Abstract
A parting/grooving insert formed of cemented carbide includes upper and lower surfaces of V-shaped cross-section adapted to mate with corresponding V-shaped walls of a holder. The walls form opposite sides of a slot in which the insert is frictionally held. One of the walls is formed on an elastically movable clamping arm of the holder which is elastically displaced away from the other wall when the insert is forced into the slot. Due to the elasticity of the clamping arm, the insert is frictionally secured. The upper and lower walls include recesses spaced apart by non-recessed portions of the respective surfaces of the insert which are engaged by the walls of the slot. Due to the presence of the recesses, the pressure acting on the non-recessed portions of the insert surfaces is increased.
