Dynabrade 57900 Right Angle Air Orbital Sander 15000 Opm

Product Description

The DYNABRADE 57900 is a right angle air orbital sander designed for precision surface finishing in professional trade and industrial environments. Powered by compressed air at 90 psi and consuming 20 CFM, it operates at 15,000 orbits per minute with a 0.03125 inch (1 mm) orbit diameter. The 0.12 HP motor delivers consistent power through a 1/4 NPT inlet connection. The tool ships with a 94407 Flow-Control Dynaswivel, a triangular hook-face pad, and a tear-drop hook-face pad, making it ready for detail sanding in tight or contoured areas. Automotive, aerospace, woodworking, and fabrication professionals are the primary users of this tool.

The 57900 is suited for right angle access applications where a standard inline sander cannot reach. The triangular and tear-drop pad geometry makes it effective for sanding into corners, edges, and curved surfaces on panels, cabinetry, composites, and metal fabrication work. The flow-control Dynaswivel allows the air hose to rotate freely and reduces hose drag during extended use. A minimum 0.25 inch hose size is required to deliver adequate airflow to the motor.

Key Features

• 15,000 OPM operating speed for fast, consistent material removal and finishing
• 1 mm (0.03125 inch) orbit diameter for fine finish work with reduced swirl
• Right angle head design for access in confined or contoured areas
• Includes 94407 Flow-Control Dynaswivel to reduce hose torque and drag
• Ships with both triangular and tear-drop hook-face sanding pads
• 1/4 NPT inlet compatible with standard shop air supply systems

Compatibility

Designed as an OEM-style pneumatic orbital sander compatible with standard hook-face abrasive sheets in triangular and tear-drop pad formats. Requires a compressed air supply delivering 90 psi and 20 CFM through a minimum 0.25 inch diameter hose.

Installation Notes

Installation and operation should be performed by qualified personnel familiar with pneumatic tool safety. Before connecting or disconnecting the tool, shut off and bleed the air supply line. Verify the shop air system can sustain 90 psi and 20 CFM at the tool inlet under load to avoid performance loss. Consult applicable OSHA and ANSI B186.1 standards for safe use of portable air tools in the workplace.
