DYNABRADE 56853 Air Orbital Sander 5 in Palm

SKU CH-3GKJ-69V59

A 5-inch pneumatic orbital sander with a 3/32 in orbit, 0.3 hp motor and 2.1 lb palm grip for variable-speed finishing

  • 5 in random orbital motion produces swirl-free finishes
  • Gearless 0.3 hp motor delivers consistent power with less maintenance
  • Variable speed control matches abrasive to material
  • Self-vacuum design captures dust at the source
  • Lightweight 2.1 lb palm grip reduces operator fatigue

5-inch palm orbital sander for finishing

The Dynorbital Supreme 56853 is a pneumatic random-orbital sander built for heavy-duty finishing on wood, metal or composite surfaces. Its 5-inch disc diameter and palm grip suit technicians who need controlled material removal in tight work areas. The gearless motor reduces vibration during extended use.

Self-vacuum system with rear exhaust

A built-in self-vacuum captures dust at the pad while the rear exhaust directs airflow away from the workpiece. Variable speed control lets the operator match 0.3 hp output to the material without changing air pressure. The tool draws 18 cfm at 90 psi through a 1/4-inch NPT inlet.

Pressure-sensitive adhesive pad included

The PSA abrasive mount accepts standard 5-inch sticky-back discs for quick changes without tools. A 1/4-inch minimum hose size maintains flow to the gearless motor. The 8 1/2-inch length and 2.1 lb weight keep the sander balanced for vertical and overhead sanding tasks.

Questions about this item

How do I hook up the 1/4 in NPT air inlet and what hose size is required?

Connect a 1/4 in NPT fitting to the rear inlet and run at least a 1/4 in ID hose; the tool needs 90 psi and draws 18 cfm so an undersized line starves the motor.

When will the PSA backing pad need replacing on this Dynorbital Supreme?

The pressure-sensitive adhesive pad wears with heavy use; swap it when discs no longer stick flat or the 3/32 in orbit leaves swirl marks.

At what point does the 0.3 hp motor hit its limit during continuous sanding?

Sustained load at 18 cfm and 90 psi is the ceiling; if pressure drops below 90 psi the random orbital action slows and material removal falls off.
