CPMT090304 AH725 Tungaloy – ISO rhombic turning insert for turning (Drehen)

The CPMT090304 AH725 is an ISO-standard rhombic indexable insert designed for external and internal turning, offering a universal, breakage-resistant PVD-coated carbide grade suited to varying workpiece materials and demanding process conditions.

• ISO rhombic insert CPMT090304
• PVD-coated AH725 carbide grade
• For external and internal turning of Stahl and rostfreier Stahl
• Single-sided chipbreaker, with central hole

Reliable machining performance and process security

The combination of a PVD-coated AH725 carbide grade with a 0.4 mm nose radius supports repeatable cutting performance and extended edge life in a wide range of turning tasks. The coating improves wear resistance while the substrate provides toughness; this balance reduces flank wear and minimises unexpected edge failures. For operations where consistent output and reduced rework are priorities, the insert’s design leads to improved uptime and predictable tool-change intervals.

Versatility across materials with controlled chip formation

Designed as a universal, out‑break‑resistant grade, the insert handles mixed production runs involving Stahl and rostfreier Stahl without frequent tool swaps. The one-sided chipbreaker promotes defined chip geometry for stable evacuation in both external and internal turning. Explained simply: the chipbreaker guides chips away from the cutting zone, lowering heat concentration and supporting safer, more efficient cycles on conventional and CNC lathes.

Practical compatibility and straightforward tool integration

The insert conforms to ISO geometry so compatibility with appropriate holders is determined by form, relief angle, tolerance class, fastening, size and thickness. The rhombic form and central hole with a single-side countersink (40°–60°) enable secure clamping, while the 11° relief angle and 80° corner angle suit a wide variety of toolholders. This makes toolset planning simpler and reduces inventory complexity for production shops seeking modular, mix‑and‑match tooling solutions.

Shop-floor benefits that matter to production

By choosing an insert tailored for process security and a broad material spectrum, shops benefit from fewer interruptions, improved surface finish consistency and reduced overall tooling costs per part. The insert’s construction and chip control contribute to safer machining and more predictable cycle times. For facilities aiming to standardise on robust, universally applicable inserts, this option supports higher productivity and streamlined tool management.
