Precision Carbide Gun Drill Bit Set, 0.1-1.2mm for CNC PCB

High-precision machining

Adopt advanced equipment for precision machining to ensure the drill bit has superior performance and high precision.

Excellent cutting performance

With excellent cutting and milling performance, it effectively improves processing efficiency.

High hardness and wear resistance

Carbide material provides excellent wear resistance and bending resistance, ensuring that it is not easy to damage after long-term use.

Optimized chip removal design

The drill bit design has enough space for chip removal, reducing resistance, heat and pollution during processing.

Sharp cutting edge

The sharp cutting edge reduces cutting force, reduces breakage rate, and improves hole wall quality.

Symmetrical cutting edge

Symmetrical cutting edge ensures accurate drilling and avoids inaccurate drilling due to offset.
