SNMG150616-RM5 WSM20S indexable turning insert – Tiger·tec Silver for stainless steel and superalloys (Walter Tools)

The SNMG150616-RM5 WSM20S is a square 90° indexable turning insert with Tiger·tec Silver coating, designed for heavy machining of stainless steel and heat‑resistant superalloys.

• Tiger·tec Silver coating for heat resistance
• WSM20S grade for stainless and superalloys
• RM5 chipbreaker for stable chip control
• Square 90° form with 1.6 mm corner radius

High‑temperature stability and material compatibility for secure productivity

The combination of the Tiger·tec Silver coating and the WSM20S carbide grade provides improved thermal stability and predictable wear behaviour when machining stainless steel and high‑temperature alloys. The coating technology helps dissipate heat from the cutting edge, which reduces the tendency for built‑up edge and supports a stable cutting edge life. For shops tackling persistent heat and work‑hardening challenges, this geometry and grade translate into fewer interventions and steadier component quality.

Consistent chip control and cutting reliability to reduce rework

The RM5 chipbreaker is tuned for reliable chip formation in tough, adhesive materials, enabling regular chip segmentation and safe evacuation. The negative 0° relief geometry and the square 90° insert form increase edge strength and support interrupted cuts or unstable clamping conditions. As a result, machining cycles become more predictable and the risk of surface defects or rework is reduced, improving overall process security on demanding turning operations.

Practical workshop benefits that improve uptime and handling

A 15 mm square insert with a 1.6 mm corner radius gives a balance between strength and dimensional accuracy: robust enough for heavier cuts while still allowing acceptable contouring and finish. The insert thickness and M tolerance class support repeatable indexing in standard toolholders. These features together mean fewer tool changes, simpler inventory management, and better utilisation of machine time in mixed‑batch production environments.

FAQ

What materials is this insert suited for?
The SNMG150616-RM5 WSM20S insert is intended for stainless steel (M) and heat‑resistant superalloys/titanium (S), exploiting the Tiger·tec Silver coating and the WSM20S grade for improved edge stability.

How does the RM5 chipbreaker affect machining?
The RM5 chipbreaker promotes predictable chip segmentation in adhesive and work‑hardening materials, improving evacuation and reducing the risk of entanglement during turning with the SNMG150616-RM5 WSM20S insert.

Which toolholders are compatible with the SNMG150616-RM5 insert?
Standard toolholders for SNMG inserts that accept 15 mm square, 90° geometry and M tolerance class are compatible; the negative geometry requires holders rated for robust indexable inserts.

Is this insert suitable for interrupted cuts?
Yes, the square 90° form, 1.6 mm corner radius and negative 0° relief combine to provide enhanced edge strength suitable for interrupted and heavy cutting conditions.

Can this insert improve surface finish on stainless parts?
When used with correct feeds and speeds, the thermal stability of Tiger·tec Silver and the WSM20S grade contribute to consistent cutting action and a reduction of built‑up edge, which helps achieve improved surface quality.
