Diamond Segment-Core Drill Bit- Reinforced Concrete
Product Introduction
The diamond segment for core drill bits is made of high-quality industrial diamond particles and precision-welded to the steel body through metallurgical bonding.
The optimized segment design ensures excellent cutting efficiency and wear resistance during high-speed drilling, making it suitable for reinforced concrete, asphalt, and masonry. Its thin-wall structure enables low vibration and clean holes, supporting efficient and precise drilling operations.
The diamond segment is the technologically advanced heart of modern drilling tools. Its performance directly affects the efficiency and quality of drilling into high-strength and abrasive materials. Through high-quality raw materials, metallurgical bonding technology, and optimized structural design, this segment provides professional drilling tools with stable, efficient, precise, and clean cutting performance.
Core Benefits
Technical Features
1. High-Quality Industrial Diamond Particles
The segment is made with carefully selected, high-quality industrial synthetic diamond particles. These diamonds act as the main cutting medium due to their hardness.
Benefits:
- High-quality industrial synthetic diamond particles
- Strong cutting ability
- Suitable for high-strength abrasive materials
- Provides the cutting foundation for core drill bits
2. Metallurgical Bonding Technology
The segment uses metallurgical bonding technology, a high-temperature sintering process conducted under controlled temperature and pressure. This process fuses the diamond particles with a special metal powder matrix.
Benefits:
- Dense and uniform structure
- Robust molecular-level bond
- Withstands centrifugal force from high-speed rotation
- Withstands frictional heat
- Withstands impact vibrations
- Helps prevent premature diamond loss
- Helps prevent segment cracking
3. Optimized Segment Design
Key parameters such as geometry, diamond concentration, and matrix formula are determined through scientific calculation and testing to balance cutting efficiency and wear resistance.
Benefits:
- Optimized segment geometry
- Optimized diamond concentration
- Optimized matrix formula
- Balance between cutting efficiency and wear resistance
- Stable performance during high-speed drilling
4. Self-Sharpening Mechanism
During drilling, the softer metal matrix wears away in a controlled manner, continuously exposing fresh, sharp diamond edges.
Benefits:
- Continuously exposes fresh diamond edges
- Maintains sharp cutting state during service life
- Helps prevent glazing
- Helps avoid efficiency loss
- Helps reduce overheating
5. Thin-Wall Cutting and Coolant Channel Design
The segment width and coolant channel design are important for drilling performance. Precise dimensional control helps achieve a thin-wall cutting effect and reduces contact area with the material.
Benefits:
- Thin-wall cutting effect
- Lower drilling friction
- Lower vibration
- Smoother operation
- Clean borehole wall
- Precise dimensions
- Minimal edge chipping
