Ingersoll Rand 3955A2Ti Super Duty Air Impact Wrench | 1-1/2" Drive Size | 2750 RPM | 5000 (ft-lbs) Max Torque

Built for heavy equipment service, mining maintenance, oil and gas operations, and large-scale industrial bolting, the Ingersoll Rand 3955A2Ti Super Duty Air Impact Wrench delivers 5,000 ft-lbs of maximum torque for removing and installing the largest industrial fasteners. Featuring a 1-1/2-inch drive size and 2,750 RPM free speed, this pneumatic impact wrench provides the power required for high-torque applications involving heavy machinery, structural assemblies, and large mechanical components. Its Titanium hammer case construction reduces weight while maintaining durability for demanding field and maintenance environments.

The 3955A2Ti uses a TwinHammer impact mechanism (a dual-hammer design that delivers two balanced impacts per rotation for consistent torque output) and a pressure-feed lubrication system to support reliable operation during repeated heavy fastening tasks. The tool’s 1-1/2-inch drive configuration, ergonomic pistol grip design, and high torque capability make it suited for applications where standard impact wrenches cannot provide sufficient fastening power.

Type: Pneumatic Impact Wrench | Series: 3900 Super Duty Series | Drive Size: 1-1/2" Square | Handle: Pistol Grip | Impact Mechanism: TwinHammer | Free Speed: 2,750 RPM | Maximum Torque: 5,000 ft-lbs | Air Inlet: 1/2" NPT

FAQs:

• Q: What type of applications require a 1-1/2-inch drive impact wrench?
  A: A 1-1/2-inch drive impact wrench is typically used for large industrial fasteners found on heavy equipment, mining machinery, structural assemblies, and other high-torque applications.
• Q: What is the advantage of the TwinHammer mechanism?
  A: The TwinHammer mechanism uses two balanced hammer impacts per rotation to provide consistent torque delivery and reliable operation during repeated fastening tasks.
• Q: Is the 5,000 ft-lbs rating working torque or maximum torque?
  A: The 5,000 ft-lbs specification is the maximum torque rating. Actual fastening performance depends on the application, air supply, fastener condition, and operating conditions.
• Q: Why does this impact wrench use a titanium hammer case?
  A: The titanium hammer case helps reduce tool weight while maintaining the durability required for heavy industrial bolting applications.
