Industrial Air Disc Sander

The Dynabrade 48500 is a 0.4 hp pneumatic disc sander built for heavy-duty industrial use. Its fixed-speed motor drives a 2 in pad at 25,000 RPM for rapid material removal. The offset grip design improves control during extended sanding sessions. It connects to a compressed air supply via a 1/4 in NPT inlet.

Capacity and Headroom

The tool delivers consistent performance at 90 psi with an air consumption of 23 cfm. The 2 in pad diameter is fixed, limiting the working surface to small areas and spot repairs. Maximum disc speed is locked at 25,000 RPM with no variable adjustment. It lacks an integrated dust collection system, requiring external extraction for clean operation.

Build Integration

Operation requires a compressor capable of sustaining 23 cfm at 90 psi through a minimum 1/4 in hose. The 1/4 in -20 spindle thread accepts compatible locking-type abrasive discs. The non-vacuum design frees up hose routing but adds dust management to the workflow. Offset grip geometry suits vertical and overhead surfaces where inline tools struggle.

Questions about this item

Will the 1/4 in. NPT air inlet and 23 cfm consumption work with my existing 1/4 in. hose and shop compressor?

Yes, the tool uses a 1/4 in. NPT inlet and requires a minimum 1/4 in. hose; your compressor must supply 90 psi and at least 23 cfm to run the sander at full speed.

How can I confirm the sander is reaching its rated 25,000 RPM after hooking it up?

With 90 psi at the inlet and a 2 in. disc fitted, the motor runs at a fixed 25,000 RPM; listen for steady high-pitched tone and feel smooth, vibration-free cutting on the workpiece.

Does the box include any abrasive discs or a backing pad, or must I buy them separately?

The sander comes with the 2 in. locking-type backing pad installed; abrasive discs are not included and must be purchased separately.
