The cutting tool material combines third-generation TiAlN with TiSiN to form a multi-layer coating with exceptional hardness and increased toughness. A special post-treatment reduces friction and ensures a smooth surface, thereby optimising chip removal and process reliability.
Furthermore, the gold top layer makes it easier for users to detect wear. Walter uses the new PVD coating on single-edged SX cutting inserts with positive engagement and a self-clamping system. It can also be applied to indexable inserts from the double-edged DX18 system, where a second prism ensures stability in the insert seat.
For manufacturers, the fact that this grade can be used with both systems delivers maximum versatility as it caters for all insert widths from 1.0mm to 10mm. Another advantage of the Tiger·tec Gold WSM33G grade is its adaptability, even under the most challenging of conditions. The universal grade can be used for 75% of all applications. This includes grooving and parting off, groove and copy turning or slot milling.
The system can undertake this on a range of materials from steel (ISO P30), stainless steels (ISO M30) or materials with difficult cutting properties (ISO S30). The universal application, long tool life and high resistance of the multi-layer coating against plastic deformation and flank face wear make the WSM33G grooving inserts an incredibly productive and reliable choice.
