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.
