• 0.8 mm corner radius
• 11° clearance angle

Higher productivity through a balanced cutting grade

The CVD-coated T5115 grade is designed to offer a reliable compromise between wear resistance and cutting-edge stability, making it well suited to repetitive turning operations in cast iron. A CVD coating forms a hard, wear-resistant layer that reduces flank wear and helps maintain consistent component dimensions over longer tool life. For production environments this translates into fewer tool changes and a steadier process window, which supports higher throughput and predictable cycle times.

Secure clamping and geometry that aids surface quality

The 60° triangular geometry combined with a 0.8 mm corner radius provides a robust cutting edge that tolerates interrupted cuts while still enabling good surface finish on turned parts. The insert’s 11 mm size and 3.18 mm thickness contribute to rigidity in the toolholder, and the cylindrical hole with single-sided countersink (40°–60°) ensures precise location and secure clamping. Compatibility with holders depends on form, relief angle, tolerance class, fixing method, size and thickness; verify these parameters against the chosen toolholder to achieve repeatable clamping and consistent component quality.

Application guidance and selection advice for reliable results

Typical operations include both external and internal turning; the supplied chipbreaker CM is intended to manage chips in many cast iron applications but should be matched to workpiece grade, machining strategy and machine stability. When machining cast iron, a stable setup and conservative feed/speed starting point extend the effective life of the insert. The ISO-standard format allows straightforward replacement and inventory management. For process optimisation, consider the balance between corner radius and feed rate: a larger radius improves edge strength but requires higher feeds to avoid increased cutting forces. For bespoke recommendations, Metav Werkzeuge can assist with parameter selection and stock queries.

FAQ

What materials is this insert best suited for?
The TPMT110308-CM T5115 insert uses a CVD-coated carbide grade optimised for cast iron applications, offering balanced wear resistance and edge stability for typical grey and nodular cast iron turning.

How does the 0.8 mm corner radius affect the machining result?
A 0.8 mm corner radius increases edge strength and resistance to chipping during interrupted cuts; with the TPMT 110308 T5115 this radius supports robust performance while maintaining an acceptable surface finish when paired with appropriate feeds.

Can this insert be used for internal turning as well as external turning?
Yes, the triangular ISO format and the insert’s geometry make it suitable for both external and internal turning operations when used with a compatible holder and correct mounting.

What does the CM chipbreaker offer in practice?
The CM chipbreaker is designed to control chip formation in many cast iron turning tasks, promoting consistent chips that evacuate well and reduce risk of entanglement at moderate cutting parameters.

How should compatibility with a toolholder be checked?
Verify the holder’s pocket form, relief/facing angle, tolerance class, fixing method, insert size and thickness against the ISO insert specifications; these parameters determine correct seat and secure clamping for the TPMT110308-CM T5115.
