A cutting tool used for grooving and turning operations, where a cutting insert is removably securable in a blade-shaped insert holder. The insert holder includes an insert receiving slot having a longitudinally extending upper receiving slot surface with longitudinally separated single pairs of ridge type V-shaped lateral stopping and upper clamping surfaces, the planar surface components of which form different internal angles. The cutting insert includes an upper surface with a single pair of groove type V-shaped upper abutment surfaces longitudinally separated from two pairs of groove type V-shaped lateral abutment surfaces. Clamping contact occurs between the pairs of upper abutment and upper clamping surfaces, and lateral contact only occurs between one surface component of one of the two pairs of lateral abutment surfaces and one surface component of the pair of lateral stopping surfaces for cases of a sufficiently large side load on the cutting insert. |
