Thank you for compliment LMMM
The reason for the 60° point is for visual purposes, that little bit of angle difference greatly increases the visual of locating the point of the center punch, I have always used a small pilot drill of no more than 3/32" to start with, then open the hole in increments to the final size, I am very aware of the proper 90° for a common center punches, even the common hand held center punches I have also have a steeper angle than 90° for that visual purpose, I agree that if someone wanted started with a 1/2" bit would create a walking problem.
Thanks for bringing that up LMMM I should have mentioned the small pilot drill is necessary first then open up the hole in increments.
Cheers LMMM
