Inline Air Screwdriver 1.5-30.0 in-lb

The Ingersoll-Rand 1RPNC1 is an adjustable cushion clutch air screwdriver built for industrial assembly and maintenance tasks. Its push-to-start throttle and reversible operation suit technicians who need controlled torque on fasteners. The 1/4-inch hex quick-change chuck accepts standard bits for rapid changeover.

Build Quality and Daily Use

An in-line body style keeps the tool balanced during extended runs at 1,000 RPM free speed. The 1/8-inch NPT air inlet and 1/4-inch minimum hose size connect to common shop supply lines. Average air consumption is 5.00 CFM at a 15-second run time and 13.0 CFM at full load, so compressor capacity must match demand.

Compatibility Check Before Ordering

Verify that your air system delivers 90 psi at the tool inlet under load. Ensure the hose and fittings support the required flow without excessive pressure drop. Confirm that the 1/4-inch hex drive matches the bits used in your application. Buyers who need higher torque or a pistol-grip form factor should consider other models.
