The industrial- and standard-duty Dotco inline air grinders are ideal for smoothing weld joints and deburring finished parts, as well as for die and mold operations. These variable-speed straight grinders incorporate a high-speed motor (up to 34000 rpm) to meet high-material removal demands and perfectly balanced parts for reducing vibrations and maintaining tool stability. They can be either used with 1.2-inch carbide burs for deburring hard materials such as stones, steel, hardwood and ceramics, or 1-inch-mounted grinding wheels for general cutting, shaping and grinding applications. These compact grinders require a maximum air pressure of 90 psi to operate and are available in front and rear exhaust configurations.
