Product Description

The Bohrcraft INOX VAP Blue Ring machine tap DIN 371 HSS-E Co 5% Form B M 8 x 1,25 is specially designed for tapping through holes up to 3xD depth in stainless and acid-resistant steels (AISI 304 / AISI 316 / V2A / V4A). Its specialized rake geometry and steam-tempered black oxide finish (VAP) enhance cutting fluid retention and prevent cold-welding of stainless chips to the cutting edges. The Form B spiral point shoots chips cleanly forward through the bore.
