Abstract
The invention concerns a cutting tip (6) comprising: a core (10) that extends axially; and at least a first branch (12) and a second branch (14) that extend radially from the core (10), each comprising: a proximal portion (12a, 14a) connected to the core (10), a distal portion (12b, 14b), and a central portion (12c, 14c) connecting the proximal portion (12a, 14a) and the distal portion (12b, 14b); and a cutting edge (12d, 14d) extending at least along the distal portion (12b, 14b) and the central portion (12c, 14c); in which: the distal portion (12b) of the first branch (12) is arranged radially forward relative to the central portion (12c) of the first branch (12); and the central portion (14c) of the second branch (14) is arranged radially forward relative to the distal portion (14b) of the second branch (14).
Claims20
A cutting insert designed to be fixed to one end of a tool body in order to be driven in rotation around an axis, including:
- an axially extending core;
- and
- at least a first branch and a second branch radially extending from the core, the first branch and the second branch comprising each:
- a proximal portion connected to the core, a distal portion, and a central portion connecting the proximal portion and the distal portion;
- and
- a cutting edge extending on at least the distal portion and the central portion;
- wherein:
- the distal portion of the first branch is disposed radially forward with respect to the central portion of the first branch;
- and
- the central portion of the second branch is disposed radially forward with respect to the distal portion of the second branch,
- wherein the cutting insert includes at least a third branch comprising:
- a proximal portion connected to the core, a distal portion, and a central portion connecting the proximal portion and the distal portion;
- and
- a cutting edge extending on at least the distal portion and the central portion,
- the third branch having a different profile from the profile of first and the second branches.
