Built for precision deburring, edge blending, and light material removal in metal fabrication, aerospace, maintenance, and production environments, the Dotco 12L1302-36 Gearless Right Angle Grinder combines a compact right-angle configuration with a 0.3 HP air motor and a 20,000 RPM free speed for controlled performance in confined work areas. Its 1/4" collet accepts common carbide burrs and mounted points, while the gearless direct-drive design helps deliver smooth power transfer with fewer moving parts. The front exhaust directs airflow away from the work area, helping maintain visibility during finishing and deburring operations.
The lightweight composite housing helps reduce tool weight while providing a comfortable grip for extended use. Suitable for finishing welds, removing burrs, cleaning castings, and preparing surfaces, this grinder is rated for operation at 90 PSI (620 kPa) using the manufacturer's recommended air supply.
