TNMG 160404 T9235 — turning insert by Tungaloy, CVD-coated carbide, 60° triangle

TNMG160404 T9235 indexable insert for turning, engineered for steel machining where toughness and chip control are required

• CVD-coated carbide grade T9235
• 60° triangular ISO geometry
• 0.4 mm corner radius for accuracy
• Double-sided chipbreaker with cylindrical hole

Robust grade for unstable and interrupted cutting

The insert uses a CVD-coated carbide substrate in grade T9235, a formulation developed for toughness rather than maximum speed. This makes the component particularly suitable when machining steel at reduced cutting speeds, or where the process is prone to vibration and intermittent cuts. The tough grade helps resist chipping at the cutting edge, which translates into fewer insert changes and more continuous production. In practical terms, this reduces downtime and helps maintain consistent part quality under challenging conditions.

ISO geometry and fit that simplify toolset selection

The ISO TNMG160404 triangular form with a 60° angle and a 0.4 mm corner radius follows standard dimensions, which simplifies selection of compatible holders. Compatibility with a turning toolholder is determined by form, relief angle, tolerance class, fastening and size; confirming these parameters ensures correct seating and secure clamping. The insert's cylindrical hole and double-sided layout enable straightforward indexing and positive clamping, permitting economical use of both cutting edges while maintaining positional repeatability.

Improved chip control and surface consistency

The double-sided chipbreaker is designed to manage chips effectively in a range of turning tasks, improving evacuation and reducing the risk of re-cutting. For external and internal turning, better chip control contributes to a more uniform surface finish and predictable tool life. The CVD coating offers wear resistance while the tough substrate absorbs intermittent impact—together these features help achieve a balance between stable chip control and edge life, especially in variable or semi-finished operations.

Practical system integration and economical operation

This indexable insert forms part of a complete turning system that includes the insert itself, the appropriate external holder or boring bar, a shim/clamp set and replacement screws. Using a double-sided, indexable geometry reduces tooling spend per cutting edge and simplifies inventory. For processors uncertain about holder compatibility or optimal cutting parameters, specifying the correct relief, tolerance and fastening type is essential to prevent assembly errors and ensure consistent machining results.
