When a 1/2″ impact wrench needs high breakaway force without excessive tool weight, the AIRCAT 1125 1/2″ Composite Impact Wrench gives technicians a strong pneumatic option for automotive, fleet, and shop maintenance work. Its 1,000 ft-lbs maximum torque supports suspension, brake, drivetrain, underbody, and equipment fasteners, while 1,250 ft-lbs of loosening torque helps break stubborn or corroded hardware free before run-down. The 8,500 RPM free speed keeps repeated fastening jobs moving, and the 1/2″ square drive fits the common impact-rated sockets used throughout repair bays, tire shops, and MRO benches.The 1125 uses a hard-hitting twin hammer mechanism (an impact design that delivers two balanced blows per rotation for steady power transfer), giving the tool strong removal capability in a compact 1/2″ drive body. At only 3.80 lbs. and 7.10″ long, it offers a useful power-to-weight combination for technicians who handle impact tools throughout the day. AIRCAT’s patented quiet tuned exhaust keeps sound output to 87 dBA, while the patented flip-lever forward/reverse control allows fast directional changes during removal, installation, and fastener run-down work.Type: Composite Impact Wrench | Model: 1125 | Drive Size: 1/2″ Square Drive | Free Speed: 8,500 RPM | Bolt Capacity: 9/16″ | Impacts Per Minute: 1,600 IPM | Max Torque: 1,000 ft-lbs | Loosening Torque: 1,250 ft-lbs | Weight: 3.80 lbs. | Length: 7.10″ | Air Consumption: 8 CFM | Recommended Hose Size: 3/8″ | Air Inlet: 1/4″ NPT/BSP | Noise Level: 87 dBA | Vibration: 4.2 m/secFeatures:Provides 1,000 ft-lbs of maximum torque and 1,250 ft-lbs of loosening torque for automotive, fleet, and maintenance fastening work.Hard-hitting twin hammer mechanism supports strong, balanced impact output during repeated fastener removal and installation.Durable composite housing helps keep tool weight down while supporting regular shop use.Patented handle shape supports controlled grip and handling during service work.Patented quiet tuned exhaust reduces operating noise to 87 dBA.Patented easy-operation flip lever allows quick forward and reverse changes during bolt removal and run-down.Light 3.80 lb. body helps reduce fatigue during frequent use compared with heavier impact wrenches in the same drive class.Applications:Automotive repair: Removing and installing suspension bolts, brake hardware, axle components, underbody fasteners, brackets, and drivetrain hardware within the tool’s torque range.Fleet maintenance: Servicing pickups, vans, trailers, service panels, guards, chassis hardware, mounts, and shop vehicles that use common 1/2″ drive impact sockets.Tire and wheel service: Removing passenger-vehicle and light-truck lug nuts when fastener condition and torque requirements are within the tool’s capability.Industrial maintenance and MRO: Running down and removing bolts on machinery covers, fixtures, equipment frames, access plates, and repair bench assemblies.DIY garage and restoration work: Useful for experienced home mechanics working on rusted hardware, suspension repairs, drivetrain service, and restoration projects with a properly sized air supply.FAQs:Q: What is the AIRCAT 1125 best used for?A: The AIRCAT 1125 is best used for 1/2″ drive automotive, fleet, and maintenance fastening where the job needs strong loosening torque in a relatively light pneumatic impact wrench. It is a strong fit for suspension work, brake hardware, drivetrain fasteners, wheel-area service, equipment panels, and general repair tasks.Q: What is the difference between max torque and loosening torque?A: Maximum torque is the tool’s headline output rating, while loosening torque is the breakaway force available for removing tightened or stuck fasteners. AIRCAT lists this model at 1,000 ft-lbs maximum torque and 1,250 ft-lbs loosening torque.Q: What air hose size should I use with the AIRCAT 1125?A: AIRCAT lists a 3/8″ recommended hose size for this model. Using the recommended hose helps maintain airflow so the tool can deliver proper speed and torque under load.Q: Can I use chrome hand sockets with this impact wrench?A: No. Use impact-rated 1/2″ drive sockets only. Chrome hand sockets are not built for repeated impact loads and can crack or fail when used with a pneumatic impact wrench.Q: Can the AIRCAT 1125 be used for lug nuts?A: Yes, the 1125 can be used for many passenger-vehicle and light-truck lug nut removal jobs when the fastener condition and torque requirement are within the tool’s capability. Final tightening should always be completed with a calibrated torque wrench rather than the impact wrench alone.AVAILABLE VARIATIONS AND SPECIFICATIONS SKUFree Speed (RPM)Bolt Capacity (in.)Square Drive (in.)Impacts Per MinuteMax.
