CNMG 160612 T9205 indexable insert for turning by Tungaloy — rhombic 80° geometry, CVD-coated grade

CNMG160612 T9205 indexable insert designed for productive external and internal turning on steel under stable cutting conditions

• CNMG 160612 geometry for ISO turning
• CVD-coated carbide grade T9205 for steel
• 80° rhombic form with 1.2 mm corner radius
• Double-sided insert with cylindrical hole

Consistent productivity from a CVD-coated carbide grade

The CVD-coated cemented carbide grade T9205 is developed for productive machining of steel at elevated cutting speeds while maintaining wear resistance. The coating adds a hard, thermally stable surface that reduces flank wear and heat-related loss of edge life; this results in improved tool life and more predictable machining cycles. For operations where process stability and repeatable performance matter, the coated grade supports longer uninterrupted cutting times and reduces the frequency of tool changes, contributing to lower overall machining costs.

Precise geometry for reliable clamping and repeatability

The rhombic 80° shape with a 0° clearance and standard ISO dimensions ensures straightforward integration into common external holders and boring bars. Compatibility with a clamping system depends on form, clearance angle, tolerance class, fastening method, size and thickness; the ISO-conformant geometry simplifies selection of the correct holder. The insert’s cylindrical locating hole and standard thickness of 6.35 mm provide secure seating and repeatable indexability, helping to maintain concentricity and surface finish across multiple indexings.

Stable chip control and stronger cutting edge

Equipped with a double-sided chipbreaker, the insert offers balanced chip formation for many turning operations, enhancing evacuation and reducing the risk of built-up edge under recommended conditions. The 1.2 mm corner radius increases edge strength where contouring and moderate interrupted cuts occur, supporting better surface integrity and dimensional stability. In short cycle applications the combination of corner radius and chip control contributes to consistent component quality and lower scrap rates.

System-oriented handling and application guidance

The insert is part of an ISO indexable insert system that includes the mating external holder, shim/clamping set and replacement screws. When specifying for a shop, select the chipbreaker and grade that match the workpiece, machining strategy and machine rigidity; for this grade, stable setups and higher cutting speeds are ideal. The insert’s rhombic form and double-sided design mean two working edges per side, enabling economical use of the insert in serial production and straightforward inventory management.

FAQ

What materials is this insert intended for?
The Tungaloy CNMG160612 T9205 indexable insert is optimised for machining steel in stable cutting conditions; the CVD-coated cemented carbide grade offers wear resistance at higher cutting speeds.

How does one confirm holder compatibility for this ISO insert?
Compatibility is determined by the ISO geometry and by matching holder form, clearance angle, tolerance class, fastening method, size and thickness; the CNMG160612 designation helps to select the correct external holder or boring bar.

What advantages does the T9205 grade provide compared with uncoated grades?
T9205’s CVD-coated surface increases thermal and abrasive resistance versus uncoated carbide, yielding longer edge life and more consistent performance when turning steel at elevated speeds.

How many usable cutting edges are available per insert?
Due to the double-sided configuration and the rhombic form, the insert can be indexed multiple times; the CNMG160612 design provides economical reuse of cutting edges for serial production.

Is the insert suitable for internal as well as external turning?
Yes — the ISO CNMG geometry and the cylindrical locating hole allow use in suitable external holders and boring bars for both external and internal turning applications.
