CUTTING HEAD AND CUTTING TOOL HAVING A REPLACEABLE CUTTING HEAD
Abstract:
A cutting head (21) for a cutting tool (101) includes a cutting portion (23) and a shank portion (25). The cutting portion (23) includes a plurality of integrally formed cutting edges (27) and the shank portion (25) has a first end (31) adjacent the cutting portion (23) and a second end (33). The shank portion (25) has a first portion (35) of the shank portion (25) having a first diameter, a second portion (37) of the shank portion (25) having a second diameter smaller than the first diameter, and a cylindrical third portion (39) of the shank portion (25) having a third diameter larger than the second diameter. The first portion (35) of the shank portion (25) is closer to the first end (31) of the shank portion (25) than the second and third portions (37 and 39) of the shank portion (25) and the third portion (39) of the shank portion (25) is disposed closer to the second end (33) of the shank portion (25) than the first and second portions (35 and 37) of the shank portion (25). The first portion (35) of the shank portion (25) has an exterior surface (41) including at least one axially extending recess (43) extending from an end (45) of the first portion (35) of the shank portion (25) closest to the second portion (37) of the shank portion (25) toward the first end (31) of the shank portion (25). The cutting head (21) is entirely formed of a pressed and sintered cemented carbide material. Furthermore, a cutting tool (101) is disclosed.
