The Alpha® AIR-300 Pneumatic Polisher is a compact air-powered polishing tool designed for detailed stone finishing in tight or confined areas. As a smaller counterpart to the Alpha® AIR-658, it offers controlled handling and reduced weight to support extended polishing tasks with less fatigue.
Weighing 1.6 lbs and designed for one-hand operation, the AIR-300 is suited for precision work such as sink rims, bowls, and curved surfaces. It accepts 2", 3", and 4" rubber pads, along with 3" and 4" polishing discs, and operates with a central water-feed system for consistent wet polishing.
