Ingersoll Rand 8506-APR-A Pneumatic Air Screwdriver | 600 RPM | 8 - 70 (in-lbs) Torque Range | Adjustable Cushion Clutch

Fastening larger screws and threaded components during production assembly requires a screwdriver that combines controlled rotation with sufficient torque for the joint. The Ingersoll Rand 8506-APR-A Pneumatic Air Screwdriver delivers a 600 RPM free speed and an adjustable 8–70 in-lbs (0.9–7.9 Nm) torque range, making it suitable for assembly operations requiring higher tightening torque and a more deliberate fastening speed. Part of the QRT Series, this pistol-grip screwdriver features an adjustable cushion clutch that limits torque transmission as the fastener tightens. Its Quick Reverse Touch Control (QRT) system enables convenient one-handed operation when fasteners need to be removed, repositioned, or realigned during assembly.

The 8506-APR-A combines trigger and push-to-start actuation in forward rotation with a separate reverse trigger that provides immediate full-power reverse. This arrangement supports production tasks where operators frequently alternate between installing and backing out fasteners. Measuring 8.9 inches (226 mm) in overall length and weighing 3.1 lbs (1.4 kg), the tool offers a pistol-grip configuration for assembly benches and manual fastening stations. Its 1/4-inch hex quick-change drive allows compatible screwdriver bits to be exchanged conveniently, while 24 CFM (678 L/min) air consumption, a 1/4-inch NPT inlet, and a 5/16-inch (8 mm) recommended hose diameter provide the specifications needed to plan the compressed air supply. The manufacturer lists an 82 dB(A) sound level for the QRT Series.

Features:

• Adjustable cushion clutch provides torque-limiting operation for repetitive fastening applications involving plastics, composites, and metals.
• 600 RPM free speed offers controlled fastener rundown for assembly tasks where a lower rotational speed is preferred.
• Broad 8–70 in-lb torque adjustment range accommodates different joint requirements within the screwdriver's rated capability.
• Quick Reverse Touch Control provides simple two-finger forward and reverse operation for fastener installation and rework.
• Trigger and push-to-start forward actuation allows the operator to initiate fastening through the designated starting arrangement.
• Separate reverse trigger provides instant full-power reverse for backing out or realigning fasteners.
• 1/4-inch hex quick-change drive allows efficient bit changes when working with different compatible screw heads.
• Pistol-grip configuration supports practical handling and positioning at assembly benches and production workstations.
• 8.9-inch overall length and 0.9-inch spindle offset provide useful dimensions for assessing clearance around fixtures and assembled components.

Applications:

• Industrial production assembly: Tightening threaded fasteners within the specified torque range during repetitive manufacturing operations.
• Mechanical component manufacturing: Installing screws in housings, brackets, covers, and other suitable metal assemblies.
• Plastic and composite assembly: Fastening components where adjustable torque limitation helps manage joint tightening requirements.
• Equipment manufacturing: Installing larger screws and threaded components that require more torque than lower-capacity assembly screwdrivers.
• Assembly rework: Removing or realigning fasteners using the dedicated full-power reverse control.
• Manual fastening workstations: Supporting production tasks that require regular bit changes, controlled rundown, and frequent direction changes.

FAQs:

• Q: What is the torque range of the Ingersoll Rand 8506-APR-A?

  A: The manufacturer specifies an adjustable torque range of 8–70 in-lbs (0.9–7.9 Nm). This is the highest published adjustable torque range among the QRT cushion-clutch models listed in the referenced catalog. Verify the required tightening torque on representative production joints before use.

• Q: Why would an assembly operator choose the 600 RPM 8506-APR-A instead of a faster screwdriver?

  A: The 8506-APR-A offers a lower free speed and a higher maximum torque setting than the faster 8509-APR-A and 8515-APR-A models. It is a useful option when the joint requires more tightening torque and a slower approach to seating. The best choice depends on the fastener, joint material, and assembly process.

• Q: Does the adjustable cushion clutch automatically shut off the air motor?

  A: No. A cushion clutch is a torque-limiting clutch rather than an automatic shut-off clutch. It limits transmitted torque as the fastener tightens, but the operator must release the trigger or remove the starting pressure to end operation. Applications requiring automatic shut-off should use an appropriately specified shut-off screwdriver.

• Q: How does Quick Reverse Touch Control help during assembly?

  A: QRT provides convenient two-finger control of forward and reverse rotation. The screwdriver operates with trigger and push-to-start actuation in forward rotation, while the separate reverse trigger provides immediate full-power reverse for removing or repositioning fasteners.

• Q: What bit connection does the 8506-APR-A use?

  A: The screwdriver uses a 1/4-inch hex quick-change drive. Select compatible fastening bits that match the drive connection and the fastener head. Confirm any special bit-holder or extension requirements before ordering accessories.

• Q: What compressed air supply is recommended for the 8506-APR-A?

  A: Ingersoll Rand lists 24 CFM (678 L/min) air consumption, a 1/4-inch NPT air inlet, and a recommended 5/16-inch (8 mm) hose diameter. The compressor and air distribution system should maintain the manufacturer's specified operating pressure during production fastening.
