Re: [CAD_CAM_EDM_DRO] Machineable wax problem

Bill,
I machine wax for jewellery too. The best way I've found to avoid the
chip problem is to use a twist drill as the cutting tool. Resharpen for
different tip profiles. I think that the helix on the drill is what does
the trick. I also have an air jet directed at the cut.
