CP7120 Driver Retainer

This driver retainer is a replacement component designed for Chicago Pneumatic tools. It secures the driver bit during operation, ensuring consistent engagement with fasteners. The part is supplied new and carries the manufacturer part number 8940159855. It is intended for maintenance of compatible pneumatic equipment.

For CP7120 tool owners

This retainer suits technicians who need to replace a worn or lost component on a CP7120 pneumatic tool. It restores the original holding function without modification. Shops working with other tool brands or different Chicago Pneumatic series should verify compatibility before ordering, as this retainer is specific to the CP7120 model.

CP7120 compatibility is the deciding factor

The retainer is engineered to fit the CP7120 part number exactly, matching the manufacturer's dimensions and locking mechanism. No other model is referenced in the specifications, so cross-referencing the tool's part number remains the only way to confirm fitment. If the tool carries a different identifier, this retainer will not suit the application.
