Quick Change holders are one of the most important features of a FlexArm tapping Arm. The torque holder contains a built in clutch that prevents broken taps. It is important to note that FlexArm tapping arms do NOT require modules, only torque holders. With each arm purchase, you receive 5 free torque holders.
