Dotco 12L2718-28 Air Angle Grinder 4 Inch 18000 Rpm

Product Description

The DOTCO 12L2718-28 is a pneumatic angle grinder designed for grinding, deburring, and surface preparation tasks in industrial and trade environments. It accepts a 4-inch Type 1 wheel and runs at 18,000 RPM, driven by a 90 psi shop air supply through a 1/4-inch NPT inlet. The rear exhaust configuration directs airflow away from the work surface and operator. Weighing 3.2 pounds and measuring 8 inches in overall length, the 12L2718-28 features a low-profile angle head and ergonomic composite housing that reduces fatigue during extended use. This tool is installed and operated by machinists, fabricators, pipefitters, and maintenance mechanics who rely on consistent pneumatic tooling.

The 12L2718-28 is suited for metal fabrication shops, maintenance facilities, and industrial job sites where a compact, lightweight angle grinder is needed for tight-access grinding and finishing work. The low-profile head geometry allows access to recessed welds, pipe joints, and confined workpiece surfaces. The composite housing keeps weight low without sacrificing grip. It is compatible with standard 4-inch Type 1 abrasive wheels commonly found in trade supply.

Key Features

• Rear exhaust keeps debris and airflow directed away from the operator and work surface
• Low-profile angle head provides access to confined grinding locations
• Ergonomic composite housing reduces tool weight and operator fatigue
• Compact 8-inch overall length suits tight working envelopes

Compatibility

Designed to accept 4-inch Type 1 abrasive wheels and connect to standard 1/4-inch NPT pneumatic supply lines at 90 psi operating pressure.

Installation Notes

Installation and operation of pneumatic angle grinders should be performed by qualified personnel following OSHA and ANSI B11 abrasive wheel safety standards. Disconnect the air supply before mounting or changing wheels, and verify the wheel is rated at or above the tool free speed of 18,000 RPM. Inspect the wheel for cracks or damage before each use and ensure the guard is properly secured. Regulate shop air to the recommended 90 psi operating pressure for safe and consistent performance.
