Chicago Pneumatic Battery Torque Wrench | CP8613TC WOB PACK 36V 2.5AH | 221 - 959 (ft-lbs) Torque Range | 3/4" Square Drive

Built for high-torque fastening programs that require cordless mobility, torque checking, and traceable process control, the Chicago Pneumatic CP8613TC WOB PACK 36V 2.5AH Battery Torque Wrench delivers a 221 - 959 ft-lbs torque range with ±4% accuracy. Its 3/4" square drive fits large industrial sockets, while the WOB configuration is supplied without a reaction arm so the correct compatible reaction accessory can be selected for the fastener location and available reaction point.

As the Torque Check version of the CP8613 WOB, this model supports torque tightening, torque check, angle tightening, counting sequence functions, and data collection for traceability through CPLinQ. The OLED digital screen gives technicians tool-side setup, while the 36V 2.5Ah lithium-ion battery platform keeps the wrench mobile around fleet bays, transit shops, plant equipment, and field service work. The double-trigger starting system adds a second start button for more deliberate activation during high-torque tightening.

Kit Includes:

• 1 CP8613TC WOB dual-trigger battery torque wrench
• 2 batteries
• 1 battery charger
• 1 charger cable
• 1 plastic case

Applications:

• Fleet and truck maintenance - torque-controlled tightening and torque checking on large vehicle fasteners where service records matter.
• Bus and transit shops - cordless 3/4" drive fastening across high-use vehicle fleets and maintenance lanes.
• Industrial maintenance and MRO - documented tightening on machinery, frames, fixtures, and plant equipment.
• Field service operations - battery-powered torque work where compressed air setup is unavailable, inconvenient, or too slow to deploy.
• Heavy equipment repair - large-fastener work where the reaction accessory must be selected to match the available reaction point.

FAQs:

• Q: What does WOB mean on the CP8613TC WOB PACK?
  A: WOB means the tool is supplied without a reaction arm. A compatible reaction arm or reaction accessory must be selected separately based on the fastener location, socket setup, and available reaction point.
• Q: What does the "TC" version add?
  A: "TC" identifies the Torque Check version. It supports torque check functions, angle tightening, counting sequence capability, and data collection for traceability through CPLinQ.
• Q: Does this pack include batteries and a charger?
  A: Yes. This PACK version includes the CP8613TC WOB tool, 2 batteries, 1 battery charger, 1 charger cable, and 1 plastic case.
• Q: Is the CP8613TC WOB an impact wrench?
  A: No. This is a battery torque wrench for controlled tightening and torque checking. It is used when target torque, accuracy, repeatability, and process documentation matter more than impact-style breakaway force.
• Q: When should I choose WOB instead of a model with an included reaction bar?
  A: Choose the WOB version when the job requires a specific reaction accessory that is not included in the standard kit. This is useful when the reaction point, socket length, clearance, or fixture layout requires a custom accessory selection.
