TNMG160404 T9235 indexable turning insert — TNMG for turning, Tungaloy

A TNMG160404 T9235 indexable insert designed for external and internal turning of steel, offering stable chip control and reliable edge life under interrupted or unstable conditions.

• CVD-coated carbide for improved wear resistance
• Suitable for steel and interrupted cuts
• 0.4 mm nose radius for balanced finish and strength
• 60° triangular insert for versatile turning operations
• Double-sided chipbreaker for economical use

Stable cutting in interrupted and unstable conditions

The combination of a CVD coating with a tough carbide substrate provides resistance to abrasive wear while retaining edge integrity during shocks and interruptions. This makes the insert especially suitable for turning operations where feed and depth vary or the cut is interrupted by features on the workpiece. The T9235 grade is formulated for steel at moderate to lower cutting speeds, so the practical effect is fewer edge failures, longer useful life and increased process reliability — all factors that support predictable cycle times and reduced scrap rates.

Geometry that simplifies tool system integration

Designed as an ISO TNMG triangular insert with a 60° included angle and a 0° relief, the geometry matches a wide range of standard external holders and boring bars. The insert’s cylindrical hole and standard thickness of 4.76 mm allow repeatable clamping and positioning; compatibility is determined by form, relief angle, tolerance class, fastening, size and thickness. Using standardised holders and the correct clamping set ensures secure fixing and consistent cutting height, which in turn improves surface finish and repeatability across batches.

Economic advantages through usable edges and chip control

The double-sided design and defined chipbreaker deliver two usable edges per index, which increases cost-efficiency compared with single-use alternatives. The 0.4 mm nose radius strikes a balance between surface finish and edge strength: smaller radii improve detail and contour fidelity, while still providing sufficient edge stability for light interrupted cuts. Together, the double-sided chipbreaker and the robust grade reduce changeover frequency and machine downtime, supporting a measurable improvement in productivity for medium-duty turning tasks.

Practical application notes and selection guidance

When selecting an insert for a specific turning job, match the T9235 grade and the double-sided chipbreaker to the workpiece material and the expected cutting conditions. The grade suits a wide range of steels under less-than-ideal stability and at moderate cutting speeds; for harder or higher-speed applications, consider alternative grades. The ISO TNMG form is compatible with most triangular turning holders; ensure the holder accepts a 16 mm inscribed circle and the 4.76 mm thickness. For finishing operations, evaluate whether a smaller nose radius or alternative chip control geometry is preferable to achieve the target surface quality.

FAQ

What is the primary application for this insert?
The TNMG160404 T9235 Tungaloy insert is intended for external and internal turning operations on steel, especially under interrupted or unstable cutting conditions.

How does the T9235 grade perform compared with other grades?
T9235 is a CVD-coated, tough carbide grade optimised for steel at lower cutting speeds and offers good edge strength and wear resistance for interrupted cuts.

How many cutting edges are available per insert?
The triangular TNMG160404 insert is double-sided with multiple usable edges; the double-sided chipbreaker provides economical edge utilisation.

What does the 0.4 mm nose radius mean for surface finish?
A 0.4 mm nose radius offers a compromise between surface finish and edge strength: finer contour fidelity while maintaining sufficient robustness for medium-duty interrupted turning.

Is the insert compatible with standard ISO holders?
The TNMG160404 form is an ISO-standard geometry; compatibility requires matching the holder to the insert form, relief angle, tolerance class, fastening, size and thickness.
