What this sander does
The Ingersoll Rand 317A is an air-powered disc sander built for medium-duty material removal and surface preparation. It accepts both 3 in and 5 in discs and runs at a maximum speed of 18000 RPM with variable speed control. The 0.45 HP motor delivers consistent power for automotive bodywork, metal finishing and woodworking tasks.
Installation and common issues
Connect the tool to a compressed air supply using the 1/4 in NPT inlet; a minimum 3/8 in hose is required to maintain the 15 cfm consumption at 90 psi. The threaded shank mount secures discs quickly, but cross-threading the pad is the most frequent error. No vacuum port is fitted, so dust extraction must be handled separately.
The spec that decides fit
The 0.45 HP rating and 15 cfm air demand determine whether your compressor can sustain operation. If the supply cannot maintain 90 psi at that flow, the sander will stall under load. Buyers needing lower air consumption or a built-in dust collection port should look elsewhere.

Questions about this item
How can I confirm the 317A sander is running at the rated 18000 RPM after I connect it?
Listen for smooth, steady motor tone at full throttle; the tool reaches its rated 18000 RPM when supplied with 90 psi at the 1/4 in NPT inlet and 15 cfm flow.
What accessories come with the 317A and what must I supply myself?
The box includes the sander body with both 3 in and 5 in threaded-shank pads; you must provide a 3/8 in minimum air hose, 1/4 in NPT fittings and a compressor delivering 15 cfm at 90 psi.
Which pad size should I choose for general-purpose sanding with the 317A?
Use the 5 in pad for larger surface coverage and the 3 in pad when working in tighter areas; both mount on the same threaded shank and run at 18000 RPM.
