TPMT090204 AH725 turning insert for turning — Tungaloy

The TPMT090204 AH725 is an ISO-indexable triangular turning insert designed for external and internal turning, offering a fracture-resistant grade and engineered geometry for dependable performance in steel and stainless steels.

• PVD-coated carbide AH725
• Triangular insert with 60° cutting angle
• 0.4 mm corner radius for versatile turning
• One-sided chipbreaker, countersunk hole

Consistent process security through material and coating

The AH725 grade combines a PVD-coated surface with a tough carbide substrate to reduce micro-chipping and extend edge life under varying conditions. As a universal, fracture-resistant grade, AH725 is optimised for steel and stainless steels where alternating workpiece materials or interrupted cuts demand steady performance. The coating enhances heat resistance and wear behaviour, which translates into fewer index changes and a more predictable production rhythm — a direct contribution to reduced machine downtime and improved overall productivity.

Geometry engineered for precise, repeatable cuts

The triangular ISO-indexable form provides a 60° included angle that balances strength and accessibility in external and internal turning. The 0.4 mm corner radius supports a mix of finishing and medium-cut operations, contributing to improved surface integrity without sacrificing tool life. A relief angle of 11° and a plate thickness of 2.38 mm ensure secure clamping and stable cutting conditions when the correct holder is selected. The one-sided chipbreaker is matched to common steel turning tasks to promote controlled chip flow and minimise re-cutting of chips, thereby protecting the cutting edge and workpiece finish.

Practical system integration and holder compatibility

This ISO insert fits into established indexable-turning systems; compatibility with a toolholder is governed by shape, clearance angle, tolerance class, clamping method, size and thickness. The TPMT090204 features a cylindrical hole with a one-sided countersink (40°–60°) to secure reliable clamping and repeatable positioning. Selecting the matching holder and clamping set ensures the designed cutting geometry is realised at the tool tip, which is essential for consistent component tolerances and predictable tool performance. Where necessary, choose the chipbreaker and grade to match the machining strategy — roughing, semi-finishing or finishing.

Clear guidance for typical applications

Intended primarily for turning, these inserts perform well in both external and internal operations on steel and stainless steels, especially in production environments with frequent material changes or where tool robustness is critical. The AH725 grade is particularly suitable for smaller-tool setups and applications that demand high process security rather than extreme metal-removal rates. When programmed cutting data are combined with stable fixturing and the correct insert geometry, the result is reproducible component quality and fewer process interruptions.
