Abstract

Si tratta di un inserto per fresa forante bitagliente, monoinserto, a taglio parzialmente sferico. L'inserto ha due taglienti opposti (13, 14) ma non simmetricamente a cavallo di un piano diametrale di mezzeria del corpo-fresa e nella sua zona apicale (16), un primo tagliente (13) giunge fino in prossimità dell'asse di rotazione della fresa, mentre il secondo tagliente (14) è troncato con l'asportazione di un suo tratto (14') adiacente all'asse di rotazione.FIGURA 5.It is a bit-cutting, single-insert, partially spherical cutting insert for drilling. The insert has two opposite cutting edges (13, 14) but not symmetrically straddling a center line of the cutter-body and in its apical area (16), a first cutting edge (13) reaches up to near the axis of cutter rotation, while the second cutting edge (14) is truncated with the removal of a section (14 ') adjacent to the rotation axis.
