TNMG 160404 AH725 TNMG160404 turning insert by Tungaloy — PVD-coated carbide, 60° triangle

TNMG160404 AH725 is an ISO-format turning insert engineered for external and internal turning, offering a universal, fracture-resistant grade for steel and stainless steel applications.

• 60° triangular geometry for stable cutting
• PVD-coated carbide AH725 for steel and stainless steel
• Double-sided chipbreaker for versatile machining
• Cylindrical-hole mounting with 0.4 mm corner radius

High process security through material and coating

The combination of a PVD-coated carbide substrate and the AH725 grade provides reliable performance in varied turning tasks. The coating increases wear resistance and thermal stability, which extends tool life in interrupted and continuous cuts. For operations on steel and stainless steel, the chosen grade promotes stable chip formation, reducing the risk of edge chipping and unplanned downtime. This results in higher first-pass yield and predictable tool change intervals—advantages that are particularly relevant for production environments where process security and repeatability are priorities.

Versatile geometry that supports both external and internal turning

The 60° triangular geometry and the 0.4 mm corner radius create a balanced mix of strength and finish capability. The triangle shape offers three usable cutting edges per side, so the insert is cost-effective in indexable systems. The moderate corner radius improves durability on heavier cuts while still allowing a good surface finish on finishing passes. For shops machining a variety of components, the insert’s combination of geometry and small corner radius means fewer tool variants are required, streamlining tool stocking and set-up procedures.

Compatibility and secure clamping for consistent results

Compatibility with holders is determined by form, clearance angle, tolerance class, fixing method, size and thickness. This ISO-format insert, with its cylindrical hole and standard dimensions, fits most conventional external holders and boring bars designed for TNMG inserts. The double-sided chipbreaker aids chip control in both directions, lowering the likelihood of chip entanglement during long turning cycles. Proper selection of a matched holder and clamping set ensures repeatable positioning and consistent cutting performance across batches.

Practical benefits for workshop efficiency

Using an indexable insert of this specification reduces downtime related to tool regrinding and increases operational flexibility. Replacement is straightforward: when an edge is worn, indexing or replacing the insert restores cutting performance without retooling the machine. The PVD-coated carbide construction is well suited to mixed-production environments where small to medium-sized tools and high demands on process reliability are common. This contributes to predictable maintenance planning and supports leaner inventory management.
