Excadrill does not learn Horn Drill. Horn Drill is a move typically associated with certain Water and Grass-type Pokémon, while Excadrill is a Ground/Steel-type Pokémon. Instead, Excadrill learns a variety of other moves through leveling up, TMs, and breeding that suit its typing and battle strategy.
Unfortunately, Nidoking doesn't learn Horn Drill at all. In order to have your Nidoking learn Horn Drill, you'll need to level up your Nidorino to level 46 (you learn Horn Drill at that level) and then evolve it into a Nidoking.
In Pokémon White 2, the moves that Excadrill is capable of learning would include ones such as Mud Sport, Scratch, Mud-slap, Rapid Spin, Metal Claw, Dig, Fury Swipes, Slash, Hone Claws, Horn Drill, Rock Slide, Earthquake Sandstorm, Swords Dance, Fissure and Drill Run.
