TCMT110308 AH6225 turning insert — PVD-coated carbide, 60° triangle by Tungaloy

TCMT110308 AH6225 is an ISO-format triangular turning insert designed for external and internal turning of stainless steels, offering a sharp yet stable cutting edge for variable machining conditions

• PVD-coated carbide AH6225 for stainless steels
• Sharp yet robust cutting edge design
• Triangular 60° geometry for versatile turning
• ISO-compatible with cylindrical hole + countersink

Optimised grade for dependable stainless-steel machining

The AH6225 grade is a PVD-coated carbide developed for universal performance when machining stainless steels. Its coating improves wear resistance under the typical temperatures and adhesion tendencies of stainless materials, while the substrate preserves a sharp cutting edge that resists chipping in medium-duty operations. As a result, operators benefit from more consistent part quality and reduced tool changes, which supports higher productivity on mixed-batch and changing-condition production runs.

Geometry and chip control that reduce process variations

The insert’s triangular 60° geometry combined with a one-sided chipbreaker yields predictable chip formation and stable cutting forces during both external and internal turning. A 0.8 mm corner radius smooths engagement at the cut edge, helping to avoid burrs on stainless workpieces and prolonging tool life. The insert features a cylindrical hole with single-side countersink (40°–60°) and a 7° clearance, which together ensure secure clamping and repeatable seat location in ISO-compatible holders. These design choices support cleaner surface finishes and more reliable cycle times on the shop floor.

System compatibility and practical application guidance

Delivered as an ISO-format insert, the TCMT110308 AH6225 forms part of a system that requires matching holder geometry, tolerance class, fastening method and thickness for optimal performance. The 3.18 mm plate thickness and 11 mm inscribed circle suit a broad range of external and internal turning tasks where medium removal rates and stable cutting conditions are expected. For best results, select a holder and clamping set that correspond to the insert’s form and tolerance requirements, and choose cutting parameters that account for the material’s work-hardening tendency and thermal behaviour. The combination of the AH6225 grade and Tungaloy’s manufacturing reliability supports predictable results across typical turning operations.

FAQ

What materials is this insert suitable for?
The TCMT110308 AH6225 turning insert is specified for machining stainless steels; the AH6225 grade and PVD coating are tuned to resist adhesion and wear typical for these alloys.

Which chip control can be expected from this insert?
The insert’s one-sided chipbreaker and triangular 60° geometry produce manageable chips under medium-duty turning conditions, supporting consistent surface finish and fewer interruptions.

What clamping and holder features are required?
Secure clamping uses the cylindrical hole with single-side countersink (40°–60°); compatibility depends on matching insert form, 7° clearance, tolerance class, fastening and thickness with the chosen ISO holder.

Is the TCMT110308 AH6225 suitable for both external and internal turning?
Yes — the TCMT110308 AH6225 Tungaloy turning insert (SKU 6951425-Tungaloy) is intended for both external and internal turning operations when paired with the appropriate holder and cutting data.

How does the AH6225 grade affect tool life and finish?
AH6225’s combination of a wear-resistant PVD coating and a substrate optimised for a sharp cutting edge helps maintain finish quality and extend useful tool life in variable machining environments.
