TCMT 16T304 AH725 Turning insert – PVD-coated carbide, 0.4 mm radius, Tungaloy

The TCMT16T304 AH725 is an ISO-standard triangular turning insert designed for general-purpose external and internal turning, providing a balance of toughness and wear resistance for mixed-material production.

• PVD-coated carbide for wear resistance
• Universal AH725 grade for steel & stainless
• 60° triangular form for versatile turning
• 0.4 mm corner radius for fine finishing

Reliable cutting performance across steels and stainless steels

The combination of AH725 grade and a PVD-coated carbide substrate delivers consistent cutting behaviour under varied conditions. The coating increases surface hardness and reduces built-up edge, while the carbide core maintains fracture resistance; together these properties enhance process stability during batch runs and intermittent turning operations. The moderate 0.4 mm corner radius supports improved surface finish without sacrificing edge life, making this insert suitable for jobs where repeatable dimensional accuracy and a good finish are required.

Secure seating and ISO compatibility for quick tool changes

Designed as an ISO-format indexable insert, compatibility with holders depends on form, 7° clearance angle, tolerance class, fastening and the plate thickness of 3.97 mm. The centre cylindrical hole with a one-sided countersink (40°–60°) ensures positive seating and reliable clamp engagement in standard clamping systems. This construct simplifies insert changes and minimises spindle downtime; when paired with a matching external holder, the system provides repeatable positioning and fast indexability for high-mix production.

Efficient chip control and predictable process behaviour

The single-sided chipbreaker geometry supports controlled chip formation for typical turning operations, improving evacuation in through-turning and boring applications. The triangular 60° form offers flexibility in selecting cutting edges and angles for different cross sections, while the PVD surface treatment helps to extend edge life under moderate to high cutting speeds. For workshops seeking a pragmatic balance between tool life and cutting performance, this insert presents a productive option that reduces frequency of intervention and contributes to consistent cycle times.

FAQ

Which materials are suitable for this insert? The TCMT16T304 AH725 turning insert from Tungaloy is geared toward machining steel and stainless steels, with the AH725 grade offering balanced toughness and wear resistance for mixed-material production.

How does the insert secure to the holder? Secure seating is achieved via the cylindrical hole with a one-sided countersink (40°–60°); clamping into a compatible ISO holder provides repeatable positioning for the Tungaloy insert (SKU: 6865481-Tungaloy).

What benefit does the PVD coating provide? The PVD coating increases surface hardness and reduces adhesion of workpiece material, which improves wear resistance and helps maintain edge condition in longer cycles when using the AH725 carbide grade.

Is this insert suitable for finishing operations? Yes, the 0.4 mm corner radius supports finer surface finishes while the triangular geometry permits adaptive cutting strategies; the insert is appropriate for finishing within the capabilities of the machine and holder system.

How is chip control achieved with this geometry? Chip formation is assisted by the single-sided chipbreaker, which delivers controlled chip flow in typical turning tasks and reduces the risk of entanglement or unstable chip shapes.
