Document Type and Number:
Japanese Patent JP2016068544
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electric power tool that is able to shorten time taken for boring, thereby improving work efficiency, and is able to bore a hole having a highly accurate undercut without requiring skill.SOLUTION: An electric power tool body 1 is used for boring a hole having an undercut. The electric power tool body 1 comprises: a drive shaft 11 to which rotation of an electric motor 3 is transmitted; and a rotation member 10 comprising a drill bit 6 directly connected to this drive shaft 11. Having, as a fulcrum, the drive shaft 11 and a joint part 12 of the drill bit 6, the rotation member 10 is supported by guide means 15 so as to be able to swing. The rotation member 10 is inclined by the guide means 15, and also rotation of the electric motor 3 is transmitted to the guide means 15, thereby causing the rotation member 10 to rotate while revolving.SELECTED DRAWING: Figure 3
