The Vacuum Brazed Diamond Finger Router Bit is a high-performance diamond tool specially designed for stone processing applications. Manufactured with advanced vacuum brazing technology, diamond grains are firmly bonded onto the surface of a steel body through a high-temperature brazing process, forming a strong, wear-resistant diamond working layer.
Compared with conventional electroplated diamond router bits and sintered diamond tools, the vacuum brazed structure provides higher diamond exposure, stronger bonding strength, and faster material removal performance. During continuous machining operations, the diamond particles remain sharp and effective, significantly improving processing efficiency while extending tool

Features of Vacuum Brazed Diamond Finger Router Bit
Advanced Vacuum Brazing Technology for Superior Cutting Performance
The vacuum brazing process creates a strong metallurgical bond between the diamond particles and the steel body, providing:
- High diamond retention strength
- Reduced risk of diamond grain loss
- Excellent wear resistance
- Suitable for high-speed machining and continuous production
It is especially suitable for machining high-hardness stone materials and composite materials.
Professional Finger Router Design for Complex Profile Machining
The diamond finger router bit adopts a cylindrical working structure, allowing deep penetration into the material for precise machining. It is widely used for:
- Stone slot cutting
- Sink edge processing
- Countertop edge trimming
- Stone profile shaping
- Hole enlargement
- CNC stone milling applications
Compared with traditional grinding wheels, the finger router bit provides more flexible and accurate machining performance.
High Diamond Exposure for Improved Machining Efficiency
The brazed diamond layer provides a high level of diamond exposure, resulting in:
- Lower cutting resistance
- Better chip removal performance
- Faster material removal rate
- Reduced tool replacement frequency
It is ideal for automated processing and high-volume production environments.
