When everyday shop fasteners call for more breakaway force than a mid-range 1/2″ impact can provide, the AIRCAT 1150 1/2″ Composite Impact Wrench gives technicians a strong pneumatic option for automotive, fleet, and maintenance service. Its 900 ft-lbs maximum torque supports suspension, brake, drivetrain, bracket, underbody, and equipment fasteners, while 1,295 ft-lbs of loosening torque helps break tight or corroded hardware free before run-down. The 9,000 RPM free speed keeps repetitive fastening work moving, and the 1/2″ square drive fits common impact-rated sockets used in repair bays, tire shops, fleet garages, and MRO benches.The 1150 uses a hard-hitting twin hammer mechanism (an impact design that delivers two balanced blows per rotation for steady power transfer), helping the tool deliver reliable removal force during repeated service work. Its 4.50 lb. durable composite housing keeps the wrench manageable compared with larger high-torque impacts, while the 7.50″ overall length gives the tool a familiar full-size 1/2″ impact profile. AIRCAT’s patented quiet tuned exhaust reduces sound output to 86 dBA, and the patented flip-lever forward/reverse control supports quick direction changes during bolt removal, installation, and fastener run-down.Type: Composite Impact Wrench | Model: 1150 | Drive Size: 1/2″ Square Drive | Free Speed: 9,000 RPM | Bolt Capacity: 9/16″ | Impacts Per Minute: 1,400 IPM | Max Torque: 900 ft-lbs | Loosening Torque: 1,295 ft-lbs | Weight: 4.50 lbs. | Length: 7.50″ | Air Consumption: 8 CFM | Recommended Hose Size: 3/8″ | Air Inlet: 1/4″ NPTFeatures:Provides 900 ft-lbs of maximum torque and 1,295 ft-lbs of loosening torque for high-output 1/2″ drive fastening and removal work.Hard-hitting twin hammer mechanism supports strong, balanced impact output during repeated fastener service.Durable composite housing helps control tool weight while supporting regular use in shop and maintenance environments.Patented handle design supports controlled grip and handling during removal, installation, and direction changes.Patented quiet tuned exhaust reduces operating noise to 86 dBA.Patented easy-operation flip lever allows quick forward and reverse changes during bolt removal and run-down.1/2″ square drive works with compatible impact-rated sockets for common automotive, fleet, and industrial maintenance fasteners.Applications:Automotive repair: Removing and installing suspension bolts, brake hardware, drivetrain fasteners, underbody components, brackets, and general service hardware within the tool’s torque range.Fleet maintenance: Servicing pickups, vans, trailers, shop vehicles, service panels, guards, accessory mounts, and chassis hardware that use 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 automotive hardware, suspension repairs, drivetrain service, and project vehicles with a properly sized air supply.FAQs:Q: What is the AIRCAT 1150 best used for?A: The AIRCAT 1150 is best used for 1/2″ drive automotive, fleet, and maintenance fastening where the job needs strong loosening torque from a pneumatic impact wrench. Common uses include suspension work, brake hardware, drivetrain bolts, wheel-area service, equipment panels, and general repair tasks.Q: What is the difference between 900 ft-lbs max torque and 1,295 ft-lbs loosening torque?A: Maximum torque is the tool’s headline output rating, while loosening torque is the breakaway force used to remove tightened or stuck fasteners. For installation work, final torque should always be checked with a calibrated torque wrench.Q: What size air hose should I use with the AIRCAT 1150?A: AIRCAT lists a 3/8″ recommended hose size for this model. Using the recommended hose helps maintain air volume 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 made for repeated impact loads and can crack or fail when used with a pneumatic impact wrench.Q: Can the AIRCAT 1150 be used for lug nuts?A: Yes, the 1150 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 Torque (ft-lb)Weight (lbs.)Length (in)Air Cons.
