Best tool bits for PCB cut outs (board shapes and slots) when prototyping with desktop CNC milling machine?
I use proprietary LPKF tools from PreciseBits
For contour routing (board outline) I use &quot;Chip-breaker Router Bits (RCC08) - (fish-tail, 0.125&quot; shank)&quot;
For general milling I use 0.0071n (0.18mm) dia, 3-flute 15° tapered stub bit, 0.010in DOC, 1.42in OAL, ZrN coated, 1/8in shank
I hope this helps
