This is an OEM chuck key and it is sold individually.The chuck key fits into a hole on the side of the chuck. The teeth are what help to hold the adjusting ring. As you rotate the key, the adjusting ring turns to tightly engage with the drill bit. This chuck key tightens jaws that have a 1/2-inch capacity. Over time, the teeth can deteriorate and this can cause the gear to slip. To make it easier to keep track of the chuck key, a chuck key holder can be ordered separately. It attaches to the power cord and the chuck key can be attached to it.
