While official and in-game sources refer to the item as originating from the Super Smash Bros. universe, its appearance is nearly identical to the Drill Arm from Kid Icarus: Uprising and behavior is nearly identical to the Stone-Needle combination from Kirby 64: The Crystal Shards, also called the Power Drill. Similarly to the item, the Drill Arm's charged shot fires a drill that plows through enemies, dealing ongoing damage for a time. Unlike the Drill Arm, however, the item has a much shorter base, no homing ability, and can only be fired once.
This item is composed of two parts: a yellow base, and a detachable drill head. The drill can only be thrown horizontally; when fired, the drill advances in a line dealing multiple hits, allowing it to easily break shields or, upon a successful hit, drag the enemy along in the direction it is fired. The projectile is very hard to DI out of, causing a trapped victim to either be dragged off of the stage for a KO or be pinned against a wall and hit continuously until the drill explodes. After firing the drill, the base remains in the user's hand: it can then be thrown for a surprisingly large amount of knockback, similar to a hammer head. Both the drill and the thrown base can be reflected or perfect shielded to nullify it. If fired into a wall, the drill will linger on the wall for several seconds before exploding. Said explosion will do high damage to any player nearby, including the one who originally fired it.
