TNMG 160404 T9225 indexable insert for turning — Tungaloy (0.4 mm radius, 60°)

The TNMG160404 T9225 is an ISO-standard triangular indexable insert designed for external and internal turning in medium to heavy steel machining, offering a balance of toughness and wear resistance.

• CVD-coated carbide for robust performance
• Triangle 60° geometry for versatile turning
• 0.4 mm nose radius for fine profiling
• Double-sided insert with cylindrical hole

Stable cutting performance for interrupted and mixed cuts

The CVD-coated carbide grade T9225 is a universal, toughness-oriented specification that is engineered for medium to heavy steel machining. Its coating enhances thermal stability at the cutting edge while the substrate delivers resistance to chipping under variable engagement. As a result, shorter machining cycles and fewer indexings are achievable, which improves output consistency and reduces unplanned machine downtime. The combination of coating and substrate is selected to extend useful tool life while keeping costs per workpiece predictable.

Geometry and chip control that support repeatable surfaces

A 60° triangle form with a 0.4 mm nose radius provides a good compromise between profile detail and edge strength; this geometry is well suited to fine contours and general turning operations. The double-sided chipbreaker enables controlled chip formation across a range of depths of cut, reducing the need for frequent parameter adjustments. Compatibility with holders is determined by insert form, relief angle, tolerance class, fixing method, size and thickness, so the insert is intended to be used as part of a complete system consisting of an ISO insert, suitable external holder or boring bar, clamping pad and replacement screws.

Robust dimensions and handling for productive setups

With a plate thickness of 4.76 mm and a nominal size of 16, the insert provides sufficient stiffness for heavier cuts while still allowing economical indexing. The cylindrical locating hole simplifies positioning during clamping and supports stable seat contact. Thanks to its two usable cutting edges per side, inventory efficiency is increased and regrinding intervals are reduced. The coated surface also supports predictable wear patterns, which helps to plan tool-change intervals and maintain surface-quality targets over production runs.

Practical selection and integration advice

When choosing the correct grade and chipbreaker, match the T9225 grade to steels and mixed-operation conditions that require extra toughness, particularly where interrupted cutting or varying engagement occurs. For finishing or high-speed applications, select lighter chipformers and review the toolholder geometry to maintain required free clearance. The system approach—insert, holder, clamp and fasteners—ensures repeatable seating and torque behaviour; documentation of holder form and clamp type is recommended before procurement to verify fit.

FAQ

What materials is this insert best suited for? The TNMG160404 T9225 is optimised for medium to heavy steel machining where toughness is required, particularly for variable engagement and lightly interrupted cuts.

How does the T9225 coating affect tool life? The T9225 CVD coating increases thermal and abrasive resistance at the cutting edge, which helps to sustain cutting performance and extend the interval between indexings.

Can this insert be used for internal as well as external turning? Yes; the triangular indexable insert geometry and cylindrical locating hole make it suitable for both external and internal turning when paired with the correct holder or boring bar.

How many cutting edges are available per insert? The insert is double-sided with a triangular profile, providing multiple usable edges and improving inventory efficiency for production runs.

What should be checked for holder compatibility? Compatibility is determined by insert form, relief angle (0° in this case), tolerance class, fixing method, size and thickness; confirm holder seat dimensions and clamp style before assembly.
