An internal broaching tool for broaching profiles delimited by a root and flanks in one aspect arranges a relief part between the toothed part and the calibration part. The calibrating broaching teeth in adjacent rows on the calibration part have a guiding flank (without a clearance angle or with a maximum negative clearance angle of 0.1°) and a cutting flank (with a positive clearance angle). The guiding flanks and the cutting flanks on the calibrating broaching teeth located behind each other in the direction opposite the broaching direction are alternately offset relative to each other in adjacent rows. The position, shape, and size of each guiding flank located downstream in relation to the direction opposite the broaching direction are associated with the position, shape, and size of the associated cutting flank (or the flank of the broaching tooth) in the preceding row.
