  • 3-inch locking pad secures discs without tools

Industrial Right-Angle Disc Sander

The DYNABRADE 48531 is a pneumatic disc sander built for heavy-duty material removal. Its right-angle grip places the 3-inch pad perpendicular to the operator for access inside corners and on vertical surfaces. A 0.4 hp motor drives the spindle at a fixed 15,000 rpm through a 1/4 in.-20 thread. The tool requires a 90 psi supply delivering 21 cfm through a 1/4 in. NPT inlet.

Metal Fabrication and Weld Prep

This sander suits technicians cleaning welds, removing coatings or blending edges on steel and aluminium where a fixed high speed is acceptable. The locking abrasive mount secures 3-inch discs without a separate nut. Shops without a compressor capable of 21 cfm at 90 psi should consider electric alternatives. Operators needing variable speed for heat-sensitive plastics or fine finishing will require a different tool.

21 cfm Air Consumption at 90 psi

The compressor must sustain 21 cfm at 90 psi or the sander will lose speed under load. A 1/4 in. minimum hose bore and matching NPT fittings are needed to deliver that flow without excessive pressure drop. Verify your air system meets this demand before purchase.

Questions about this item

What limits continuous runtime on the 0.4 hp motor?

The 0.4 hp motor draws 21 cfm at 90 psi; if the compressor cannot sustain that flow, pressure drops and the sander stalls.

How much noise and heat should I expect during all-day use?

Expect typical pneumatic-tool noise levels; the right-angle metal housing gets warm as compressed air expands through the 0.4 hp motor.

What compressor and hose setup do I need before this sander will run?

A compressor delivering at least 21 cfm at 90 psi with a 1/4 in NPT inlet and minimum 1/4 in hose is required.
