Abstract

A cutting tool has a main tool body and at least one insert seat disposed thereon. The seat has a bottom surface for mounting a cutting insert, and further has a dowel pin, which penetrates a through-hole of the mounted cutting insert and the bottom surface and can be fixed to the main tool body. A center longitudinal axis of the fixed dowel pin is arranged at an acute angle with respect to the bottom surface. The dowel pin contains a spherical segment for mounting on a bearing surface of the through-hole. The surface of the spherical segment is interrupted by a segment groove.

Embodiment Construction

[0030] figure 1 The cutting tool 1 shown is a tool for milling which comprises a tool body 2 . The head of the tool body 2 has a plurality of mounting points 3 for fastening exchangeable cutting inserts 4 . The mounting position 3 has a bottom surface 5 and a lateral stop surface 6 for positioning the cutting insert 4 . The cutting insert 4 has an octagonal cross-section with corresponding eight cutting faces 7 ( figure 2 ), whereby the cutting insert 4 is multi-purposed by means of the respective active cutting face 7 . The cutting insert 4 is pierced by a central through-hole 10 from a first upper surface 8 (generally the cutting face region) to a support surface 9 situated opposite the upper surface and facing the mounting position of the bottom surface 5 . The support surface 9 rests on the bottom surface 5 in the assembled position of the cutting insert 4 .

[0031] Each cutting insert 4 is fixed on the mounting location 3 by means of a locking pin, which is formed a...
