Diamond-Coated Drill Bits for PCB Drilling

In recent years, PCB manufacturers have faced significant challenges due to the machining of high-performance, advanced materials used across critical sectors such as telecommunications, defense, medical, and automotive industries.

Halogen-free materials, IMS, and laminates with various fillers have a substantial impact on the performance and lifespan of standard tungsten carbide drill bits typically used in PCB drilling processes. These materials often require reduced machining parameters and result in shorter tool life, leading to increased production costs and reduced process efficiency.

To maintain high-quality drilling standards while addressing these challenges, many manufacturers have transitioned to using diamond-coated drill bits, which offer:

✅ Extended tool life, reducing replacement frequency
✅ Consistent drilling performance on abrasive and complex materials
✅ Lower operational costs and reduced machine downtime
✅ Precise hole quality and dimensional accuracy, even in high-volume production environments

Diamond-coated drill bits are an ideal solution for overcoming the challenges associated with drilling advanced materials, enabling manufacturers to reduce production costs while maintaining quality and process stability.
