drilling that chiaphua gear
We are planning to mount the chiaphua gear to a .25" shaft using a 1/16" roll pin, but we can't seem to drill through it. We got a cobalt bit, a good drill press, and plenty of drill oil, but that darn gear is so hard that 30 minutes of straight drilling at the highest pressure possible before the bit bends got us down about a millimeter. At this rate, each gear will take us 5 hours to drill. Does anyone have any suggestions on how to cut this thing?
