Descripción
Tools, usually having a straight or tapered shank, designed for piercing, perforating, or making or enlarging a hole, especially when piercing by means of a rotatory movement; common examples include tools for boring through rocks or through wood. For tools used for piercing or making holes, but having a fluted or spiral shank, use "drills (tools)."
