Cermet Turning Inserts

Cermet inserts are made of the ceramic bonded metal composite prepared by powder metallurgy. Cermet inserts compare to other materials, with the advantage of long tool life and excellent surface finish, combining toughness with superior wear resistance.

UKO Cermet Inserts are an enhancement to our general turning inserts, specifically designed for high-speed finishing. Compared to our Carbide inserts, Cermet inserts allow faster cutting speeds, with less deterioration and wear during uninterrupted cutting.

Cermet is a trend to use in CNC cutting processing in the future, UKO provides a standard type of cermet turning inserts such as TNMG/CNMG/WNMG/CCMT/TCMT/DCMT/DNMG, etc.

UKO’s cermet turning inserts grade is suitable for machining steel, powder metallurgy metal, difficult to process cast iron and stainless steel materials for superficing processing, finishing and semi-finishing.


  • The scope of application has different chip-breaking grooves and geometric bilateral and single-sided-side cermet blades, including amelioration blade.
  • Covered several standard blade-shaped cermet vehicles with chip-breaking grooves, which helps to select a more suitable Chip-Breaking Grooves for each chip-breaking grooves.
  • Chip-Breaking Grooves design is designed to be able to reliably chip-breaking in fully automated processing applications.

Cermets, especially Ti(C,N)-based Cermet Turning Insert, exhibit high chemical stability against the material being processed, resulting in the weakness of processing friction and the decrease of contact temperature, thus effectively preventing the interdiffusion of atoms between the tool and the work piece material and significantly improving the anti-adhesion wear performance.
Ti(C,N)-based Cermet Cutting Tools exhibit excellent red hardness and excellent resistance to crescent crater wear under high-speed cutting conditions.

What is cermet?2021-10-22T02:40:14+00:00

Cermet is made of metal and ceramic materials. It has both the advantages of metal and the characteristics of ceramics. Because of its high toughness, high hardness, and high oxidation resistance, it is highly regarded in rockets and high-speed aircraft.

The metal raw materials most commonly used to make cermets are iron, nickel, cobalt, etc. The most commonly used ceramic raw materials are oxides, silicides, borides, carbides, and nitrides. The production of cermet is also relatively simple. The firing method is the same as that of ceramics, except that the metal powder is mixed into the ceramic soil to produce different shapes according to requirements.

What is the difference between ceramic blades and cermet blades?

Ceramics have higher hardness than cermets, and cermets have better toughness than ceramics. The ceramic blade contains only ceramics, and the cermets are mixed with metal and ceramics. The cermets are for steel, cast iron, stainless steel finishing, semi-finishing

Ceramic blades are new-type blades made of high-tech nanotechnology. The sharpness is more than ten times that of steel blades. Therefore, ceramic blades have the characteristics of high hardness, high density, high-temperature resistance, magnetization resistance, and oxidation resistance.

The ceramic knife is developed using high-precision ceramic high voltage, so it is called a ceramic knife. Ceramic knives are known as “noble knives”. As a product of modern high technology, they have advantages incomparable with traditional metal knives; they use high-tech nano-zirconia as raw materials, so ceramic knives are also called “zirconium gem knives”. You can see it.

What grinding wheel is better for cermet blades?

First, the material of the abrasive must be diamond. For non-metallic hard and brittle materials, diamond is just against it.

Secondly, the cermet blade you mentioned may be a toughened cutting ceramic material. Generally speaking, resin diamond is good at grinding hard and brittle materials, but hard and tough materials tend to heat up during grinding. Efficiency and wheel life are not good,

Comprehensive consideration should be given to ceramic bonded diamond wheels, ceramic heat resistance, wheel life is good, and can ensure that the diamond is held under high cutting conditions, the high grinding efficiency is commonly used SDC wheels.

At present, most ceramic knives on the market are processed with a nano material “zirconia”. The zirconia + alumina powder was pressed into a mold blank with a weight of 300 tons, and then sintered at 2000 degrees Celsius. After grinding with diamond, it was equipped with a handle to make a finished ceramic knife.

HQ: Chip breaking groove type code.

What’s the difference between diamond blade and parallelogram blade in CNC turning tools?2021-09-28T06:32:30+00:00

The differences between D-type 50° diamond and C-type 80° diamond CNC turning tools are as follows:

The larger the sharp angle of CNC turning tool, the better the strength of the blade tip, the better the heat dissipation, the more suitable for heavy cutting, and the smaller the secondary deflection angle, which is conducive to improving the machined surface roughness.

D-type tooltip angle is relatively small, which can reduce the contact area between the tooltip and the workpiece during cutting, reduce the cutting force, and help to control the machining accuracy.

In addition, the C-type blade angle determines that it is suitable for both the outer circle and the end face, and has a wide range of uses. Type D is suitable for finishing or semi-finishing excircle and digging a certain range of grooves, but it is not suitable for flat end face (only small cutting depth).

Generally speaking, type C is widely used and everyone loves it. Similar to C-type, W-type (peach type) has double-sided 6 tips, but the angle is the same as C-type, which can reduce the cost.
