I'm having a very frustrating issue appear seemingly out of nowhere.

I have a 1.375 extruded square part.

I create a legacy counterbore with the thru-all option.

Instead of creating a hole through my part, it leaves a .004 wall.

If I set my blind depth to 1.380 (greater than .004), it will create an actual hole.

This has never been an issue before, I do this virtually every day.

Thank you,
