Right-Angle Air Disc Sander 0.33 HP

This pneumatic disc sander delivers 0.33 horsepower at a fixed 18,000 RPM for material removal and surface preparation. The right-angle grip provides control in confined work areas where inline tools cannot reach. It is suited for metal fabrication, automotive body shops and general industrial finishing tasks that demand consistent speed.

Locking Abrasive Mount and Fixed Speed

The locking abrasive mount secures 2-inch discs without tools, reducing changeover time between grits. Fixed-speed operation eliminates variable-speed drift, giving repeatable results on blended edges and weld seams. The non-vacuum design means dust extraction must be managed separately in the workshop.

20 CFM Air Consumption at 90 PSI

The tool requires a continuous 20 cfm supply at 90 psi through a 1/4-inch NPT inlet, so the compressor and hose must sustain that flow without pressure drop. A minimum 1/4-inch hose internal diameter is specified; smaller bore lines will starve the motor and cut power. The 3/8-inch-24 spindle thread limits disc choice to that pattern.

Questions about this item

How often will the 2 in locking abrasive pad need replacing on the 52590?

The 2 in locking pad wears with use; replace it when the abrasive surface no longer cuts cleanly or the backing shows damage.

What stops the 0.33 hp motor from running continuously at 18,000 RPM?

The tool needs a steady 90 psi supply at 20 cfm; if the compressor cannot maintain that flow, speed will drop first.

How much noise and heat does the 52590 produce during all-day sanding?

Expect typical air-tool noise levels and warm exhaust air; the right-angle body stays manageable with a 1/4 in hose feeding 90 psi.
