TCMT110208-FM4 WSM20S indexable insert for drilling and turning — Tiger‑tec Silver, 7° relief (Walter Tools)

The TCMT110208-FM4 WSM20S is an indexable insert designed for demanding turning and bore-up applications, optimised for stainless steel and high-temperature alloys; its triangular 60° form and FM4 chipbreaker enable stable chip control in tough cutting conditions.

• Tiger‑tec Silver coated carbide
• Suitable for stainless steel and superalloys
• 7° relief for secure cutting
• Triangle 60° insert, 0.8 mm corner radius

Increased productivity on tough-to-machine materials

The coated-carbide grade WSM20S is engineered to improve productivity when working with challenging alloys. Thanks to the Tiger‑tec Silver coating and a geometry tailored for heat resistance, the insert promotes stable cutting edges and reduced wear when machining stainless steel and heat-resistant superalloys. This yields longer tool life and fewer index changes, which supports uninterrupted production cycles and lowers process costs.

Coating and chip control that reduce rework

A combination of Tiger‑tec Silver surface treatment and the FM4 chipbreaker focuses on predictable chip formation and thermal management at the cutting zone. Predictable chips lower the risk of built-up edge and surface damage, so finishing operations are less frequent. The insert’s design converts coating and geometry into tangible process benefits: improved surface quality and reduced hand‑finishing for machined components.

Geometry that enhances dimensional stability

The triangular 60° form with a 0.8 mm corner radius and a 7° relief angle offers a balance between edge strength and cutting access. The compact inscribed circle and precise edge preparation help maintain repeatable results in interrupted cuts and when entering or exiting a bore. This geometry supports consistent part tolerances and contributes to reproducible machining cycles in batch production.

Application scope and process compatibility

Rated for ISO groups M and S, the insert covers stainless steel and high‑temperature alloys, making it suitable for sectors that demand heat‑resistant performance and robust edge control. The designation and tolerance class M indicate suitability for materials prone to workhardening and thermal strain. Integration into standard toolholders for drilling and turning is straightforward, enabling rapid deployment in existing setups without extensive tooling changes.
