TCMT06T102-FM4 WSM21 turning indexable insert — triangular 60°, 0.2 mm nose radius (Walter Tools)

The TCMT06T102-FM4 WSM21 is a triangular 60° coated carbide insert designed for turning and boring applications, optimised for stable chip formation in stainless steel and heat‑resistant superalloys

• Coated carbide grade WSM21 for tough materials
• Triangular 60° insert with 0.2 mm nose radius
• FM4 chipbreaker for reliable chip control
• 7° clearance angle for stable cutting performance

Higher process stability in stainless steel and superalloys

The WSM21 grade is a coated carbide formulation developed for demanding applications where material ductility and thermal build-up are common challenges. In stainless steel and similar alloys the tendency to form built-up edge is reduced by the combination of coating chemistry and microstructure, which leads to stable cutting edges and consistent tool life. The result is improved component repeatability and fewer unplanned stoppages, supporting higher overall productivity in series production and job-shop environments.

Geometry tuned for surface quality and dimensional control

A triangular 60° outline with a 0.2 mm nose radius provides a balance between edge strength and the capability to achieve fine surface finishes. The 7° clearance angle eases ingress and reduces flank contact, which helps to maintain tolerances and to avoid burr formation during finishing passes. These geometric choices translate into measurable benefits: reduced rework, predictable part accuracy and a clearer process window for stable machining of complex contours.

Controlled chips, fewer interruptions

The FM4 chipbreaker is designed for positive chip control when cutting high-strength and heat-resistant materials. By forming short, manageable chips and guiding their evacuation, the chipformer decreases the risk of entanglement and reduces cycle interruptions. This enhancement to the machining process supports longer uninterrupted runs and lowers the incidence of secondary operations to clear chips, contributing directly to improved throughput and lower unit costs.

Versatile application and practical support

Engineered for both turning and boring tasks, the TCMT06T102-FM4 WSM21 insert from Walter Tools is suitable where robust performance is required in stainless steel and heat‑resistant alloys. The design is adaptable to a variety of toolholders and cutting strategies, enabling use across turning centres and heavy‑duty lathes.
