  • TypeSanders
  • Smooth finish from 3/16 in random orbital motion

  • Variable speed control for different applications
  • Comfortable two-handed grip reduces operator fatigue
  • Lightweight 2.5 lb design improves manoeuvrability

Air random orbital sander, 0.5 hp

This air-powered random orbital sander delivers 0.5 horsepower through a gearless motor. A 3/16-inch orbit diameter and 23 cfm air consumption at 90 psi give consistent material removal. The extended grip and 11 3/8-inch length provide two-hand control for heavy-duty surface preparation.

Professional finishing and prep work

Technicians who need a non-vacuum orbital sander for adhesive-backed discs on large panels will find the variable speed and rear exhaust suited to long sessions. Shops without a 3/8-inch minimum air hose or a 1/4-inch NPT supply should look at electric alternatives instead.

0.5 hp gearless motor at 90 psi

The gearless motor produces 0.5 hp when supplied with 90 psi through a 1/4-inch NPT inlet. This single power figure determines whether the tool matches the compressor capacity available in the workshop.

Questions about this item

Does the Dynabrade 58405 sander come with abrasive discs or an air hose, or must I buy them separately?

The tool itself is supplied; adhesive-backed abrasive discs and a 3/8 in minimum air hose with 1/4 in NPT fitting are not included and must be purchased separately.

The specs list both 0.45 hp and 0.5 hp — which figure should I use when sizing my compressor?

Use the 0.5 hp rating for compressor sizing; the tool consumes 23 cfm at 90 psi, so the compressor must deliver that flow continuously.

What does the 3/16 in orbit diameter mean for material removal on a real job?

The 3/16 in random orbit gives aggressive stock removal while still leaving a swirl-free finish, suited to heavy-duty sanding on metal, composite or wood.
