Air die grinders are handheld pneumatic tools used for precision grinding, deburring, and polishing. They typically operate at high speeds, often exceeding 20,000 RPM, powered by a compressed air source at a standard pressure of 90 PSI.
Safety Mechanisms: Most units include a safety lock-out lever or throttle to prevent accidental startups.
Exhaust Systems: Rear exhaust is common to direct air and debris away from the operator and work surface.
Ergonomic Design: Features like composite housings or rubberized grips help reduce operator fatigue and provide thermal insulation against the cold air.
Adjustability: Many tools come with integrated air regulators for precise speed control during delicate tasks.
