Dynabrade 58504 Palm Air Orbital Sander 3.25x5 in 10000 Opm

Product Description

The DYNABRADE 58504 is a palm-style air-powered orbital sander built for surface preparation work in finishing, woodworking, auto body, and light industrial applications. It operates at 10,000 orbits per minute (OPM) and uses a 3.25 x 5 inch rectangular pad, making it well suited for flat panel sanding and tight finish work. The tool connects via a 1/4 NPT inlet and requires a supply pressure of 90 psi with an air consumption of 13 CFM. Weighing 2.7 pounds, it is compact enough for extended single-hand use without excessive fatigue. Installation and operation are handled by experienced finishing technicians, body shop technicians, and skilled tradespeople working with pneumatic tooling.

The 58504 is used in residential cabinet shops, automotive body finishing, furniture manufacturing, and commercial millwork environments. Its rectangular pad geometry allows consistent contact on flat surfaces and edges where round random-orbit sanders lose coverage. The 1/4 NPT inlet is compatible with standard shop air quick-connect fittings. Adequate air volume from the compressor is important for maintaining consistent OPM output during sustained use; a compressor capable of delivering at least 13 CFM at 90 psi is recommended for continuous operation.

Key Features

• 10,000 OPM operating speed for efficient material removal and fine finishing
• 3.25 x 5 inch rectangular pad provides full coverage on flat panels and broad surfaces
• 1/4 NPT air inlet compatible with standard pneumatic shop fittings
• Operates at 90 psi supply pressure with 13 CFM air consumption
• Compact palm grip design at 2.7 pounds reduces operator fatigue during extended use

Compatibility

Designed for use with standard hook-and-loop or PSA abrasive sheets cut or sized to fit a 3.25 x 5 inch rectangular pad; verify abrasive sheet format before ordering.

Installation Notes

Connection and disconnection should always be performed with the air supply line depressurized. Verify that the supply line and fittings are rated for the required 90 psi operating pressure before connecting the tool. Confirm the air compressor output meets or exceeds 13 CFM at 90 psi to avoid speed loss under load. Always wear appropriate respiratory protection and eye protection when operating pneumatic sanders.
