TCMT 16T304 AH725 — Turning indexable insert (PVD-coated carbide, 0.4 mm radius) by Tungaloy

The TCMT16T304 AH725 is an ISO-standard triangular indexable turning insert designed for external and internal turning, offering a universal, breakout-resistant grade suited to varied materials and demanding process-security requirements.

• TCMT16T304 ISO insert, 60° triangular geometry
• PVD-coated AH725 carbide for Stahl and rostfreier Stahl
• 0.4 mm corner radius with one-sided chipbreaker
• Central hole with cylindrical bore and 40°–60° countersink

Consistent cutting performance for mixed-material turning

The PVD-coated AH725 grade delivers a balance of wear resistance and edge stability tailored for frequent material changes and smaller toolholders. The coating reduces diffusion and adhesion at the cutting edge, so the insert maintains its geometry over longer cycles and supports stable chip formation, which in turn reduces cycle interruptions. For practitioners who require a predictable process, this grade provides a reliable compromise between toughness and hardness, improving part-to-part repeatability when machining Stahl and rostfreier Stahl.

Predictable fit and geometry for accurate results

Made to ISO dimensions, the insert’s 60° triangular geometry and defined form factor ensure compatibility with standard external holders when form, clearance, tolerance class, fastening, size and thickness match. The listed 7° clearance angle and 3.97 mm thickness contribute to predictable cutting engagement and mechanical support; because holder compatibility depends on these parameters, the insert can be integrated into existing tool systems with minimal adjustment. The ISO standardisation reduces setup uncertainty and supports consistent positioning, which is essential for tight-tolerance turning.

Secure clamping and controlled chipbreaking for surface quality

A central fastening design — a cylindrical hole with a one-sided countersink (40°–60°) — enables secure seating and reliable torque transfer to the holder, lowering the risk of micro-movement under load. Combined with the one-sided chipbreaker and 0.4 mm corner radius, the geometry favours controlled chip flow and improved finish on small radii features. This combination is particularly effective where short overhangs and higher spindle speeds are used, as the insert’s geometry dampens vibration and supports a steady cutting edge life, reducing rework and scrap rates.

Practical selection guidance for process security

The insert is optimised as a universal option for turning operations where machines face varying materials and stability requirements. As a universal, out-break resistant solution it is well suited for smaller tools and setups demanding high process security. Selection should match the chipbreaker and grade to the intended cut (roughing vs finishing) and the workpiece material; in many mixed-production environments, this insert reduces inventory complexity while maintaining machining reliability. For application advice and holder matching, Metav Werkzeuge’s technical specialists can support the selection of the correct chipbreaker and clamping system.

FAQ

What materials is the insert suitable for?
The TCMT16T304 AH725 insert is specified for machining Stahl and rostfreier Stahl, offering universal performance across common turning materials.

How does the AH725 grade affect tool life?
The AH725 PVD-coated carbide balances wear resistance and toughness, extending edge life under mixed-material production and supporting consistent cutting performance for the TCMT16T304.

What must be considered for holder compatibility?
Compatibility depends on matching form, clearance angle (7°), tolerance class, fastening, size (16) and thickness (3.97 mm); ensure the holder accepts ISO TCMT inserts to guarantee secure seating.

What advantage does the central hole design provide?
The central cylindrical hole with a one-sided countersink (40°–60°) enables secure clamping and consistent torque transfer, reducing insert movement and improving surface finish under load.

Is this insert suitable for small toolholders and high-process-security applications?
Yes — the universal, out-break resistant design of the AH725 grade makes this insert particularly useful for smaller tools and setups requiring high process security; TCMT16T304 offers stable chip control in such environments.
