0.20 hp palm sander for detail work

The Ingersoll/Rand 4151-5 is a palm-style random orbital sander driven by compressed air. Its 0.20 hp motor delivers a free speed of 12,000 RPM for fine finishing on wood, metal or composite panels. The tool suits technicians and hobbyists who need a lightweight, manoeuvrable machine for contoured surfaces and tight corners.

3/16 in orbit and vacuum-ready dust control

A 3/16 in orbit diameter balances material removal with a swirl-free finish on 5 in PSA discs. Variable-speed control lets the operator match aggression to the substrate. The built-in vacuum port captures dust at source, though sustained heavy stock removal will exceed the 8.0 CFM average and 15.5 CFM full-load air demand of the 0.20 hp motor.

1/4 in NPT inlet and rear exhaust for shop comfort

The 1/4 in NPT air inlet requires a 3/8 in minimum hose supplied at 90 psi for rated performance. Rear exhaust directs airflow away from the workpiece and operator, reducing surface contamination. At 7 in overall length with a lever throttle, the sander fits comfortably in one hand for extended use, but the 5/16-24 spindle limits pad choices to the specified 5 in PSA format.

Questions about this item

Will the 0.20 hp motor and 12,000 RPM free speed keep up with my older 3/8 in air hose and 90 psi compressor?

The sander needs 90 psi and a minimum 3/8 in hose; at 90 psi it draws 8.0 CFM average and 15.5 CFM at full load, so your compressor must sustain that flow.

How can I confirm the 3/16 in orbit and vacuum port are working correctly after I hook it up?

Run the tool at 90 psi; the pad should produce a smooth 3/16 in random orbit with no visible wobble and the vacuum port should pull dust steadily through the rear exhaust.

Does the box include the 5 in PSA pad, 1/4 in NPT fitting and 3/8 in hose, or must I buy them separately?

The sander ships with the 5 in PSA pad installed; the 1/4 in NPT air inlet is built in, but a 3/8 in air hose and coupler are not included.
