Dynabrade 58501 Palm Air Orbital Sander 3x4.25 in

Product Description

The DYNABRADE 58501 is a palm-style air-powered orbital sander designed for finish sanding on flat and slightly contoured surfaces. It accepts a 3 x 4.25 inch rectangular sanding pad and operates at up to 10,000 OPM with a 0.09 inch (2 mm) orbit diameter, delivering a swirl-free finish on wood, composites, and painted surfaces. The tool runs on a 1/4 NPT air inlet at 90 psig and consumes 13 CFM at rated pressure. It is rated at 0.15 horsepower and includes a vacuum sanding pad (56316) for integrated dust extraction. Designed for use by finish carpenters, auto body technicians, and woodworking professionals.

This sander is suited for residential and light commercial finish work where a fine surface profile is required. The compact palm grip makes it practical for detail areas, cabinet faces, door panels, and similar flat stock. The built-in vacuum port connects to standard shop vacuum systems, keeping the work surface clear during use. The included 56316 vacuum sanding pad is the matched accessory for this tool and supports direct hook-up to dust collection equipment.

Installation Notes

Connect to a clean, dry compressed air supply regulated to 90 psig using a minimum 0.25 inch inside-diameter air hose. Always shut off and bleed the air supply before attaching or removing the sanding pad. Verify the abrasive sheet is fully seated on the pad before operation to prevent premature wear or pad damage. A licensed mechanic or experienced tradesperson should confirm the air line fittings are leak-free and rated for the operating pressure before use.
