When a 1/2″ impact wrench needs strong initial hit for frame work, truck repair, and stubborn service fasteners, the AIRCAT 1250-K 1/2″ NITROCAT Composite Twin Clutch Impact Wrench gives technicians high breakaway force in a reinforced composite-body tool. Its 950 ft-lbs maximum torque supports suspension, drivetrain, chassis, bracket, underbody, and equipment fasteners, while 1,300 ft-lbs of loosening torque helps break tight or corroded hardware free before run-down. The 8,500 RPM free speed keeps service work moving, and the 1/2″ square drive fits common impact-rated sockets used in automotive bays, fleet garages, truck shops, and MRO benches.The 1250-K uses a hard-hitting smooth twin clutch mechanism (an impact design that delivers strong initial torque for stubborn fastener removal), making it especially useful for heavy-duty frame work and medium to heavy-duty truck service. Its 4.50 lb. reinforced Body Armor housing keeps the tool manageable for repeated shop use, while the 8.25″ overall length gives it a familiar full-size 1/2″ impact profile. AIRCAT’s patented quiet tuned exhaust keeps noise to 86 dBA, and the patented flip-lever forward/reverse control allows quick direction changes during fastener removal and installation.Type: NITROCAT Composite Twin Clutch Impact Wrench | Model: 1250-K | Drive Size: 1/2″ Square Drive | Free Speed: 8,500 RPM | Bolt Capacity: 9/16″ | Impacts Per Minute: 1,000 IPM | Max Torque: 950 ft-lbs | Loosening Torque: 1,300 ft-lbs | Weight: 4.50 lbs. | Length: 8.25″ | Air Consumption: 8 CFM | Recommended Hose Size: 3/8″ | Air Inlet: 1/4″ NPT/BSP | Noise Level: 86 dBA | Vibration: 6.5 m/secFeatures:Provides 950 ft-lbs of maximum torque and 1,300 ft-lbs of loosening torque for high-output 1/2″ drive fastening and removal work.Hard-hitting smooth twin clutch mechanism creates strong initial torque for stubborn fastener removal.Reinforced Body Armor housing helps protect the tool body during regular shop, fleet, and truck-service use.Patented handle design supports controlled grip and handling during fastener 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.Twin clutch mechanism is better suited for heavy-duty frame work and medium to heavy-duty trucks.Applications:Medium and heavy-duty truck service: Removing and installing frame bolts, suspension hardware, brackets, mounts, guards, and chassis fasteners within the tool’s torque range.Automotive repair: Handling drivetrain bolts, suspension fasteners, underbody hardware, crankshaft bolt removal, and general service work where strong initial impact force is helpful.Fleet maintenance: Servicing pickups, vans, trailers, service vehicles, support equipment, and shop assets that use common 1/2″ drive impact sockets.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 repair, drivetrain service, and project vehicles with a properly sized air supply.FAQs:Q: What is the AIRCAT 1250-K best used for?A: The AIRCAT 1250-K is best used for 1/2″ drive fastening where strong initial impact force and high loosening torque are needed. Common jobs include frame work, medium to heavy-duty truck service, drivetrain repair, suspension hardware, underbody fasteners, and fleet maintenance.Q: What is a twin clutch impact mechanism?A: A twin clutch mechanism is an impact design that delivers strong, smooth initial torque. On the 1250-K, that helps remove stubborn fasteners such as frame bolts, crankshaft bolts, truck-service hardware, and corroded chassis fasteners.Q: What is the difference between maximum torque and 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. AIRCAT lists the 1250-K at 950 ft-lbs maximum torque and 1,300 ft-lbs loosening torque.Q: What air hose size should I use with this impact wrench?A: AIRCAT lists a 3/8″ recommended hose size for the 1250-K. 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 the AIRCAT 1250-K?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.AVAILABLE VARIATIONS AND SPECIFICATIONS SKUFree Speed (RPM)Bolt Capacity (in.)Square Drive (in.)Impacts Per MinuteMax.
