For a bit of drill action, combine a Stone with a Needle. Press and hold B to charge, and release B to launch the power tool.”
— Description • Nintendo Power
Drill is a powerful combination ability that Kirby can utilize by mixing Stone with Needle in Kirby 64: The Crystal Shards. When activated, a drill grows from Kirby's arm which allows him to rocket sideways, massacring all enemies in his path. By releasing the B button, Kirby releases the drill and it continues on, plowing through enemies until it disappears. It can go through walls as well.
Kirby fires a drill off his hand that spirals forward until it goes off screen.
Kirby's drill drags him forward through enemies. Once the B button is released the Launch attack is performed.
Down + B (In midair)
Kirby stands on his drill as it flies towards the ground. Once he hits the ground he will continue acting like he is drilling until B is released. If the player releases B in midair, the drill will fire off downward.
Kirby shoots a drill to the left or right, which he can either let go of or hold onto.”
