. My father said ceramic is very hard and I am the shadow of the small or destruction of the motor with the drill and told me a hole chizel try. May this work or is it another way?
