TPMT16T304-PM T6215 – ISO turning insert, CVD-coated carbide for stainless steel

TPMT16T304-PM T6215 is an ISO-format indexable insert designed for turning operations, suited to stable and slightly interrupted cuts in stainless steel.

• CVD-coated carbide grade T6215
• Optimised chipbreaker PM
• 16 mm triangular form, 60° included angle
• 11° clearance with 0.4 mm corner radius

High-performance wear resistance for consistent turning results

The CVD-coated carbide composition T6215 provides a balanced combination of hardness and toughness, designed to extend tool life when machining stainless steel under stable conditions. The CVD coating reduces flank and crater wear, which translates into longer intervals between index changes and more predictable batch quality. For production-focused environments this means fewer interruptions and steadier dimensional tolerance control.

Geometry engineered for secure clamping and repeatability

The triangular 16 mm format with a 60° included angle and a 0.4 mm corner radius creates a stable cutting edge geometry that is easy to seat in standard ISO turning holders. The insert’s 3.97 mm thickness and the specified 11° clearance support rigidity in light to medium cutting forces. Compatibility with a holder depends on shape, clearance, tolerance class, fastening method, size and thickness; these parameters ensure reliable repeatability across tool changes and simplify setup procedures.

Chip control and process stability through the PM chipbreaker

The PM chipbreaker is tailored for the material and the grade; it promotes controlled, short chips when turning tough-to-machine stainless alloys, reducing the risk of chip entanglement and workpiece surface damage. Combined with the T6215 carbide substrate, the chipbreaker helps maintain cutting-edge integrity under fluctuating cut conditions, improving surface finish and lowering the likelihood of built-up edge formation. The result is higher process security and more efficient throughput.

Practical selection and integration into existing tooling systems

As an ISO-standard insert, the component integrates into established systems comprising the insert, a compatible external holder or boring bar, a seat/pad or clamp set and replacement screws. The presence of a cylindrical hole with a one-sided countersink (40°–60°) supports secure fixture and simplifies inventory handling. When selecting the chipbreaker and grade, preference should be given to combinations that match the workpiece alloy, machining mode and machine stability for optimal cost-efficiency and surface integrity.

FAQ

What materials is this insert intended for?
The TPMT16T304-PM T6215 insert is specified for machining stainless steel under stable to slightly interrupted cutting conditions, utilising the T6215 CVD-coated carbide for wear resistance.

How does the PM chipbreaker affect machining?
The PM chipbreaker promotes short, controlled chips when turning stainless alloys; on the TPMT16T304-PM the chip control helps protect the workpiece surface and reduces downtime associated with chip handling.

Which holders are compatible with this ISO insert?
Compatibility depends on the holder’s form, clearance angle, tolerance class, fastening method, size and thickness; standard ISO external holders and boring bars that accept a 16 mm triangular insert with a central hole are suitable for the TPMT16T304-PM.

What are the key geometry values to note for setup?
Key values include a 16 mm insert size, 3.97 mm thickness, 0.4 mm corner radius, 11° clearance and a 60° included angle, which influence seating, rigidity and cutting engagement.

Is this an original Tungaloy part and how is it identified?
Yes; the product is an original Tungaloy indexable insert identified by article number 6877321 and SKU 6877321-Tungaloy.
