HBA Grade

Carmex introduces HBA , a new extra-fine sub-micron grade with high toughness for optimized performance.
Threading of fully hardened and tough materials is increasing due to requirements
from manufacturers to avoid thread distortions and reduce the delivery time.
Thread turning inserts for machining materials harder than 40 HRc
require an optimized combination of carbide substrate, coating type
and edge conditions.
To meet this market need, Carmex is introducing HBA, a new extra -fine
sub-micron grade with high toughness, for optimized performance on:
  • Hardened Steels and Cast Iron up to 62 HRc.
  • Titanium Alloys and Super Alloys (Hastelloy, Inconel and Nickel base alloys).
  • High wear and heat resistance
  • Excellent edge stability
  • Unique coating structure
