The Alpha® AIR-300 Pneumatic Polisher is a compact air-powered polishing tool designed for detailed work in tight, hard-to-reach areas. Built as a smaller counterpart to the Alpha AIR-658, it offers precise control for applications such as sink rims, bowls, and edge detailing where larger polishers are difficult to maneuver.
Weighing only 1.6 pounds, the AIR-300 is ergonomically shaped to reduce hand fatigue during extended polishing sessions. Its lightweight design, combined with pneumatic power and a central water-feed system, supports consistent polishing performance in both shop and jobsite environments.
Key Features
- Compact Pneumatic Polisher: Designed for precision polishing in confined areas where standard polishers cannot reach.
