DYNABRADE 59019 Random Orbit Sander

The DYNABRADE 59019 is a palm-style air random orbit sander built for industrial finishing work. It runs on compressed air at 90 psi and delivers a free speed of 12,000 RPM. The 3-1/2 inch pad accepts vinyl or hook-face abrasives with a 3/16 inch orbit diameter. A rear exhaust directs airflow away from the workpiece.

Suited for single-handed finishing.

This tool suits technicians and woodworkers who need a lightweight palm sander for final surface preparation on metal, composite or wood. The 0.25 hp motor and 3/16 inch orbit are designed for fine finishing rather than aggressive material removal. Buyers who need higher power or a larger pad for rapid stock removal should look at different equipment.

12,000 RPM free speed at 90 psi

The sander reaches 12,000 RPM free speed when supplied with 90 psi compressed air through a 1/4 inch NPT inlet. It consumes 3.5 CFM average during a 15-second run and 14.0 CFM at full load, requiring a minimum 1/4 inch hose. The spindle uses a 5/16-24 thread for pad attachment.

Questions about this item

How do I connect the 1/4 in NPT air inlet and what hose size should I use?

Connect the 1/4 in NPT air inlet using a hose with at least 1/4 in internal diameter. Set the compressor regulator to 90 psi. The step people miss is checking pressure at the tool while it runs; a long or narrow hose can drop pressure below 90 psi and cut power.

When should I service the 0.25 hp motor and what parts wear first?

The rear-exhaust palm sander has no user-service schedule in the data. The 5/16 in-24 spindle bearing and the vinyl or hook-face pad wear first. Replace the pad when the hook loops no longer hold discs or the vinyl face is gouged.

How long can I run it continuously at 12,000 RPM before the 14.0 CFM demand overheats the motor?

At full load the tool draws 14.0 CFM. Most shop compressors cannot sustain that flow continuously. The practical limit is the compressor duty cycle; when the compressor cycles off, pressure drops and the sander loses speed.
