TNMG 160412 T9215 Turning insert, Tungaloy — CVD‑coated carbide, 60° triangular

TNMG 160412 T9215 is an ISO‑standard triangular indexable insert designed for external and internal turning, combining wear resistance with impact strength for continuous to slightly interrupted cuts

• CVD‑coated carbide for high wear resistance
• Optimised for medium steel machining
• Triangular 16 mm plate, 60° geometry
• Double‑sided chipbreaker, 1.2 mm corner radius

Increased productivity through robust grade and coating

The T9215 grade, applied as a CVD‑coating on a carbide substrate, is engineered to balance high wear resistance with fracture resistance, making it well suited to sustained production runs. In practice, this means longer intervals between index changes and fewer unscheduled tool interventions, which directly improves throughput. The coating reduces flank wear under common cutting speeds and feeds used for medium steel; where intermittent cutting occurs, the combination of substrate toughness and coating stability helps prevent premature edge chipping.

Precise geometry for stable, repeatable turning results

The triangular geometry with a nominal 60° included angle and a 1.2 mm radius provides a compromise between edge strength and profile definition. The 0° clearance specification and a plate thickness of 4.76 mm ensure secure clamping and consistent tool overhang control, supporting repeatable surface finish quality in turning operations. As a double‑sided insert, the component offers two cutting edges per side, improving economy per index, while the triangular shape simplifies seat and screw compatibility with ISO‑conforming holders.

System compatibility and application optimisation

This insert fits into a standard ISO turning system composed of an appropriate external holder or boring bar, an underlay/clamping kit and replacement screws; correct pairing is determined by form, clearance angle, tolerance class, fixation method, size and thickness. The double‑sided chipbreaker configuration supports chip control during both continuous and slightly interrupted cuts; selection of chipbreaker style and the T9215 grade should follow the workpiece stability and machining strategy. For tailored recommendations regarding holder selection or cutting data for specific steel grades, technical consultation is advised to achieve optimum cycle times and surface integrity.

FAQ

What materials is this insert best suited for? This insert uses the T9215 CVD‑coated carbide grade and is primarily intended for machining medium steel, offering a balance of wear resistance and toughness for productive turning.

How many usable cutting edges does the insert provide? The triangular, double‑sided design supplies multiple cutting edges; the TNMG160412 format allows redistribution of wear by indexing the insert to fresh edges.

Is the insert compatible with standard ISO holders? Yes, the insert follows ISO geometry conventions and is compatible with ISO‑conforming external holders and boring bars when matched for form, tolerance class, fixation and thickness.

What are the key dimensional specs to check for holder matching? Check the inscribed circle (16 mm), plate thickness (4.76 mm), corner radius (1.2 mm) and the 60° geometry to ensure proper seating and clamping.

Which cutting conditions are recommended for interrupted cuts? For interrupted or unstable cuts, the T9215 grade and its tough substrate are recommended; choose a conservative feed and reduced speed, and consider a more robust chipbreaker depending on the interruption severity.
