Tools for hardened steels

In tool and die production in particular, hard machining is playing an increasingly important role by replacing time-consuming processes such as grinding and eroding. But in other industries too, components still need to be machined after hardening, which presents enormous challenges for drilling and milling tools. We have identified the needs of our customers and have created a highly specialised range of tools for all conceivable applications. These tools are the ideal solution for steel machining in the maximum hardness range and guarantee maximum time savings with their strong performance characteristics.

The professional tool for trochoidal rough machining in hardened material applications

The CircularLine – CCR – H is the latest development of our tried-and-tested trochoidal milling cutter from the CircularLine series and is the ideal tool for machining hardened materials. The ultra-fine grain substrate tailored specifically to hard machining, the latest Dragonskin coating technology, the optimised cutting edge geometry and a new chip breaker make the CircularLine – CCR – H the ultimate tool for hard milling operations up to 70 HRC.

The latest Dragonskin coating technology DPX62S features high hot hardness and oxidation resistance of up to 800 °C. The titanium aluminium nitride-based broadband coating has been specially developed for the machining of hardened steels and boasts an optimised coating and surface structure.

The perfectionist in finish machining

For many tool and die production companies, time-consuming eroding has been the only option to date for achieving high-quality surfaces on workpieces with a hardness exceeding 55 HRC. This is now a thing of the past, as we are offering the perfect alternative with the MonsterMill – HCR. The MonsterMill – HCR is ideal for finish machining and is the optimal tool for hardnesses up to 70 HRC. Its stable cutting edge geometry in combination with the polished cutting edge section ensure flawless component surfaces and optimum contour accuracy with long tool life.

The latest Dragonskin coating technology DPX62U features high hot hardness and oxidation resistance of up to 1150°C. The titanium aluminium nitride-based broadband coating has been specially developed for the machining of hardened steels and boasts an optimised coating and surface structure. The ultra-fine grain substrate combined with the coating enables economical hard machining up to 70 HRC.

The multitool for drilling, countersinking and threading

Eliminate the need for time-consuming erosion operations when producing a thread in a hardened component with the BGF – Type H circular thread milling cutter. Threads with a depth of up to 2xD can be produced using the through and blind hole thread multitool – and with maximum process security. The left-hand cutting tool not only saves considerable time that would be required for eroding, but also avoids additional costs. The BGF – Type H is therefore the economical, productive solution for thread production in hardened and difficult-to-machine materials.
