TNMG160404 AH6235 indexable turning insert — Tungaloy, PVD-coated carbide, 0.4 mm radius, 60°

A TNMG160404 AH6235 triangular ISO indexable insert designed for external and internal turning, optimised for stainless steel and applications with intermittent cuts

• TNMG160404 triangular ISO insert
• PVD-coated AH6235 grade for stainless steel
• 0.4 mm nose radius for stable finishes
• Double-sided chipbreaker with cylindrical hole

Consistent performance on stainless steel with AH6235

The combination of the AH6235 grade and a PVD-coated surface provides enhanced resistance to built-up edge and flank wear when machining stainless steel. The tougher substrate of this carbide grade is selected to withstand interrupted cuts and increased breakout risk, reducing the frequency of edge failures. For production environments, this means longer effective edge life and more predictable tool-change intervals, which supports continuous machining cycles and reduces unplanned downtime.

Geometry and mounting that support quick changeovers

The triangular ISO form with a 60° included angle and a 0.4 mm nose radius provides a balanced compromise between edge strength and surface finish. The insert is supplied with a cylindrical hole, enabling secure clamping in standard external holders and boring bars. The double-sided chipbreaker design allows reversible indexing of multiple cutting edges, lowering tooling costs per machined edge and simplifying inventory management. Compatibility with holders is governed by form, clearance angle, tolerance class, fastening and size — verify holder specification before assembly.

Process reliability and practical shop-floor benefits

Using this indexable insert in turning operations improves process stability through predictable chip control and robust cutting edges. The double-sided chipbreaker and the AH6235 coating reduce the tendency for catastrophic chipping in unstable feeds, making the insert suitable for mixed-batch work and components with interrupted profiles. For manufacturers aiming to optimise throughput and surface integrity, selecting the correct chipbreaker and grade for the workpiece geometry ensures efficient material removal and consistent part quality.

FAQ

What materials is this insert best suited for?
The TNMG160404 AH6235 Tungaloy indexable insert is formulated primarily for stainless steel and other tougher alloys; the AH6235 grade is chosen for interrupted cuts and scenarios with increased breakout risk.

What are the key geometric characteristics of the insert?
The insert features a triangular ISO geometry with a 60° included angle and a 0.4 mm nose radius; it also has a cylindrical hole for secure clamping and a double-sided chipbreaker for reliable chip control.

Is the cutting edge coated?
Yes — the AH6235 grade is PVD-coated on a carbide substrate, offering improved wear resistance and reduced built-up edge tendencies in demanding turning operations.

Can this insert be used for internal turning or boring?
Yes, the insert can be used for internal turning provided the chosen holder or boring bar matches the insert form, clearance angle and fastening dimensions; verify holder compatibility before use.

How many useful cutting edges does the insert offer?
As a double-sided triangular insert, the TNMG160404 normally provides multiple indexable edges; exact edge count depends on indexing practice and orientation, so consult the tooling instructions for optimal use.
