Dynabrade 58502 Palm Air Orbital Sander 3x4-1/4 in

Product Description

The DYNABRADE 58502 is a palm-style air-powered orbital sander built for professional finishing work on flat and slightly contoured surfaces. It accepts a 3 x 4-1/4 inch rectangular sanding pad and operates at up to 10,000 OPM, making it effective for stock removal and fine finishing on wood, metal, and composites. Air supply requirements are 13 CFM at 90 psig through a 1/4 NPT inlet. The unit weighs 2.6 pounds, keeping fatigue manageable during extended use. It ships with the 56316 vacuum sanding pad and includes an integrated vacuum port for dust collection at the source. HVAC sheet metal fabricators, finish carpenters, auto body technicians, and industrial maintenance crews are the primary installers and users.

The 58502 is suited for flat-panel sanding tasks in both residential and light commercial environments. It performs well on drywall feathering, wood surface prep, and metal finishing where a rectangular pad provides better edge coverage than a round disc. The 3 inch pad width and 0.09375 inch orbit diameter (2 mm) deliver a controlled, swirl-minimizing scratch pattern appropriate for final-stage finishing passes. The built-in vacuum compatibility makes it practical in enclosed work areas or finished spaces where dust containment is required.

Designed for use with standard 3 x 4-1/4 inch rectangular sanding pads and compatible vacuum sanding accessories. Ships with the 56316 vacuum sanding pad. Requires a minimum 1/4 inch hose and an air supply capable of delivering 13 CFM at 90 psig.

Installation Notes

Installation and operation should be performed by a qualified user familiar with pneumatic tool safety. Ensure the air supply is depressurized and the hose disconnected before changing pads or attachments. Verify the air line delivers clean, dry, lubricated air at the specified pressure and flow rate to prevent premature motor wear. Follow all applicable workplace safety and ventilation requirements when sanding in confined spaces.
