Zusammenfassung:	A drive tool for a bit including a support portion for supporting a drive article which has an upper part and a lower part of a drive shaft equipped with a handle and a holding part of the bit respectively, a base frame on which the support portion is coupled by a support axle so that it is rotatable back and forth and a bit having its shank held into the holding part, wherein forward-driving force caused by rotation of the drive article allows the operator to accurately judge the boring depth, while an angle scale on the base frame enables the operator to accurately judge the angle of inclination of the hole with respect to the object to be bored.
