D | D | D | 55° Rhombic (Diamond) shape, offering a balance of profiling flexibility and back-edge clearance. |
N | N | N | 0° Negative clearance angle for a rigid double-sided profile (yielding 4 effective cutting edges). |
M | M | M | Standard mid-range precision tolerance regulating thickness and inner profile index limits. |
G | G | G | Double-sided configuration featuring a cylindrical center pin hole and molded chip breakers. |
Size / IC | 15 (\(15.5\text{ mm}\) cutting edge length) | 4 (\(1/2\text{ inch}\) Inscribed Circle) | The overall size classification of the internal profile tool pocket. |
Thickness | 06 (\(6.35\text{ mm}\) thickness) | 4 (\(4/16\text{ or }1/4\text{ inch}\) thick) | Vertical tool core height built to absorb deep radial deflection. |
Corner Radius | 12 (\(1.2\text{ mm}\) radius) | 3 (\(3/64\text{ or }1/32\text{ inch}\) per unit) | A thick 1.2 mm nose radius engineered to survive heavy scaling and high-feed cutting. |
