1. Double-sided chipbreaker PM with M-level tolerance has higher strength of cutting edge. It is suitable for semi-finishing under unstable working conditions as well as machining cast iron with small cutting forces.
2. CVD coating has a peculiar gradient cobalt-rich on surface of the substrates which can ensure the inserts high performance.
3. The coating materials are MT-TiCN0-Al2O3 with thickness of 14μm, which have high abrasion resistance. After special management on the surface of the coating inserts, the internal stress and surface of coating were reduced while cutting resistance was also cut down.
4. CVD coated carbide grade,Universal grade,suitable for steel and cast continuous cutting and interrupted cutting finishing to roughing.

MaterialMaterial Characteristics
Carbon Steel, Alloy Steel and Tool Steel 36-48 HRC:

• Higher carbon content
• Higher chrome, nickel, and moly content
• Tough material to machine
• Abrasive
• Difficult to break and control the chip flow
• The material surface will harden when machined at high speed
• Good surface finish

Ferritic, Martensitic, and PH Stainless Steel under 48 HRC

• Brittle
• Stringy chips
• High cutting force
• The material will harden when machined at high speed.

Austenitic Stainless Steel:

• Becomes gummy under machining operations due to nickel content
• Very difficult to machine in soft conditions
• Very difficult to machine at a small depth of cut
• Develops a tough string of chips that are difficult to control. Forms a build-up on the insert tip
• Low thermal conductivity results in excess heat at the insert tip
• Material surface will harden due to high chromium content

Ductile and Malleable Cast Iron• Very difficult to machine • Small depth of cut • Spherical form graphite makes machining difficult • The carbide concentration creates hard spots • The material structure is not uniform • The crater wear and flank of the insert makes machining difficult • The insert tool life is less than gray cast iron
Gray Cast Iron

• Flake form of graphite makes machining easy
• Contains scale, inclusions and sand in the surface
• The material will break easily on the end of the cut
• Tendency to chatter and vibrate on thin wall section
• Chucking and rigidity of the workpiece is extremely important to minimize distortion, to achieve a good finish and close tolerance.
