💡 What is a common use for PCB drill bits in CNC engraving and drilling?

PCB drill bits are handy for precise, clean holes in PCBs and similar materials.

- Tungsten carbide tips resist wear and heat during high-speed drilling - Suitable for PCB boards, acrylic, aluminum, and soft metals with CNC engravers - Large chip clearance reduces heat and ensures clean, accurate holes - Best results come from vertical drilling with steady feed speed
