The Basics of Carbide Drill Bits
Introduction to Carbide Drill Bits
Superior Material
Excellent material base with superior toughness and high-temperature wear resistance.
Enhanced Efficiency
Customized precision grinding to minimize processing allowance and enhance production efficiency.
Performance Testing
Advanced analysis and testing services for tool failure analysis and material optimization.
1. Product Introduction
Hard alloy drill bit products are primarily used for deep hole, high-precision, and difficult-to-machine material hole processing. Solid round bars are used to manufacture solid drill bits, while single and double straight holes are suitable for processing various reamers and taps.
Double and triple spiral holes are utilized to create spiral internal cooling drill bits, which offer superior cooling effects and a service life more than double that of solid drill bits. Double-hole and kidney-shaped gun drill bits are designed for gun drills, used in deep hole processing with a diameter-to-depth ratio of 20 or higher, requiring auxiliary specialized equipment.
2. Product Advantages
- Excellent material base with superior toughness and high-temperature wear resistance.
- Comprehensive stock of spiral internal cooling tube materials and extrusion gun drill bits to meet various size requirements.
- Customized precision grinding and step difference services to minimize processing allowance and enhance production efficiency.
- Advanced analysis and testing services to provide tool failure analysis and material optimization for customers.
3. Product Performance
Hard alloy rod materials demonstrate excellent high-temperature resistance and impact toughness in hole processing, maintaining high wear resistance even under challenging heat dissipation conditions.
High-performance carbide drill bits in action
Spiral internal cooling hole tube materials exhibit high pitch consistency, with pitch fluctuations within ±0.3°, providing a solid foundation for deep hole drill preparation. Extrusion gun drill products offer excellent dimensional accuracy in oil holes and straightness, meeting the requirements for integral hard gun drills.
