Technical Breakdown of the Part Number
A (Shape): Parallelogram-shaped insert with an 85-degree corner angle.
P (Clearance Angle): Features an 11-degree normal clearance angle, reducing friction against the workpiece wall.
M (Tolerance): Dictates standard metric manufacturing tolerances for thickness and indexing precision.
T (Hole & Chipbreaker Type): Indicates a single-sided insert featuring a cylindrical countersunk clamping hole and a specialized chip groove.
1135 (Size): Represents a cutting edge length of 11 mm and an insert thickness of 3.5 mm.
PDER (Geometry): Denotes a right-handed cutting direction with a standard parallel land and a positive rake angle for smoother cutting actions.
-H2 (Chipbreaker Topology): A specific reinforced chipbreaker geometry designed for roughing to semi-finishing operations, providing excellent chip control in sticky or tough materials.
CP1120H (Material Grade): A specialized, high-performance PVD-coated carbide grade. The physical vapor deposition coating offers extreme heat resistance and edge toughness, optimized for machining stainless steels, hardened steels, and high-temperature alloys.
