Designed for precision fastening and high-volume assembly operations, the Ingersoll Rand 1RPMS1 inline air screwdriver delivers a 1,650 RPM free speed with an adjustable 4.4–20.4 in-lbs torque range for consistent fastening performance across a wide range of production applications. Equipped with an adjustable shut-off clutch and push-to-start activation, this pneumatic screwdriver helps achieve repeatable torque while minimizing the risk of over-tightening, making it well suited for quality-sensitive assembly processes.
Built for continuous industrial use, the 1RPMS1 combines an ergonomic inline design with an automatic shut-off clutch that disengages once the preset torque is reached, improving fastening consistency and reducing operator fatigue during repetitive tasks. The push-to-start mechanism streamlines operation by automatically engaging the tool when pressure is applied to the fastener, helping increase efficiency on production lines.
