Diamond Cut Router Bit | Taiwan Carbide Tool Manufacturer | STARTECH
Diamond Cut Router Bit is designed to maximize flute life and chip evacuation efficiency.
The diamond-coated structure forms an extremely hard film on the cutting edge, delivering outstanding wear resistance and making it ideal for machining high-hardness materials. These bits minimize tool wear, maintain consistent product dimensions, and reduce the need for frequent adjustments—saving both labor and time.
CVD diamond coated router bit is suitable for all PCB materials, especially Carbon Fiber Boards, Ceramics Filler Board, Halogen Free PCB, High Tg PCB, Quartz Filler Board, etc. STARTECH supplies Diamond Cut Router Bit with dependable carbide tool manufacturing and application support.

Additional Service
We offer customized OEM / ODM services for router bits, including specifications, materials, and coatings. Our flexible manufacturing solutions are designed to meet diverse customer requirements and provide optimal performance for specific applications.
Features
- Ultra-high hardness (~10000 HV) – forms an extremely hard diamond film on the cutting edge.
- Exceptional wear resistance – significantly slows down tool wear for extended lifespan.
- Superior heat conductivity – prevents thermal damage and improves cutting stability.
- Low friction, smooth chip flow – enhances efficiency and reduces cutting resistance.
- High dimensional accuracy – maintains stable tool diameter, ensuring consistent product quality.
- Cost efficiency –the tool life lasts nearly 20× longer, meaning 1 diamond-coated bit can replace 20 router bits, resulting in higher cost-performance ratio.
- Reduced downtime – less frequent tool changes lower labor costs and improve process efficiency.
