TNMG 160404 AT9530 TNMG ISO-160404 AT9530 turning insert by Tungaloy — coated cermet for finishing and light machining

The TNMG160404 AT9530 is a coated cermet ISO turning insert designed for finishing and light turning of steel; it is triangular, double-sided and supplied with a cylindrical hole for secure clamping

• Cermet coating AT9530 for superior surface finish
• 0.4 mm corner radius for precise finishes
• Double-sided chipbreaker for flexible use
• Cylindrical hole, compatible with ISO holders

Achieve consistent high-quality surface finishes with a cermet cutting edge

The coated cermet grade AT9530 is developed for finishing and light machining of steel where surface quality and uniform wear behaviour are decisive. Cermet combines ceramic and metallic properties to offer a harder cutting edge than conventional carbides, which reduces built-up edge in finishing cuts and helps maintain dimensional stability across production runs. The insert’s 0.4 mm corner radius and 60° geometry support fine profiles and tight tolerances while the double-sided design extends effective tool life, making the component suitable where repeatable, high-grade finishes are required.

Simple integration into ISO tool systems reduces setup time

ISO conformity ensures quick interchangeability with standard turning holders: the triangular format, the specified cylindrical hole, and the standardised size simplify selection and replacement. Compatibility is determined by form, clearance angle, tolerance class and thickness; the insert’s 0° clearance geometry and 4.76 mm thickness match a wide range of external holders and boring bars. This standardisation minimises downtime during tool changes and eases tool inventory management for job shops and production environments that demand predictable, efficient changeovers.

Reliable chip control and steady wear for improved productivity

The double-sided chipbreaker layout provides dependable chip formation during finishing passes, lowering the risk of surface marks and interruptions. The AT9530 coating promotes uniform wear across the cutting edge, which reduces frequency of indexings and supports longer, predictable tool life in light turning operations. For pragmatic productivity gains, selecting an insert with targeted chip control and consistent degradation behaviour helps maintain cycle times and reduces rework — a rational investment for parts where finishing quality drives final acceptance.

Practical application advice and recommended uses

This insert is tailored for turning operations where fine surface finish and gentle material removal are priorities; typical uses include external and internal finishing passes on steel components. When choosing an insert grade and chipbreaker, match the AT9530’s finishing focus to the workpiece material and machine stability: stable setups and modest feed rates favour the best surface outcomes. Minimum recommended practices include verified clamping torque, correct holder geometry, and monitored wear progression to maintain consistent part quality. The triangular, ISO-compliant design and standard dimensions support flexible deployment across most turning fixtures.

FAQ

Is this insert suitable for finishing steel components?
The TNMG160404 AT9530 insert is specifically optimised for finishing and light machining of steel, with a cermet coating that promotes superior surface quality.

Can the insert be used in standard ISO holders?
Yes, the insert follows ISO dimensions and features a cylindrical hole and standard thickness, enabling compatibility with conventional ISO turning holders.

What advantages does the AT9530 cermet grade offer compared with carbide?
The AT9530 cermet grade offers a harder cutting edge and improved wear uniformity for finishing operations, which helps maintain surface integrity over longer runs.

How does the 0.4 mm corner radius affect machining results?
A 0.4 mm corner radius provides a balance between edge strength and fine finish, supporting precise profiles and reduced risk of visible tool marks during finishing passes.

Is the insert reversible and how many edges are usable?
The triangular TNMG format is double-sided; the insert can be indexed to present fresh cutting edges, extending the effective life before replacement is required.
