WNMG 080404 AH905 — WNMG080404-HMM indexable turning insert for turning by Tungaloy

WNMG080404-HMM AH905 is an ISO-format indexable insert designed for external and internal turning, offering a PVD-coated cemented carbide grade for stable cutting and process security.

• PVD-coated cemented carbide grade AH905
• Trigon shape for secure clamping
• Corner radius 0.4 mm for fine surface finish
• Compatible with ISO turning holders

Consistent cutting performance with reduced tool change

The PVD-coated cemented carbide grade AH905 provides a balance of wear resistance and a sharp cutting edge, suited where process security and edge integrity are required. As an ISO-compliant turning insert, the design promotes predictable behaviour during continuous machining; the PVD coating reduces flank wear while maintaining edge sharpness, which in turn improves tool life and reduces downtime. This rationale supports improved productivity and a lower cost per component when used in standard turning operations.

Precision fit and straightforward integration into ISO tool systems

Designed as an ISO turning plate, the WNMG080404-HMM ensures compatibility through defined form, relief angle, tolerance class, fastening and thickness, enabling straightforward integration with matched outside holders or boring bars. The trigon shape and cylindrical hole deliver stable clamping and repeatable seating; the 0° relief angle and 80° wedge angle support versatile approaches to external and internal turning. Selection of the appropriate chipbreaker and grade should follow workpiece stability and machining strategy to achieve the desired surface quality and process reliability.

Stable chip control and reliable edge life for shop-floor demands

The insert’s geometry, including a corner radius of 0.4 mm, and the HMM chipbreaker, are intended to aid controlled chip formation under varying cutting conditions. The result is a reduction in unexpected edge chipping and an improvement in consistent dimensional outcomes across batches. For operations prioritising uninterrupted throughput, this combination of coating, substrate and chip control contributes to reproducible part quality and predictable tool change intervals, supporting long-term process planning and operational efficiency.
