Innovative carbide and cermet products at GrindTec

CERATIZIT presents solutions for precision-tool manufacturers and wood machining

CERATIZIT S. A., Mamer, Luxembourg (headquarters), February 2014

At GrindTec 2014 from March 19–22 in Augsburg, CERATIZIT will be presenting its latest developments in the field of carbide rods – rods with four coolant holes, milling cutter blanks combining two different grades of carbide and a new generation of cermet rods. And for wood machining, CERATIZIT will also be introducing self-sharpening saw teeth that can be soldered quickly.

CERATIZIT is expanding its product range with the launch of CTS20D – DualBlank, a milling cutter blank for universal use made of two different carbide grades. In the cutting zone, where performance is key, the blank consists of the high-performance grade CTS20D, while the shaft is made of TMG30, a resource-efficient recycled material. “We care a great deal about handling tungsten resources responsibly and sustainably,” says CERATIZIT product manager Christian Buschneg. “This is why our DualBlank technology is now available in conjunction with our CTS20D premium grade.”

New four-hole system delivers improved cooling

CERATIZIT has also boosted the efficiency of solid carbide drills by developing a range of rods offering four helical coolant holes. The two added holes allow more coolant to flow through the tool without any increase in pressure. And because the lubricant is distributed more evenly, the heat gradient at the cutting edge remains extremely low. So the material comes under significantly less stress, and is therefore much less likely to break.

Cermet: high resistance to heat, thermal shock and oxidation

CERATIZIT has now reintroduced cermet rods – and is the only rod manufacturer to do so. These are used primarily for reamers, but can also be found in milling applications. The reaming process generates high temperatures at the cutting edges. Our CTF28T grade is highly resistant to heat, thermal shock and oxidation. Cermet is exceptionally well suited to machining steel and cast iron. Here the tools, unlike those made of carbide, do not need to be coated. As a result, users enjoy extremely sharp cutting edges and a high level of surface quality.

Saw teeth: self-sharpening, quickly soldered and lightweight

CERATIZIT presents two innovative new products for wood machining:

Thanks to a groundbreaking layer structure, saw teeth made with CTDIA02 are self-sharpening. The result is a tool life of up to 250 kilometers, and tools that deliver an extremely high-quality finish throughout their useful life.

The main feature of the new 60000 series of saw teeth is a tooth radius that optimizes heat conduction. This makes the teeth quick to solder, thereby creating a uniform structure between the carbide and the main body.  And the redesigned shape also makes the tooth more lightweight.

Stop by and see us!

Our carbide experts will be available to talk to you throughout GrindTec. You can find us in Hall 5/Booth 5137.

We look forward to seeing you!

Lecture: How suitable is carbide for grinding?

There are various factors that determine whether or not a cutting material lends itself well to grinding: grinding force, the cutting performance required, the temperature of the workpiece during cutting, wear and tear on the grinding disc and the desired surface quality of the groove. Johannes Mayr, a CERATIZIT development engineer, will deliver a lecture on this topic at GrindTec, describing the diverse properties of carbide and explaining how they impact on grinding performance.

The lecture is entitled “Carbide: an examination and evaluation of its suitability for grinding”, and will take place at 2 p.m. in Hall 5 on Saturday March 22, 2014.

CERATIZIT passion and pioneering spirit for carbides

For over 95 years, CERATIZIT has been a pioneer developing exceptional hard material products for cutting tools and wear protection. The privately owned company, based in Mamer, Luxembourg, develops and manufactures highly specialised carbide cutting tools, inserts and rods made of hard materials as well as wear parts. The CERATIZIT Group is the market leader in several wear part application areas, and successfully develops new types of carbide, cermet and ceramic grades which are used for instance in the wood and stone working industry.


With over 9,000 employees at 34 production sites and a sales network of over 70 branch offices, CERATIZIT is a global player in the carbide industry. As a leader in materials technology, CERATIZIT continuously invests in research and development and holds over 1,000 patents. Innovative carbide solutions from CERATIZIT are used in mechanical engineering and tool construction and many other industries including the automotive, aerospace, oil and medical sectors.


The internationally active CERATIZIT Group unites the four competence brands Cutting Solutions by CERATIZIT, Hard Material Solutions by CERATIZIT, Tool Solutions by CERATIZIT and Toolmaker Solutions by CERATIZIT. The carbide expert also includes the subsidiaries WNT and CB-CERATIZIT, as well as the tool manufacturers Günther Wirth, PROMAX Tools, Klenk, Cobra Carbide India, Becker Diamantwerkzeuge, Best Carbide Cutting Tools and KOMET GROUP.

  • Rods with four coolant holes allow more coolant to flow through the tool without any increase in pressure.

  • Cermet rods have high resistance to heat, thermal shock and oxidation.

  • CTS20D–DualBlank: two different carbide grades – high-performance CTS20D in the cutting zone and TMG30, a resource-efficient recycled material, for the shaft.
