Cermet cutting material grade with impressive performance during finish turning
Coating update for cermet CTEP110-P grade
Reducing the cost per part can be difficult in many industries. When considering quality, you need tools with the best cutting materials. Cermet cutting inserts are an alternative to carbide indexable inserts for finishing steel. As they are more heat-resistant than their carbide counterparts, they allow for higher cutting data and therefore shorter processes. They are also reliable with longer tool life and dimensional accuracy: Cermet inserts offer increased tool life, especially if they also have a high-performance DRAGONSKIN coating including wear detection - such as our new CTEP110-P grade.
Are you looking for high cutting speeds and long tool life when finishing steel? Cermet cutting materials, such as the new CTEP110-P from CERATIZIT, make it possible.
With four chip breakers, the cermet grade is a good all-around choice for medium and finish machining ensuring optimum chip control even for small depths of cut.

DRAGONSKIN coating on CVD basis
We are one of just a few manufacturers who offer CVD-coated cermet indexable inserts. Why do we do this? Although CVD layers are highly complex to produce, they offer enormous advantages for finish machining of steel compared to PVD coatings such as higher temperature resistance and better wear resistance. What’s more, CVD-coated cermet indexable inserts offer a wider application range and are ideal for dry machining.
We have even optimized a few aspects during the development of the new DRAGONSKIN coating for cermet grade CTEP110-P. Thanks to a special post-treatment process, we have significantly reduced surface roughness. The distinctive texture of the TiCN layer and the Al2O3 layer ensures better wear resistance and toughness.
Overall, we have been able to reduce the grain size within the individual layer systems. Flaking layers are now a thing of the past due to stronger bonding layers with our new DRAGONSKIN coating. With wear detection, machine operators can quickly identify if an insert needs to be indexed or replaced.
Ideal insert utilization thanks to updated coating with wear detection
As wear on the cutting edge can be quickly detected, the new cermet indexable inserts can get maximum utilization while avoiding tool breakages.
Earlier versions of this insert with coating did not have insert wear detection
The CTEP110-P is an updated version that includes both - a coating update as well as the insert wear detection layer
Four chip breakers for steel machining
A total of four chip breakers makes the new CTEP110-P cermet grade an all-around choice for medium and finish machining and ensures optimum chip control – even for small depths of cut. For negative indexable inserts in the range: -CF20 as a fine chip breaker with sharp cutting edge and ideal chip control. -TFQ for very high surface quality or high feed rates.
We have also widened our range for positive indexable inserts. First there is the periphery-ground, sharp finishing geometry -CF05, which ensures a high level of geometrical accuracy and dimensional stability with very low cutting forces. And then there's also the -CF55 for excellent chip control and versatile use.
Good to know: What does cermet mean?
The term cermet is derived from the words “ceramics” and “metals” and describes a composite material consisting of ceramic material in a metal matrix. It was developed in order to combine the properties of ceramics (oxidation and heat resistance) with the properties of metals (toughness and impact resistance) to create a better cutting material. The first cermet was developed back in 1931 by Paul Schwarzkopf and J. Hirschl and patented by PLANSEE. Over the years, the toughness of cermet has been improved while retaining the positive wear characteristics.
In contrast to classic carbide, cermet is based on titanium carbide instead of tungsten carbide. Cermet was originally a combination of TiC and nickel. More modern cermets are virtually nickel-free and have a structure of core particles of titanium carbonitride Ti(C, N), a second hard phase of (Ti, Nb, W)(C, N) and cobalt as a binder.
Why choose cermet?
Cermet offers a number of advantages over carbide in specific applications. For example, inserts can be used at very high cutting speeds and still provide long tool life. Cermets do not need coolant and it is even recommended to run them dry. Cermets are also the optimum solution when it comes to particularly tight tolerances. And they also create smooth component surfaces with exceptional surface finish.
The advantages of cermet at a glance:
- High hardness and wear resistance
- High thermal shock and oxidation resistance
- Low density
- Low thermal conductivity
- Low susceptibility to diffusion and adhesion
- High temperature resistance (up to 1800°C)
