Drilling some .020 & .010 holes in Ultem. To peck or not to peck.
The .020 hole is .15 deep, the .010 is .22 deep and starts at the bottom of the larger hole. Feeding at 3ipm. currently pecking at .040 & .020 repectively. Both starting at .05 above. Of course I can start the .010 hole closer to the bottom of the .020 hole, but was wondering what y'all would do differently. Lots of holes, like to speed the cycle time some without breaking drills, or packing the tiny flutes with tinier angel hair chips. Right now the chip/strings are wrapping up the drill, like tiny hair balls. Using coolant for now.
