Abstract

The present invention relates to a hand grinder, and more particularly, to a multidirectional bendable hand grinder which can freely switch the power transmission direction in a refractive manner in order to establish various workpiece surface machining directions, and in which the extension and twisting action of the length of a grinder body enable grinding work to be easily performed on the inner surface of the workpiece. The hand grinder according to the present invention comprises: a power device for rotating a machining member mounted at the front end thereof to machine the workpiece; a control module which controls the power device to control the rotation direction and the number of rotations of the machining member; a first joint and a second joint which switch the advancing direction of the power device to vary the machining angle of the workpiece; a first body which accommodates a portion of the power device, and which adjusts the gap between the first joint and the second joint and the angle of the machining member; a second body which accommodates another portion of the power device, and which enables a worker to hold the second body by the hand thereof; and a gripping body which is assembled at the outer surface of the first body, and which enables the other hand of the worker to hold the gripping body at a free angle and position.
