Dynabrade 56853 Palm Air Random Orbital Sander 5 Inch

Product Description

The DYNABRADE 56853 is a pneumatic palm-style random orbital sander designed for surface finishing, prep work, and material removal in professional shop and field environments. Powered by compressed air at 90 psig through a 1/4 NPT inlet, it delivers 12,000 orbits per minute with a 3/32-inch orbit diameter and 0.28 HP output. Air consumption is rated at 18 CFM, so a properly sized compressor and supply line are required for consistent performance. The tool accepts a 5-inch round sanding backing pad and ships with a premium urethane weight-mated sanding pad included. A built-in vacuum port supports dust extraction for cleaner work surfaces.

The 56853 is suited for automotive body finishing, woodworking, and general metal or composite surface preparation. Its palm grip format makes it practical for flat panel work, door skins, tabletops, and similar applications where a low-profile, hand-controlled tool is preferred. The random orbital action reduces swirl marks compared to straight-line or single-motion sanders. This tool is used by automotive refinishers, body shop technicians, millwork professionals, and industrial maintenance crews who need consistent finishes with pneumatic tooling.

Installation Notes

Installation and operation should be performed by personnel familiar with pneumatic tooling and compressed air systems. Before connecting or disconnecting the air supply, shut off the compressor valve and bleed line pressure. Verify that supply air is clean, dry, and regulated to the rated operating pressure before use. Follow applicable workplace safety standards and tool manufacturer guidelines for abrasive product selection and guard requirements.
