An air angle grinder (or pneumatic angle grinder) is a heavy-duty tool driven by compressed air rather than an electric motor. It features a rotating abrasive or cut-off disc set at a right angle to the body, and is primarily used for cutting metal, grinding welds, and removing rust. [1, 2, 3]
Designed for robust performance, this tool offers several specific operating characteristics and benefits:
Power Source: It connects to an air compressor (typically requiring 90 psi of operating pressure) using standard airline fittings. [1, 2, 3]
High RPM: These grinders operate at high rotational speeds, commonly ranging from 10,000 RPM to 20,000 RPM, to quickly strip material and make clean cuts. [1, 2, 3, 4, 5]
