700 ft-lb air impact wrench

The Chicago Pneumatic CP8252-P is a 1/2-inch pistol-grip impact wrench driven by compressed air. It delivers 700 ft-lb of breakaway torque and 553 ft-lb of fastening torque for heavy-duty automotive and industrial fastening jobs. Industrial-duty rating and a 3/4-inch maximum bolt capacity suit professional technicians and maintenance crews who need reliable high-torque removal and installation.

Installation needs 25 cfm at 90 psi

Connect the tool to a 1/4-inch NPT air inlet using a minimum 3/8-inch hose that can supply 25 cfm at a steady 90 psi. Three speed settings let the operator match output to the task, while bottom exhaust directs air away from the workpiece. Undersized hose or pressure drops below 90 psi are the most common causes of lost torque and inconsistent speed.

Sustained output at 1400 impacts per minute

At free speed the wrench runs at 9,000 RPM and produces 1,400 impacts per minute, maintaining a power-to-weight ratio of 159.1 ft-lb/lb during extended use. The 105 dB sound level reflects continuous high-energy cycling, so hearing protection is advisable for long sessions. Steady air supply keeps torque stable rather than fading under load.

Questions about this item

How can I verify the CP8252-P is delivering its rated 700 ft-lb breakaway torque after installation?

Connect the wrench to a regulated 90 psi air supply with a minimum 3/8 in hose and 1/4 in NPT inlet. At free speed it should reach 9,000 RPM and produce 1,400 impacts per minute. If those figures are met, the tool is operating within its industrial-duty specification.

What accessories are included with the CP8252-P and what must I supply myself?

The wrench itself is supplied. You must provide a compressed-air source capable of 25 cfm at 90 psi, a hose of at least 3/8 in inside diameter, and a 1/4 in NPT fitting for the air inlet.

Which version of the CP8252-P should I choose for bolts up to 3/4 in?

The single model listed handles a maximum bolt capacity of 3/4 in, delivers 700 ft-lb breakaway torque and 553 ft-lb fastening torque, and offers three speed settings. No alternative capacities or versions are described in the product data.
