Abstract: Cutting inserts are assembled around the periphery of a holder of a tool by respective fastening screws. Each insert is seated against a support surface, and its respective fastening screw passes through a center hole in the insert and is threaded into a mounting hole formed in the support surface. The mounting hole is oriented non-perpendicularly to the support surface, whereby the fastening screw forms an angle with the axis of the insert's through-hole and is more accessible to a screwdriver. The through-hole has a conical or spherical portion which supports a spherical head of the fastening screw.

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.
