TIGER·TEC® GOLD IS PUSHING THE BOUNDARIES – NOW FOR DRILLING
The Walter PVD grade WSP45G opens up a new range of applications
With Tiger·tec® Gold, Walter established a milling grade (initially CVD) on the market that many users consider to be the benchmark due to its long tool life. Walter is now expanding the wide range of Tiger·tec® Gold applications to drilling for the first time with the addition of the new PVD grade WSP45G.
WSP45G is the only grade on the market thus far to come with an aluminium oxide (Al2O3) multilayer: Its high level of crystallisation makes it not only extremely wear-resistant, but also heat-resistant. This effectively protects the TiAlN layer below it from heat transfer and therefore from wear when processing ISO P materials. This is the case particularly whenever heat cannot be dissipated through chips – for example when processing ISO materials M and S with poor thermal conductivity. A gold-coloured top layer made from zirconium nitride (ZrN) makes wear detection easy so that every cutting edge is used.
The three indexable insert drills Walter has selected for use with the equally tough and wear-resistant Tiger·tec® Gold cutting tool materials cover a wide range of applications: The B321x.DF. is particularly suitable for small diameters from 10 to 18 mm; it effectively competes with the solid carbide drills here. The D3120 is considered to be particularly economic because is only requires one type of indexable insert, both on the outside and in the centre; these are universal requirements the WSP45G grade meets perfectly. As a specialist for use on lathes, the D3120 additionally benefits from the new grade as high wear forces are generated when turning with an X offset. Users requiring high precision when drilling should select the D4120 for diameters from 13.5 to 59 mm.

HIGHLY POSITIVE WITH FOUR CUTTING EDGES
New Walter MN3 geometry for cost-effective ISO N machining
Walter is launching the new MN3 geometry especially for the quickly growing potential of ISO N materials, for example aluminium. While it is highly positive it can be used on both sides and therefore combines a long tool life and high metal removal rates with greater cost-efficiency.
The polished rake face (for improved chip evacuation) and the extremely sharp cutting edge (for a softer cutting action) of the new geometry are particularly important factors for the insert’s good performance. The double-sided insert is a useful expansion of the existing Walter portfolio for ISO N machining with the positive geometries FN2 and MN2. Walter is launching the new indexable insert in two grades: As a cost-effective, uncoated and polished grade WN10 and in the grade WNN10, with a wear-resistant HIPIMS PVD coating, extremely smooth surface and optimised layer bonding.
MN3 is the first Walter geometry to have double the number of cutting edges while also being highly positive. The rake angle on the radius is 29 degrees. It can be used both for the medium machining of non-ferrous metals and ISO N alloys (for example aluminium, copper or brass alloys) and for the fine finishing of small components made from steel and stainless-steel materials or high-temperature alloys. Thanks to the highly positive cutting edge and chip nubs, users benefit from improved chip breaking – even when working with “lead-free materials” like CuZn21Si3P. The surface roughness was optimised, which allows for an increased tool life even when working with materials that have a tendency to stick (built-up edges). The negative basic shape with double the number of cutting edges increases productivity and cost-efficiency.

UNIVERSAL EXCELLENCE IN MILLING
Walter Xill·tec™ combines performance with wide applicability
With Xill·tec™, the solid carbide milling cutters in the MC230 Advance product range, Walter is presenting a new range of products: A new type of high-performance geometry with an asymmetrical helix (35°/38°) was combined with Walter’s own wear-resistant and high-performance grade WK40TF. The result is a tool family with high performance that also offers universal applicability for roughing and finishing.
The milling cutter experts have consolidated the developments of the past ten years in the Xill·tec™ range. The asymmetrical helix, the most important feature of the geometry, enables smooth, low-vibration operation: This is essential for long tool life and process reliability. Fractures are avoided and the high level of operational smoothness contributes to the soft cutting action of the Xill·tec™ milling cutter.
The solid carbide milling cutters are suitable for all ISO material groups (P, M, K, N and S) as well as all common milling operations, such as shoulder milling, ramping, (helical) plunging and full slotting (up to 1×D), while exhibiting a high-performance level. This is also true for innovative machining strategies such as dynamic milling. The comprehensive range of products also contributes to the universal applicability of the Xill·tec™: The milling cutters are available with and without corner radii, with centre cutting edge, reduced neck, protective chamfer, cylindrical and Weldon shank. The universal applicability and an outstanding price/performance ratio make the milling cutters an appealing option not just for sub-suppliers and channel partners, but also for users in a wide range of different sectors.
