We've refined the build, improved the trumpet tuning, and kept everything you already love — real train horn sound from a one-handed, battery-powered device that's ready to blast the second you snap in your M18 battery.
This isn't a cheap air horn or a plastic toy. It's a handcrafted drill train horn built using a Milwaukee® Impact Driver body as the housing, fitted with dual metal trumpets and a high-output compressor. Compact, loud, and dead simple to use.
