TNMG 160412 AH6235 Turning Insert — PVD-coated carbide for stainless-steel turning by Tungaloy

The TNMG160412 AH6235 is an ISO-standard triangular turning insert designed for external and internal turning, optimised for stainless-steel machining and for interrupted cuts where edge strength is critical.

• ISO-standard triangular insert, 60° geometry
• PVD-coated carbide grade AH6235 for stainless steel
• Double-sided insert with 1.2 mm corner radius
• Secure clamping via cylindrical hole for indexed holders

Greater productivity through tougher grade and coating

The PVD-coated AH6235 grade delivers a balance of toughness and wear resistance that is particularly effective when machining stainless-steel and when facing interrupted cuts or elevated breakout risk. By combining a tougher substrate with a ceramic-enhancing coating, the insert maintains a sharper cutting edge for longer periods, which translates into fewer tool changes and more uninterrupted spindle time. The double-sided design further extends service life by offering two cutting edges per index, improving overall cost efficiency without compromising surface quality.

Secure seating and consistent geometry for predictable results

The insert’s 60° geometry and 0° clearance combine to provide a repeatable cutting angle when seated in compatible clamping systems, while the cylindrical hole ensures positive location in many standard holders. These defined mechanical interfaces reduce micro-movement and vibration during cutting, which in turn stabilises chip formation and helps achieve consistent dimensional accuracy. The ISO conformity of the format simplifies replacement logistics and integration into existing tool inventories, supporting reliable process control in production environments.

Robust edge and application guidance for demanding turning tasks

A corner radius of 1.2 mm provides a stronger edge for heavy interrupted cuts and applications with a higher tendency to chip. For external and internal turning operations, select the matching chipbreaker and holder rigidity: the tougher AH6235 grade is recommended where intermittent engagement or poor material homogeneity is expected. Use stable clamping, appropriate feed rates and coolant strategies suited to stainless-steel machining to exploit the insert’s mechanical resilience while achieving acceptable surface finish and tool life.

Simplified inventory and compatibility benefits for workshop efficiency

As an ISO-format turning indexable insert, this item slots easily into standard tool management systems and reduces the need for bespoke solutions. The defined size (16), thickness (4.76 mm) and the presence of a central locating hole support rapid changeover and straightforward stock keeping. Maintaining a small range of proven insert grades such as this one enables predictable planning of maintenance intervals and purchase cycles, helping workshops to sustain throughput and reduce unexpected downtime.

FAQ

What materials is this insert intended for?
The TNMG160412 AH6235 insert is formulated for stainless-steel machining and performs well in interrupted cutting where a tougher grade reduces chipping.

Is this insert compatible with standard TNMG holders?
Yes, the ISO designation and the cylindrical hole mean the insert is compatible with ISO TNMG clamp-type holders that match the plate form, thickness and tolerance class.

How does the AH6235 grade affect tool life compared with general-purpose grades?
AH6235 is a tougher, PVD-coated carbide grade that improves resistance to fracturing in interrupted cuts, often resulting in longer edge life in demanding stainless-steel applications.

Can the insert be indexed to use multiple edges?
The item is double-sided, allowing indexing to the second cutting edge; this effectively doubles the number of available edges before replacement.

Which corner radius should be chosen for roughing vs finishing?
A 1.2 mm corner radius provides edge strength suited to heavier or interrupted cuts; for fine finishing, smaller radii are typically preferred where surface finish and lower cutting forces are the priority.
