Dynabrade 57810 Palm Air Orbital Sander 3-2/3x7 in

Product Description

The DYNABRADE 57810 is a palm-style pneumatic orbital sander designed for finish sanding operations on flat and mildly contoured surfaces. It accepts a 3-2/3 x 7 inch rectangular sanding pad and runs at 10,000 orbits per minute (OPM) with an orbit diameter of 0.09375 inches (2 mm), producing a fine, swirl-minimized finish. Air consumption is 16 CFM at a rated 90 psi inlet pressure through a 1/4 NPT air inlet. At 0.28 horsepower and 3.1 pounds, the tool balances output with manageable weight during extended use. Includes the 57850 vinyl-face sanding pad. This tool is installed and serviced by finishing professionals, automotive body technicians, and skilled woodworkers.

The 57810 is suited for surface preparation, sealer leveling, and fine finish sanding in residential cabinetry shops, automotive refinishing, and light industrial finishing environments. The rectangular pad format is well matched to flat panel work, door faces, and tabletops where orbital motion needs to cover broad, even areas efficiently. A minimum hose size of 0.25 inches is required to maintain adequate airflow. No vacuum port is included, so dust collection requires an external shroud or ambient extraction.

Installation Notes

Installation is performed by finishing technicians or qualified pneumatic tool users. Before connecting or disconnecting the tool, depressurize the air line and confirm the supply regulator is set to 90 psi. Use a properly rated 0.25 inch minimum inside-diameter air hose to avoid pressure drop that can reduce tool performance. Always inspect the sanding pad and abrasive attachment before operation to ensure secure seating.
