DCMT11T304 AH725 indexable turning insert — ISO-standard, PVD-coated carbide by Tungaloy

DCMT11T304 AH725 is an ISO-standard indexable insert designed for external and internal turning, offering universal performance across mixed materials and high process security

• PVD-coated AH725 universal grade
• ISO DCMT11T304 rhombic 55° geometry
• 0.4 mm corner radius for fine finishes
• Cylindrical hole with 40°–60° countersink

Consistent results across Stahl and rostfreier Stahl for mixed-production runs

The PVD-coated carbide grade AH725 delivers a balance of wear resistance and edge toughness that suits batch production with varying materials. Its formulation supports stable chip formation and reduces the risk of edge chipping when machining both Stahl and rostfreier Stahl, making the insert appropriate for shops that face frequent material changes. The single sided chipbreaker contributes to controlled chip flow, which in turn lowers interruption risk and helps maintain cycle times—valuable where process security and repeatability are priorities.

Precision fit and ISO compatibility to shorten setup times

Built to the ISO-standard form DCMT11T304, the rhombic 55° geometry ensures a predictable contact angle for turning operations, while the cylindrical hole with one-sided countersink (40°–60°) enables secure clamping in standard holders. Compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness, which simplifies tool selection for compatible holders and reduces adapter requirements. The result is faster changeovers and fewer alignment adjustments during tool replacement.

Stable cutting performance and economical tool life

The combination of the AH725 coating and carbide substrate provides robust wear characteristics for small to medium-sized tools and demanding finishing tasks. The 0.4 mm corner radius supports fine surface finishes without sacrificing edge strength, and the plate thickness of 3.97 mm contributes to rigidity in the clamped system. Overall, this design promotes consistent tool life and lowers the frequency of insert changes, improving uptime and delivering a favourable cost-in-use for production environments that prioritise both quality and efficiency.

FAQ

Is this insert suitable for machining rostfreier Stahl?
Yes. The DCMT11T304 AH725 insert from Tungaloy is designed as a universal, breakage-resistant grade suitable for machining both Stahl and rostfreier Stahl, offering stable cutting and controlled chip formation.

Which holder types are compatible with this insert?
Compatibility depends on holder form, relief angle, tolerance class, fastening method, size and thickness; the ISO DCMT11T304 form is compatible with standard rhombic 55° external and internal turning holders designed for that insert geometry.

What surface finish can be expected with the 0.4 mm corner radius?
A 0.4 mm corner radius supports fine finishing operations while maintaining edge strength; paired with the AH725 PVD coating, it helps achieve consistent surface quality and repeatable part tolerances.

What is the hole and fastening style of the insert?
The insert features a cylindrical hole with a one-sided countersink between 40° and 60°, enabling secure clamping in compatible ISO holders.
