Cutting tool materials with the Tiger-tec® technology brand are setting the standard in machining again and again, in terms of productivity and process stability. With the new cutting tool material Tiger-tec®Silver, the engineers at Walter have moved another great step closer to the ideal cutting tool material. Tiger-tec®Silver is ideal for dry and wet machining of steel and cast iron materials, and is at home in important key sectors: the automotive industry and rail vehicle manufacturing, power engineering, the aerospace industry, mechanical engineering and in mould and die making.

Extremely stable cutting edges for high level of process reliability Extremely smooth rake face for excellent tribochemical wear resistance Silver coloured flank face for extremely easy wear detection during use

UNiqUe ThroUghoUT The world With its globally unique CVD coating technology, the cutting tool material Tiger·tec®Silver is forging ahead into new dimensions. In day-to-day manufacturing, this means that increases in output of up to 100 % are possible in machining. Other features of Tiger·tec®Silver: – Enormous toughness and minimal formation of hairline cracks thanks to optimum residual strength – Greatly reduced tribochemical wear thanks to perfect, smooth rake faces – Not susceptible to thermal stress variations during wet and dry machining Completely new CVD coating technology: – Combines...

Tiger·tec®Silver The new technology HIGH lEVEl Of WEAR RESISTANCE A close-up view of the cutting edges shows it clearly: the new cutting tool material Tiger·tec®Silver can easily handle even the most difficult machining conditions thanks to its new, revolutionary coating. Hairline cracks, such as those that occur at high cutting speeds, with interrupted cuts and difficult cutting conditions in particular, are decisively reduced with Tiger·tec®Silver indexable inserts. In the example shown, heat treatable steel 42CrMo4 was milled twice, with the existing insert and with the new Tiger·tec®Silver....

PRODUCT PROPERTIES: Performance increase of up to 100 % - thanks to excellent wear behaviour combined with extreme toughness Excellent cutting and swarf evacuation behaviour - thanks to extremely smooth rake faces Resistant to deformation and oxidation wear - thanks to the new type of aluminium oxide coating High level of resistance to flank face wear - thanks to fine-grained, columnar, average temperature titanium carbonitride New dimension in the toughness to wear resistance ratio - thanks to the new type of coating technology BENEFITS FOR YOU: Low production costs - higher cutting speeds thanks...

Tiger·tec®Silver Applications and examples THE APPlICATION With the new Tiger·tec®Silver technology, there is also completely new surface treatment in addition to the special coating combination. Due to the optimal residual stresses, the toughness of the wear-resistant Tiger·tec®Silver cutting tool material increases exponentially. It is this combination of a high level of wear resistance and toughness that gives Tiger·tec®Silver superior machining performance.
