High CBN content grade for high speed
BX950 3900 ~ 4100 1.80 ~1.90 machining
PCBN grade featuring high CBN content and
use of cobalt alloy binder. Grades
High CBN content grade with priority on wear
resistance and versatility
BX480 4100 ~ 4300 1.90 ~ 2.10 World’s highest content of CBN in a practical tool
material. Features the highest hardness level of
Superalloys
all the T-CBN grades*.
Super fine grain PCBN grade for machining
BX470 4100 ~ 4300 1.90 ~2.10 ferrous sintered metals
The highest content of CBN in the world as a
practical tool material*.
Coated grade for high-speed continuous and
light interrupted machining
BXM10 2700 ~ 2900 0.80 ~ 0.90 High crater resistance CBN substrate. The
Coated T-CBN surface is coated with a dedicated coating
material.
First choice: Coated grade for continuous and
interrupted machining and the removal of the
BXM20 3500 ~ 3700 1.35 ~ 1.50 carburized layer
Coated T-CBN High chipping resistance CBN substrate. The
surface is coated with a dedicated coating
material.
Coated grade for continuous to interrupted
machining
BXC50 3500 ~ 3700 1.15 ~ 1.30 Medium grained CBN particles are bound
Coated T-CBN with special binder. The surface is coated with
dedicated coating material.
High speed, continuous machining grade
BX310 2700 ~ 2900 0.80 ~ 0.90 The binding force between particles is
improved by using relatively coarse CBN
grains. Excellent wear resistance.
Hard
Materials
Super fine grained grade for superior surface
finish
BX330 2800 ~ 3000 0.85 ~ 0.95 Super fine grain CBN particles are bound
with a special binder. Maintains it’s very sharp
cutting edges.
General purpose grade for continuous to
ordinarily interrupted machining
BX360 3200 ~ 3400 1.00 ~ 1.10 Composed with fine grained and coarse
grained CBN particles. General purpose grade
featuring excellent impact resistance.

Tough grade for heavily interrupted machining
BX380 3500 ~ 3700 1.15 ~ 1.30 Composed of relatively high content of coarse
CBN particles. It contributes to the excellent
impact resistance.

Ultra fine grain PBN for superior surface finish
Features homogeneous and ultra fine grain
BX530 2800 ~ 3000 0.85 ~ 0.95 structure that is produced with Tungaloy’s own
manufacturing method. The worlds’ finest grain
PCBN*.
