How can i crack open this ground safe

I have a ground safe left from my great grandmother and i dont know whats inside it. We inherited the house and just found out about it. I was suggested to drill a whole into it and insert a snake camera instead of spending lots of energy on trying to crack it open just for the end to be empty. i need a bit of expertise before proceeding to drill. What kind of drill bit would i need to drill such a safe? And also, are there tiny tiny snake cameras out there? I looked up online but most of them are a bit thick, are there ones that are too thin to go into a hole? (The safe has a dial knob but its broken and we threw it away, it goes in the center, i included the image)
