Abstract:, A drive tool for a bit comprising a support for supporting a drive article which has a drive shaft equipped with a handle on the upper part and equipped with a bit holding part on the lower part, a base frame on which said support is rotatably coupled by a support axle, and a bit. The bit is held in the holding part and its driving-forward force caused by a rotation of the drive article allows an object to be boxed. A depth scale placed on the support enables the operator to discern the boring depth, while an angle scale on the base frame makes it possible to discern the angle of incline of the hole with respect to the object being bored.
