TCMT 16T302 AH6225 – TCMT16T302-PS turning insert (0.2 mm radius) by Tungaloy

The TCMT16T302-PS AH6225 is an ISO-format triangular turning insert designed for external and internal turning of stainless steels, offering a balanced combination of edge sharpness and stability for medium cutting conditions.

• PVD-coated carbide for long tool life
• Designed for stainless steel machining
• ISO-standard triangular insert, 60° geometry
• 0.2 mm corner radius for fine finishing

Efficient metal removal with consistent edge life

The combination of a PVD-coated surface and the AH6225 grade of carbide delivers a durable cutting edge while retaining enough sharpness for demanding stainless steel tasks. This balance ensures stable performance during medium-duty turning operations and helps reduce workpiece rework. The chipbreaker PS supports controllable chip formation under variable cutting conditions, improving process predictability and reducing the frequency of tool changes. For workshops aiming to maintain throughput while preserving surface quality, the engineered pairing of coating and substrate yields measurable gains in uptime and component consistency.

Smooth integration into ISO tooling systems for predictable results

Compatibility with toolholders is determined by geometry, relief angle, tolerance class, clamping method, size and thickness. The insert follows ISO conventions, so the mechanical fit with a matching external holder or boring bar is straightforward when those parameters align. The overall system comprises the indexable insert, an appropriately rated holder, a shim or clamping set and the retaining screw; correct assembly minimises vibration and supports repeatable cuts. Laboratory measurements and in-shop trials benefit from this standardisation, as operators can swap inserts rapidly while maintaining process settings and expected part tolerances.

Fine finishing and practical selection guidance for turning tasks

The triangular form and 60° included angle offer versatile cutting orientations and three indexed cutting edges per insert, while the 0.2 mm corner radius supports fine finishing without compromising edge strength. Plate thickness of 3.97 mm and the central hole with a cylindrical bore plus a single-side countersink (40°–60°) ensure secure clamping and stable performance under lathe feeds typical for finishing and semi-finishing passes. When selecting a chipbreaker and grade, choose the chip control and edge preparation that match material characteristics and machine rigidity — for stainless steels under mixed conditions, the AH6225 grade with chipbreaker PS is a dependable choice that balances wear resistance and cutting stability.

FAQ

Is this insert suitable for stainless steel turning applications? Yes. The TCMT16T302-PS in AH6225 grade is specifically designed for machining stainless steels and combines a PVD-coated carbide substrate with the PS chipbreaker to control chips and maintain edge stability.

What does the 0.2 mm corner radius affect in practice? A 0.2 mm corner radius helps achieve finer surface finishes and reduces the risk of cutting-edge chipping during finishing passes; the radius is a compromise between edge strength and surface quality for many turning operations.

How does the insert fasten to a holder? The triangular insert uses a central bore with a cylindrical hole and single-side countersink (40°–60°) to enable secure clamping in compatible ISO-format holders and boring bars; ensure holder geometry matches the insert form and tolerance class.

Can this insert be used for internal turning as well as external turning? Yes. The ISO triangular geometry and 60° included angle make the insert suitable for both external and internal turning, provided an appropriate holder or boring bar is selected for the operation.

What should be considered when choosing the chipbreaker? Select the chipbreaker according to workpiece material, feed rate and machine rigidity; the PS chipbreaker on this insert is intended to offer predictable chip control for variable conditions in stainless steel machining.
