I have a part I am working on that is .250 thk aluminum. The problem I have is that when I pierce the hole I am out of the general tolerance on the bottom due to the blowout. My customer wants to reject this, The print is interpreted using Y14.5M-82. How would this be stated on a print that the hole size must be in tolerance all the way thru or is it assumed that the holesize must stay within the general tolerance block.
