Built for precision material removal, weld blending, deburring, and surface preparation in fabrication, aerospace, metalworking, and industrial maintenance environments, the Dotco 12L2277-36 Right Angle Grinder combines a compact right-angle configuration with a 0.6 HP motor and 12,000 RPM free speed to provide controlled performance in areas that are difficult to access with straight grinders. Its right-angle head improves working access around corners, inside assemblies, and along confined surfaces, while the rear exhaust helps direct airflow away from the workpiece for a cleaner operating area.
Part of the Dotco 12-22 Series, this grinder features a composite housing that helps reduce tool weight while maintaining durability for daily production use. The 300 Series collet accepts compatible carbide burrs and mounted wheels, allowing operators to perform deburring, edge cleanup, light grinding, and finishing tasks with excellent control. The heavy-duty low-profile head further improves accessibility when working in restricted spaces. Product specifications and features are based on the manufacturer catalog.
