TCMT 16T312 AH725 indexable turning insert by Tungaloy — triangular insert, 60° geometry, PVD-coated carbide

A TCMT 16T312 AH725 insert for turning, engineered for external and internal turning operations on steel and stainless steels, delivering stable chip formation and consistent process security.

• PVD-coated carbide AH725 grade
• Triangular 60° geometry for general turning
• 1.2 mm nose radius for robust edge strength
• Single-sided chipbreaker with hole and countersink

Consistent performance across changing workpieces

The AH725 grade is a PVD-coated carbide designed for universality and resistance to chipping, which leads to predictable tool life across a range of steels and stainless steels. In mixed-production environments where material batches vary, the combination of coating and substrate minimises unexpected fractures and reduces process interruptions. The result is a measurable improvement in machine uptime and a reduction in scrap caused by insert failure, supporting a more economical production flow.

ISO compatibility and straightforward tool integration

The insert conforms to ISO indexable-insert standards, meaning holder compatibility is dictated by insert form, clearance angle, tolerance class, fixing method, size and thickness. The triangular plate with a 60° included angle and 7° clearance provides a familiar geometry for a broad range of external holders and boring bars. The insert is supplied with a cylindrical hole plus a single-sided countersink (40°–60°), permitting secure clamping and simple replacement without additional modification to standard toolholders.

Predictable wear behaviour and efficiency benefits

Thanks to the PVD coating and the AH725 substrate properties, the cutting edge offers stable wear progression and reliable performance on smaller tools and demanding operations. The 1.2 mm nose radius balances edge strength and access to tighter profiles, enabling longer intervals between indexings and fewer unplanned changeovers. This predictability supports planning of maintenance cycles and contributes to lower total machining costs over time.

Application guidance for optimum results

The insert features a single-sided chipbreaker; match the chipbreaker and grade to the workpiece material and machining stability for best results. For external turning and light finishing passes on steels and stainless steels, the insert’s geometry and coating deliver a compromise of durability and surface quality. Selection of the matching holder and correct torque on the clamping screw are essential for process stability; compatibility is influenced by the insert’s thickness (3.97 mm) and size (16 mm), so verify holder fit before production runs.

FAQ

What materials is this insert suitable for?
The TCMT 16T312 AH725 insert is intended primarily for steel and stainless steels, where the AH725 grade provides fracture resistance and broad applicability.

What does the AH725 grade offer compared with other grades?
AH725 is a universal, fracture-resistant PVD-coated carbide grade designed for stable chip formation and reliable performance in mixed-material production.

How does the insert attach to the holder?
The insert uses a cylindrical hole with a single-sided countersink (40°–60°) for secure clamping in compatible ISO toolholders; compatibility depends on the holder form, size and tolerance class.

Is the 1.2 mm corner radius suitable for finishing?
A 1.2 mm nose radius provides a balance between edge strength and surface finish; it is suitable for many finishing and semi-finishing tasks while offering improved robustness.

Which insert dimensions are relevant when checking holder compatibility?
Key dimensions are plate size 16 mm, plate thickness 3.97 mm, included angle 60°, clearance angle 7°, and corner radius 1.2 mm — verify these against the intended holder.
