Ingersoll Rand 7RLMC1 Inline Pneumatic Screwdriver | 1,200 RPM | 20 - 110 (in-lbs) Torque Range

Ingersoll Rand 7RLMC1 Inline Pneumatic Screwdriver combines a 1,200 RPM free speed with an adjustable cushion clutch and a 20–110 in-lb (2.3–12.5 Nm) torque range. The cushion clutch is a torque-limiting mechanism that helps regulate tightening force as fastener resistance increases, making the tool suitable for assembly operations requiring controlled screw installation. Part of the Ingersoll Rand 7 Series, this lever-start air screwdriver provides a practical fastening solution for production workstations, equipment assembly, and repetitive threaded-fastener installation.

The 7RLMC1 features an inline handle configuration that aligns the motor, transmission, and spindle along a straight axis for direct access to fastening points. Its 1/4" hex quick-change drive accommodates compatible screwdriver bits, while the 11.9" overall length and 0.9" side-to-center distance help operators reach screws positioned near surrounding components. Simple push-button reverse supports fastening and removal operations, and external torque adjustment allows clutch settings to be changed without disassembling the tool. With 27 CFM air consumption, this pneumatic screwdriver is suited to compressed-air assembly stations where consistent fastening procedures and adjustable torque control are important.

Applications:

• Industrial production assembly — installing threaded fasteners in repeated manufacturing operations using adjustable clutch settings.
• Automotive component assembly — fastening brackets, housings, and mechanical subassemblies within the tool's recommended torque range.
• Appliance and equipment manufacturing — securing screws on equipment panels, mechanical components, and assembled enclosures.
• Machinery assembly workstations — performing controlled screwdriving on components that require higher tightening torque than smaller assembly screwdrivers can provide.
• Industrial maintenance and repair — removing and reinstalling compatible threaded fasteners on equipment assemblies where pneumatic screwdriver operation is appropriate.

FAQs:

• Q: What is the torque range of the Ingersoll Rand 7RLMC1 screwdriver?
  A: The 7RLMC1 covers a combined torque range of 20–110 in-lb (2.3–12.5 Nm). The manufacturer's catalog lists 20–85 in-lb with the medium clutch spring and 25–110 in-lb with the heavy clutch spring. Select the appropriate clutch spring and setting for the fastening application.
• Q: How does an adjustable cushion clutch work?
  A: A cushion clutch is a torque-limiting fastening mechanism that helps control the amount of torque transmitted to the screw. It is commonly used for repeated assembly operations where adjustable tightening force is required. Actual fastening torque should be verified on the intended joint.
• Q: What size air hose is required for the Ingersoll Rand 7RLMC1?
  A: The manufacturer's specifications recommend a minimum 5/16" (8 mm) air hose and identify a 1/4" NPT air inlet. The listed air consumption is 27 CFM, so the compressed-air supply should be sized to meet the tool's operating requirements.
• Q: Can the 7RLMC1 be adjusted without taking the tool apart?
  A: Yes. The screwdriver allows external torque adjustments without tool disassembly. Changing between clutch spring ranges may require additional servicing, so consult the manufacturer's instructions before changing the spring configuration.
• Q: What is the difference between the Ingersoll Rand 7RLMC1 and 5RLNC1?
  A: The 7RLMC1 operates at 1,200 RPM with a 20–110 in-lb torque range and 27 CFM air consumption. The 5RLNC1 operates at 1,000 RPM with a 13–75 in-lb torque range and 16 CFM air consumption. The 7RLMC1 provides a higher maximum torque range, while the 5RLNC1 is an alternative for lower-torque fastening requirements.
