Tungaloy Substantially Expands BXA20 CBN Grade Inserts for Hard Turning

Iwaki, December 2019 — Tungaloy is adding 177 new shapes and geometries to its BXA20 line of coated T-CBN inserts designed for turning hardened steel parts.

The BXA20 insert has a nano-multilayered physical vapor deposition (PVD) coating, which has the twice as thick as conventional grades, and coated on a polycrystalline cubic boron nitride substrate. This adds wear and fracture resistance to the grade for longer tool life and improved predictability in continuous to interrupted cuts of hardened steel.

New shapes and geometries include -L, -LF, and -LC style edge preparations in addition to existing standard and -H edge preparations to address various needs of hard turning operations.

  • At a Glance:
    • BXA20 provides long and predictable tool life in continuous to interrupted cuts of hardened steel
    • Cutting edge preparations are available in 5 options for a variety of applications
    • A wide range of shapes and geometries for expanded coverage
    • Total of 177 inserts to be added
