Horn Attachment for Drills

Performance & Engineering You Can Rely On

BossHorn’s drill horn attachment pairs a high-output air compressor with metal train horn trumpets and our custom control PCB. You get three selectable volume levels, motor overheat protection, and battery deep-discharge protection—plus wireless triggering up to 2,000 feet. Hand-assembled in the U.S., the unit accepts batteries from 15+ major tool brands and delivers professional-grade sound without vehicle installation or wiring.

Portable Convenience Built Around Real Tools

The drill horn attachment is ready out of the box—snap on a compatible cordless battery and you’re set. The compact compressor breathes through machined fittings; metal trumpets produce a clear, penetrating tone you can hear over road and wind. Great for roadside emergency signaling or yard-wide attention getting, it’s easy to move between vehicles or job sites and stores cleanly when not in use.
