Dynabrade 56859 6 Inch Palm Air Random Orbital Sander

Product Description

The DYNABRADE 56859 is a 6-inch palm-style air-powered random orbital sander built for professional surface finishing applications. It operates at 12,000 orbits per minute (OPM) with a 3/32-inch orbit diameter, delivering consistent, swirl-minimized material removal on flat and contoured surfaces. The tool runs on a 90 psig air supply through a 1/4-inch NPT inlet and consumes 18 CFM at full load. Output is rated at 0.28 horsepower. It ships with a premium urethane weight-mated sanding pad matched to the tool's balance profile. This sander is installed and serviced by professional finishers, auto body technicians, and industrial fabricators.

The 56859 is suited for residential and commercial finishing work where a palm-grip random orbital tool is appropriate. Typical applications include wood surface prep, automotive body finishing, composite panel work, and general production sanding where a 6-inch disc is the standard. The round pad configuration and random orbital action help reduce visible scratch patterns left by straight-line or rotary tools. A minimum hose size of 0.25 inches is required to maintain adequate airflow and tool performance under sustained use.

Key Features

• 6-inch round pad with 3/32-inch orbit diameter for refined surface finishing
• 12,000 OPM operating speed for efficient, consistent stock removal
• 90 psig inlet pressure via 1/4-inch NPT connection
• 18 CFM air consumption — size compressor and supply lines accordingly
• Includes premium urethane weight-mated sanding pad for balanced operation
• Compact palm-grip body at 0.3 pounds for reduced operator fatigue during extended use

Compatibility

Designed as an OEM-style pneumatic palm sander accepting standard 6-inch round sanding discs compatible with hook-and-loop or pressure-sensitive adhesive (PSA) backing pads of the appropriate type.

Installation Notes

Installation and operation should be performed by personnel familiar with pneumatic tool safety practices. Shut off and bleed the air supply before connecting or disconnecting the tool from the air line. Verify that the compressor and supply line can sustain 90 psig and a minimum 18 CFM flow rate with at least a 0.25-inch inside-diameter hose to prevent pressure drop under load. Inspect the sanding pad and disc attachment before each use and replace worn or damaged pads immediately.
