APKT insert are versatile cutting tools widely used in industrial milling operations. These inserts play a crucial role in various machining processes, offering efficiency and precision across different materials and applications.

APKT Insert Specification:

АПКТ is a specific designation for a type of insert shape and geometry.
А stands for the insert shape, which is typically a parallelogram or rectangular shape with specific relief angles.
P refers to the tolerance class of the insert.
K designates the chipbreaker style, which affects how chips are formed and evacuated during the cutting process.
Т often indicates the insert thickness or a specific feature related to the insert’s design.

Key Features of APKT Inserts

Geometry: APKT inserts have a triangular shape with a positive rake angle, designed for optimal cutting performance.
APKT Insert Sizes: The most common sizes include:
- APKT 1604: A versatile size suitable for many applications
- APKT 1003: A smaller option ideal for more precise milling tasks
Material Compatibility:
- APKT 1604 inserts for steel: Engineered to withstand the rigors of milling ferrous materials
- APKT insert for aluminum: Designed with specific geometries to prevent built-up edge and ensure smooth chip evacuation.
Versatility: APKT inserts can be used for face milling, shoulder milling, and other cutting operations across various industries.
Indexability: Each insert typically has three cutting edges, allowing for multiple uses before replacement.
Material Composition: Usually made from carbide, often with specialized coatings to enhance performance and longevity.
APKT Insert Sizes and Applications:
- APKT 1604: Commonly used for general-purpose milling in medium to large-scale operations
- APKT 1003: Preferred for smaller milling cutters or when working with tighter tolerances
Performance Characteristics:
