CUTTING TIP
摘要:
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).
