EXPK1 Series.
EXPERTS FOR THE MACHINING OF STEEL & CAST IRON

The steel and cast iron material group is a challenging one for milling tools to handle, not least because of the variety of alloys that can be used and all the different properties they have. On the one hand, the tools need to be able to withstand huge amounts of strain, for example due to the high tensile strength of steel (up to 1400 N/mm²) and the unequal structure of cast iron. Yet on the other hand, very soft alloys require geometries that are favourable for cutting in order to ensure that the material can be machined effectively.


Cutting Speed

Designed for extremely high speeds and a long tool life

PERFORMANCE

Submicron substrate with tried-and-tested hardness and improved fracture toughness for lasting performance in all steel and cast iron alloys

high process reliability

Geometries designed for high process reliability, tailored to factors such as the complex requirements in the field of toolmaking and mould making

ALPHAFERRO PLATIN X

High-performance coating specially designed for the requirements of machining steel and cast iron

Hofmann & Vratny - EXPK1 Series

THE NEW EXPK1 SERIES

The H&V EXPK1 Series has been developed specially with these requirements for cutting steel and cast iron in mind. Our wide range of products guarantees you the perfect tool for machining almost any alloy available on the market today, and can be used with a high degree of process reliability in practically every manufacturing process.

Hofmann & Vratny - EXPK1 Series

The EXPK1 Series in COMPARISON WITH THE COMPETITION

In a wide variety of machining scenarios, the performance of the EXPK1 series was tested in parallel with competitor tools up to the maximum service life.

Hofmann & Vratny - Alpha Ferro Platin X

ALPHA FERRO PLATIN X

High-performance coating specially designed for the requirements of machining steel and cast iron.The standard coatings for machining steel, such as TiAIN coatings, have become so well-established on the market thanks to their characteristically solid properties when used for universal machining. In order to achieve this level of suitability for universal use in all steel and cast iron alloys while improving even further on the performance of the TiSiN-Alpha coating we have been using until now, we have built our new AlphaFerro Platin X based on an allnew AlCrTiN concept.

Flexibility

Designed for wet and dry machining

stability

Maximum stability for coating and cutting edges

Surface quality

Improved surface quality during finishing

Optimised heat dissipation

Optimised heat dissipation thanks to improved chip disposal during dry machining

Absolute smoothness

Absolute smoothness for a reduced friction coefficient (0.4)
