TCMT16T304 Cermet Inserts Uncoated Steel Finishing Indexable Cutting Tools
Features of cermet inserts :

  • TiCN cermet has a very high chemical stability.
  • Anti-stick knife and wear resistance is also much higher than the hard alloy. But also has better red hardness and anti-crescent crater wear performance, suitable for steel high speed processing and semi-finishing.
  • Cermet grades provide long tool life and excellent surface finish, combining toughness with superior wear resistance.
  • Very light cutting speed ,smooth chip removal, versatility


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.

Cermet Inserts are excellent for all machining applications where specifications for high surface quality, dimensional stability and tight tolerances must be adhered to. They guarantee long tool life with small to medium chip cross sections and uniform allowances, and are ideal for fine finishing, finishing and rough finishing of steel, sintered metal and ductile cast iron.It has a reinforced structure that provides excellent chipping resistance, reducing the wear on the insert and preventing sudden fracture.
High quality surface finish
The main components, TiC and TiN, have good BUE resistance as they have low affinity with work materials. Thus, machining with cermets brings high quality surface finish over extended periods of time.
High speed cutting
The main components, TiC and TiN, are more resistant to wear and oxidation at high temperature than WC (tungsten carbide), which is the main component of carbide tools. Because of excellent wear and oxidation resistance, cermet grades are less reactive with work materials and make stable high speed machining possible.
The substrate is coated by the PVD method with TiN, TiCN, and/or TiAlN. The end results are materials that are suitable for precision machining and machining of difficult-to-cut materials. Inserts in these grades are tougher and harder than carbide and come with precision sharp cutting edges. They even have superior toughness and sharper cutting edges than ultra micro-grain carbide grades, with excellent wear resistance and thermal crack resistance.
