✅ 0.1-1.0mm and 1.1-2.0mm sets with 3.175 mm (1/8") shank
✅ Tungsten carbide construction for long-lasting sharpness
✅ Large chip clearance for smooth cutting and reduced resistance
✅ Long life: 2000-5000 holes per set under normal use; regrind 4-5 times
✅ Random color batches due to production variation
💡 What is a handy way to approach PCB drilling with tiny carbide bits? A practical answer is to pick the right size, maintain a steady feed, and keep the workpiece well-supported.
- Use the correct drill size for copper-clad boards to avoid loose or oversized holes
- Maintain a steady feed and clear chips to prevent wall defects
- Choose a 1/8 inch (3.175 mm) shank compatible with micro CNC tools
- Regrind or replace worn bits to extend life and precision
