Ingersoll Rand 4151 Air Orbital Sander 6 Inch 12000 Opm

Product Description

The INGERSOLL RAND 4151 is a pneumatic random orbital palm sander built for professional surface finishing work. It accepts a 6-inch round sanding pad and spins at 12,000 orbits per minute with a 3/16-inch orbit diameter, producing a fine, swirl-free finish on wood, metal, and composite surfaces. The sander draws 15.5 CFM of compressed air through a 1/4-inch NPT inlet and delivers 0.20 HP to the pad. At 1.92 pounds, the compact palm-style body reduces hand fatigue during extended use. Rear exhaust directs spent air away from the work surface, and the integrated vacuum port supports dust collection hookup.

This sander is suited for automotive body prep, cabinet and millwork finishing, and general metal fabrication in both shop and field settings. The palm-grip form factor makes it practical on flat panels, doors, and horizontal surfaces where a right-angle or pistol-grip tool would be awkward. Installers and tradespeople working in production environments benefit from the 12,000 OPM output, which allows fast material removal or finish passes without excessive dwell pressure. A minimum hose size of 5/16 inch is required to sustain adequate airflow during continuous operation.

Key Features

• Random orbital action with 3/16-inch orbit diameter for swirl-free surface finish
• 6-inch round pad accepts standard hook-and-loop abrasive discs
• 12,000 OPM operating speed for efficient material removal and finish work
• 1/4-inch NPT air inlet with 15.5 CFM consumption and 0.20 HP output
• Rear exhaust keeps spent air clear of the workpiece
• Vacuum-ready port supports direct dust collection hookup
• Compact palm-style body at 1.92 pounds and 7.48 inches overall length

Compatibility

Designed for use with standard 6-inch hook-and-loop random orbital sanding discs. Requires a compressed air supply capable of sustaining 15.5 CFM at adequate line pressure through a minimum 5/16-inch hose.

Installation Notes

Connect to a compressed air supply using a minimum 5/16-inch hose and a 1/4-inch NPT fitting. Depressurize the air line before attaching or removing the tool. Inspect the pad backing plate and hook-and-loop surface for wear before mounting abrasive discs. If connecting to a dust collection system, verify the vacuum port fitting size matches the collection hose adapter before operation.
