TPMT 090204 AH725 Tungaloy – ISO triangular turning insert for external and internal turning

The TPMT090204 AH725 Tungaloy insert is an ISO-standard triangular turning insert designed for reliable external and internal turning, optimised for steel and stainless steels and suited to varying workpiece materials and compact tooling setups.

• PVD-coated carbide AH725
• Universal for steel and stainless steels
• 11° relief angle for secure cutting
• Triangular 60° insert with 0.4 mm nose radius

Optimised grade for consistent process security and chip control

The AH725 grade is a PVD-coated carbide developed for universal, break-resistant performance across steel and stainless steels, which means fewer grade changes when workpiece materials vary. Its microstructure and coating combination support stable chip formation and reduced chipping on smaller tool bodies, delivering measurable improvements in process reliability. For production environments where changeovers and mixed batches are common, the optimised grade helps reduce scrap and unplanned tool changes while maintaining consistent material removal rates.

Geometry tuned for surface quality and tool life

A 60° triangular form with a 0.4 mm nose radius balances edge strength and surface finish: the small radius supports fine finishes on turned parts while the triangle shape provides three indexable cutting edges for economical tool use. The 11° relief angle reduces flank contact and rubbing, lowering cutting temperatures and abrasion. Combined with a plate thickness of 2.38 mm, the geometry ensures stable seating in compatible holders and predictable wear behaviour, translating to longer edge life and fewer interruptions in the machining cycle.

Easy integration into ISO systems and economical operation

Designed to the ISO standard, the insert integrates with a wide range of standard external holders and boring bars, simplifying tool management and inventory. The version with a cylindrical hole and single-sided countersink (40°–60°) allows secure clamping and repeatable positioning, while the single-sided chipbreaker supports controllable swarf for turning tasks. Overall, the design and material combination emphasise reliable wear resistance and productive machining, offering a cost-effective solution for shops seeking dependable, high-utilisation tooling.

FAQ

What materials is this insert suitable for?
The TPMT090204 AH725 Tungaloy insert is formulated for machining steel and stainless steels, offering universal performance across varying batches and workpiece compositions.

How does the AH725 grade improve process reliability?
AH725 is a PVD-coated carbide grade that combines wear resistance and breakage tolerance to ensure stable chip formation and extended edge life during turning operations.

Which holders are compatible with this insert?
Compatibility depends on form, relief angle, tolerance class, clamping method, size and thickness; the ISO-standard designation facilitates matching with common triangular external holders and boring bars.

What is the significance of the 0.4 mm nose radius?
A 0.4 mm nose radius provides a balance between surface finish and edge robustness, enabling fine finishing while maintaining sufficient strength for interrupted cuts.

Is the insert indexable and cost-effective for production?
Yes; the triangular geometry provides multiple indexable edges and, combined with the universal AH725 grade, supports productive, economical machining with reduced tool change frequency.
