I am starting to look into drilling holes in my waste board to attach clamps. I am experimenting with Inkscape and Estlcam to try to figure out optimal settings for drilling all of the 9mm holes with 2mm counterbore around them for threaded inserts.
I drew up two circles in Inkscape, each with line width 0.1mm. The outer circle has 11mm diameter and the inner is 9mm. My bit is 1/8" in diameter.
I import into Estlcam and set up two helical drills (outer 2mm deep and inner 12mm deep). The preview shows that it will take around 5 minutes to drill one hole. I am really new to this field, but it seems like an awfully long time… is this reasonable? If not, can you help me tweak my settings to speed this up?
Here is a screenshot of the Estlcam preview.
