Walter Tools expands grooving rangeWalter Tiger.Tec Gold Grooving Inserts

Walter Tools is expanding its Tiger·tec Gold range with the introduction of the new WSM13G, WSM23G, WSM33G and WSM43G grades for grooving applications. The diversity of the new grades makes them suitable for universal use, everything from grooving and parting off to groove-turning — in virtually any material.

The multi-layer Tiger·tec Gold PVD coating of the inserts was specially developed for the main types of wear that occur when grooving, ad what makes them so special is the combined TiAlN and TiSiN multi-layer coating. This makes the layers of the grades very hard and resistant against both flank face wear and plastic deformation. This is complemented by a special post-treatment process which ensures smooth rake faces, less friction and improved toughness. Walter is offering the grades in four versions with different levels of hardness or toughness. The WSM33G universal grade is suitable for 80% of grooving applications in steel, stainless and heat-resistant alloys.

If the level of wear is too high, users can choose from two harder grades for ISO M, S and P materials. The WSM13G is suitable for finishing and medium machining with uninterrupted cutting whereas the new WSM23G is suitable for stable conditions, high-speed cutting and where oil is used as the cooling lubricant. For particularly heat-resistant materials such as Inconel 718, the WSM13G achieves maximum tool life in combination with 150-bar precision cooling. If a tougher grade is needed, the WSM43G is perfect for interrupted cutting, machining at low cutting speeds or unstable conditions.

Walter is offering the new grades for all its grooving systems. This availability extends to the single-edged SX insert with positive engagement and self-clamping system, the four-edged MX cutting inserts with tangential clamping and dowel pin location, as well as a double-edged DX18 with positive engagement in the insert seat from an insert width of 1mm. All three offer outstanding friction and wear protection characteristics and this is credited to the patent-pending TiSiN/TiAlN multi-layer coating and the excellent wear detection due to the gold-coloured TiSiN top layer.
