TS16-ER20UNJ WMP22G — Indexable turning insert, Tiger·tec Gold coating, Walter Tools (for stainless steel)

The TS16-ER20UNJ WMP22G is an indexable turning insert engineered to provide consistent cutting performance for stainless steel in medium to robust machining conditions.

• Tiger·tec Gold coating for long tool life
• Optimised ER20UNJ chipbreaker for stainless steel
• Coated carbide WMP22G for stable cutting edges
• Designed for medium to heavy machining

Greater process reliability when machining stainless steel

The combination of Tiger·tec Gold technology and the WMP22G grade produces a coated carbide surface that resists edge wear and reduces the tendency for built-up edge when machining stainless steel. This results in more predictable tool behaviour and fewer unscheduled tool changes, which directly supports higher uptime in production environments. The insert’s geometry promotes controlled chip formation, helping to avoid clogging and thermal spikes that typically challenge stainless alloy machining.

Predictable edge life and improved chip control

The integrated ER20UNJ chipbreaker is tailored for stainless materials to enhance chip control and reduce cutting forces during interrupted cuts. By favouring continuous, manageable chips, the insert contributes to steadier surface quality and reduces the likelihood of rework. The coated indexable insert therefore supports consistent part tolerances and lowers overall process variance, offering a measurable productivity advantage for batch production and subcontract machining.

Practical guidance for shop-floor integration

The TS16-ER20UNJ WMP22G insert suits conventional lathe and turning operations where robust performance is required. As a coated carbide product, it benefits from appropriate coolant strategies and stable clamping to exploit its tool life potential; good fixture rigidity and correct axial engagement help maintain the stable cutting edge. For workshops with mixed stainless work, the grade’s balance between wear resistance and toughness simplifies tool allocation and reduces the need for frequent grade switching.

FAQ

What materials is this insert intended for?
The TS16-ER20UNJ WMP22G insert from Walter Tools is intended primarily for stainless steel, corresponding to ISO material group M.

How does the Tiger·tec Gold coating benefit production?
The Tiger·tec Gold coating on the WMP22G grade increases wear resistance while maintaining edge toughness, which supports longer intervals between indexings and steadier productivity.

What role does the ER20UNJ chipbreaker play?
The ER20UNJ chipbreaker improves chip formation and evacuation when machining stainless steel, reducing built-up edge and promoting consistent surface finish.

Is this insert suitable for heavy interrupted cuts?
The combination of WMP22G grade and the ER20UNJ geometry is designed for medium to robust conditions; however, machine rigidity and correct clamping are essential for demanding interrupted cutting operations.
