SNMG 120408 AH725 Tungaloy indexable turning insert — for ISO-based turning applications

The SNMG120408 AH725 Tungaloy insert is a square, double-sided ISO indexable insert designed for external and internal turning; compatible with holders that match form, relief angle, tolerance class, clamping and plate dimensions.

• PVD-coated AH725 for mixed materials
• Square, 90° geometry with 0.8 mm radius
• Double-sided insert with cylindrical hole
• ISO‑standardised SNMG 120408 form

Stable process security through a universal, PVD-coated grade

The AH725 grade is a PVD-coated carbide developed for universal use, offering stable chip formation and resistance to edge breakage when machining a range of steels and stainless steels. For operations where material mixes occur or tool sizes are modest, this grade improves process reliability and reduces unplanned tool changes. The coating enhances wear resistance and helps maintain cutting-edge integrity under varying cutting conditions, which supports consistent cycle times and predictable tool life.

Geometry that delivers repeatable precision and easy indexing

The square SNMG geometry with a 90° included angle and 0.8 mm corner radius provides a predictable cutting profile for finishing and medium machining. The plate thickness of 4.76 mm and the central cylindrical hole enable secure clamping and straightforward indexing; being double-sided effectively doubles the usable edges per insert. This combination results in reliable clamping behaviour, repeatable part dimensions and straightforward maintenance of cutting geometry in serial production.

System compatibility and selection guidance for efficient integration

Compatibility depends on form, relief angle (0° free angle), tolerance class, clamping method, size and thickness; the ISO model series ensures straightforward matching with standard external holders, boring bars, shims and clamp sets. Choose the double-sided chipbreaker style that matches material and stability requirements to optimise chip control and surface finish. For mixed-material applications and processes with high demands on security, the AH725 grade is a sound choice that balances wear resistance and fracture toughness.

FAQ

What materials is this insert suitable for?
The SNMG120408 AH725 Tungaloy indexable insert is designed for machining a broad range of steels and stainless steels; the AH725 PVD-coated carbide provides balanced wear resistance and toughness for mixed-material work.

How does the 0.8 mm corner radius affect machining performance?
A 0.8 mm corner radius on the SNMG 120408 insert increases edge strength for finishing and light-medium turning, improving surface finish consistency while reducing the risk of radius-related breakouts.

Is the insert reversible and how many cutting edges are available?
The square, double-sided design offers four usable cutting edges per side for a total of eight potential edges, depending on the chosen indexing and regrinding strategy for the SNMG120408 AH725 Tungaloy insert.

Which holders and clamping components are required for proper compatibility?
Compatibility is determined by form, free angle, tolerance class, clamping and plate dimensions; an ISO‑compliant external turning holder, the correct shim and clamp set, and matching hex screws ensure secure clamping of this insert.

What is the manufacturer SKU and article number for ordering?
Article number 6861212 and manufacturer SKU TUN6861212 identify the SNMG120408 AH725 Tungaloy insert for procurement and inventory purposes.
