thread mill

[mielke]

any suggestions on drill hole size for a 1/2-13 thread mill. It'll be in 3/4" thick 304SS. We had some problems in the past with this material using a cut tread and had to open the hole larger than recomended.

from what i've seen you drill the the minor diameter size. anyone have any experience with this?

The thread mill doesn't cut the minor. You machine it first to be within the size limits required by the standard.
