💡 What are tungsten carbide micro drill bits best for in precision PCB and jewelry work? These tiny bits deliver clean holes with tight tolerances and good heat resistance.
- For PCBs, they create precise vias and features without burrs
- In jewelry, plastics, and acrylics, they cut smoothly with minimal heat buildup
- They work with most rotary tools and CNC machines when coolant is used
- Proper speed, feed, and clamping extend edge life and maintain accuracy
