SPMT120408-D51 WSP45G milling indexable insert – Tiger·tec Gold, 11° clearance (Walter Tools)

The SPMT120408-D51 WSP45G is a square milling indexable insert designed for versatile milling of steel, stainless steel and heat-resistant alloys, suited to industrial metalcutting applications.

• Tiger·tec Gold PVD-coated carbide
• 11° relief angle for reduced rubbing
• 0.8 mm corner radius for edge strength
• Square 90° form for robust milling

High-performance edge geometry for reliable cycle times

The combination of Tiger·tec Gold PVD technology and the WSP45G grade produces a coated carbide substrate optimised for milling tasks where edge stability and consistent wear behaviour matter. The coating reduces adhesive wear and supports a reproducible cutting edge, which translates into fewer tool changes and improved machining uptime. The deliberately chosen 11° relief angle minimises flank contact at heavy chip loads, lowering friction and heat transfer to the cutting edge. This results in reliable cycle times and predictable component quality when used in appropriate tool holders.

Broad material capability with stable chip control

This insert is graded for the ISO material groups P / M / S—that is, steel, stainless steel and superalloys/titanium—which makes it a flexible choice for mixed production shops and jobbing environments. The 0.8 mm corner radius balances edge strength with the ability to produce a consistent surface finish; a larger radius supports interrupted cuts and higher engagement, while still permitting fine finishing with suitable parameter adjustments. The built-in chipforming geometry ensures stable chip evacuation under typical milling feeds, reducing the risk of built-up edge and rework.

System compatibility and handling that supports productivity

Presented as a square 90° indexable plate (designation SPMT120408-D51), the insert fits common indexable milling systems and simplifies inventory management through a standard form factor. The D51 chipbreaker and tolerance class M ensure reproducible mounting and cutting behaviour, supporting process stability in serial production. The compact dimensions and clear grade designation facilitate fast tool selection and predictable lifetime planning, helping manufacturing engineers to specify the insert for recurring programmes and to maintain throughput without frequent adjustments.

FAQ

What materials is this insert suitable for?
The SPMT120408-D51 WSP45G is suitable for ISO groups P, M and S—namely steel, stainless steel and heat-resistant superalloys/titanium—due to the WSP45G grade and Tiger·tec Gold coating.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm corner radius increases edge robustness, improving resistance to chipping and enabling better surface finish in many milling operations when using the correct feeds and speeds.

Which chipbreaker is integrated and what is its benefit?
The D51 chipbreaker is specified for this plate; it supports controlled chip formation and evacuation, which reduces the risk of built-up edge and improves process reliability in continuous milling.

Is this insert compatible with standard toolholders?
The square 90° form and standard SPMT designation make the insert compatible with common indexable face and shoulder milling toolholders designed for SPMT plates.

How does Tiger·tec Gold improve tool life?
Tiger·tec Gold PVD coating enhances wear resistance and thermal stability of the cutting edge, providing more uniform wear patterns and longer useful life under mixed-production conditions.
