C C | C C | C 80° Rhombic (Diamond) shape, providing ideal balance between edge strength and contour flexibility. [1, 2, 3, 4] |
N N | N N | N 0° Negative clearance angle, requiring a tilted pocket to create relief and giving the insert double cutting sides. [1, 2, 3, 4] |
M M | M M | M Mid-range precision tolerance class regulating thickness and inner profile limits. [1] |
G G | G G | G Double-sided configuration featuring a cylindrical center pinning hole and built-in chip breakers. [1, 2, 3, 4] |
Size / IC 12 (\(12.09\text{ mm}\) effective edge) [1, 2, 3, 4, 5] | Size / IC 4 (\(1/2\text{ inch}\) Inscribed Circle) [1, 2, 3, 4] | Size / IC The overall size classification of the internal profile pocket. [1] |
Thickness 04 (\(4.76\text{ mm}\) thickness) [1, 2, 3, 4] | Thickness 3 (\(3/16\text{ inch}\) thick) [1, 2, 3, 4, 5] | Thickness Vertical height measurement of the solid carbide core. [1, 2] |
Corner Radius 08 (\(0.8\text{ mm}\) radius) [1, 2, 3] | Corner Radius 2 (\(2/64\text{ or }1/32\text{ inch}\) radius) [1, 2] | Corner Radius Rounded cutting tip profile that directly dictates final part surface finish. |
