Engineering notes & guides.
Engineering-focused technical guides on in-die tapping technology, roll-form taps, model selection and die integration.
What is in-die tapping? Working principle and benefits
We explain step by step how in-die tapping technology — which eliminates the secondary tapping operation — works, what advantages it offers and how it differs from classic methods.

Why is a roll (form) tap mandatory? The difference from cutting taps
Why only roll-form taps should be used in in-die operation, and the effect of chipless tapping on strength, surface quality and tool life.
