Grade ISO Grade Description Uncoated Layers Uncoated
P10-P30 A tough cermet grade, suitable for machining steels and stainless
M10-M20
CERMET IC30N steel at medium to high cutting speeds and low feeds. Features
excellent surface finish, very good wear resistance and prevents
built-up edge.
H10-H25 Base MATERIALS AND GRADES

K05-K15 A PCBN grade, suitable for finishing operations on hardened
IB55 steels (45-65 HRC) and cast iron in continuous cutting and light
interrupted cuts.
CBN H10-H25 Base

K01-K15
A PCBN grade, used for high speed machining of cast iron,
IB85 cemented tungsten carbide, sintered metals, and heavy alloys.
Excellent for interrupted cutting of hardened steel.
S05-S10
H05-H10 Base
A PCD brazed tip, suitable for machining aluminum alloys (Si <
12%) and other non-ferrous materials. Features very high wear
PCD ID5 N01-N10 resistance with high toughness.
Suitable for finishing operations and can be used for semi
roughing operations and interrupted cuts.
Base
