WNMG080408-TM AH725 indexable turning insert — trigon 80° geometry, PVD-coated carbide (Tungaloy)

The WNMG080408-TM AH725 is an ISO-format indexable insert for external and internal turning, offering a universal, fracture-resistant grade suited to mixed-material production runs.

• PVD-coated AH725 grade for steel and stainless steels
• Trigon geometry with 80° approach angle
• 0.8 mm corner radius for sturdy cutting edge
• Cylindrical hole, compatible with ISO holders

Maximise process reliability with a universal, fracture-resistant grade

The PVD-coated AH725 grade delivers a balance between edge strength and wear resistance, making it a reliable choice for demanding turning operations on both steel and stainless steels. As a PVD-coated carbide solution, the insert reduces the risk of premature edge failure in interrupted or variable-cut conditions; this supports consistent cycle times and fewer tool changes. Selecting a universal grade is particularly advantageous where workpiece materials vary or where smaller tooling must withstand high demands on process reliability.

Geometry engineered for stable cutting and consistent surface quality

The trigon shape and 80° geometry provide a robust cutting interface that spreads cutting forces across the insert body, improving stability for external and internal turning. The 0.8 mm corner radius offers increased edge strength for roughing and general turning tasks while preserving a defined cutting line for finishing passes. Combined with the TM chipbreaker, the geometry encourages controlled chip formation and evacuation, which helps maintain repeatable surface integrity and reduces the likelihood of built-up edge under fluctuating cutting conditions.

Practical integration into ISO tool systems for efficient workshop use

Designed as an ISO-format indexable element, the insert is compatible with standard clamping systems where fit is determined by shape, clearance, tolerance class, fixing method, size and thickness. The with hole (cylindrical) configuration ensures reliable positive location and straightforward replacement in compatible holders. Material and coating information allow planners to match the insert to coolant strategy and machining parameters, while the universal nature of the grade simplifies inventory: one PVD-coated carbide variant covers a broad range of turning tasks, reducing tool complexity in production environments.

FAQ

What materials is this insert designed to machine?
The WNMG080408-TM AH725 insert is intended primarily for steel and stainless steels; the AH725 PVD-coated grade is chosen for its universal, fracture-resistant properties suited to varying workpiece materials.

Which chipbreaker is fitted and what does it deliver?
This insert uses the TM chipbreaker, which promotes controlled chip formation and evacuation for consistent surface finish and reduced edge stress in general turning operations.

How is compatibility with a holder ensured?
Compatibility is governed by the insert form, 0° clearance, tolerance class, fixing method, plate size and thickness; the ISO format and cylindrical hole facilitate accurate seating in compliant ISO external and internal turning holders.

Is the insert suitable for small-tool applications and mixed-material batches?
Yes, the universal AH725 grade is recommended where materials change frequently or where smaller tooling is used, because it balances edge robustness with good wear behaviour.

What are the key identification details for ordering?
