Cleco CWM-500R Pneumatic Impact Wrench | CWM Metal Housing Series | 9,000 RPM | 1,200 BPM | 1/2" Retaining Ring Drive | 850 (ft-lbs) Max Torque

When 1/2" drive fastening calls for a metal-housing impact wrench with fast run-down speed and strong breakaway power, the Cleco CWM-500R Pneumatic Impact Wrench gives maintenance crews, assembly teams, and repair shops a practical balance of torque, durability, and socket-change convenience. Its 850 ft-lbs max applied torque supports higher-load bolting than the 3/8" CWM models, while the 1,201 ft-lbs max breakaway torque helps remove tightened, rusted, or stubborn fasteners during repair and teardown work. The 9,000 RPM free speed speeds up fastener run-down before impact loading, and the 1,200 BPM impact rate delivers repeated hammer blows for controlled pneumatic fastening power.

Part of the CWM Metal Housing Series, the CWM-500R uses a triple heat-treated twin hammer mechanism (an impact system that delivers two hammer strikes per rotation for balanced torque transfer) inside a durable all-metal housing. The 1/2" retaining ring drive helps hold sockets securely while still allowing faster socket changes than a pin anvil style, making this model a strong fit for industrial maintenance, equipment service, fabrication, fleet repair, and production bolting stations where socket sizes change throughout the shift.

Applications:

• Industrial maintenance and MRO: loosening and installing fasteners on machinery bases, guards, frames, conveyors, pumps, and production equipment.
• Fleet and vehicle service: handling common 1/2" drive fastening work on trucks, service vehicles, brackets, suspension components, and shop repairs within the tool’s torque range.
• Fabrication and structural assembly: running down bolts on fixtures, welded frames, tooling plates, and metal assemblies where higher torque is needed than a 3/8" impact can provide.
• Equipment repair and teardown: removing tightened or stubborn fasteners before inspection, rebuild, or replacement work.
• Production bolting stations: supporting repeated fastening operations where operators benefit from retaining ring socket changes across multiple fastener sizes.

FAQs:

• Q: What is the difference between the CWM-500R and CWM-500P?
  A: The CWM-500R uses a 1/2" retaining ring drive, while the CWM-500P uses a 1/2" pin anvil or pin hole drive. Choose the retaining ring version when faster socket changes are important, and choose the pin anvil version when stronger socket retention is preferred.
• Q: Is 850 ft-lbs the same as breakaway torque?
  A: No. The 850 ft-lbs figure is the torque range maximum, while the catalog lists 1,201 ft-lbs as breakaway torque. Breakaway torque is the loosening force used to remove stuck or tightened fasteners.
• Q: What does a retaining ring drive do?
  A: A retaining ring drive uses a ring on the anvil to help hold the socket in place. It is commonly selected when operators need secure socket engagement but still want to change sockets more quickly than with a pin-retained anvil.
• Q: What size air setup should be used with this impact wrench?
  A: The CWM-500R lists 39.8 SCFM air consumption, a 1/4" air inlet, and a 3/8" minimum hose I.D. Use a compressor, air line, and FRL sized to maintain stable airflow during repeated impact cycles.
• Q: Can this tool be used in a repair garage?
  A: Yes, when the garage air system can support the tool’s airflow requirement and the job matches a 1/2" drive impact wrench. For smaller fasteners, a 3/8" impact may offer better control; for very large fasteners, a 3/4" or 1" drive model may be required.
