Take advantage of the CVD-coated T9215 grade for outstanding wear and fracture resistance and stable turning at higher speeds and feeds; the result is extended tool life and more consistent component quality — order via Metav Werkzeuge or consult the technical team for cutting data and application advice. WNMG 080404 T9215 indexable turning insert for medium machining — Tungaloy The WNMG 080404 T9215 is an indexable turning insert engineered for medium machining of ISO P15 steels, combining a modern CVD-coated grade with a trigonal 80° geometry for reliable, productive metalcutting. CVD-coated grade T9215 for high wear resistance Excellent fracture resistance for stable turning Optimised for ISO P15 steels, mid-duty machining Double-sided chipbreaker, trigonal 80° form Increased productivity through a modern CVD grade The new CVD-coated T9215 substrate is designed for accelerated turning operations on ISO P15 steels. By allowing higher cutting speeds and increased feed rates, the insert raises throughput while maintaining component integrity. The coating technology reduces flank and crater wear, which translates into fewer indexings and lower tool-change frequency — a clear rational benefit for batch and continuous production environments. Technical buyers will appreciate the predictable performance that supports reliable cycle times and an improved cost-per-part ratio. Reliable performance and reduced risk of edge failure The insert’s grade delivers high fracture resistance and a surface treatment that suppresses crack initiation and limits crack propagation, so the cutting edge remains usable for longer under interrupted or unstable cuts. The result is stable machining even when facing moderate variances in material or machining conditions. For workshop planners, this means less scrap, fewer process interruptions and a steadier output quality — practical gains that support production planning and reduce rework. Geometry and mechanical advantages for consistent results Featuring an 80° trigonal form, a 0° relief angle and a 0.4 mm nose radius, the insert offers a versatile contact geometry suited to a wide range of turning tasks within medium machining. The double-sided chipbreaker improves chip control across typical feed ranges, while the insert’s 4.76 mm thickness and cylindrical locating hole ensure secure clamping and repeatable seating in standard toolholders. Together, these design elements produce improved surface finish and dimensional stability without complex adjustments. Application guidance and operational benefits Intended primarily for medium turning of ISO P15 steels, the insert performs best under moderate depth of cut with elevated speeds and feeds to exploit the CVD grade’s strengths. The combination of extended tool life and stable edge behaviour reduces tooling logistics and contributes to predictable maintenance intervals. For purchasers and process engineers, the practical advantage is clear: fewer tool changes, improved machine utilisation and a more economical production flow over time.

Technical data SKU: M702011230009 Designation: WNMG080404 Grade: T9215 Material: Carbide Form: Trigon (08) Core dimensions Nose radius: 0.4 mm Thickness: 4.76 mm Relief angle: 0° Insert angle: 80° Hole style: Cylindrical locating hole Special features CVD-coated grade T9215 for high wear resistance Double-sided chipbreaker for improved chip control Stable machining with suppressed crack growth Application: medium machining of ISO P15 steel Double-sided insert, trigonal geometry for multiple edges FAQ Is this insert suitable for finishing or medium turning? This insert is designed for medium machining applications; the CVD-coated T9215 grade performs best in medium turning of ISO P15 steels where higher speeds and feeds are desired. Which toolholders fit the WNMG 080404 form? The WNMG080404 geometry is compatible with standard 80° trigonal turning holders that accept 08-format inserts; secure clamping is supported by the cylindrical locating hole. How many usable cutting edges does the insert provide? The trigonal, double-sided design yields multiple indexed edges; the geometry provides several effective cutting corners per insert before disposal. What are the primary benefits of the T9215 grade? Tungaloy’s T9215 grade offers enhanced wear and fracture resistance thanks to a modern CVD surface, enabling extended tool life and consistent performance at increased cutting speeds. Can the insert handle interrupted cuts or unstable conditions? Yes — the suppressed crack growth and improved fracture resistance contribute to reliable performance in interrupted cuts and fluctuating machining conditions.
