A cutting tool having at least one segment pocket formed at a peripheral surface thereof, and respectively, at least one cutting tool segment, detachably mounted in each segment pocket. Each cutting tool segment has a longitudinal segment axis extending in a rearward to forward direction, and upper and lower ends, located on opposite sides of the segment axis. The lower end has two spaced apart lower abutment surfaces. An insert retention portion is formed in the upper end, at a forward end of the cutting tool segment. A resilient retention arm is formed in the upper end, rearwardly spaced apart from the insert retention portion. The retention arm has an upper abutment surface. In a side view of the cutting tool segment, the upper and lower abutment surfaces are linear. |

1. A cutting tool segment (100, 140, 100′) having a longitudinal segment axis (A) extending in a rearward to forward direction (DR, DF), and comprising:
an upper end (102) and a lower end (104), located on opposite sides of the segment axis (A), the lower end (104) having two spaced apart lower abutment surfaces (108, 110), an insert retention portion (112) formed in the upper end (102), at a forward end (114) of the cutting tool segment (100, 140, 100′); and a resilient retention arm (116) formed in the upper end (102), rearwardly spaced apart from the insert retention portion (112) by a resilience gap (117), the retention arm (116) having an upper abutment surface (118); wherein in a side view of the cutting tool segment (100, 140, 100′), the upper and lower abutment surfaces (118, 108, 110) are linear. |
