Product Description
Technical details, material information and manufacturing notes for this product.
1. Cemented Carbide Rod Overview
Cemented carbide rod is a solid cylindrical material made from tungsten carbide powder and metallic binder.
It is the basic raw material for high-performance cutting tools used in metalworking industries.
Compared with high-speed steel, carbide rods provide higher cutting speed and longer tool life.
Main Material Characteristics
High hardness and excellent wear resistance ensure stable performance in high-speed machining.
Good thermal resistance allows cutting under high-temperature conditions.
High rigidity reduces tool deformation during deep cutting operations.
2. Rod Types and Configurations
Solid Carbide Rods
Solid rods are used for standard milling cutters and punching tools.
They provide stable structure and high strength for general machining applications.
Coolant Hole Rods
Single, double, or helical coolant holes are designed for internal cooling tool systems.
These structures improve chip removal and reduce cutting temperature during deep hole machining.
3. Performance Advantages
High Rigidity and Stability
Cemented carbide rods have much higher stiffness than steel materials.
This reduces vibration and improves machining accuracy.
Wear Resistance and Tool Life
Tools made from carbide rods maintain sharp edges for a long time.
This reduces tool change frequency and production cost.
Precision Machining Performance
High density material structure ensures smooth cutting and stable surface finish.
