This invention relates to a tool presetting gauge for adjusting the cutting edge of a tool fitted in a tool holder externally of a machine tool, or for measuring the position of the cutting edge. It comprises a gauge body with a support side and a bore parallel thereto for fixing the tool holder in a setting plane. The gauge body is provided with two surfaces which are parallel to each other and perpendicular to the support side. The distance between these two surfaces is equal to the distance between the support side and the axis of the bore and the setting plane, respectively. By setting the gauge body with one of the parallel surfaces on a table plate and applying the feeler of a dial gauge onto the other one of the two parallel surfaces the dial gauge can be set to zero. While the dial gauge is held stationary the gauge body is placed with its support side on the table plate, and by means of the feeler of the dial gauge it can be found out whether the tool is in the setting plane or must be adjusted.
