P
M
Coated carbide. CVD — TiC-TiCN-TiN. Tri-phase coating on a hard, low binder K
CG6 content, fi ne-grained grade. High-speed, general-purpose grade for all kinds of steel.
Gold in color.

HC-P10
P
M
A PVD-TiN-coated grade. Straight 9.5% Co substrate. Submicron grain. For
CG5 general-purpose machining of most steels, stainless steels, high-temperature alloys, K
titanium, irons, and non-ferrous materials. Performs best at low speeds and will
handle interruptions and high feed rates. N
S
HC-S25
P
A PVD-TiN coating over a very wear-resistant, unalloyed carbide substrate. For M
general-purpose machining of most steels, stainless steels, high-temperature alloys,
Grade CG55 titanium, irons, and non-ferrous materials. Grade provides combination of high K
edge strength and wear resistance. Coating increases wear resistance and reduces
problems with built-up edge. The substrate offers superior thermal deformation
resistance and depth-of-cut notch resistance. S
HC-M20

PcBN tip brazed onto a carbide insert. Recommended for machining hardened steel
CBN6 (45–65 HRC). Use on bearing steel, hot and cold work tool steels, high-speed steels,
die steels, case-hardened steels, carburized and nitrided irons, and some hard
coatings. Can be run both dry and wet.

BN-H25 H

Polycrystalline diamond (PCD) compact grade provides exceptional hardness and
CPD1 abrasion resistance. CPD1 is a superior fi nish boring grade that will signifi cantly
improve workpiece tolerances, surface fi nishes, and insert tool life in high-silicon
aluminum, copper, aluminum carbon graphite, hard rubber, plastics, and/or wood. N
