TPMT 130304 T6215 — ISO triangular turning insert for turning (Tungaloy)

The TPMT130304-PM T6215 is an ISO-standard triangular insert designed for external and internal turning, optimised for rostfreier Stahl under stable to mildly interrupted cutting conditions

• CVD-coated carbide grade T6215
• ISO triangular form, 60° included angle
• 0.4 mm corner radius for fine finishes
• Chipbreaker PM for stable chip control on rostfreier Stahl

Increased process reliability through optimised coating and grade

The CVD-coated carbide grade T6215 combines wear resistance with predictable edge behaviour, which translates into longer tool life and fewer insert changes during batch production. Using a CVD coating means the cutting edge resists abrasive wear and thermal softening better than uncoated grades; this is particularly valuable during machining of rostfreier Stahl, where built-up edge and rapid flank wear are common. The net effect is improved uptime and more consistent component tolerances, supporting higher productivity in stable cutting regimes.

Consistent surface quality and chip control for turning tasks

The triangular ISO geometry with a 60° included angle and a 0.4 mm corner radius delivers a balance between strength and finish capability. The PM chipbreaker is shaped to promote short, controllable chips on typical turning passes, reducing the risk of entanglement and tool damage. For parts requiring a fine finish, the small corner radius helps achieve tighter surface roughness values while maintaining edge robustness; for roughing passes, the same insert provides the stability needed for heavier cuts when machine and setup stiffness allow.

Compatibility and simple integration into existing systems

Compatibility with toolholders depends on form, relief angle, tolerance class, clamping style, size and thickness; the ISO designation ensures broad fitment with standard external holders or boring bars. The insert’s 3.18 mm thickness and central hole with cylindrical bore plus single-sided countersink (40°–60°) enable secure clamping and repeatable positioning. Selecting matching holders and correct clamp torque yields axial and radial stability that supports repeatable part accuracy across batches.

Operational economy and application advice

Choosing this ISO triangular insert helps reduce overall machining costs by lowering changeover frequency and improving process stability. The insert is tailored for turning of rostfreier Stahl under steady or slightly interrupted cutting conditions; for heavily interrupted cuts or unstable setups, consider more robust geometries or adjust cutting parameters. The combination of CVD coating, grade T6215 and the PM chipbreaker provides a pragmatic solution for general turning tasks where wear resistance and chip control are priorities.

FAQ

What materials is this insert suited for?
The TPMT130304-PM T6215 is optimised for machining rostfreier Stahl and performs well under stable to lightly interrupted turning conditions.

What does the chipbreaker PM do?
The PM chipbreaker on this insert promotes short, controlled chips, improving process stability and reducing the risk of chip-related interruptions during turning.

How does the 0.4 mm corner radius affect the finish?
A 0.4 mm corner radius balances edge strength and surface quality, enabling finer finishes than larger radii while retaining sufficient toughness for standard turning passes.

Is the insert compatible with standard ISO holders?
Yes, the insert follows ISO geometry; compatibility is determined by form, relief angle, tolerance class, clamping and size—use holders matched to the ISO triangular form and 3.18 mm thickness.

Can it be used for internal turning as well as external turning?
The insert’s triangular shape and mounting hole design allow use in both external holders and suitable boring bars for internal turning applications when holder geometry is compatible.
