What is cutting tool insert
Cutting tool insert is a replaceable or indexable component installed on cutting tools (such as turning tools, milling cutters, drill bits, etc.), which directly participates in the cutting of workpiece materials.
It is a core component in mechanical processing (such as turning, milling, drilling, etc.), responsible for removing materials by shearing, extrusion, etc. to form the required part shape and precision.
Classification of cutting tool inserts:
1. By shape
Triangle (T type), square (S type), diamond (D type), circle (R type), etc. Different shapes affect the number of cutting edges and applicable scenarios.
2. By processing type
Turning inserts: used for external circle, end face or internal hole turning.
Milling inserts: used for face milling, slot milling or contour processing.
Drilling inserts: used for drilling or reaming.
3. By installation method
Invertible inserts: can be rotated to use another cutting edge after passivation, which is economical and efficient.
Welded inserts: carbide inserts are welded on the tool shank, which is low cost but cannot be replaced.
