Built for precision fastening on production lines and assembly workstations, the Ingersoll Rand 1RTMS1 pneumatic pistol grip air screwdriver combines a 1,650 RPM free speed with an adjustable shut-off clutch and a 4.4–20.4 in-lbs torque range to deliver consistent fastening performance. The adjustable shut-off clutch (which automatically disengages once the preset torque is reached) helps reduce over-tightening and improves torque repeatability, making it well suited for applications where fastening consistency is essential. Its trigger and push-to-start actuation provides flexible operation for different production preferences while the pistol grip configuration offers familiar handling for repetitive fastening tasks.
Compact dimensions, a lightweight 1.5 lb design, and a coated grip help reduce fatigue during extended assembly cycles without sacrificing control. The 1/4" hex quick-change spindle allows rapid bit changes to minimize downtime, making the tool suitable for electronics, appliance manufacturing, automotive subassembly, and other light-to-medium torque fastening operations where repeatable results matter.
