Zhuzhou Century Tool manufactures premium Carbide PCB Twist Drill Bits with Fixed Shank Positioning Ring, designed for high-speed and high-precision drilling in printed circuit board (PCB) manufacturing. Manufactured from premium Tungsten Carbide Rods, our PCB drill bits offer exceptional hardness, superior wear resistance, and excellent dimensional accuracy for demanding electronic production environments.
Available in diameters ranging from 0.1 mm to 3.0 mm, these micro carbide drill bits are widely used for drilling FR-4, CEM-3, epoxy resin boards, fiberglass laminates, multilayer PCBs, aluminum substrates, and composite circuit boards. The fixed shank positioning ring provides consistent tool positioning during automatic tool changing, improving drilling accuracy and production efficiency in CNC PCB drilling machines.
As part of our complete range of Tungsten Carbide Drills, these PCB drill bits are engineered for long service life, high-speed operation, and stable drilling performance.
Each drill bit is manufactured from high-quality Tungsten Carbide Rods, ensuring exceptional hardness, high transverse rupture strength, and excellent wear resistance for continuous high-speed drilling.
The precision positioning ring allows accurate tool length control during automatic tool changes, reducing setup time and improving machining consistency.
Precision CNC grinding technology ensures excellent concentricity, minimal runout, and superior hole quality even in micro-hole drilling applications.
Optimized cutting geometry and premium carbide materials significantly reduce tool wear, providing longer service life compared with conventional HSS PCB drills.
The optimized spiral flute design efficiently removes chips and minimizes heat generation, reducing the risk of hole damage and drill breakage.
