Abstract
An alignment structure for a wood flat drill bit comprises a flat drill bit and a connecting assembly. The drill bit has a flat drilling end and the other end of the drill bit is provided for positioning the connecting assembly. The connecting assembly and the flat drill bit are formed with conical portions for abutting against each other. Hence, the flat drill bit can be automatically aligned by abutting the conical portion of the flat drill bit against that of the connecting assembly.
