ABSTRACT:
A drill has a unitary drill bit and chuck structure that includes a drill bit and a chuck. The chuck encloses a portion of the drill bit and has a thread. A rotatable drive element having a thread engages the thread of the chuck. The chuck is heat shrunk onto the drill bit to form a unitary structure through direct bonding of the chuck with the drill bit.
