Tungaloy Expands BXA20 T-CBN Inserts to Enhance Its Solutions for Hard Turning

Iwaki, March 2019 — Tungaloy adds a substantial number of new geometries and shapes to its BXA20 line, a successful grade of coated T-CBN inserts, designed to deliver efficient solutions to hard turning operations.

The BXA20 insert boasts a nano-multilayered PVD coating which is twice as thick as conventional grades and coated on a dedicated PcBN substrate with enhanced toughness. This adds both wear and fracture resistance to the grade, promising long and predictable tool life in continuous to interrupted cuts of hardened parts.

22 items are being added in this expansion, including inserts with wiper geometries and WavyJoint technology, to address a broader range of hard part turning needs.
