My suggestion is, go buy some spade bit wood boring tools. You have a variety of widths to choose. Take a Dremel cut off wheel and cut the point off. Hollow grind them on the face of a grinding wheel, it takes a little practice to avoid overheating them. You can then use them as screw jacks with a ratchet in the drill press, make a wooden or Delrin handle, or with Chapman handles and a ratchet. This method dramatically reduces boogered screws.
Just my way of thinking after 50 years at the bench.

When James Flynn gives you information, you need to listen. These spade drills are forged and are made of high quality and tough steel.
40 years ago there was a TV commercial for the investment firm EF Hutton. "When EF Hutton talks everyone listens" Advise from James Flynn should be the same way.
If there ever was a person "who has been there and done that" it is Flynn.
