Homebrew PCBs

Ask anyone who has tried to drill out a PCB using standard high speed steel drill bits, or tried to mill a PCB with a high speed steel engraving bit.

If cutting on a tablesaw, I'd strongly recommend a carbide tipped blade. For drilling and milling, again carbide.

For cutting PCBs are other plastics I use a Freud Diablo non-ferrous cutting 10" blade on a table saw (carbide, 80 tooth as I recall) it has a very interesting tooth profile and a low, if not negative "hook".  Cuts plastic and aluminum plate like butter...virtually no burrs.
