CNMG 190612 T9215 – Turning insert (ISO indexable) by Tungaloy

The CNMG190612 T9215 is an ISO-standard rhombic turning insert designed for efficient external and internal turning of medium-strength steel, combining a CVD-coated carbide grade with a double-sided chipbreaker for consistent machining performance

• CVD-coated carbide for high wear resistance
• ISO CNMG 80° rhombic geometry
• 1.2 mm corner radius for robust finishes
• Double-sided chipbreaker with cylindrical hole

High productivity through optimised cutting grade and coating

The CVD-coated carbide grade T9215 delivers a balance of high wear resistance and edge toughness, making it well suited to medium steel turning under continuous to lightly interrupted cuts. Specified as an ISO-compatible indexable insert, the design reduces changeover time and supports consistent cycle times in series production. Choosing a grade matched to the workpiece reduces flank wear and extends service life, which in turn lowers tooling costs per component while maintaining repeatable dimensional accuracy.

Geometry and clamping for precision and surface quality

An 80° rhombic geometry and a 1.2 mm corner radius promote form stability and favourable cutting forces for robust external and internal profiling. The 6.35 mm plate thickness and the cylindrical hole enable secure clamping, helping to prevent vibration and edge chipping at higher feeds. The double-sided chipbreaker offers two usable cutting edges per index, improving economy and allowing predictable surface finish and tool life. These geometric choices translate directly into improved part quality and fewer in-process rejects.

Practical integration into ISO tooling systems

The insert is supplied as part of a standard ISO indexable system and requires a matching external holder, support pad and fastening hardware for full assembly. Compatibility depends on form, relief angle, tolerance class, fixing method, size and thickness; selecting the appropriate holder and the correct chipbreaker for the material and stability is critical. Systematic selection reduces unplanned downtime and supports lean machining workflows. If process conditions are variable, the T9215 grade provides a wide application window so setups remain robust even with moderate interruption of cut.

FAQ

What materials is this insert designed for?
The CNMG190612 T9215 insert from Tungaloy is optimised for medium-strength steel machining; the CVD-coated carbide grade T9215 combines wear resistance with toughness for productive steel turning.

How many usable cutting edges does the insert provide?
This rhombic CNMG insert is double-sided with a chipbreaker on both faces, offering multiple usable cutting edges and economic index changes for the Tungaloy CNMG190612 T9215 design.

Which holder features are required for correct clamping?
Secure clamping requires an ISO-compatible CNMG holder with the correct pad, screw and tolerance class; the insert’s cylindrical hole and 6.35 mm thickness demand matching holder seating and fastening.

Can the insert handle light interruptions in the cut?
Yes; the T9215 grade is specified for continuous to lightly interrupted cuts, providing a compromise between wear resistance and edge stability for varied production conditions.

What surface quality can be expected with a 1.2 mm corner radius?
A 1.2 mm radius supports good surface finish while maintaining edge strength, particularly on external turning and profiling where roundness and consistent finishes are required.
