I need to drill a hole in metal for a 0-80 screw. So I bought a tap labeled 0-80. Then I looked at this chart: https://homerepairgeek.com/define/tap-drill-chart.html. I think it says to use a #50 or 52 drill bit, so I bought a #52. However after I drilled a hole with the #52 bit, I found that the hole is too large for the 0-80 tap. Did I do something wrong?
