TNMG 160412 T9225 Tungaloy turning insert — CVD-coated carbide, 60° triangle

A TNMG160412 T9225 Tungaloy insert engineered for robust medium-to-heavy steel turning with standard ISO compatibility

• CVD-coated carbide for extended tool life
• Robust T9225 grade for variable cutting
• 60° triangular form for secure clamping
• ISO compatibility simplifies holder selection

Reliable cutting performance for variable engagement

The T9225 grade is a CVD-coated carbide formulation developed for consistent results in medium-to-heavy steel turning when cutting conditions vary or when intermittent engagement occurs. The CVD coating increases wear resistance and helps maintain a stable cutting edge under elevated temperatures, translating into longer edge life and fewer tool changes. For production environments where process stability and predictable tool life matter, the coated carbide combination reduces unplanned downtime and supports steady component throughput.

Seamless integration with ISO turning systems

Designed to ISO geometry, the insert’s triangular 60° form and cylindrical hole ensure compatibility with a wide range of standard turning toolholders. Important mounting characteristics such as form, clearance angle (0°), tolerance class, fastening method, size (16 mm) and thickness (4.76 mm) determine holder fit; these parameters are matched by the TNMG160412 format. The 1.2 mm corner radius offers a balance between strength and finish, while the double-sided layout allows indexing for multiple cutting edges. Clear system planning — selecting the correct holder, shim and clamping set — simplifies changeover and preserves clamping integrity.

Practical benefits for production and process security

In daily workshop use, this insert delivers predictable chip formation and reliable surface quality when paired with an appropriate double-sided chipbreaker and cutting data tuned to the workpiece and machine stability. The universal nature of the grade and the ISO standard form make it suitable for both external and internal turning tasks where robustness is required. A system-oriented approach — insert, matching holder, underlay or clamping set and spare screws — minimises machine downtime and supports consistent production rates. For manufacturing teams seeking efficiency and repeatability, the insert’s combination of toughness and wear resistance is a sound investment in process security.

FAQ

Which materials is this insert suitable for?
The TNMG160412 T9225 insert from Tungaloy is primarily specified for medium-to-heavy steel turning where toughness and wear resistance are required, particularly under changing engagement or intermittent cuts.

What advantages does the T9225 grade provide?
T9225 is a robust, universal CVD-coated carbide grade that offers enhanced edge stability and wear resistance, making it suitable for varying cutting conditions and helping to extend edge life compared with uncoated grades.

How is the insert mounted in the toolholder?
Mounting relies on ISO-compatible geometry: the triangular TNMG form, cylindrical hole and standard thickness (4.76 mm) enable secure clamping in standard TNMG holders, using the correct shim or clamping set and fastening screws.

Can the insert be indexed or reused?
Yes — the TNMG160412 design is double-sided and indexable, allowing the operator to rotate or flip the insert to new cutting edges until all available edges are used, optimising cost per edge.

Which chipbreaker and cutting conditions should be chosen?
Select the chipbreaker and cutting data according to workpiece material, depth of cut and machine/tool stability; the TNMG160412 is designed to be paired with an appropriate double-sided chipbreaker and cutting parameters optimised for steel turning.
