Jiffy has developed 20V cordless tools for installing and removing frangible collar fasteners, including Eddie Bolt® style fasteners. These units are brushless and sparkfree, all based on the Modular Jiffy Mounting system, allowing ultimate flexibility in matching the accessories to the application.

The 27830 model delivers 225 in-lbs of maximum torque and the 27860/27861 models deliver 600 in-lbs of maximum torque.

Testing shows that with a fully charged battery, this tool is capable of tightening 2100 bolts (cycles).  We define a cycle as fastening and removing six fasteners to max torque, which counts as one cycle. The tool is then left idle for one minute before repeating the process until the battery is consumed. These tools accept all Jiffy JMI attachments (check applicable torque range).

These units have been popular with AOG (aircraft on the ground) crews dispatched to make repairs, not knowing the availability of air to run their tools, and eliminating the hose trip hazard.
