From Bulbapedia, the community-driven Pokémon encyclopedia.
Horn Drill (Japanese: つのドリル Horn Drill) is a Normal-type one-hit knockout move introduced in Generation I. It was TM07 in Generation I.
Horn Drill has 30% accuracy and inflicts damage equal to the target's current HP. Horn Drill will break a substitute if it hits, and can be countered for infinite damage when it does so.
Horn Drill will not affect a target whose current Speed stat is greater than the user's current Speed stat.
Generation II and on
Unlike in Generation I, Horn Drill can affect a Pokémon whose Speed stat is greater than the user's current Speed stat. However, it cannot affect a Pokémon of a higher level. The accuracy of Horn Drill depends on the level of the user and the level of the target and is worked out with the formula: Accuracy = ((level of user-level of target) + 30)%. Horn Drill ignores all changes to accuracy and evasion stats.
Horn Drill can be countered for infinite damage if it misses in Pokémon Gold, Silver, and Crystal. However, this does not apply to Pokémon Stadium 2 and later games.
