Abstract:
A cutting tool has a cutting insert retained within an insert pocket of an insert holder by a retaining screw. Spaced apart first insert rear abutment surfaces abut spaced apart first pocket rear abutment surfaces, a second insert rear abutment surface abuts a second pocket rear abutment surface, and spaced apart insert lower abutment surfaces abut spaced apart pocket lower abutment surfaces. The cutting insert has a first dimension taken between extremities of the insert side surfaces, a second dimension taken between extremities of the insert upper and lower surfaces, and, a fourth dimension taken between the insert lower abutment surfaces and the insert upper surface. The size ratio between the fourth dimension and the second dimension is in the range of 0.2 to 1, and, preferably, in the range of 0.55 to 0.6. The size ratio between the first dimension and the second dimension is in the range of 1 to 2.
