Chicago Pneumatic 1/2 in air ratchet
The Chicago Pneumatic CP7829H is a 1/2 inch drive air ratchet wrench designed for industrial duty. It delivers 70 ft-lb of fastening torque at a free speed of 225 RPM. The tool weighs 2.7 lb and has an overall length of 10 7/8 in. It is built for professional mechanics and heavy-duty maintenance work.
Installation needs 90 psi and 4 cfm supply
Connect the 1/4 in NPT air inlet to a hose of at least 3/8 in diameter. The tool requires a steady 90 psi operating pressure and consumes 4 cfm of air. Side exhaust directs air away from the work area. A common issue is insufficient compressor capacity causing pressure drop and reduced torque output during sustained use.
Suits pros needing compact high-torque access
This ratchet fits tight engine bays and suspension points where impact wrenches cannot reach. The ball detent retainer secures sockets during high-vibration tasks. It is not for buyers who need cordless portability or torque values above 70 ft-lb. Technicians requiring continuous high-volume fastening may prefer a larger drive tool.

Questions about this item
How do I confirm the CP7829H is delivering 70 ft-lb at 225 RPM after setup?
Connect the tool to a 3/8 in hose at 90 psi, run it at free speed and verify it reaches 225 RPM; then apply a calibrated torque tester to confirm 70 ft-lb fastening torque.
What comes with the CP7829H and what must I supply?
The ratchet itself is included; you must provide a 3/8 in minimum air hose, a 1/4 in NPT fitting and a compressed-air source capable of 4 cfm at 90 psi.
Which drive size suits the CP7829H for my sockets?
The CP7829H has a 1/2 in square drive with ball-detent retainer, so choose 1/2 in drive impact sockets for a secure fit.
