Code Breakdown (ISO/ANSI Specification)
Every segment of this nomenclature dictates a specific physical attribute or operation style:
490 (Cutter Family): Designed specifically to fit CoroMill® 490 shoulder milling cutters.
14 (Size): Denotes a cutting edge length of 14 mm.
04 (Thickness): Dictates an insert thickness of 4 mm.
12 (Corner Radius): Specifies a corner nose radius of 1.2 mm.
M (Edge Profile): Indicates a medium-sized light-cutting geometry ideal for smooth machining transitions.
PM (Chip Breaker Style): Specifically engineered for primary workpiece steel and stainless steel applications, balancing edge security and lower cutting forces.
Technical Specifications
Hole Diameter: Features a 4.1 mm partly cylindrical fixing hole with a 40–60 degree countersink for secure mounting.
Rake: Utilizes a positive rake angle to reduce power consumption and heat generation.
Operation Type: Engineered for pre-machining with high demands on the final surface finish.
Compatible Grades: This insert geometry is combined with various material coatings depending on your specific thermal and hardness requirements, including grade variants like 1130, 4330, 3330, and 1030
