Dynabrade 54359 Air Angle Grinder 18000 Rpm 90 Psi

Product Description

The DYNABRADE 54359 is a pneumatic angle grinder built for grinding, deburring, and surface preparation tasks in industrial and fabrication environments. Running at 18,000 RPM on a 90 psi air supply, this tool delivers consistent rotational speed through a lightweight aluminum head and composite handle. The 1/4 inch NPT rear-exhaust design directs airflow away from the work surface, reducing debris recirculation. A built-in mechanism prevents accidental start-up, supporting safer operation in busy shop or production settings. The tool ships with both a 1/4 inch and a 6mm collet insert, making it ready for a range of accessory shank sizes straight out of the package.

The 54359 is suited for metalworking, weld finishing, and precision deburring in manufacturing, aerospace, and general fabrication applications. Its compact overall length of 7.875 inches allows access in tight workspaces where larger grinders cannot reach. The composite handle reduces operator fatigue during extended use. Maintenance technicians, toolmakers, and production grinder operators are the primary installers and users of this tool. It is appropriate for both bench and in-line production environments where a consistent 90 psi regulated air supply is available.

Key Features

• 1/4 inch NPT air inlet with rear exhaust directs airflow away from the operator
• Accidental start-up prevention mechanism for safer shop handling
• Includes both 1/4 inch and 6mm collet inserts for accessory flexibility
• Composite handle construction for reduced vibration transmission and operator fatigue

Compatibility

Designed for use with grinding accessories and mounted points featuring 1/4 inch or 6mm shank diameters. Requires a regulated compressed air source capable of maintaining 90 psi and supplying up to 41 CFM at the tool inlet.

Installation Notes

This tool is installed and serviced by qualified pneumatic tool technicians or maintenance personnel familiar with compressed air systems. Before connecting or disconnecting the tool, shut off and bleed the air supply line to eliminate stored pressure. Verify that the air supply is regulated to 90 psi and that the supply line and fittings are rated for the operating pressure and flow requirements. Follow applicable OSHA and ANSI B186.1 standards for safe use of portable pneumatic tools, including proper wheel guarding and rated accessory speeds.
