Thread Tapping Inconel w/000-123 tap

thread404-1798

Thread Tapping Inconel w/000-123 tap

Thread Tapping Inconel w/000-123 tap

(OP)
I perform Technical Cost Analysis for a major defense contractor. One of the vendors taps a 000-123 thread in Inconel. They are experiencing a 4-1 scrap rate by breaking taps in the part.  

We will be performing a Process Improvement workshop soon and I would like to be able to reduce the scrap rate.

What is the advice of the community?
