I used to do woodgraining and to avoid having chips where the screws hold the parts, I always used a counter sink by hand to clear out the high build primer in the screw holes to keep the layers of paint (base and graining and clear) from being on a thick, softer substrate. I also put wax on the tapered part of the screws and didn't reef them down.
I also clean out lug stud holes of wheels after painting or powder coating. I had forgotten that step until Dale brought up the lug nut issue. I was just focused on the application. The right size counter sink in a cordless drill makes pretty quick work of it on wheels.
