Aircat Pneumatic Tools 1120 Composite Impact Wrench | 650 (ft-lbs) Max Torque | 7500 RPM | 1/2" Square Drive

When a shop needs a straightforward 1/2" pneumatic impact for automotive and maintenance fastening, the AIRCAT 1120 1/2" Composite Impact Wrench delivers useful torque in a manageable composite-body tool. Its 650 ft-lbs maximum torque supports brake, suspension, bracket, underbody, and general repair work, while 750 ft-lbs of loosening torque helps free stubborn fasteners before run-down. The 7,500 RPM free speed gives technicians solid fastener speed for repeated service tasks, and the 9/16" bolt capacity provides a quick reference for the fastener size class AIRCAT assigns to this model.

The 1120 uses a hard-hitting twin hammer mechanism (an impact design that delivers two balanced blows per rotation for steady power transfer), making it a practical choice for mechanics who want reliable impact action without a larger high-torque tool. The 1/2" square drive fits common impact-rated 1/2" sockets used across repair bays, fleet garages, and maintenance benches. At 4.8 lbs. and 7.66" long, the composite housing keeps the tool manageable for daily fastening, while the rear-mounted forward/reverse power management lever helps control direction and output during removal and installation.

Applications:

• Automotive service: Removing and installing brake hardware, suspension brackets, underbody fasteners, engine-bay hardware, and general repair bolts within the tool's torque range.
• Fleet maintenance: Servicing pickups, vans, trailers, service panels, guards, mounts, and shop vehicles where 1/2" drive sockets are commonly used.
• Repair shops and tire bays: Supporting wheel-area service, component removal, and routine nut-and-bolt work with final torque verified by a calibrated torque wrench.
• Industrial maintenance and MRO: Running down and removing fasteners on machinery covers, fixtures, access plates, equipment frames, and maintenance benches.
• DIY garage and restoration work: Useful for experienced home mechanics working on rusted automotive hardware, suspension repairs, and restoration projects with the correct air supply.

FAQs:

• Q: What is the AIRCAT 1120 best used for?
  A: The 1120 is best used for general 1/2" drive automotive, fleet, and maintenance fastening. It fits jobs such as brake work, suspension hardware, brackets, panels, underbody bolts, equipment covers, and everyday shop repair tasks.
• Q: What does 750 ft-lbs of loosening torque mean?
  A: Loosening torque is the breakaway force available for removing tightened or stuck fasteners. The 650 ft-lbs maximum torque rating describes the tool's headline output, while the 750 ft-lbs loosening torque reflects its removal capability.
• Q: What size air hose should I use with the AIRCAT 1120?
  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 1120 be used for lug nuts?
  A: The 1120 can be used for many passenger-vehicle lug nut removal jobs when 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.
