This is an innovative item for drum tuning, providing a rotation speed as if driven by a motor, without the need for batteries. By holding the grip and rotating your wrist, the tip of the key rotates at 4 times the speed of your wrist, allowing you to change drumheads in a quarter of the time. Of course, it works in both directions, making head changes efficient. When loosening bolts, first rotate the grip only, and once it's slightly loose, rotate while holding the drive gear (the black part) to get the 4x speed rotation. The grip is ergonomically designed for use at any angle. ※ I also have many other drum equipment items for sale, please take a look ※ Condition: Only used a few times, so the condition is good, and the operation has been confirmed. There are minor scratches from use. Please check the condition in the images.
