HDC machining has already proven its worth in multiple applications with nonhardened materials. And yet HDC machining is almost unknown in the field of mold making. With this in mind, FRAISA has developed two new types of tools that break into precisely this area and realize their enormous potential there. The HX and XSpeed-H are perfect additions to the HX family, which has been specifically designed for high-performance milling of high-hard steels. Optimal tool geometries developed specifically for machining hardened steels, combined with an extremely hard Duro-Si coating, guarantee not only a long service life, but also universal operating conditions with 100% HDC suitability.
HX-tools are designed to be very robust and they are optimized for high cutting rates. The four-edged tool is ideal for materials with a hardness of more than 50 HRC and develops its maximum performance in 2.5D and 3D machining. In HDC applications, the contact length of the cutting edges with the material is long. The orbital motion in the case of the HDC strategy guarantees consistent chip thickness and cutting forces, for which the HX is precisely designed. The result is exceptionally high machining rates and a long service life.
But the HX also masters HPC applications with flying colors, highlighting the universal character of this tool.
The HX is equipped with a highly precise corner radius. This makes the very strong and precise HX virtually ideal for finishing operations with very narrow tolerance bands and premium surfaces.
Shifting the focus from universality to a long tool life, this is where the XSpeed-H comes into its own. The new XSpeed-H has been developed especially for HDC and HSC milling. The high number of cutting edges – with up to eight teeth – guarantees silky smooth movement of the milling tool.
As a result, wear and tear is spread across eight cutting edges and the tools can enjoy a very long service life. XSpeed-H
milling tools enable feed rates to be doubled for both HSC and HDC milling. This is a very positive product feature that plays to the capabilities of today’s highly dynamic milling machines and reduces production costs long-term.
The benefits:
- Increased productivity through use of the HDC milling strategy now also with 2.5D and 3D machining of hardened steels
- Maximum component accuracy thanks to the tool’s extreme concentricity, shank accuracy, and resulting precision
- Services available FRAISA ToolCare® tool management system FRAISA ReTool® tool reconditioning, and FRAISA ReToolBlue tool recycling
- Good cost efficiency through faster milling processes with long tool life and fast feed and cutting rates
- Lower tool costs due to reduced wear thanks to Duro-Si hard coating and optimized wear distribution

The combination of highly innovative features results in a very powerful overall concept
Impressive thanks to wide range of applications
The two new milling cutters in the HX-family – the HX
and the XSpeed-H – complement each other excellently in all fields of machining hardened steels, especially in mold making. In particular, high-hard steels can be machined efficiently.
Long tool life
What’s more, the cutting edges suffer from very little wear and retain extremely good cutting performance even after a long time in use.
This very high resistance to wear means the lifespan of the tools can be extended considerably.
