    PCB Engraving Bits  0.005”  /  0.005”, 10 Pack  /  0.003”  /  0.003”, 10 Pack  We recommend the PCB Engraving Bits for milling traces in PCBs and the Metal Engraving Bits for traditional engraving applications with other materials. Engraving bits are great for milling traces in PCBs because they are incredibly durable. You can mill traces in a fraction of the time with engraving bits vs traditional flat end mills. To learn more about isolation milling PCBs with engraving bits, check out our support guide here: Engraving Bit Isolation Milling. The 0.005" tip diameter PCB Engraving Bit is capable of milling boards with 0.010" spacing. The 0.003" tip diameter bit is capable of milling boards with spacing as small as 0.006" when used with the Bantam Tools Desktop PCB Milling Machine or Othermill PRO.                                                                 https://www.bantamtools.com/products/pcb‐engraving‐bits 3‐7‐18
