Drill Crusher

"Ready, go! Vortex Break!"

- Finisher Announcement

The Rotary SwordGun Drill Crusher (ロータリー剣銃ドリルクラッシャー) is Kamen Rider Build's primary weapon. It can be accessed by any form using either the Rabbit or Tank Fullbottles, and can also be wielded by Sento and Ryuga while not transformed without any problem.

Modes
The Drill Crusher is able to change from its base Blade Mode (ブレードモード) into its Gun Mode (ガンモード) by removing the drill and inserting the tip into the side of the handle, allowing Build to switch from close quarter combat to ranged combat.

Finishers
The Drill Crusher's finisher is the Vortex Break (ボルテックブレイク). To activate it, Build must plug a Fullbottle into the opposing flat side of the weapon.
 * Blade: Build channels the energy of a Fullbottle and performs a powerful slash.
 * Rabbit: Build performs a red energy slash.
 * Kaizoku: The blade on the Drill Crusher spins such that it creates an energy whirlpool before Build slashes the enemy twice with it.
 * Gun: Build channels the energy of a Fullbottle and performs a powerful blast.
 * Harinezumi: Build shoots white energy spikes at the enemy.
