1/2" industrial impact wrench
The Chicago Pneumatic CP6748EX-P11R is an air-powered impact wrench built for industrial duty. It delivers 800 ft-lb breakaway torque and 560 ft-lb fastening torque through a 1/2" square drive. The tool operates at 90 psi with 30 cfm air consumption and requires a minimum 3/8 in hose. ATEX certification for Zone 2 allows use in hazardous environments.
Sustained-load behaviour
At 90 psi the wrench maintains a free speed of 8,400 RPM and produces 1,200 impacts per minute. Three speed settings let the operator match output to the joint without changing supply pressure. The bottom exhaust directs airflow away from the workpiece while the tool runs continuously at its rated 90 psi maximum. Sound level reaches 104 dB during extended operation.
Air-supply limits
The 1/4 in NPT inlet and 30 cfm demand set the practical ceiling for compressor sizing. Pressure must stay at 90 psi; the specifications list identical minimum, operating and maximum pressures, so any drop below 90 psi reduces torque. A 3/8 in hose is the smallest recommended internal diameter to avoid flow restriction at the rated consumption.

Questions about this item
How loud is the CP6748EX-P11R when running at its 104 dB impact sound level all day?
The wrench produces 104 dB at the operator's ear during impacts, so hearing protection is required for continuous use in a workshop.
What compressor capacity and hose size do I need to supply the 30 cfm air consumption at 90 psi?
You need a compressor that can deliver at least 30 cfm at 90 psi with a minimum 3/8 in hose and a 1/4 in NPT inlet fitting.
Will the 1/2 in square drive and 800 ft-lb breakaway torque work with my older 1/2 in impact sockets?
Yes, the 1/2 in drive fits standard 1/2 in impact sockets, and the 800 ft-lb breakaway torque is within the rating of quality impact-rated sockets.
