TCMT16T304 AH6235 indexable insert for turning by Tungaloy — PVD-coated, 0.4 mm radius

TCMT16T304 AH6235 is a triangular, ISO-format turning indexable insert intended for external and internal turning where interrupted cuts and stainless steel workpieces demand a tougher grade and controlled chip behaviour.

• PVD-coated grade AH6235
• Designed for stainless steel & interrupted cuts
• Triangular insert, 16 mm size, 0.4 mm radius
• Cylindrical hole with 40°–60° countersink

Increase throughput with a tougher PVD grade

The PVD-coated AH6235 grade combines toughness with a protective coating to resist edge chipping during unstable cuts. For machining stainless steel and operations with repeated interruptions, this composition reduces unplanned tool changes and improves process stability. The result is a measurable improvement in uptime and consistent component surfaces under challenging conditions.

Secure mounting and ISO compatibility for predictable results

Built to ISO geometries, the insert matches standard holders by form, clearance angle and size, ensuring interchangeability within established tool systems. The 7° relief angle and a plate thickness of 3.97 mm contribute to reliable clamping and repeatable cutting conditions. The ISO conformity simplifies inventory management and reduces downtime associated with non‑standard tooling.

Chip control and edge life tailored for difficult cuts

The triangular form and single-sided chipbreaker are designed to direct chips away from the cut while maintaining a stable cutting edge. The 0.4 mm corner radius provides a compromise between edge strength and surface finish, making the insert suitable for medium-duty finishing and roughing passes where breakout risk is elevated. The central hole with a 40°–60° countersink supports secure fastening and correct seat location in the cutter body.

Practical system benefits for the workshop

As part of an insert system, the component integrates with matching external holders, shim sets and replacement screws to form a complete, serviceable solution. Standardisation across the model series helps reduce setup time and enables quicker tooling decisions on the shopfloor. Backed by Tungaloy’s manufacturing expertise, the insert offers consistent performance that supports stable process control and cost-effective production.

FAQ

What materials is this insert suitable for?
The TCMT16T304 AH6235 insert is formulated for machining stainless steel and is particularly resilient in interrupted cuts where edge chipping can occur.

How does the AH6235 grade affect tool life?
The PVD-coated AH6235 grade offers increased toughness and wear resistance, which extends edge life under unstable cutting conditions compared with uncoated grades.

Is the insert compatible with standard ISO holders?
Yes. The TCMT16T304 follows ISO insert geometry, so compatibility depends on matching the holder form, clearance angle, tolerance class, fastening and thickness.

What advantages does the 0.4 mm corner radius provide?
The 0.4 mm radius strengthens the cutting edge against breakouts while still allowing acceptable surface finish, making it suitable for mixed finishing and light roughing tasks.

Can the insert handle interrupted or unstable cuts?
The combination of the AH6235 grade and single-sided chipbreaker is designed to improve resistance to edge chipping, making it appropriate for interrupted and unstable turning operations.
