TNMA 110408 T515 Turning insert — Tungaloy, CVD-coated carbide, 60°

The TNMA110408 T515 is an ISO triangular turning insert designed for economical external and internal turning of cast iron components, offering consistent edge stability and straightforward holder compatibility

• ISO triangular insert for turning operations
• CVD-coated carbide grade T515 for cast iron
• 60° included angle for versatile geometry
• Cylindrical hole for secure clamping

Efficient cast iron machining with optimised coating

The CVD-coated carbide grade T515 provides a balance between wear resistance and economic performance for cast iron machining. The coating reduces flank wear and maintains a sharp cutting edge over longer cycles, which translates into fewer indexings and lower tooling costs per component. In practice, the optimised surface finish and predictable abrasion behaviour support stable cycle times on series production, while the insert’s hard substrate keeps edge integrity under moderately interrupted cuts.

Secure fit and reduced setup variability

Compatibility with toolholders is governed by insert form, clearance angle, tolerance class, fastening method, size and thickness; this ensures a reliable seating and clamping force. The triangular geometry and the cylindrical hole allow positive engagement in many ISO holders, reducing micro-movements and setup adjustments. As a result, mounting precision is improved, repeatability in batch runs is increased and downtime for re-clamping is minimised, which benefits throughput and process stability.

Geometry tuned for performance and edge life

The 60° included angle combined with a 0.8 mm corner radius delivers a robust cutting edge suited to general turning tasks and light finishing passes on cast iron. The insert thickness of 4.76 mm and triangular form contribute to rigidity at the cutting edge, reducing vibration and supporting consistent dimensional results. Note that this grade is supplied without a chipbreaker; selection of cutting parameters and coolant strategy should reflect the absence of an integrated chip control feature to maintain chip evacuation and surface quality.

Practical handling, selection and application guidance

Designed as part of the ISO turning insert family, this insert integrates into standard assemblies comprising an external holder or boring bar, backing pad/clamp set and replacement screws. Selection of a suitable chipbreaker and matching grade depends on workpiece stability and required cutting speed; the T515 grade is recommended when economic removal of cast iron material is the priority. For short-term process optimisation, adjust feeds to exploit the 0.8 mm radius for improved surface finish while preserving edge life.

FAQ

Which materials are recommended for this insert?
The TNMA110408 T515 insert is optimised for cast iron machining; the T515 CVD-coated carbide provides wear resistance and economic removal rates for such materials.

Is the insert compatible with standard ISO holders?
Compatibility depends on insert form, clearance angle, tolerance class, fastening method, size and thickness; the TNMA110408 follows ISO geometry and fits matching ISO triangular holders when those parameters align.

Does this grade include a chipbreaker?
This insert is supplied without a chipbreaker; chip control should be managed through cutting parameters or by choosing a compatible insert with an integrated breaker for specific applications.

What are the key geometry values for setup calculations?
Key figures: included angle 60°, corner radius 0.8 mm, thickness 4.76 mm and inscribed circle 11.

How is the insert secured in the holder?
The insert features a cylindrical hole and is designed to be clamped with a suitable screw and backing arrangement to ensure stable seating in ISO holders.
