Chicago Pneumatic 8941077826 Air Impact Wrench 1 in Drive

Product Description

The CHICAGO PNEUMATIC 8941077826 is a heavy-duty 1-inch drive air impact wrench designed for high-torque fastening and removal tasks in demanding shop and field environments. It delivers 2,150 ft/lb of torque at a free speed of 5,160 RPM, making it suited for heavy equipment, commercial truck, and industrial maintenance work. Air consumption is 10 CFM at 90 psi through a 1/2-inch NPT inlet. The tool features a D-handle configuration with directional exhaust, a built-in clutch mechanism, and a low-vibration design intended to reduce operator fatigue during extended use. Licensed HVAC techs, heavy equipment mechanics, fleet technicians, and industrial maintenance crews are the primary installers and operators of this tool.

This air impact wrench is built for heavy-duty applications where high output torque is required on large fasteners. Typical use cases include truck and bus wheel service, heavy machinery assembly and disassembly, agricultural equipment maintenance, and structural bolting work. The D-handle grip and directional exhaust make it practical in tight or confined service bays where managing exhaust airflow matters. The 500 blows per minute rating supports consistent performance on stubborn or corroded fasteners common in fleet and industrial settings.

Key Features

• 1-inch square drive for compatibility with heavy-duty impact sockets
• 2,150 ft/lb maximum torque output for large fastener applications
• 5,160 RPM free speed with 500 blows per minute
• D-handle design with directional exhaust for controlled airflow in enclosed workspaces
• Built-in clutch mechanism for controlled torque application
• Low-vibration construction to reduce operator fatigue during extended use
• Noise level rated at 111 decibels — hearing protection required during operation

Compatibility

Designed as a heavy-duty pneumatic impact wrench for use with standard 1-inch drive impact sockets and accessories on air supply systems capable of delivering at least 10 CFM at 90 psi through a minimum 1/2-inch inside-diameter air hose.

Installation Notes

This tool is operated by qualified mechanics and technicians familiar with pneumatic tool safety and applicable workplace safety codes. Before connecting to an air supply, verify the compressor and hose system can sustain at least 10 CFM at 90 psi and that the supply hose is rated for the working pressure. Use only impact-rated sockets and accessories rated for 1-inch drive at the torque levels this tool produces — standard chrome sockets are not suitable. Wear ANSI-rated hearing protection during operation given the 111-decibel noise level.
