When 3/8" impacts are not enough for larger shop fasteners, the Cleco CV-500P pneumatic impact wrench steps up to a 1/2" drive platform with 780 ft-lbs maximum torque for maintenance, overhaul, vehicle service, and general industrial fastening. Its pin anvil retention helps secure compatible impact sockets during repeated fastening cycles, overhead work, and removal jobs where socket retention matters more than rapid socket changes.
Part of the CV Composite Series, the CV-500P pairs 8,500 RPM free speed with 1,200 blows per minute for quick rundown followed by controlled impact power once the fastener begins resisting rotation. The twin hammer mechanism (an impact system that delivers balanced, repeated striking force for steady torque output) supports reliable fastening and loosening performance across production, repair, and MRO environments. With a 7.6" overall length and 4.8 lb tool weight, this 1/2" pneumatic impact wrench gives technicians stronger torque capability while remaining manageable for daily shop use.

Features:
- Powerful twin hammer mechanism delivers repeated impact force for fastening and removal work.
- Variable speed trigger helps the operator control rundown speed, fastener start-up, and loosening response.
- Pin anvil drive retention helps keep compatible impact sockets secured during repetitive or elevated fastening tasks.
- Composite housing reduces tool weight compared with all-metal impact bodies while supporting everyday shop handling.
- 1/2" drive size fits common impact sockets used for vehicle service, plant maintenance, assembly, and repair work.
- 8,500 RPM free speed supports fast bolt rundown before final torque or removal impact is needed.
- Balanced pistol-grip layout gives technicians a practical torque-to-weight combination for general industrial production, maintenance, and overhaul.

Tech Tip: To increase tool performance, extend tool life, and lessen repair costs, use it with a Filter-Regulator-Lubricator FRL)
Applications:
- Industrial maintenance and MRO: removing machine guards, brackets, covers, equipment fasteners, and service hardware during plant repair work.
- Automotive and fleet service: handling suspension, chassis, underbody, accessory, and general repair fasteners that call for a 1/2" impact wrench.
- Production and assembly: running down nuts and bolts on frames, fixtures, fabricated components, and light-to-medium equipment builds.
- Maintenance and overhaul shops: breaking loose worn or corroded fasteners during teardown, service, and reassembly operations.
- Garage and workshop repair: supporting equipment repair, restoration work, and general fastening tasks when used with impact-rated sockets and a properly sized compressor.
FAQs:
- Q: What is the difference between the CV-500P and CV-500R?
A: The CV-500P uses a pin anvil for more positive socket retention, while the CV-500R uses a retaining ring for faster socket changes. Both models share the same 1/2" drive size, 8,500 RPM free speed, 1,200 BPM impact rate, and 780 ft-lbs maximum torque rating. - Q: What does pin anvil mean on an impact wrench?
A: A pin anvil uses a pin-style socket retention method to help secure the impact socket on the drive. It is useful when the tool is used overhead, in repetitive production work, or in situations where the socket should stay locked onto the anvil. - Q: What air supply should be used with the Cleco CV-500P?
A: The CV-500P lists 40.5 SCFM air consumption, a 1/4" air inlet, and a 3/8" minimum hose I.D. Use clean, regulated, lubricated air and confirm the compressor can maintain the required flow during the way the tool will be used. - Q: Can this 1/2" impact wrench be used for lug nuts?
A: It may be used for many automotive and fleet lug nut applications when the fastener requirements fall within the tool’s torque range. Always follow the vehicle or equipment manufacturer’s torque procedure and use a calibrated torque wrench for final torque verification where required. - Q: Can I use chrome hand sockets with the CV-500P?
A: No. Use only 1/2" drive impact-rated sockets that match the pin anvil retention style. Chrome hand sockets are not made for impact loading and may crack or fail when used on an impact wrench.
