Precision Material for High-Speed PCB Manufacturing In modern electronics manufacturing, especially in HDI (High-Density Interconnect) PCB production, micro drilling tools require extremely high levels of precision, stability, and wear resistance. Our ultrafine tungsten carbide rods are specifically engineered to meet these demands. With diameters starting from 0.1 mm, our rods are widely used in manufacturing PCB micro drills and micro end mills, supporting high-speed, high-volume production environments.

Why Our Carbide Rods Perform Better in PCB Applications

PCB manufacturers in the United States face increasing challenges:

  • Smaller hole diameters

  • Higher spindle speeds

  • Stricter quality requirements

Our solution is built around these realities.

Key Performance Advantages

  • Ultra-fine grain structure ensures superior edge sharpness

  • High wear resistance extends tool life

  • Excellent dimensional stability reduces vibration during drilling

  • Consistent material quality supports automated mass production


Improving Your Production Efficiency

Using high-quality carbide rods directly impacts your tool performance:

  • Reduced tool breakage during high-speed drilling

  • Longer tool life → fewer tool changes

  • Lower scrap rate

  • Better hole quality and consistency

👉 Result: Higher productivity and lower overall manufacturing cost
