TCMT16T308 AH6235 TCMT turning insert (PVD-coated carbide, 0.8 mm) — Tungaloy

The TCMT16T308 AH6235 Tungaloy turning insert is an ISO triangular insert designed for external and internal turning, optimised for stainless steels and intermittent cutting conditions.

• PVD-coated carbide grade AH6235
• ISO TCMT 16T308 triangular insert
• 0.8 mm corner radius for finishing
• Cylindrical hole with single-sided countersink

Greater process reliability and extended tool life

The PVD-coated AH6235 grade offers a balanced combination of toughness and wear resistance that improves performance when machining stainless steel and mixed-material batches. The PVD-coated carbide surface reduces adhesive wear and helps maintain a stable cutting edge during interrupted cuts, which leads to fewer tool changes and more predictable cycle times. For production environments where material variability and short interruptions are common, this insert supports consistent part quality and reduced rework rates.

Precise geometry for chip control and surface finish

A 0.8 mm corner radius combined with a 7° relief angle produces a secure cutting geometry that favours good surface finish while limiting cutting forces. The one-sided chipbreaker design promotes controllable chip formation in turning operations, decreasing the risk of built-up edge on stainless grades and simplifying chip evacuation. These features translate into economical machining: longer insert life, lower tooling consumption and a more efficient process flow for batch and continuous operations.

Simple integration and practical handling for workshop use

The triangular ISO format ensures wide compatibility with standard external holders and boring bars; compatibility depends on form, relief, tolerance class, fastening method, size and thickness, so correct holder selection remains essential. The insert is supplied with a cylindrical hole and a single-sided countersink (40°–60°) for secure clamping and repeatable seating. Given the standardised form factor and reliable material performance, the insert is suitable for both machine-shop production and maintenance tasks where robustness and fast replacement are priorities.

FAQ

Is this insert suitable for machining stainless steel?
Yes. The TCMT16T308 AH6235 insert is specified for stainless steel applications; the AH6235 grade is formulated to resist chipping and adhesion typical of these materials.

Can the insert handle interrupted cuts and unstable conditions?
The PVD-coated AH6235 grade and robust chip control make this insert appropriate for interrupted cuts and scenarios with elevated breakout risk.

Which holder types are compatible with this insert geometry?
Compatibility depends on holder form, clearance angle, tolerance class and fastening. The triangular ISO format fits standard TCMT holders when size and thickness match.

What is the purpose of the cylindrical hole and countersink?
The cylindrical hole with a single-sided countersink (40°–60°) ensures secure clamping and repeatable seating, improving stability and repeatability in turning operations.

How does the 0.8 mm corner radius influence results?
A 0.8 mm radius balances edge strength and surface finish; it reduces edge chipping risk compared with smaller radii while still allowing fine finishing capability.
