“This is essentially a performance upgrade”, confirms Haider Arroum, Team Leader of Tool Sales at the Ettlingen factory. “The reason is that our customers have to machine increasingly harder materials, such as 42CrMo4 (900 – 1200 N/mm²), for example, and need a higher tool performance as a result. These new materials were seen as somewhat exotic in the past, while these days they are pretty widespread. We opted for this development to ensure that our stock tools offer more flexibility for our customers.”

Thanks to the new material and coating combination, the tool life can be significantly extended. It also facilitates higher cutting speeds in wet and dry machining without negatively-affecting tool life.
