Chicago Pneumatic torque wrenches are built for long-lasting accuracy—up to 25,000 cycles at 4% as per ISO 6789-1:2017. The fixed pear head ratchet features a robust 54-tooth mechanism allowing 6.6° increments. A non-intrusive audible signal indicates when the target torque is reached. Each wrench comes in a protective blow-moulded case with an ISO 6789 calibration certificate. The ratchet head includes a socket locking and quick-release system. The CP89 series includes six models, from ¼" to 1", covering a range of 5 Nm to 1,000 Nm (50 in-lbs to 750 ft-lbs).
