Consistent cutting performance for cast-iron turning

The CVD-coated T5115 grade provides a balance between wear resistance and edge stability, enabling stable material removal in a wide range of cast-iron applications. As an ISO-standard insert, the triangular geometry with a 60° cutting angle and a 1.6 mm corner radius reduces the risk of premature chipping while maintaining acceptable surface finish, which supports predictable tool life and fewer interruptions on the shop floor. The CVD-coated surface improves thermal resistance, so the cutting edge retains its integrity under typical turning loads.

Secure clamping and broad holder compatibility

Compatibility with a toolholder depends on form, clearance angle, tolerance class, clamping method, size and thickness; the plate’s triangular form and a cylindrical hole offer reliable positive location in dedicated clamping systems. The nominal thickness of 4.76 mm and the ISO designation ensure interchangeability with holders designed for this insert family, simplifying inventory management and reducing setup time. Clear information about holder fitment helps avoid mounting errors and enables consistent, vibration‑free cutting action.

Productivity and economic advantage in series production

Using a universal grade designed for cast iron reduces the need for multiple specialised grades, which can lower tooling complexity and inventory costs. The carbide substrate combined with a CVD-coated surface promotes stable chip formation and predictable wear, contributing to longer maintenance intervals and fewer insert changes. The insert’s geometry suits both external and internal turning operations, making it a versatile choice for batch production where flexibility and uptime are priorities.

How geometry and grade influence result quality

The combination of 1.6 mm corner radius and 60° geometry influences cutting forces and achievable surface finish: a larger radius can increase component stiffness and help resist edge chipping, while the 60° triangle provides multiple cutting edges per insert to extend usable life. Selecting the T5115 grade matches the mechanical demands of cast-iron machining by prioritising a durable cutting edge and manageable flank wear, which helps maintain dimensional accuracy across long production runs.

FAQ

Is this insert suitable for machining cast iron?
Yes. The TNMA220416 T5115 insert is a universal grade developed for cast-iron machining, combining wear resistance and edge stability for consistent turning results.

Can the insert be used for internal and external turning?
Yes. The triangular form and geometry allow use in both external and internal turning operations when paired with a compatible holder.

What does the T5115 grade mean for tool life?
The T5115 grade, with a CVD-coated surface and carbide substrate, offers a balance of wear resistance and edge robustness that supports predictable tool life in cast-iron applications.

How does the 1.6 mm corner radius affect the process?
A 1.6 mm corner radius increases edge strength and reduces chipping risk, which helps maintain dimensional stability and surface quality during sustained cutting.

Does the insert fit standard ISO holders?
The ISO designation TNMA220416 indicates standardisation, but final fit depends on holder form, clearance angle, tolerance class, clamping method, size and thickness.
