16: Represents the size of the insert, corresponding to an IC (Inscribed Circle) of 3/8 inch (9.525 mm).
ER / IL: Refers to the physical hand and mounting compatibility. It fits External Right-hand (ER) or Internal Left-hand (IL) tool holders
1.6: Denotes the precise cutting width of the groove, which is 1.6 mm. This is typically used for machining specific standard retention rings or circlip slots.
LDA: Specifies the specialized PVD/CVD hard alloy coating. This grade offers exceptional adhesion resistance, thermal shielding, and chip control.
Performance Characteristics
Material Versatility: Highly optimized for ISO material groups P (Steel), M (Stainless Steel), and K (Cast Iron).
Tungsten Carbide Core: Features a high-hardness core (typically around 92 HRA) to withstand heavy structural stress and minimize edge wear.
Tooling Compatibility: Seamlessly integrates into standard laydown threading and grooving shank systems using standard 16ER or 16IL pockets .
