Cutting a thread up to a shoulder
A problem with some thread dies is that they have such a large “lead in” that they are unable to cut a thread up to a shoulder.
This results in the thread stopping a long way from the shoulder… undesireable in some situations.
The solution? Modify the tool.
So that does the job.
The downside is that in future the thread must be started with the unmodified side of the die, and finished with the modified side. Adds some time. And the die is thinner and a bit weaker.
A pity that the dies are not manufactured with one “no lead in” face.
The particular set of ME dies will now all be modified in the same way.
