CNMU160812-D57T WSP45G milling insert — Tiger·tec Gold, Rhombus 80°, 0° negative rake, Walter Tools

A high-performance indexable milling insert designed for general-purpose milling in steels, stainless steels and heat-resistant alloys where consistent chip control and edge stability are essential

• Tiger·tec Gold PVD coating
• Rhombus 80° cutting geometry
• 0° negative rake for stable cutting
• Suitable for steel, stainless and superalloys

Optimised coating and grade for reliable edge life

The Tiger·tec Gold PVD coating paired with the WSP45G grade delivers a balance of toughness and wear resistance that reduces flank wear in interrupted and continuous milling. This coating technology supports stable cutting at elevated temperatures, meaning fewer unexpected tool replacements and more predictable production cycles. The combination is particularly advantageous where thermal load and adhesion risk are high, as the coated carbide substrate preserves the cutting edge and improves lifetime under varied cutting conditions.

Geometry that enhances milling efficiency and chip control

The Rhombus 80° shape and the 1.2 mm corner radius offer a robust cutting edge with improved strength for both slotting and face milling operations. The 0° negative rake contributes to a conservative cutting action that stabilises the cutting process, especially in roughing or when machining interrupted surfaces. As a result, machining runs benefit from reduced vibration and consistent surface finish, translating into lower scrap rates and a steadier process window.

Broad material capability for versatile applications

Designed for ISO groups P, M and S, this insert tackles unalloyed and alloyed steel, stainless steels and heat-resistant superalloys including titanium alloys. The grade’s toughness accommodates the difficult chip formation and heat generation typical of these materials, enabling safer machining of sticky or gummy steels as well as hard-to-cut high-temperature alloys. Using a single insert type across these groups simplifies tool inventory and improves shop-floor flexibility.

Predictable production through tolerance and design details

With a tolerance class M, an indexable plate thickness of 08 and the D57T chipbreaker, the insert offers dimensional consistency and controlled chip segmentation. These characteristics reduce the need for constant parameter adjustments and help maintain part quality batch after batch. The solid engineering behind the insert supports steady cycle times and contributes to overall process reliability, an essential factor in production planning and cost-efficiency.
