Train Horn Drill Attachment

Trusted Components, Real Performance

BossHorn units pair a high-output air compressor with genuine metal train horn trumpets and a custom control PCB. The control board gives three selectable volume levels, motor overheat protection, and battery deep-discharge protection. Remote wireless triggering reaches up to 2,000 feet, and compatibility spans 15+ major tool brands so you can attach the same battery you already own. Every horn is hand-assembled in the U.S. for consistent fit and finish.

Everyday Use and Practical Benefits

The train horn drill attachment snaps onto a compatible cordless tool battery for instant use. You’ll notice the metallic cone tone cuts through road noise; it’s ideal for clearing a driveway, alerting crews on a job site, or calling attention at a tailgate. No vehicle installation, no wiring—attach, trigger, and go. Portable loudness that behaves predictably and won’t surprise you with inconsistent output.
