The first post implies the OP is drilling into a piece of steel affixed to the anvil, rather than drilling directly into the anvil.If going into thick cast, I'd think a smaller pilot hole would be needed though.
I think what you're describing is a drill guide or drill bushing-a hardened piece fo steel with a precision aligned and sized hole for the drill bit to pass through into the workpiece.
