TCMT 110204 AH6235 Tungaloy indexable insert for turning — PVD-coated carbide, 60° triangle

The TCMT110204 AH6235 indexable insert is an ISO‑standard triangular turning insert designed for external and internal turning, optimised for stainless steels and applications with increased risk of edge chipping.

Higher process reliability for stainless steel and interrupted cuts

The PVD‑coated AH6235 grade is formulated as a tougher carbide mix to withstand the demands of stainless steel machining and intermittent cuts. This composition reduces the tendency for brittle fracture at the cutting edge and promotes stable chip formation, which keeps component surfaces consistent and lowers the frequency of tool changes. The combination of a tougher substrate and PVD surface treatment improves resistance to adhesive wear and micro‑chipping, yielding a more predictable service life under unstable cutting conditions.

Secure clamping and simple integration into ISO tool systems

Engineered to ISO dimensions, the triangular insert provides a standardised seating and orientation for quick integration into holders. The 60° included angle, 2.38 mm thickness and the cylindrical hole with single‑sided countersink (40°–60°) facilitate reliable clamping and repeatable positioning in compatible external holders or boring bars. Clear specification of form, relief angle and tolerance class simplifies selection of the matching toolholder, shims and replacement screws, reducing set‑up time and the risk of incorrect assembly.

Efficient cutting performance and practical selection guidance

The 0.4 mm corner radius combined with a one‑sided chipbreaker offers a controlled cutting edge suitable for mixed finishing and semi‑finishing tasks where interrupted cuts occur. The chipbreaker geometry directs chips away from the workpiece and tool margin, lowering heat concentration and minimising rework. For best results, match the chipbreaker and grade to the workpiece stability and the chosen cutting parameters; when stability is limited, the tougher grade and restrained radius help maintain edge integrity while still delivering a good surface finish. System components typically include a matching outer holder or boring bar, a shim or clamp set and spare fixing screws.

FAQ

What materials is this insert best suited for?
The TCMT110204 AH6235 insert is optimised for stainless steel machining and performs well in interrupted cuts where edge toughness is required.

How does the AH6235 coating benefit cutting performance?
The PVD coating on the AH6235 grade reduces adhesive wear and enhances edge life, while the tougher substrate helps prevent chipping during unstable cuts.

Which toolholders are compatible with this ISO insert?
ISO holders designed for triangular TCMT inserts with a 60° included angle and 2.38 mm thickness will accept this insert when the holder geometry, relief angle and tolerance class match the insert specification.

What is the purpose of the cylindrical hole and countersink?
The cylindrical hole with a single‑sided countersink (40°–60°) secures the insert in the pocket and ensures accurate seating and repeatable clamping torque for consistent positioning.

What operations suit the 0.4 mm corner radius and one-sided chipbreaker?
A 0.4 mm corner radius with a one‑sided chipbreaker is suitable for finishing to semi‑finishing passes and for conditions with intermittent cutting where controlled edge strength and chip evacuation are priorities.
