WNMG080404-TQ T9215 – Trigon turning insert, CVD-coated carbide by Tungaloy

The WNMG080404-TQ T9215 is a trigon ISO turning insert engineered for external and internal turning of medium-strength steels, providing a balance of wear resistance and fracture toughness for high-productivity machining.

• CVD-coated carbide grade T9215 for medium steel
• Trigon (WNMG) form with 80° cutting geometry
• 0.4 mm corner radius for accurate edge control
• Cylindrical hole for secure clamping and repeatability

Maximised productivity through optimised grade and coating

The CVD-coated carbide T9215 is designed for the demands of continuous to lightly interrupted turning of medium steel, combining enhanced wear resistance with sufficient fracture toughness. This leads to longer tool life and reduced insert changes, which in turn supports more stable cycle times and predictable production planning. The coating reduces flank wear and increases consistency across batches, so downtime for tool changes is minimised and the machining process remains productive.

Predictable set-up using ISO conformity and secure clamping

ISO standardisation ensures the insert’s dimensions and form match common holders and boring bars, with compatibility determined by form, clearance angle, tolerance class, fastening method, size and thickness. The 0° clearance and cylindrical hole offer a repeatable clamping interface, reducing set-up variance and enabling consistent part geometry. For workshops aiming to shorten changeover times, this predictability supports higher throughput and fewer alignment checks during regular production shifts.

Cutting geometry tuned for surface finish and chip control

The trigon shape with an 80° wedge provides a robust cutting edge that resists edge chipping under moderate loads, while the 0.4 mm corner radius delivers improved edge strength without sacrificing the ability to achieve tight tolerances. The TQ chipbreaker is matched to the grade and typical workpiece materials to produce controlled chips and stable cutting forces, leading to better surface quality and reduced risk of built-up edge. Together, these features help maintain dimensional accuracy and minimise rework.

Practical guidance for selection and system integration

The insert is intended to work within a system consisting of an ISO turning plate, a compatible external holder or boring bar, a shim/clamping set and replacement screws. Select the chipbreaker and grade according to workpiece material, cut type and machine stability: the T9215 grade is a first choice for medium-steel applications where a balance of productivity and tool life is required. For best results, ensure the seat is clean, the clamping torque matches the holder specification and the correct rake/clearance geometry is used; consult technical datasheets for cutting parameters and coolant practice.

FAQ

What materials is this insert suitable for? The T9215 grade insert is intended primarily for medium steels; the WNMG080404-TQ T9215 delivers a good balance of wear resistance and toughness for these materials.

How does the TQ chipbreaker affect machining? The TQ chipbreaker on this trigon insert promotes controlled chip formation and stable cutting forces, improving surface finish and reducing the risk of built-up edge during turning operations.

Which clamping systems are compatible with this insert? Compatibility is determined by form, clearance angle, tolerance class, fastening style, size and thickness; the cylindrical hole and ISO form ensure secure mounting in standard WNMG-compatible holders.

What does the 0.4 mm corner radius mean for precision work? A 0.4 mm corner radius increases edge strength while enabling acceptable dimensional control; it is a compromise between robustness and the ability to produce fine contours.

Is this insert suitable for interrupted cuts? Yes—the T9215 grade is designed for continuous to lightly interrupted cutting; for heavier interruption, consider application-specific grades or increased clamping rigidity.
