Steel & Cast Iron

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.

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.

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.
