• ISO WNMG 080404 trigon insert
• 0.4 mm nose radius for fine contours
• Cylindrical hole, secure double-sided fixing
• Optimised for medium steel machining

Precision and productivity for medium steel turning

The CVD-coated carbide grade delivers a balance of wear resistance and fracture toughness, making the insert particularly well suited to medium-duty steel operations. Its double-sided chipbreaker and trigon geometry allow an economical use of both cutting edges, which increases effective tool life and reduces tool change frequency. The design supports continuous and slightly interrupted cuts, enabling stable cutting conditions that translate into consistent surface quality and repeatable cycle times on production turning centres.

Compatibility and installation for reliable operation

Delivered as an ISO WNMG insert, the part conforms to industry standards for shape, size and tolerance, which simplifies matching to standard external holders and boring bars. The cylindrical hole and specified thickness ensure secure clamping and correct seating in a compatible toolholder; compatibility is governed by form, clearance angle, tolerance class, fixing method, size and thickness. The insert's 0° clearance (facing the rake) and trigon profile are factors that influence seating and cutting geometry; correct holder selection ensures the optimal rake and lead angles for efficient chip formation and reduced vibration.

Application guidance and machining benefits

Using a CVD-coated grade such as T9215 in medium steel provides a clear cost-benefit: the coating enhances oxidation and abrasion resistance at elevated cutting temperatures, which supports higher cutting speeds and improved productivity. The 0.4 mm nose radius helps produce fine contours and consistent part finish while maintaining adequate strength at the cutting edge. For best results, select an appropriate holder, adjust feed and speed to match material and machining stability, and prefer continuous cuts or lightly interrupted conditions to exploit the grade's wear and toughness characteristics.

Durability, economy and process security

The combination of a robust substrate and CVD coating results in a tool that offers stable chip formation and predictable wear behaviour under standard turning loads. This leads to fewer unscheduled tool changes and lower overall tooling costs per part. The insert's geometry and chipbreaker contribute to controlled chip flow and reduced risk of built-up edge, supporting reliable production runs and improved throughput in serial machining environments.
