Chicago Pneumatic Battery Torque Wrench | CP8613 WOB PACK 36V 2.5AH | 221 - 959 (ft-lbs) Torque Range | 3/4" Square Drive

Built for high-torque tightening on large fasteners without relying on compressed air, the Chicago Pneumatic CP8613 WOB PACK 36V 2.5AH Battery Torque Wrench delivers a 221 - 959 ft-lbs torque capability with ±4% accuracy. Its 3/4" square drive fits large industrial sockets, while the WOB configuration is supplied without reaction arm so the user can pair the tool with the correct compatible reaction accessory for the application.

The CP8613 WOB is part of the CP86 Series and uses a 36V 2.5Ah lithium-ion battery for cordless tightening in fleet, transportation, plant maintenance, and field service environments. The OLED digital screen provides tool-side torque setup, and the double-trigger starting system uses a second start button for more deliberate activation during high-torque work. With 10 RPM free speed and hard and soft joint capability, this tool supports controlled fastening on rigid metal-to-metal joints as well as assemblies with some compression from washers, spacers, or similar components.

Kit Includes:

• 1 CP8613 battery torque wrench
• 2 batteries
• 1 battery charger
• 1 charger cable
• 1 plastic case

Applications:

• Fleet and truck service - controlled tightening on large wheel, suspension, and chassis fasteners where torque accuracy matters.
• Bus and transit maintenance - cordless 3/4" drive fastening for high-use vehicle fleets and maintenance bays.
• Industrial maintenance and MRO - torque-controlled bolting on machinery, fixtures, frames, and production equipment.
• Field service operations - battery-powered torque work where compressed air setup is unavailable, inconvenient, or slower to deploy.
• Heavy equipment repair - fastening work on large service components where repeatable torque is preferred over impact-style rundown.

FAQs:

• Q: What does WOB mean on the CP8613 WOB PACK?
  A: WOB means the tool is supplied without reaction arm. A compatible reaction arm or reaction accessory must be selected separately based on the fastening setup.
• Q: Does this pack include batteries and a charger?
  A: Yes. This PACK version includes the CP8613 tool, 2 batteries, 1 battery charger, 1 charger cable, and 1 plastic case.
• Q: Is the CP8613 WOB an impact wrench?
  A: No. This is a battery torque wrench for controlled tightening. It is used when a target torque value and repeatability matter more than impact-style breakaway force.
• Q: Does this stand-alone model include connected reporting?
  A: No. This CP8613 WOB model provides digital torque adjustment at the tool, but connected CPLinQ, angle tightening, counting sequence, and Torque Check functions are reserved for C, CQ, and TC versions.
• Q: What reaction arm should be used with this tool?
  A: The correct reaction accessory depends on the fastener location, socket setup, and available reaction point. Confirm the compatible Chicago Pneumatic reaction arm or accessory before ordering this WOB configuration.
