TNMG 160408 T9215 triangular indexable insert for turning, CVD-coated carbide, double-sided chipbreaker — Tungaloy

The TNMG160408 T9215 is an ISO-indexable turning insert designed for medium steel machining, providing a balance of wear resistance and fracture toughness for continuous to slightly interrupted cuts.

• CVD-coated carbide for increased wear resistance
• Suitable for medium steel machining
• Double-sided chipbreaker for versatile cuts
• ISO TNMG 16 × 4.76 mm, 0° relief

Longer tool life through a wear-resistant grade

The insert's core advantage is the T9215 CVD-coated carbide grade, which delivers a measurable improvement in wear resistance while maintaining edge toughness. For medium-steel turning operations this means fewer indexings and longer effective tool life under continuous and lightly interrupted cutting conditions. The material combination reduces flank wear progression and supports consistent component quality, which in turn lowers tooling-related downtime and contributes to predictable production cycles.

ISO conformity and geometry for quick holder compatibility

Built to ISO standards, the triangular geometry with a 60° included angle and a 16 mm inscribed circle gives a repeatable, compact cutting edge suitable for a wide range of external and internal turning tasks. The insert thickness of 4.76 mm, corner radius 0.8 mm, 0° relief angle and the cylindrical locating hole ensure dimensional compatibility with standard external holders and boring bars. The double-sided chipbreaker provides two usable cutting edges per side, making the insert economical in inventory management and straightforward to replace during shifts, provided the holder matches form, clearance angle, tolerance class, fastening and size.

Practical machining benefits and selection guidance

For stable chip control and reliable surface finish on medium steels, select the chipbreaker and grade according to workpiece material, machining type and assembly rigidity. The grade is optimised for productive turning where consistent edge integrity is required; it performs well in finishing and medium-depth roughing when machine setup is rigid and coolant application is appropriate. When specifying tooling, pair the insert with a holder that matches the ISO form and ensures correct rake and clearance; this preserves the insert's wear performance and maintains repeatable results across production batches.

FAQ

What materials is this insert suitable for?
The TNMG160408 T9215 insert is specified for medium steel machining and offers a balance of wear resistance and toughness suited to continuous and slightly interrupted turning operations.

How many cutting edges are available per insert?
Thanks to the double-sided chipbreaker and triangular form, the insert provides multiple usable edges, which improves cost-efficiency in machining cycles.

Which holder characteristics determine compatibility?
Compatibility depends on holder form, clearance (free) angle, tolerance class, fastening method, size and thickness; the insert is ISO-conformant for easy matching with standard holders.

What benefits does the T9215 grade deliver on the shop floor?
The T9215 CVD-coated grade extends tool life through improved wear resistance while maintaining edge strength, supporting higher productivity and consistent surface finishes.

Is this insert suitable for interrupted cuts?
The grade and geometry are designed for continuous to light interrupted cuts; for heavy interruptions a different geometry or tougher grade should be considered.
