In a broach for the surface finishing of workpieces set in a rotating movement for this purpose, the broach cutting edges (3) are parts of an interchangeably fastened cutting body (2) made of a hard cutting material. For the pull cut, the cutting edges (3) form an acute angle with the longitudinal broach axis (4) and are disposed at a nose angle (7) to one another which closes in the feed direction (6). The head of a separating body (12) inserted into the broach (1) and made of a wear-resistant material is arranged below the cutting body (2). The head of the separating body (12) forms a fin (11), running in the direction of the longitudinal broach axis (4), for the sharp separation of the two chip-flow chambers (9). <IMAGE>
