Drill chart Hole Tolerance
« on: July 28, 2019, 11:16:41 am »
Hi the drill chart is missing the hole tolerance and I'm unsure what tolerance to use.
The hole diameters range from 12 to 40 mils.

Is there a standard hole tolerances to use?
If a hole size is 25mils can it's tolerance be specified as -0 +7mil 

thanks
