TNMG160404 AH725 Tungaloy turning insert — PVD-coated carbide, 60° triangle

TNMG160404 AH725 Tungaloy turning insert offers an ISO‑standard triangular geometry designed for general turning applications where process security and material versatility are required

• ISO TNMG 160404 geometry, 60° triangle
• PVD-coated AH725 carbide grade
• Double-sided insert with chipbreaker
• Compatible with standard ISO turning holders

Consistent process security for turning operations

The insert delivers steady cutting performance thanks to the PVD AH725 coating applied to a tough carbide substrate. This combination is formulated as a universal, fracture‑resistant grade that stabilises the cutting edge across varying conditions, which reduces unplanned tool changes and supports predictable cycle times. For machining operations that demand reproducible results, the coated grade improves edge life and contributes directly to higher output consistency.

Broad material capability reduces tooling complexity

Optimised for machining steel and stainless steel, the cutting grade provides broad applicability so fewer tool variants are required across mixed batches. The double‑sided design with an integrated chipbreaker enables economical use of each insert, and the universal character of the grade makes it suitable where workpiece materials vary. The result is simplified inventory, fewer changeovers and an overall reduction in process complexity.

Secure mounting and geometry for repeatable accuracy

The triangular ISO form (TNMG) with a 60° included angle, an inscribed size of 16 and a nominal corner radius of 0.4 mm gives a clear geometric reference for fixture and holder compatibility. The insert’s thickness of 4.76 mm and the cylindrical hole for fastening ensure a stable clamping interface, which supports repeatable tool positioning and helps maintain surface finish quality across serial production. Clear geometric standards mean straightforward integration with common ISO turning holders.

Cost‑efficient handling and predictable maintenance

Because the insert is double‑sided and indexable, it offers multiple cutting corners per unit, lowering the cost per edge and extending service intervals. The PVD coating enhances wear resistance at cutting temperatures typical for turning steel and stainless steel, which contributes to longer tool life and reduced downtime for replacement. Together, these attributes support a measurable improvement in tooling economics and production uptime.

FAQ

Which materials are recommended for this insert?
The TNMG160404 AH725 insert from Tungaloy is specified for machining steel and stainless steel and is designed as a universal, fracture‑resistant grade for those materials.

Is the insert compatible with standard ISO turning holders?
Yes. The TNMG160404 geometry follows ISO standards and is compatible with holders that match the form, clearance angle, tolerance class, fastening and thickness requirements.

What does the AH725 grade contribute to performance?
AH725 is a PVD‑coated carbide grade developed to improve edge strength and process security; it supports reliable cutting when workpiece materials vary.

How is the insert clamped in the holder?
The insert is supplied with a cylindrical centre hole for fastening and is designed to sit on a matching seat with the correct clearance and tolerance to ensure repeatable positioning.

Can the insert be indexed to use multiple cutting edges?
Yes. The triangular, double‑sided format allows indexing to present fresh cutting corners, which extends the service life per insert.
