TPMT 130308 T6215 triangle insert for turning — Tungaloy, CVD-coated carbide, 0.8 mm radius

TPMT130308-PM T6215 is an ISO triangle turning insert intended for general external and internal turning where stable to slightly interrupted cuts are expected

• CVD-coated carbide grade T6215
• ISO triangle insert 130308, 60° included angle
• 0.8 mm corner radius for profile stability
• 11° clearance angle, with cylindrical hole and countersink

Consistent wear resistance for rostfreier Stahl turning

The combination of a CVD-coated layer with a wear-resistant carbide substrate (grade T6215) is designed to extend tool life during continuous production. This coating, applied in a controlled process, forms a hard surface that reduces flank wear and improves resistance to adhesion and abrasive mechanisms encountered when machining rostfreier Stahl. As a result, machining intervals can be lengthened and unpredictable edge failures reduced, which supports higher uptime in turning operations.

Geometry engineered for reliable dimensional control

The ISO 130308 triangular form, with a 60° included angle and a 0.8 mm corner radius, provides stable cutting edges that preserve part geometry across repeated passes. The insert’s 11° clearance (relief) angle helps to avoid rubbing on the workpiece while maintaining sufficient support in the pocket. The 3.18 mm plate thickness contributes to rigidity, especially when used with a suitable external holder or boring bar; compatibility is determined by form, clearance angle, tolerance class, fastening and the insert’s size and thickness.

Chip control and mounting details that reduce setup time

Equipped with the PM chipbreaker, the insert aids controlled chip formation for a range of feed rates and depths of cut, reducing the need for secondary chip-management devices. The plate is supplied with a cylindrical hole and a one-sided countersink (40°–60°) to match standard clamping systems and screw types. Because the system comprises an ISO insert, a matched external holder or bar, a support shim/clamping set and replacement screws, preparation and repeatability of setups are simplified for shop-floor teams.

Application guidance and process advantages

This grade and geometry are recommended where stable to slightly interrupted turning of rostfreier Stahl is required; selection of the correct chipbreaker and grade should be aligned with the workpiece alloy, machining strategy and machine stability. Using this insert in a correctly matched holder will typically reduce cycle time variability and improve surface consistency. The insert is particularly suitable for production environments seeking a balance between productivity and predictable tool life.

Material and maintenance considerations

Made from a premium carbide substrate with CVD coating, the insert is supplied as a spareable cutting edge rather than a resharpenable tip; replacement is straightforward and keeps machine downtime to a minimum. For optimal performance, ensure that holders are within the specified tolerance class and that clamping hardware is torque-controlled; this preserves the insert seat and prevents micro-movements that could degrade edge life.

FAQ

What materials is this insert suited for?
The TPMT130308-PM T6215 is formulated for turning rostfreier Stahl, offering improved wear resistance under stable to slightly interrupted cutting conditions.

How does the T6215 coating benefit production runs?
The CVD-coated T6215 grade on the TPMT130308-PM insert reduces flank wear and supports stable chip formation, which prolongs edge life and lowers the frequency of tool changes.

Which holder features ensure correct compatibility?
Compatibility depends on insert form, clearance angle, tolerance class, fastening, size and thickness; the TPMT geometry requires a matching triangular pocket and screw/clamp arrangement for secure seating.

Can the insert handle interrupted cuts?
Yes; the grade and PM chipbreaker are intended for stable to slightly interrupted turning, though heavy interruptions may require a more robust cutting strategy.

What is the effect of the 0.8 mm corner radius?
A 0.8 mm corner radius supports consistent profile control and improved edge strength, reducing the tendency for micro-chipping on peripheries and aiding surface quality.
