TCMT16T304 AH6235 triangular turning insert, PVD-coated carbide (Tungaloy)

A TCMT16T304 AH6235 ISO triangular turning insert for external and internal turning, offering a 0.4 mm corner radius, a 7° clearance angle and a single‑sided chipbreaker for controlled chip formation

• Tough PVD-coated carbide grade AH6235
• ISO‑standard TCMT 60° triangular shape
• 0.4 mm corner radius for fine profiling
• Single‑sided chipbreaker, with centre hole

Consistent performance in demanding stainless-steel turning

The TCMT16T304 AH6235 insert is engineered for robust performance when machining stainless steel and other challenging alloys. The AH6235 grade is a tougher, PVD-coated carbide designed to resist chipping under interrupted cuts and in unstable cutting conditions. This results in fewer unplanned tool changes and a steadier production flow. By selecting a grade optimised for breakage resistance, process reliability is improved while the risk of workpiece rework is reduced.

Geometry that enhances accuracy and surface finish

A triangular 60° geometry combined with a 0.4 mm corner radius and a 7° clearance delivers a balance between profile definition and edge strength. The small corner radius supports fine turning and accurate contouring, while the clearance angle reduces rubbing and heat build-up at the flank, contributing to a better surface finish. These geometric choices reduce the likelihood of built-up edge and make the insert suitable for finishing and semi‑finishing passes where dimensional control is essential.

Secure clamping and compatibility for shop workflows

ISO standardisation of the insert form ensures wide compatibility with common toolholders and boring bars; compatibility must be checked by form, clearance angle, tolerance class, attachment method, size and thickness. The insert’s centre hole and cylindrical hole style with a one-sided countersink (40°–60°) provide reliable mechanical location and clamping stability. The single‑sided chipbreaker is tailored for one-sided cutting directions, helping to guide chips away from the cutting zone and to maintain consistent chip control in serial production.

Practical advantage: selection and handling

Choosing the correct chipbreaker and grade according to material and process stability reduces downtime and scrap. The insert’s 3.97 mm thickness and triangular form allow cost‑effective indexing of multiple cutting edges, extending usable life per insert. For applications with interrupted surfaces or higher breakout risk, the tougher AH6235 grade mitigates edge chipping and extends edge life, offering a favourable cost‑per‑cut advantage in many turning operations.

FAQ

Which materials is this insert suitable for?
The AH6235 grade is formulated for stainless steel and similar tough materials; the insert is suitable for external and internal turning where improved breakage resistance is required.

Can the insert handle interrupted cuts?
Yes, the tougher AH6235 PVD‑coated carbide is intended for applications with interrupted cutting and increased risk of chipping, offering enhanced edge robustness.

How is the insert clamped and located?
Clamping uses the central hole; the insert features a cylindrical hole with a one‑sided countersink (40°–60°) for secure mechanical location and stable clamping in compatible holders.

What does the single‑sided chipbreaker mean in practice?
A single‑sided chipbreaker is designed to control chip formation for a specific cutting direction, guiding chips away from the cutting zone and improving chip evacuation during turning.

Is the insert compatible with ISO toolholders?
The insert follows ISO dimensions for triangular turning inserts, but compatibility depends on form, clearance angle, tolerance class, attachment and thickness; match the insert to the holder specifications for safe use.
