摘要： PURPOSE: To provide a borer, with which the facilitation of installation, the heightening of mounting strength and the improvement of operability are contrived. CONSTITUTION: The rotation of a core bit for machining and boring a matter to be bored 12 is driven by a bit-rotating motor 26. The axial feeding is manually possible by rotating a rotating driven shaft 30 through the operation of a feeding handle 31. In order to automatically control the running of a borer 10, plug parts 52 and 54 are inserted into socket parts 58 and 60. As for one socket part 58 and the plug part 52 fitted to the socket part 58, the stripping of the plug part 52 off the socket part 58 is checked at the checking position of an operating part 66, resulting in installing an accessory 36 onto a borer main body 32. By connecting the rotating output shaft 44 of a bit-feeding motor 34 with the rotating driven shaft 30 through the movement of a joint member 80, the rotation of the rotating output shaft 44 can be transmitted to the rotating driven shaft 30. Thus, the running of the borer 10 is automatically controlled by a controlling part 40.
