WNMG080408 T6215 — WNMG indexable turning insert, CVD-coated carbide, for turning — Tungaloy

A WNMG080408-TM T6215 indexable insert designed for external and internal turning, optimised for stainless steels under stable to lightly interrupted conditions and compatible with standard ISO WNMG toolholders

• WNMG geometry, ISO-compliant insert
• CVD-coated carbide T6215 for wear resistance
• 0.8 mm corner radius for accurate profiles
• Cylindrical hole for secure clamping

Durable cutting performance for stainless steels

The CVD-coated T6215 grade provides a wear-resistant cutting edge that extends tool life when machining stainless steels. The coating system combines a tough substrate with a protective surface layer, which reduces abrasive wear and improves resistance to heat-induced edge softening. This results in more consistent tool life in both continuous and light interruption turning, contributing to predictable production cycles and reduced tool changes. The CVD-coated carbide formulation is explained for clarity: chemical vapour deposition applies hard layers that preserve edge geometry while maintaining substrate toughness.

Accurate geometry and reliable clamping for repeatable results

The insert's WNMG geometry and trigon profile ensure secure seating and repeatable positioning in compatible holders. With a 0.8 mm corner radius and 4.76 mm thickness, the design balances profile accuracy with sufficient edge strength for medium-duty turning. The cylindrical hole provides positive fastening and alignment, minimising micro-movements that can degrade surface finish. Compatibility with toolholders is determined by shape, relief angle, tolerance class, fastening method, size and thickness, which simplifies selection within an ISO-standard tooling system.

Practical system integration and application guidance

As part of the ISO turning insert family, the component fits into a system comprising an external holder or boring bar, a shim or clamp set and replacement screws, enabling rapid changeovers. The 0° relief angle suits many common turning set-ups where a neutral clearance is required, while the TM chipbreaker supports controllable chip formation for improved surface quality and machine uptime. For operations where machinability varies, choosing the correct chipbreaker and coating combination helps to maintain process stability and surface integrity. The insert is particularly recommended where consistent repeatability and predictable wear behaviour are priorities in serial production.
