JINXIN PCB carbide rod features ultra fine grain structure, excellent wear resistance and high precision tolerance. Suitable for manufacturing PCB drills, micro end mills and miniature precision cutting tools.





JINXIN PCB carbide rod is specially developed for high-precision electronic manufacturing industries. With the rapid growth of PCB production, semiconductor processing and electronic component manufacturing, the demand for micro carbide rod products continues increasing worldwide.
The tungsten carbide drill rod is manufactured using ultra fine grain carbide powder and advanced sintering technology. The carbide micro rod provides excellent hardness, high transverse rupture strength and stable dimensional accuracy for miniature cutting tool production.
PCB drill bits require extremely high precision because modern electronic circuit boards contain very small holes and dense wiring layouts. The carbide rod for PCB drill production must maintain stable microstructure and precise diameter tolerance to ensure reliable drilling quality.
JINXIN PCB carbide rod products are widely used in printed circuit board manufacturing industries for producing micro drill bits ranging from 0.1mm to 3mm diameter. High-speed PCB drilling machines operate at extremely high spindle speeds, requiring cutting tool materials with excellent rigidity and wear resistance.
The micro carbide rod is also suitable for producing miniature engraving tools, dental burs, precision reamers and micro milling cutters. In medical industries, carbide micro rod products are used for manufacturing dental machining tools and surgical cutting instruments requiring high precision and corrosion resistance.
In electronic industries, tungsten carbide drill rod products are used for machining smartphone components, semiconductor molds, precision connectors and micro electronic parts. Fine grain carbide structure improves cutting edge sharpness and reduces tool vibration during micro machining operations.
The carbide rod for PCB drill manufacturing undergoes strict quality control including grain size inspection, hardness testing, microstructure analysis and precision grinding inspection. Every PCB carbide rod must meet strict concentricity and straightness requirements.
JINXIN micro carbide rod products are available in unground rods, centerless ground rods and customized precision tolerances. Surface polishing and H5/H6 grinding tolerances can be provided according to customer requirements.
Compared with ordinary carbide materials, the tungsten carbide drill rod used for PCB tools provides better anti-vibration performance and longer drilling life. Stable carbide structure helps prevent drill breakage during high-speed operation.
The carbide micro rod is also widely used in watchmaking industries, jewelry engraving and optical component machining. Precision industries require extremely stable cutting performance and dimensional accuracy.
JINXIN continuously develops advanced ultra fine carbide technology to improve wear resistance and toughness balance. The PCB carbide rod maintains excellent machining performance even under demanding high-speed drilling conditions.
Global electronic manufacturing industries increasingly require high-quality carbide rod for PCB drill production. JINXIN provides stable quality, fast delivery and customized solutions for precision electronic tooling manufacturers worldwide.
