Cutting Inserts

Standard or special inserts: carbide, ceramic, PCD, CBN – integrated tools and inserts

With its great know-how in the design and manufacture of cutting inserts, whether they be standard or special, evatec-tools prepares its own carbide grades and masters their pressing, sintering, and CVD and PVD coating. We can provide cutting inserts in a variety of materials.

Carbide inserts

We offer you standard and special carbide inserts to suit your type of machining (turning, milling, drilling, etc) in applications ranging from finishing to heavy roughing, for a wide variety of materials: all types of steel, cast iron, super alloys, etc.

Inserts from
evatec-tools are made to the most suitable profiles, with chip breakers, to guarantee good chip control, good surface finish, low cutting forces. Combined with the right grade, these give an excellent service life.

Consult our
evatec-tools carbide grades guide in the carbex-evamet section:


Cubic polycrystallines – PCD or CBN – are second to only diamond among the hardest known materials. As compensation for being less hard than diamond, PCD and the CBN withstand high temperatures better.

CBN materials can be split into two categories depending on their CBN content:

  • greater than 75%
  • less than 75%.

In the first case, the CBN is distinguished by high toughness and thermal conductivity, therefore its use is oriented towards rough turning and finishing of treated steels and hard irons.

In the second case, high pressure resistance and lower thermal conductivity make it more suitable for cutting hard materials.

Cutting edge geometry is a major factor in the performance of CBN.

To optimise your machining performance, we provide PCD and CBN inserts in integrated carbide tools or brazed inserts in a wide range of geometries and edge treatments.


  • better impact resistance than ceramics
  • better wear resistance than carbides

These positive points enable an increase in cutting speeds, thereby reducing machining costs.   


  • treated steels greater than 45 HRC
  • HSS
  • sintered steel
  • super alloys (Stellite, Incoloy, etc.)
  • sprayed metals
  • grey cast iron
  • non-ferrous metals and alloys
  • aluminium, copper, brass, bronze, gold
  • glassfibre, polyester, laminates and epoxy glass mats, loaded resins, carbon, SMC, etc.
  • graphite, ceramics
  • sintered and pre-sintered tungsten carbide
  • natural wood and composites

In order to machine cast iron, special alloys, and treated steels, evatec-tools takes blank stock and makes ready-to-use ceramic inserts in various grades.

The evatec-tools group is able to determine which cutting-edge treatments are best suited to your material types and machining.

Preparation of the edge is a crucial characteristic in the performances of this type of product. Associated standard or special tool holders are also provided by the group.

White ceramic grade CYW15 (Al2O3 + ZrO2 ) intended for machining grey cast iron and malleable iron

Black ceramic grades CYB30 (Al2O3 + TiC) and CYB330 (Al2O3 + TiCN) dedicated to machining treated steels

Silicon nitride grade CYD300, CYD770 CYD880 (Si3N4), for the machining Ni-hard cast irons, refractory stainless steel, and super alloys

Reinforced ceramic (Whiskers): The ceramic is reinforced by a specific structure in which silicon carbide filaments (“whiskers”) are
added. The main field of application for this ceramic is in the machining of nickel based alloys and treated cast iron rolling mill cylinders. After a first use, evatec-tools grinds the worn ceramics inserts sent to it by its customers and converts them into inserts with a smaller inscribed circle in the aim of optimising their use (from SNGN or RNGN 2507 up to RCGX 06 06 T).
