TPMT 16T304 T515 — ISO turning insert (triangular, 60°) by Tungaloy

The TPMT16T304-CM T515 is an ISO triangular turning insert designed for economical machining of cast iron, featuring a CVD-coated carbide grade and a secure hole-and-countersink mounting.

• CVD-coated carbide grade T515
• Optimised for economical cast iron machining
• Triangular 60° form with 0.4 mm corner radius
• Cylindrical hole with 40°–60° countersink

Consistent fit and predictable performance for ISO tooling systems

The insert is manufactured to ISO-standard dimensions, so compatibility with holders is ensured by matching form, 11° clearance, tolerance class, fastening type, size and thickness. This standardisation simplifies tool selection and replacement, which reduces machine downtime. Where insert retention and repeatability are critical, the combination of the cylindrical hole plus the single-side countersink provides a reliable locating and clamping interface that maintains positional accuracy during interrupted cuts.

Material and coating engineered for cost-effective cast iron turning

Built from CVD-coated carbide in grade T515, the geometry supports economical machining of cast iron while offering stable chip formation under varied cutting conditions. The integrated CM chipbreaker is matched to the grade and intended to control chip shape and evacuation, improving process stability and surface integrity. Selection of this grade is advised when balancing cutting speed, tool life and workpiece stability, particularly for applications with frequent cut interruptions or medium cutting speeds.

Geometry and mounting that improve edge strength and rigidity

The 0.4 mm radius at the corner increases edge resilience, helping to resist chipping and extend service life in roughing operations, while the 3.97 mm thickness and 16 mm size contribute to the insert’s rigidity in the toolholder. The 60° triangular form allows three indexable cutting edges per insert, supporting economical edge changes. Supplied as part of a system—insert, external holder or boring bar, shim/clamp and replacement screws—this configuration provides a robust setup for steady productivity and consistent surface finish.
