Built for versatile finishing, deburring, light grinding, and surface preparation in confined work areas, the Dotco 12LF280-32 Right Angle Grinder/Sander combines a compact right-angle design with a 12,000 RPM free speed to provide smooth, controlled material removal using compatible 1/4-inch shank accessories. Its 1/4" collet accommodates a variety of carbide burrs, mounted points, and shank-mounted sanding accessories, allowing a single tool to handle multiple finishing tasks. The lightweight composite housing helps reduce operator fatigue, while the rear exhaust directs discharged air away from the work area for improved comfort during extended operation.
The Dotco 12-12 Series is well suited for production environments where access, precision, and operator control are essential. The right-angle head reaches into corners, around fixtures, and inside fabricated assemblies that are difficult to access with straight tools, making this model an excellent choice for aerospace manufacturing, metal fabrication, industrial maintenance, and precision finishing applications.
